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
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
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
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
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

reclaimed refrigerant. It is essential that
electrical power is available before the
task is commenced.
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

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);
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
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

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
equipment are closed off.
k) Recovered refrigerant shall not be
charged into another refrigeration system
unless it has been cleaned and checked.

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
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

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
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.

reclaimed refrigerant. It is essential that
electrical power is available before the
task is commenced.
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);
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
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
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.
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
equipment are closed off.
k) Recovered refrigerant shall not be
charged into another refrigeration system
unless it has been cleaned and checked.
14.

decommissioning, it is recommended
good practice that all refrigerants are
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
checks and component inspection
procedures. If a fault exists that could
compromise safety, then no electrical
supply shall be connected to the circuit

11LOCATION & HOW IT WORKS
How It Works
When the unit is started, the fan begins to
pull moisture-laden air across the
dehumidifying coils. The coils condense or
draw moisture from the air, and air flows
through the air outlet louvers into the room
as dry, warm air. Moisture removed from air is
collected in a bucket on the front of the
dehumidifier.
The unit is designed to operate between 41°F
(5°C), and 89°F (32°C) and between
30%(RH) and 80%(RH). The unit will not
work properly if the temperature is out of this
temperature range, or the performance of
the unit will fall greatly.
The "Compressor" circuit has an automatic 3
minute time delayed start if the unit is turned
o and on quickly. This prevents overheating
of the compressor and possible circuit
breaker tripping. Make sure the tank is fitted
correctly otherwise unit will not turn on.
Unpacking
Slider out the water bucket.
Note: If the casters are not installed, wearing
gloves to prevent fingers from being scraped
by the ground.
IMPORTANT:
1. Dehumidifier must be operated in an
enclosed area to be most eective. Close
all doors, windows, and other outside
openings to the room. The eectiveness of
the dehumidifier depends on the rate at
which new moisture-laden air enters the
room.
2. Place dehumidifier in a location that does
not restrict the airflow of the air intake and
air outlet.
3. A dehumidifier operating in a basement
will have little or no eect in drying an
adjacent enclosed storage area, such as a
closet, unless there is adequate circulation
of air in and out of the area. lt may be
necessary to install a second dehumidifier
in the enclosed area for satisfactory drying.
4. The dehumidifier must be installed on a
level floor that will support it with a full
bucket of water.
5. There should be a minimum of 15.75 inches
clearance around the dehumidifier. The
unit will produce heat while in operation
and should not be operated in an enclosed
small space like a closet.
