necessary to ensure that the risk of ignition is minimized. For repair to the refrigerating system,
the following precautions shall be complied with prior to conducting work on the system.
5. Work Procedure
Works shall be undertaken under a controlled procedure so as to minimize the risk of a flammable
gas or vapor being present while the work is being performed.
6. General Work Area
All maintenance staff and others working in the local area shall be instructed on the nature of
work being carried out. Working in confined spaces shall be avoided.
7. Checking For Presence Of Refrigerant
The area shall be checked with an appropriate refrigerant 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. no sparking,
adequately sealed or intrinsically safe.
8. 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 power or CO2 fire
extinguisher adjacent to the charging area.
9. No Ignition Sources
No person carrying out work in relation to a REFRIGERATING SYSTEM which involves exposing
any pipe work 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 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.
10. Ventilated Area
Ensure that the area is in the open or that it is adequately ventilated before breaking into the
system or conducting any work that could produce ignition. Keep ventilation openings clear of
obstruction. Ventilation continue during the period that the work is carried out. Proper ventilation
should safely disperse any released refrigerant and preferably expel it externally into the
atmosphere.
11. Checks To The Refrigeration 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:

R
DURASTAR.COM
9
• 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 circuits shall be checked for the
presence of refrigerant;
• marking to the equipment continues to be visible and legible, marking and signs that are
illegible shall be corrected;
• refrigeration 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.
12. 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, and 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;
• Sealed electrical components shall be replaced if it's damage;
• Intrinsically safe components must be replaced if it's damage.
13. Wiring
Check that wiring 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.
14. 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 refrigerant systems:
• Electronic leak detectors may be used to detect refrigerant leaks but, in the case of
FLAMMABLE REFRIGERANTS, the sensitivity may not be adequate, or may need re-
calibration to a sensitivity of 0.18 oz (5 g) per year. (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 also 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.

R
DURASTAR.COM10
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 o valves) in a part of the system remote from the
leak. See the following instructions for removal of refrigerant.
15. 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:
• safely remove refrigerant following local and national regulations; evacuate;
• purge the circuit with NITROGEN
• evacuate (requirement);
• continuously flush or purge with NITROGEN when using flame to open circuit; and
• 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 (OFN) 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, refrigerant purging shall be achieved by
breaking the vacuum in the system with OXYGEN-FREE NITROGEN (OFN) and continuing to fill
until the working pressure is achieved, then venting to atmosphere, and finally pulling down to
a vacuum (requirement). This process shall be repeated until no refrigerant is within the system
(requirement). When the final oxygen-free nitrogen charge is used, the system shall be vented
down to atmospheric pressure to enable work to take place.
The outlet for the vacuum pump shall not be close to any potential ignition sources, and
ventilation shall be available.
16. Charging Procedures
In addition to conventional charging procedures, the following requirements shall be followed:
• Works shall be undertaken with appropriate tools only (In case of uncertainty, please consult
the manufacturer of the tools for use with flammable refrigerants).
• Ensure that contamination of different refrigerants does not occur when using charging
equipment.
• Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in
them.
• Cylinders shall be kept upright.
• Ensure that the refrigeration system is grounded 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 OXYGEN FREE NITROGEN
• (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.
Note
Examples of leak detection fluids are bubble method and fluorescent method agents.

17. 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 recovered refrigerant. It is essential that electrical power is
available before the task is commenced.
• Become familiar with the equipment and its operation.
• Isolate system electrically
• Before attempting the procedure ensure that:
1. mechanical handling equipment is available, if required, for handling refrigerant cylinders;
2. all personal protective equipment is available and being used correctly;
3. the recovery process is supervised at all times by a competent person;
4. recovery equipment and cylinders conform to the appropriate standards.
• Pump down refrigerant system, if possible.
• If a vacuum is not possible, make a manifold so that refrigerant can be removed from various
parts of the system.
• Make sure that cylinder is situated on the scales before recovery takes place.
• Start the recovery machine and operate in accordance with instructions.
• Do not overfill cylinders (no more than 80 % volume liquid charge)
• Do not exceed the maximum working pressure of the cylinder, even temporarily.
• 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.
• Recovered refrigerant shall not be charged into another refrigeration system unless it has
been cleaned and checked.
18. Labeling
Equipment shall be labeled stating that it has been decommissioned and emptied of refrigerant.
The label shall be dated and signed. For appliances containing FLAMMABLE REFRIGERANTS,
ensure that there are labels on the equipment stating the equipment contains FLAMMABLE
REFRIGERANT.
19. 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 labeled for
that refrigerant (i. e. special cylinders for the recovery of refrigerant). Cylinders shall be complete
with pressure-relief valve and associated shut-o 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 the flammable refrigerant. 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.

R
DURASTAR.COM12
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.
20. Unventilated Areas
• An unventilated area where the appliance using FLAMMABLE REFRIGERANTS is installed
shall be so constructed that should any refrigerant leak, it will not stagnate so as to create a
fire or explosion hazard.
• If appliances connected via an air duct system to one or more rooms with A2L
REFRIGERANTS are installed in a room with an area less than Amin,that room shall be without
continuously operating open flames (e.g. an operating gas appliance) or other POTENTIAL
IGNITION SOURCES (for e.g. an operating electric heater, hot surfaces). A flame-producing
device may be installed in the same space if the device is provided with an active flame arrest.
• Auxiliary devices which may be a POTENTIAL IGNITION SOURCE shall not be installed in
the duct work. Examples of such POTENTIAL IGNITION SOURCES are hot surfaces with a
temperature exceeding 700 °C and electric switching devices.
• Only auxiliary devices(such as certificated heater kit) approved by the appliance manufacturer
or declared suitable with the refrigerant shall be installed in connecting ductwork.
• For duct connected appliances, false ceilings or drop ceilings may be used as a return air
plenum if a REFRIGERANT DETECTION SYSTEM is provided in the appliance and any external
connections are also provided with a sensor immediately below the return air plenum duct
joint.
• REFRIGERANT SENSORS for REFRIGERANT DETECTION SYSTEMS shall only be replaced
with sensors specified by the appliance manufacture.
• LEAK DETECTION SYSTEM installed. Unit must be powered except for service.
21. Transportation, Marking and Storage for Units That Employ Flammable
Refrigerants

additional transportation regulations may exist with respect to equipment containing flammable
gas. The maximum number of pieces of equipment or the configuration of the equipment
permitted to be transported together will be determined by the applicable transport regulations.
Marking of equipment using signs: Signs for similar appliances used in a work area are generally
addressed by local regulations and give the minimum requirements for the provision of safety
and/or health signs for a work location. All required signs are to be maintained and employers
should ensure that employees receive suitable and sufficient instruction and training on the
meaning of appropriate safety signs and the actions that need to be taken in connection with
these signs. The effectiveness of signs should not be diminished by too many signs being placed
together. Any pictograms used should be as simple as possible and contain only essential details.
Disposal of equipment using flammable refrigerants: See national regulations.
Storage of equipment/appliances: The storage of the appliance should be in accordance with

R
DURASTAR.COM

CARE AND MAINTENANCE
MAINTAINING THE INDOOR UNIT
• DO NOT substitute a blown fuse with a higher or lower amperage rating fuse, as this may cause
circuit damage or an electrical fire.
• Make sure the drain hose is set up according to the instructions. Failure to do so could cause
leakage and result in personal property damage, fire, and electrical shock.
• Make sure that all wires are connected properly. Failure to connect wires according to
instructions can result in electrical shock or fire.
CAUTION
• Always turn off the unit and disconnect power before cleaning or maintenance.
• Maintenance and cleaning should only be performed by a certified technician.
Improper repair or maintenance could result in water leakage, electrical shock,
or fire, and may void your warranty.
• Use care when working on the unit at heights.
• Only use a soft, dry cloth to wipe the unit clean. If the unit is especially dirty, you
can use a cloth soaked in warm water to wipe it clean.
CLEANING THE INDOOR UNIT
• Do not use chemicals or chemically treated cloths to clean the unit.
• Do not use benzene, paint thinner, polishing powder or other solvents to clean the unit. They
can cause the plastic surface to crack or deform.
• Do not use water hotter than 104°F (40°C) to clean the front panel. This can cause the panel to
deform or become discolored.
CAUTION
• Before changing the filter or cleaning, turn off the unit and disconnect its power
supply.
• When removing the filter, do not touch the metal parts in the unit. The sharp metal
edges can cut you.
• Do not use water to clean the inside of the indoor unit. This can destroy insulation
and cause electrical shock.
• Do not expose filter to direct sunlight when drying. This can shrink the filter.

COMMON ISSUES
The following problems are not a malfunction and in most situations will not require repairs.
ISSUE POSSIBLE CAUSES
Unit does not turn on
when pressing ON/OFF
button
The unit has a 3-minute protection feature that prevents the unit from
overloading. The unit cannot be restarted within three minutes of being
turned off.
The unit changes from
COOL/HEAT mode to
FAN mode
The unit may change its setting to prevent frost from forming on the
unit. Once the temperature increases, the unit will start operating in the
previously selected mode again.
The set temperature has been reached, at which point the unit
turns off the compressor. The unit will continue operating when the
temperature fluctuates again.
The indoor unit emits
white mist
In humid regions, a large temperature difference between the room’s
air and the conditioned air can cause white mist.
Both the indoor and
outdoor units emit
white mist
When the unit restarts in HEAT mode after defrosting, white mist may
be emitted due to moisture generated during the defrosting process.
The indoor unit makes
noises
A rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in HEAT mode due
to expansion and contraction of the unit’s plastic parts.

R
DURASTAR.COM
33
ISSUE POSSIBLE CAUSES
Both the indoor unit
and outdoor unit make
noises
Low hissing sound during operation: This is normal and is caused by
refrigerant gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running,
or is defrosting: This noise is normal and is caused by the refrigerant
gas stopping or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and
metal parts caused by temperature changes during operation can
cause squeaking noises.
The outdoor unit
makes noises
The unit will make different sounds based on its current operating
mode.
Dust is emitted from
either the indoor or
outdoor unit
The unit may accumulate dust during extended periods of non-use,
which will be emitted when the unit is turned on. This can be mitigated
by covering the unit during long periods of inactivity.
The unit emits a bad
odor
The unit may absorb odors from the environment (such as furniture,
cooking, cigarettes, etc.) which will be emitted during operations.
The unit’s filters have become moldy and should be cleaned.
The fan of the outdoor
unit does not operate
During operation, the fan speed is controlled to optimize product
operation.
Operation is erratic,
unpredictable, or unit is
unresponsive
Interference from cell phone towers and remote boosters may cause
the unit to malfunction. In this case, try the following:
• Disconnect the power, then reconnect.
• Press ON/OFF button on remote control to restart operation.
NOTE
If problem persists, contact a local dealer or your nearest customer service center.
Provide them with a detailed description of the unit malfunction as well as your model
number.
