permitted to be stored together will be
determined by local regulations.
6. Information on servicing
a) Checks to the area
Prior to beginning work on systems
containing flammable refrigerants, safety
checks are necessary to ensure that the
risk of ignition is minimised. For repair to
the refrigerating system, the following
precautions shall be complied with prior
to conducting work on the system.
b) Work procedure
Work shall be undertaken under a
controlled procedure so as to minimise
the risk of a flammable gas or vapour
being present while the work is being
performed.
c) General work area
All maintenance staff and others working
in the local area shall be instructed on
the nature of work being carried out.
Work in confined spaces shall be
avoided. The area around the workspace
shall be sectioned off. Ensure that the
conditions within the area have been
made safe by control of flammable
material.
d) Checking for presence of refrigerant
The area shall be checked with an
appropriate refrigerating detector prior
to and during work, to ensure the
technician is aware of potentially
flammable atmospheres. Ensure that the
leak detection equipment being used is
suitable for use with flammable
refrigerants, i.e. non-sparking,
adequately sealed or intrinsically safe.
e) Presence of fire extinguisher
If any hot work is to be conducted on the
refrigeration equipment or any
circuit is being used, the secondary circuit
shall be checked for the presence of
refrigerant; Marking to the equipment
continues to be visible and legible.
Markings and signs that are illegible shall
be corrected; Refrigerating pipe or
components are installed in a position
where they are unlikely to be exposed to
any substance which may corrode
refrigerant containing components,
unless the components are constructed
of materials which are inherently resistant
to being corroded or are suitably
protected against being so corroded.
i) Checks to electrical devices
Repair and maintenance to electrical
components shall include initial safety
checks and component inspection
procedures. If a fault exists that could
compromise safety, then no electrical
supply shall be connected to the circuit
until it is satisfactorily dealt with. If the
fault cannot be corrected immediately
but it is necessary to continue operation,
an adequate temporary solution shall be
used. This shall be reported to the owner
of the equipment so all parties are
advised. Initial safety checks shall include:
That capacitors are discharged: this shall
be done in a safe manner to avoid
possibility of sparking; That there no live
electrical components and wiring are
exposed while charging, recovering or
purging the system; That there is
continuity of earth bonding.
7. Sealed electrical components shall be
replaced.
8. Intrinsically safe components must be
replaced.
9. Cabling
Check that cabling will not be subject to
wear, corrosion, excessive pressure,
vibration, sharp edges or any other
adverse environmental effects. The check
shall also take into account the effects of
aging or continual vibration from sources
such as compressors or fans.
10.Detection of flammable refrigerants
Under no circumstances shall potential
sources of ignition be used in the
e) continuously flush or purge with inert
gas when using flame to open circuit;
and;
f) open the circuit.
The refrigerant charge shall be recovered
into the correct recovery cylinders if
venting is not allowed by local and
national codes. For appliances containing
flammable refrigerants, the system shall
be purged with oxygen-free nitrogen to
render the appliance safe for flammable
refrigerants. This process might need to
be repeated several times. Compressed
air or oxygen shall not be used for
purging refrigerant systems. For
appliances containing flammable
refrigerants, refrigerants purging shall be
achieved by breaking the vacuum in the
system with oxygen-free nitrogen and
continuing to fill until the working
pressure is achieved, then venting to
atmosphere, and finally pulling down to a
vacuum (optional for A2L). This process
shall be repeated until no refrigerant is
within the system (optional for A2L).
When the final oxygen-free nitrogen
charge is used, the system shall be vented
down to atmospheric pressure to enable
work to take place. Ensure that the outlet
for the vacuum pump is not close to any
potential ignition sources and that
ventilation is available.
12. Charging procedures
In addition to conventional charging
procedures, the following requirements
shall be followed. Ensure that
contamination of different refrigerants
does not occur when using charging
equipment. Hoses or lines shall be as
short as possible to minimise the amount
of refrigerant contained in them.
Cylinders shall be kept in an appropriate
position according to the instructions.
Ensure that the refrigeration system is
earthed prior to charging the system with
refrigerant. Label the system when
charging is complete (if not already).
Extreme care shall be taken not to overfill
the refrigeration system. Prior to
recharging the system it shall be pressure
searching for or detection of refrigerant
leaks. A halide torch (or any other
detector using a naked flame) shall not be
used.
The following leak detection methods are
deemed acceptable for systems
containing flammable refrigerants.
Electronic leak detectors shall be used to
detect flammable refrigerants, but the
sensitivity may not be adequate, or may
need re-calibration. (Detection
equipment shall be calibrated in a
refrigerant-free area). Ensure that the
detector is not a potential source of
ignition and is suitable for the refrigerant
used. Leak detection equipment shall be
set at a percentage of the LFL of the
refrigerant and shall be calibrated to the
refrigerant employed and the appropriate
percentage of gas (25 % maximum) is
confirmed. Leak detection fluids are
suitable for use with most refrigerants but
the use of detergents containing chlorine
shall be avoided as the chlorine may react
with the refrigerant and corrode the
copper pipe-work. If a leak is suspected,
all naked flames shall be
removed/extinguished. If a leakage of
refrigerant is found which requires
brazing, all of the refrigerant shall be
recovered from the system, or isolated
(by means of shut off valves) in a part of
the system remote from the leak.
Removal of refrigerant shall be according
to Removal and evacuation.
11. Removal and evacuation
When breaking into the refrigerant circuit
to make repairs – or for any other
purpose–conventional procedures shall
be used. However, for flammable
refrigerants it is important that best
practice be followed, since flammability is
a consideration. The following procedure
shall be adhered to:
a) Safely remove refrigerant following
local and national regulations;
b) Evacuate;
c) Purge the circuit with inert gas
(optional for A2L);
d) Evacuate (optional for A2L);

decommissioning, it is recommended
good practice that all refrigerants are
removed safely. When transferring
refrigerant into cylinders, ensure that only
appropriate refrigerant recovery
cylinders are employed. Ensure that the
correct number of cylinders for holding
the total system charge is available. All
cylinders to be used are designated for
the recovered refrigerant and labelled for
that refrigerant (i.e. special cylinders for
the recovery of refrigerant). Cylinders
shall be complete with pressure relief
valve and associated shut-off valves in
good working order. Empty recovery
cylinders are evacuated and, if possible,
cooled before recovery occurs.
The recovery equipment shall be in good
working order with a set of instructions

5. Storage of packed (unsold) equipment
Storage package protection should be
constructed such that mechanical
damage to the equipment inside the
package will not cause a leak of the
refrigerant charge. The maximum
number of pieces of equipment
permitted to be stored together will be
determined by local regulations.
6. Information on servicing
a) Checks to the area
Prior to beginning work on systems
containing flammable refrigerants, safety
checks are necessary to ensure that the
risk of ignition is minimised. For repair to
the refrigerating system, the following
precautions shall be complied with prior
to conducting work on the system.
b) Work procedure
Work shall be undertaken under a
controlled procedure so as to minimise
the risk of a flammable gas or vapour
being present while the work is being
performed.
c) General work area
All maintenance staff and others working
in the local area shall be instructed on
the nature of work being carried out.
Work in confined spaces shall be
avoided. The area around the workspace
shall be sectioned off. Ensure that the
conditions within the area have been
made safe by control of flammable
material.
d) Checking for presence of refrigerant
The area shall be checked with an
appropriate refrigerating detector prior
to and during work, to ensure the
technician is aware of potentially
flammable atmospheres. Ensure that the
leak detection equipment being used is
suitable for use with flammable
refrigerants, i.e. non-sparking,
adequately sealed or intrinsically safe.
e) Presence of fire extinguisher
If any hot work is to be conducted on the
refrigeration equipment or any
associated parts, appropriate fire
extinguishing equipment shall be
available to hand. Have a dry powder or
CO2 fire extinguisher adjacent to the
charging area.
f) No ignition sources
No person carrying out work in relation to
a refrigerating system which involves
exposing any pipe work that contains or
has contained flammable refrigerant shall
use any sources of ignition in such a
manner that it may lead to the risk of fire
or explosion. All possible ignition sources,
including cigarette smoking, should be
kept sufficiently far away from the site of
installation, repairing, removing and
disposal, during which flammable
refrigerant can possibly be released to
the surrounding space. Prior to work
taking place, the area around the
equipment is to be surveyed to make sure
that there are no flammable hazards or
ignition risks. No Smoking signs shall be
displayed.
g) Ventilated area
Ensure that the area is in the open or that
it is adequately ventilated before
breaking into the system or conducting
any hot work. A degree of ventilation shall
continue during the period that the work
is carried out. The ventilation should
safely disperse any released refrigerant
and preferably expel it externally into the
atmosphere.
h) Checks to the refrigerating equipment
Where electrical components are being
changed, they shall be fit for the purpose
and to the correct specification. At all
times the manufacturer's maintenance
and service guidelines shall be followed. If
in doubt consult the manufacturer's
technical department for assistance. The
following checks shall be applied to
installations using flammable refrigerants:
The actual refrigerant charge is in
accordance with the room size within
which the refrigerant containing parts are
installed; The ventilation machinery and
outlets are operating adequately and are
not obstructed; If an indirect refrigerating
circuit is being used, the secondary circuit
shall be checked for the presence of
refrigerant; Marking to the equipment
continues to be visible and legible.
Markings and signs that are illegible shall
be corrected; Refrigerating pipe or
components are installed in a position
where they are unlikely to be exposed to
any substance which may corrode
refrigerant containing components,
unless the components are constructed
of materials which are inherently resistant
to being corroded or are suitably
protected against being so corroded.
i) Checks to electrical devices
Repair and maintenance to electrical
components shall include initial safety
checks and component inspection
procedures. If a fault exists that could
compromise safety, then no electrical
supply shall be connected to the circuit
until it is satisfactorily dealt with. If the
fault cannot be corrected immediately
but it is necessary to continue operation,
an adequate temporary solution shall be
used. This shall be reported to the owner
of the equipment so all parties are
advised. Initial safety checks shall include:
That capacitors are discharged: this shall
be done in a safe manner to avoid
possibility of sparking; That there no live
electrical components and wiring are
exposed while charging, recovering or
purging the system; That there is
continuity of earth bonding.
7. Sealed electrical components shall be
replaced.
8. Intrinsically safe components must be
replaced.
9. Cabling
Check that cabling will not be subject to
wear, corrosion, excessive pressure,
vibration, sharp edges or any other
adverse environmental effects. The check
shall also take into account the effects of
aging or continual vibration from sources
such as compressors or fans.
10.Detection of flammable refrigerants
Under no circumstances shall potential
sources of ignition be used in the
7IMPORTANT SAFETY INSTRUCTIONS
e) continuously flush or purge with inert
gas when using flame to open circuit;
and;
f) open the circuit.
The refrigerant charge shall be recovered
into the correct recovery cylinders if
venting is not allowed by local and
national codes. For appliances containing
flammable refrigerants, the system shall
be purged with oxygen-free nitrogen to
render the appliance safe for flammable
refrigerants. This process might need to
be repeated several times. Compressed
air or oxygen shall not be used for
purging refrigerant systems. For
appliances containing flammable
refrigerants, refrigerants purging shall be
achieved by breaking the vacuum in the
system with oxygen-free nitrogen and
continuing to fill until the working
pressure is achieved, then venting to
atmosphere, and finally pulling down to a
vacuum (optional for A2L). This process
shall be repeated until no refrigerant is
within the system (optional for A2L).
When the final oxygen-free nitrogen
charge is used, the system shall be vented
down to atmospheric pressure to enable
work to take place. Ensure that the outlet
for the vacuum pump is not close to any
potential ignition sources and that
ventilation is available.
12. Charging procedures
In addition to conventional charging
procedures, the following requirements
shall be followed. Ensure that
contamination of different refrigerants
does not occur when using charging
equipment. Hoses or lines shall be as
short as possible to minimise the amount
of refrigerant contained in them.
Cylinders shall be kept in an appropriate
position according to the instructions.
Ensure that the refrigeration system is
earthed prior to charging the system with
refrigerant. Label the system when
charging is complete (if not already).
Extreme care shall be taken not to overfill
the refrigeration system. Prior to
recharging the system it shall be pressure
searching for or detection of refrigerant
leaks. A halide torch (or any other
detector using a naked flame) shall not be
used.
The following leak detection methods are
deemed acceptable for systems
containing flammable refrigerants.
Electronic leak detectors shall be used to
detect flammable refrigerants, but the
sensitivity may not be adequate, or may
need re-calibration. (Detection
equipment shall be calibrated in a
refrigerant-free area). Ensure that the
detector is not a potential source of
ignition and is suitable for the refrigerant
used. Leak detection equipment shall be
set at a percentage of the LFL of the
refrigerant and shall be calibrated to the
refrigerant employed and the appropriate
percentage of gas (25 % maximum) is
confirmed. Leak detection fluids are
suitable for use with most refrigerants but
the use of detergents containing chlorine
shall be avoided as the chlorine may react
with the refrigerant and corrode the
copper pipe-work. If a leak is suspected,
all naked flames shall be
removed/extinguished. If a leakage of
refrigerant is found which requires
brazing, all of the refrigerant shall be
recovered from the system, or isolated
(by means of shut off valves) in a part of
the system remote from the leak.
Removal of refrigerant shall be according
to Removal and evacuation.
11. Removal and evacuation
When breaking into the refrigerant circuit
to make repairs – or for any other
purpose–conventional procedures shall
be used. However, for flammable
refrigerants it is important that best
practice be followed, since flammability is
a consideration. The following procedure
shall be adhered to:
a) Safely remove refrigerant following
local and national regulations;
b) Evacuate;
c) Purge the circuit with inert gas
(optional for A2L);
d) Evacuate (optional for A2L);
equipment are closed off.
k) Recovered refrigerant shall not be
charged into another refrigeration system
unless it has been cleaned and checked.

When removing refrigerant from a
system, either for servicing or
decommissioning, it is recommended
good practice that all refrigerants are
removed safely. When transferring
refrigerant into cylinders, ensure that only
appropriate refrigerant recovery
cylinders are employed. Ensure that the
correct number of cylinders for holding
the total system charge is available. All
cylinders to be used are designated for
the recovered refrigerant and labelled for
that refrigerant (i.e. special cylinders for
the recovery of refrigerant). Cylinders
shall be complete with pressure relief
valve and associated shut-off valves in
good working order. Empty recovery
cylinders are evacuated and, if possible,
cooled before recovery occurs.
The recovery equipment shall be in good
working order with a set of instructions
concerning the equipment that is at hand
and shall be suitable for the recovery of
flammable refrigerants. If in doubt, the
manufacturer should be consulted. In
addition, a set of calibrated weighing
scales shall be available and in good
working order. Hoses shall be complete
with leak-free disconnect couplings and
in good condition.
The recovered refrigerant shall be
processed according to local legislation in
the correct recovery cylinder, and the
relevant waste transfer note arranged.
Do not mix refrigerants in recovery units
and especially not in cylinders.
If compressors or compressor oils are to
be removed, ensure that they have been
tested with OFN. The system shall be leak
tested on completion of charging but
prior to commissioning. A follow up leak
test shall be carried out prior to leaving
the site.
13. Decommissioning
Before carrying out this procedure, it is
essential that the technician is completely
familiar with the equipment and all its

c) Before attempting the procedure ensure
that: Mechanical handling equipment is
available, if required, for handling
refrigerant cylinders; All personal
protective equipment is available and
being used correctly; The recovery
process is supervised at all times by a
competent person; Recovery equipment
and cylinders conform to the appropriate
standards.
d) Pump down refrigerant system, if
possible.
e) If a vacuum is not possible, make a
manifold so that refrigerant can be
removed from various parts of the
system.
f) Make sure that cylinder is situated on the
scales before recovery takes place.
g) Start the recovery machine and operate
in accordance with instructions.
h) Do not overfill cylinders. (No more than
80% volume liquid charge).

evacuated to an acceptable level to make
certain that flammable refrigerant does
not remain within the lubricant. The
compressor body shall not be heated by
an open flame or other ignition sources to
accelerate this process. When oil is
drained from a system, it shall be carried
out safely.
regulations or instructions, whichever is
more stringent.
5. Storage of packed (unsold) equipment
Storage package protection should be
constructed such that mechanical
damage to the equipment inside the
package will not cause a leak of the
refrigerant charge. The maximum
number of pieces of equipment
permitted to be stored together will be
determined by local regulations.
6. Information on servicing
a) Checks to the area
Prior to beginning work on systems
containing flammable refrigerants, safety
checks are necessary to ensure that the
risk of ignition is minimised. For repair to
the refrigerating system, the following
precautions shall be complied with prior
to conducting work on the system.
b) Work procedure
Work shall be undertaken under a
controlled procedure so as to minimise
the risk of a flammable gas or vapour
being present while the work is being
performed.
c) General work area
All maintenance staff and others working
in the local area shall be instructed on
the nature of work being carried out.
Work in confined spaces shall be
avoided. The area around the workspace
shall be sectioned off. Ensure that the
conditions within the area have been
made safe by control of flammable
material.
d) Checking for presence of refrigerant
The area shall be checked with an
appropriate refrigerating detector prior
to and during work, to ensure the
technician is aware of potentially
flammable atmospheres. Ensure that the
leak detection equipment being used is
suitable for use with flammable
refrigerants, i.e. non-sparking,
adequately sealed or intrinsically safe.
e) Presence of fire extinguisher
If any hot work is to be conducted on the
refrigeration equipment or any
circuit is being used, the secondary circuit
shall be checked for the presence of
refrigerant; Marking to the equipment
continues to be visible and legible.
Markings and signs that are illegible shall
be corrected; Refrigerating pipe or
components are installed in a position
where they are unlikely to be exposed to
any substance which may corrode
refrigerant containing components,
unless the components are constructed
of materials which are inherently resistant
to being corroded or are suitably
protected against being so corroded.
i) Checks to electrical devices
Repair and maintenance to electrical
components shall include initial safety
checks and component inspection
procedures. If a fault exists that could
compromise safety, then no electrical
supply shall be connected to the circuit
until it is satisfactorily dealt with. If the
fault cannot be corrected immediately
but it is necessary to continue operation,
an adequate temporary solution shall be
used. This shall be reported to the owner
of the equipment so all parties are
advised. Initial safety checks shall include:
That capacitors are discharged: this shall
be done in a safe manner to avoid
possibility of sparking; That there no live
electrical components and wiring are
exposed while charging, recovering or
purging the system; That there is
continuity of earth bonding.
7. Sealed electrical components shall be
replaced.
8. Intrinsically safe components must be
replaced.
9. Cabling
Check that cabling will not be subject to
wear, corrosion, excessive pressure,
vibration, sharp edges or any other
adverse environmental effects. The check
shall also take into account the effects of
aging or continual vibration from sources
such as compressors or fans.
10.Detection of flammable refrigerants
Under no circumstances shall potential
sources of ignition be used in the
e) continuously flush or purge with inert
gas when using flame to open circuit;
and;
f) open the circuit.
The refrigerant charge shall be recovered
into the correct recovery cylinders if
venting is not allowed by local and
national codes. For appliances containing
flammable refrigerants, the system shall
be purged with oxygen-free nitrogen to
render the appliance safe for flammable
refrigerants. This process might need to
be repeated several times. Compressed
air or oxygen shall not be used for
purging refrigerant systems. For
appliances containing flammable
refrigerants, refrigerants purging shall be
achieved by breaking the vacuum in the
system with oxygen-free nitrogen and
continuing to fill until the working
pressure is achieved, then venting to
atmosphere, and finally pulling down to a
vacuum (optional for A2L). This process
shall be repeated until no refrigerant is
within the system (optional for A2L).
When the final oxygen-free nitrogen
charge is used, the system shall be vented
down to atmospheric pressure to enable
work to take place. Ensure that the outlet
for the vacuum pump is not close to any
potential ignition sources and that
ventilation is available.
12. Charging procedures
In addition to conventional charging
procedures, the following requirements
shall be followed. Ensure that
contamination of different refrigerants
does not occur when using charging
equipment. Hoses or lines shall be as
short as possible to minimise the amount
of refrigerant contained in them.
Cylinders shall be kept in an appropriate
position according to the instructions.
Ensure that the refrigeration system is
earthed prior to charging the system with
refrigerant. Label the system when
charging is complete (if not already).
Extreme care shall be taken not to overfill
the refrigeration system. Prior to
recharging the system it shall be pressure
searching for or detection of refrigerant
leaks. A halide torch (or any other
detector using a naked flame) shall not be
used.
The following leak detection methods are
deemed acceptable for systems
containing flammable refrigerants.
Electronic leak detectors shall be used to
detect flammable refrigerants, but the
sensitivity may not be adequate, or may
need re-calibration. (Detection
equipment shall be calibrated in a
refrigerant-free area). Ensure that the
detector is not a potential source of
ignition and is suitable for the refrigerant
used. Leak detection equipment shall be
set at a percentage of the LFL of the
refrigerant and shall be calibrated to the
refrigerant employed and the appropriate
percentage of gas (25 % maximum) is
confirmed. Leak detection fluids are
suitable for use with most refrigerants but
the use of detergents containing chlorine
shall be avoided as the chlorine may react
with the refrigerant and corrode the
copper pipe-work. If a leak is suspected,
all naked flames shall be
removed/extinguished. If a leakage of
refrigerant is found which requires
brazing, all of the refrigerant shall be
recovered from the system, or isolated
(by means of shut off valves) in a part of
the system remote from the leak.
Removal of refrigerant shall be according
to Removal and evacuation.
11. Removal and evacuation
When breaking into the refrigerant circuit
to make repairs – or for any other
purpose–conventional procedures shall
be used. However, for flammable
refrigerants it is important that best
practice be followed, since flammability is
a consideration. The following procedure
shall be adhered to:
a) Safely remove refrigerant following
local and national regulations;
b) Evacuate;
c) Purge the circuit with inert gas
(optional for A2L);
d) Evacuate (optional for A2L);
equipment are closed off.
k) Recovered refrigerant shall not be
charged into another refrigeration system
unless it has been cleaned and checked.
14.
Labelling
Equipment shall be labelled stating that it
has been de-commissioned and emptied
of refrigerant. The label shall be dated
and signed. Ensure that there are labels
on the equipment stating the equipment
contains flammable refrigerant.
15. Recovery
When removing refrigerant from a
system, either for servicing or
decommissioning, it is recommended
good practice that all refrigerants are
removed safely. When transferring
refrigerant into cylinders, ensure that only
appropriate refrigerant recovery
cylinders are employed. Ensure that the
correct number of cylinders for holding
the total system charge is available. All
cylinders to be used are designated for
the recovered refrigerant and labelled for
that refrigerant (i.e. special cylinders for
the recovery of refrigerant). Cylinders
shall be complete with pressure relief
valve and associated shut-off valves in
good working order. Empty recovery
cylinders are evacuated and, if possible,
cooled before recovery occurs.
The recovery equipment shall be in good
working order with a set of instructions
concerning the equipment that is at hand
and shall be suitable for the recovery of
flammable refrigerants. If in doubt, the
manufacturer should be consulted. In
addition, a set of calibrated weighing
scales shall be available and in good
working order. Hoses shall be complete
with leak-free disconnect couplings and
in good condition.
The recovered refrigerant shall be
processed according to local legislation in
the correct recovery cylinder, and the
relevant waste transfer note arranged.
Do not mix refrigerants in recovery units
and especially not in cylinders.
If compressors or compressor oils are to
be removed, ensure that they have been
tested with OFN. The system shall be leak
tested on completion of charging but
prior to commissioning. A follow up leak
test shall be carried out prior to leaving
the site.
13. Decommissioning
Before carrying out this procedure, it is
essential that the technician is completely
familiar with the equipment and all its
detail. It is recommended good practice
that all refrigerants are recovered safely.
Prior to the task being carried out, an oil
and refrigerant sample shall be taken in
case analysis is required prior to re-use of
reclaimed refrigerant. It is essential that
electrical power is available before the
task is commenced.
a) Become familiar with the equipment and
its operation.
b) Isolate system electrically.
c) Before attempting the procedure ensure
that: Mechanical handling equipment is
available, if required, for handling
refrigerant cylinders; All personal
protective equipment is available and
being used correctly; The recovery
process is supervised at all times by a
competent person; Recovery equipment
and cylinders conform to the appropriate
standards.
d) Pump down refrigerant system, if
possible.
e) If a vacuum is not possible, make a
manifold so that refrigerant can be
removed from various parts of the
system.
f) Make sure that cylinder is situated on the
scales before recovery takes place.
g) Start the recovery machine and operate
in accordance with instructions.
h) Do not overfill cylinders. (No more than
80% volume liquid charge).
i) Do not exceed the maximum working
pressure of the cylinder, even
temporarily.
j) When the cylinders have been filled
correctly and the process completed,
make sure that the cylinders and the
equipment are removed from site
promptly and all isolation valves on the
evacuated to an acceptable level to make
certain that flammable refrigerant does
not remain within the lubricant. The
compressor body shall not be heated by
an open flame or other ignition sources to
accelerate this process. When oil is
drained from a system, it shall be carried
out safely.

overheating of the compressor and possible
circuit breaker tripping. The fan will
continue to run during this time.
• There is a 2-Second delay for the
compressor shutting down when selecting
FAN ONLY. This is to cover the possibility
of having to roll through to select another
mode.
• The control will maintain the set
temperature within 2 degrees Fahrenheit,
between 60°F and 90°F degrees.
• After a power outage, the unit will
memorize the last setting and return the
unit to the same setting once power is
restored.
• The unit should be operated in a
temperature range of indoor side 60°F -
90°F (16°C - 32°C), outdoor side 64°F -
