breaker. Read electrical ratings on unit’s rating plate. Proper circuit
protection is the responsibility of the homeowner. Grounding – Unit MUST be
grounded from branch circuit through service cord to unit, or through separate
ground wire provided on permanently connected units. Be sure that branch
circuit or general purpose outlet is grounded. Receptacle – The field supplied
outlet must match plug on service cord and be within reach of service cord. Do
NOT alter the service cord or plug. Do NOT use an extension cord. Refer to the
table above for proper receptacle and fuse type. Make sure the wiring is
adequate for your unit. If you have fuses, they should be of the time delay
type. Before you install or relocate this unit, be sure that the amperage
rating of the circuit breaker or time delay fuse does not exceed the amp
rating listed in Table 206. DO NOT use an extension cord. The cord provided
will carry the proper amount of electrical power to the unit; an extension
cord may not. Make sure that the receptacle is compatible with the air
conditioner cord plug provided. Proper grounding must be maintained at all
times. Two prong receptacles must be replaced with a grounded receptacle by a

- The indoor fan runs at the set speed when processing in sleep mode, after
the first change, unit changes to medium speed if the preset is in high
operation, and the medium and low speed preset will keep the original even
after the first change. 10 hours later AC quits from sleep mode and runs at
former set fan speed 2) Processing SLEEP mode, the vane works according to the
preset, 10 hours later AC quits from sleep and works as the former preset. 3)
The set fan speed refers to the preset value before processing SLEEP mode. If
the unit just on stand by before sleep operation, the set value to be
according to low speed. if AC preset in super speed, the set value will change
to high speed, while in Auto wind, it change to low speed. Sleep process
control 1) If the set temperature is changed during the period of sleep mode,
it is also executed as the initial sleep set, and the change time is reset to
0, the temperature change will be restarted, but the 10 hours running time
will not be reset as 0, it will accumulate continuously. 2) The fan speed can
not be changed during sleep mode. 3) During the sleep period in cooling mode,
the new set will be executed if the vane work status is changed, the anti-cold
angle will not be executed. 4) During the sleep period in heating mode, the
wind speed and vane swinging for cold air prevention function is selected
first. 7. Auto Restart Function (Optional) . 7.1 PCB with auto restart
function will keep the operation parameters in EEPROM even with power off. And
the unit can restore operation as the former status automatically while power

OPERATION
General Knowledge Sequence Of Refrigeration
A good understanding of the basic operation of the refrigeration system is
essential for the service technician. Without this understanding, accurate
troubleshooting of refrigeration system problems will be more difficult and
time consuming, if not (in some cases) entirely impossible. The refrigeration
system uses four basic principles (laws) in its operation they are as follows:
1. “Heat always flows from a warmer body to a cooler body.”
2. “Heat must be added to or removed from a substance before a change in state can occur”
3. “Flow is always from a higher pressure area to a lower pressure area.”
4. “The temperature at which a liquid or gas changes state is dependent upon the pressure.”
The refrigeration cycle begins at the compressor. Starting the compressor creates a low pressure in the suction line which draws refrigerant gas (vapor) into the compressor. The compressor then “compresses” this refrigerant vapor, raising its pressure and its (heat intensity) temperature.
The refrigerant leaves the compressor through the discharge Line as a hot High pressure gas (vapor). The refrigerant enters the condenser coil where it gives up some of its heat. The condenser fan moving air across the coil’s finned surface facilitates the transfer of heat from the refrigerant to the relatively cooler outdoor air. When a sufficient quantity of heat has been removed from the refrigerant gas (vapor), the refrigerant will “condense” (i.e. change to a liquid). Once the refrigerant has been condensed (changed) to a liquid it is cooled even further by the air that continues to flow across the condenser coil.
The design determines at exactly what point (in the condenser) the change of state (i.e. gas to a liquid) takes place. In all cases, however, the refrigerant must be totally condensed (changed) to a Liquid before leaving the condenser coil.
The refrigerant leaves the condenser Coil through the liquid line as a warm high pressure liquid. It next will pass through the refrigerant drier (if equipped). It is the function of the drier to trap any moisture present in the system, contaminants, and large particulate matter.
The liquid refrigerant next enters the metering device. The metering device is a capillary tube. The purpose of the metering device is to “meter” (i.e. control or measure) the quantity of refrigerant entering the evaporator coil. In the case of the capillary tube this is accomplished (by design) through size (and length) of device, and the pressure difference present across the device.
Since the evaporator coil is under a lower pressure (due to the suction created by the compressor) than the liquid line, the liquid refrigerant leaves the metering device entering the evaporator coil. As it enters the evaporator coil, the larger area and lower pressure allows the refrigerant to expand and lower its temperature (heat intensity). This expansion is often referred to as “boiling” or atomizing. Since the unit’s blower is moving indoor air across the finned surface of the evaporator coil, the expanding refrigerant absorbs some of that heat. This results in a lowering of the indoor air temperature, or cooling.
The expansion and absorbing of heat cause the liquid refrigerant to evaporate (i.e. change to a gas). Once the refrigerant has been evaporated (changed to a gas), it is heated even further by the air that continues to flow across the evaporator coil.
The particular system design determines at exactly what point (in the evaporator) the change of state (i.e. liquid to a gas) takes place. In all cases, however, the refrigerant must be totally evaporated (changed) to a gas before leaving the evaporator coil.
The low pressure (suction) created by the compressor causes the refrigerant to leave the evaporator through the suction line as a cool low pressure
vapor. The refrigerant then returns to the compressor, where the cycle is
repeated.

TROUBLESHOOTING
Undercharged Refrigerant Systems
WARNING
RISK OF ELECTRIC SHOCK Unplug and/or disconnect all electrical power to the
unit before performing inspections, maintenances or service.
Failure to do so could result in electric shock, serious injury or death.
NOTE: Ensure fan is on high speed during testing. An undercharged system will
result in poor performance (low pressures, etc.) in both the heating and
cooling cycle.
Whenever you service a unit with an undercharge of refrigerant, always suspect
a leak. The leak must be repaired before charging the unit.
To check for an undercharged system, turn the unit on, allow the compressor to
run long enough to establish working pressures in the system (15 to 20
minutes).
WARNING
HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil
under high pressure.
Proper safety procedures must be followed, and proper protective clothing must
be worn when working with refrigerants.
Failure to follow these procedures could result in serious injury or death.
During the cooling cycle you can listen carefully at the exit of the metering device into the evaporator; an intermittent hissing and gurgling sound indicates a low refrigerant charge. Intermittent frosting and thawing of the evaporator is another indication of a low charge, however, frosting and thawing can also be caused by insufficient air over the evaporator. Checks for an undercharged system can be made at the compressor. If the compressor seems quieter than normal, it is an indication of a low refrigerant charge. If the compressor reads low amperage and has a high discharge line temperature at the compressor, it is an indication of low system refrigerant.
A check of the amperage drawn by the compressor motor should show a lower reading. (Check the Unit Specification.) After the unit has run 10 to 15 minutes, check the gauge pressures. Gauges connected to system with an undercharge will have low head pressures and substantially low suction pressures.
Figure 607 (Undercharged System) 30
TROUBLESHOOTING
Overcharged Refrigerant Systems
WARNING
RISK OF ELECTRIC SHOCK Unplug and/or disconnect all electrical power to the
unit before performing inspections, maintenances or service.
Failure to do so could result in electric shock, serious injury or death.
NOTE: Ensure fan is on high speed during testing. Compressor amps will be near
normal or higher. Noncondensables can also cause these symptoms. To confirm,
remove some of the charge, if conditions improve, system may be overcharged.
If conditions don’t improve, Noncondensables are indicated.
NOTE:Factory sealed units will not be overcharged
Whenever an overcharged system is indicated, always make sure that the problem
is not caused by air flow problems. Improper air flow over the evaporator coil
may indicate some of the same symptoms as an over charged system.
WARNING
HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil
under high pressure.
Proper safety procedures must be followed, and proper protective clothing must
be worn when working with refrigerants.
An overcharge can cause the compressor to fail, since it would be “slugged” with liquid refrigerant. The charge for any system is critical. When the compressor is noisy, suspect an overcharge, when you are sure that the air quantity over the evaporator coil is correct. Icing of the evaporator will not be encountered because the refrigerant will boil later if at all. Gauges connected to system will usually have higher head pressure (depending upon amount of over charge). Suction pressure should be slightly higher.
Failure to follow these procedures could result in serious injury or death.
Figure 608 (Overcharged System) 31
TROUBLESHOOTING
Restricted Refrigerant System
NOTE: Ensure fan is on high speed during testing. Troubleshooting a restricted
refrigerant system can be difficult. The following procedures are the more
common problems and solutions to these problems. There are two types of
refrigerant restrictions: Partial restrictions and complete restrictions. A
partial restriction allows some of the refrigerant to circulate through the
system. With a complete restriction there is no circulation of refrigerant in
the system. Restricted refrigerant systems display the same symptoms as a
“low-charge condition.” A quick check for either condition begins at the
evaporator. With a partial restriction, there may be gurgling sounds at the
metering device entrance to the evaporator. The evaporator in a partial
restriction could be partially frosted or have an ice ball close to the
entrance of the metering device. Frost may continue on the suction line back
to the compressor. Often a partial restriction of any type can be found by
feel, as there is a temperature difference from one side of the restriction to
the other. There will usually be a difference felt at the capillary tube. This
does not indicate a restricted condition. With a complete restriction, there
will be no sound at the metering device entrance. An amperage check of the
compressor with a partial restriction may show normal current when compared to
the unit specification. With a complete restriction the current drawn may be
considerably less than normal, as the compressor is running in a deep vacuum
(no load.) Much of the area of the condenser will be relatively cool since
most or all of the liquid refrigerant will be stored there. Make all checks
possible before tapping into the system and installing gauges. When the unit
is shut off, or the compressor disengages, the gauges may equalize very
slowly. The following conditions are based primarily on a system in the
cooling mode.

BURN HAZARD Proper safety procedures must be followed, and proper protective
clothing must be worn when working with a torch.
Failure to follow these procedures could result in moderate or serious injury.
WARNING
CUT/SEVER HAZARD Be careful with the sharp edges and corners. Wear protective
clothing and gloves, etc.
Failure to do so could result in serious injury.
Test the Capillary Tube and Check Valve Assy 1. Check the capillary tube temperature by hand where the refrigerant enters the capillary tube. A partial restriction of the capillary tube will be indicated by frost or freezing in that area. 2. If the capillary tube is fully restricted, then pressure will increase and pressure switch will open if installed. If no pressure switch is installed, the unit will shut down due to the compressor overload opening. High discharge temperature will be present at the compressor.

Failure to follow these procedures could result in moderate or serious injury.
Single Phase Running and L.R.A. Test NOTE: The L.R.A. can be found on the
rating plate. Select the proper amperage scale and clamp the meter probe
around the wire to the “C” terminal of the compressor. Turn on the unit and
read the running amperage on the meter. If the compressor does not start, the
reading will indicate the locked rotor amperage (L.R.A.).
Overloads The compressor is equipped with either an external or internal
overload which senses both motor amperage and winding temperature. High motor
temperature or amperage heats the overload causing it to open, breaking the
common circuit within the compressor. Heat generated within the compressor
shell, usually due to recycling of the motor, is slow to dissipate. It may
take anywhere from a few minutes to several hours for the overload to reset.
Checking the Overloads
CAUTION: Before attempting to check overloads, ensure that compressor is cool
to touch.
External Overloads With power off, remove the leads from compressor terminals.
If the compressor is hot, allow the overload to cool before starting check.
Using an ohmmeter, test continuity across the terminals of the external
overload. If you do not have continuity; this indicates that the overload is
open and must be replaced.
Internal Overloads Some model compressors are equipped with an internal
overload. The overload is embedded in the motor windings to sense the winding
temperature and/or current draw. The overload is connected in series with the
common motor terminal. Should the internal temperature and/or current draw
become excessive, the contacts in the overload will open, turning off the
compressor. The overload will automatically reset, but may require several
hours before the heat is dissipated.
Checking the Internal Overload 1. With no power to unit, remove the leads from
the compressor terminals. 2. Using an ohmmeter, test continuity between
terminals C-S and C-R. If no continuity, and the compressor is not hot to the
touch, the compressor overload is open, and the compressor should be replaced.

WARNING
ELECTRIC SHOCK HAZARD Turn off electric power before service or installation.
Extreme care must be used, if it becomes necessary to work on equipment with

Failure to do so could result in serious injury or death.
WARNING
HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil
under high pressure.
Proper safety procedures must be followed, and proper protective clothing must
be worn when working with refrigerants.
Failure to follow these procedures could result in serious injury or death.
Single Phase Resistance Test Remove the leads from the compressor terminals and set the ohmmeter on the lowest scale (R x 1). Touch the leads of the ohmmeter from terminals common to start (“C” to “S”). Next, touch the leads of the ohmmeter from terminals common to run (“C” to “R”). Add values “C” to “S” and “C” to “R” together and check resistance from start to run terminals (“S” to “R”). Resistance “S” to “R” should equal the total of “C” to “S” and “C” to “R.” In a single phase PSC compressor motor, the highest value will be from the start to the run connections (“S” to “R”). The next highest resistance is from the start to the common connections (“S” to “C”). The lowest resistance is from the run to common. (“C” to “R”) Before replacing a compressor, check to be sure it is defective.
GROUND TEST Use an ohmmeter set on its highest scale. Touch one lead to the
compressor body (clean point of contact as a good connection is a must) and
the other probe in turn to each compressor terminal. If a reading is obtained
the compressor is grounded and must be replaced. Check the complete electrical
system to the compressor and compressor internal electrical system, check to
be certain that compressor is not out on internal overload. Complete
evaluation of the system must be made whenever you suspect the compressor is
defective. If the compressor has been operating for sometime, a careful
examination must be made to determine why the compressor failed.
Many compressor failures are caused by the following conditions: 1. Improper
air flow over the evaporator. 2. Overcharged refrigerant system causing liquid
to be returned to the compressor. 3. Restricted refrigerant system. 4. Lack of
lubrication. 5. Liquid refrigerant returning to compressor causing oil to be
washed out of bearings. 6. Non-condensables such as air and moisture in the
system. Moisture is extremely destructive to a refrigerant system. 7.

Warning: Work shall be undertaken under a controlled procedure so as to
minimise the risk of a flammable gas or vapor being present while
the work is being performed. Check 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 toxic
or flammable atmospheres. · Ensure that the leak detection equipment being
used is suitable for use with all applicable refrigerants, i.e. non-sparking,
adequately sealed or
intrinsically safe. · 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 all refrigerant systems:
1. 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. (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. 2. 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. If a leak is suspected, all
flame sources shall be removed/extinguished. If a leakage of refrigerant is
found which requires brazing, all of the refrigerant shall be recovered from
the system per EPA guidelines. Presence of fire extinguisher: If any hot work
is to be conducted on the refrigerating equipment or any associated parts, a
class ABC Rated fire extinguishing equipment shall be available to hand. Have
a class ABC Rated fire extinguisher adjacent to the charging area.

R-32 SEALED SYSTEM REPAIR
General Information
Warning:
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.
Ventilated Area: Ensure that the area is in the open or that it is adequately
ventilated before accessing the refrigerant in 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 away from the work area or external to building envelope.
During Repairs To Sealed Components: All power must be removed from the
equipment being worked on prior to any removal of sealed covers, etc. If it is
absolutely necessary to have an electrical supply to equipment during
servicing, then a constant leak detector shall be located at the most critical
point to warn of a potentially hazardous situation.
Checks And Repairs 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 remove
power supply to unit. DO NOT OPERATE. · Initial safety checks shall include:
·That capacitors are discharged: this shall be done in a safe manner to avoid
possibility of sparking; ·That no live electrical components and wiring are
exposed while charging, recovering or purging the system; ·Verify unit is
properly grounded. · Particular attention shall be paid to the following to
ensure that by working on electrical components, the casing is not altered in
such a way that the level of protection is affected. This shall include damage
to cables, excessive number of connections, terminals not made to original
specification, damage to seals, incorrect fitting of glands, etc. · Ensure
that the apparatus is mounted securely. · Ensure that seals or sealing
materials have not degraded to the point that they no longer serve the purpose
of preventing the ingress of flammable atmospheres. Replacement parts shall be
in accordance with the manufacturer’s specifications. · The following is a
list of important considerations when working with R-32 equipment: · R-32
pressure is similar to R-410A and approximately 60% higher than R-22 pressure.
· R-32 cylinders must not be allowed to exceed 125°F, they may leak or
rupture. · R-32 must never be pressurized with a mixture of compressed air, it
may become MORE flammable. · Servicing equipment and components must be
specifically designed for use with R-32 and dedicated to prevent
contamination. · Manifold sets must be equipped with gauges capable of reading
750 psig (high side) and 200 psig (low side), with a 500-psig low-side retard.
· Gauge hoses must have a minimum 750-psig service pressure rating. · Recovery
cylinders must have a minimum service pressure rating of 400 psig, (DOT 4BA400
and DOT BW400 approved cylinders). · POE (Polyol-Ester) lubricants must be
used with R-32 equipment. · To prevent moisture absorption and lubricant
contamination, do not leave the refrigeration system open to the atmosphere
for extended periods of time. · If unit refrigerant is low, recover the
refrigerant, evacuate, and recharge unit to nameplate amount. · If there is
any amount of refrigerant in the system charge from the low side. · Always
charge by liquid inverted.
Verify with tool manufacturers that all tools used during this repair are non-
sparking and can be used with A2L Refrigerants. No halide torches for leak
testing. Refrigerant monitors or detectors must be used to detect refrigerant
in the work area.
· R-32 A2L Refrigerant Recovery System. · Vacuum Pump rated for A2L
refrigerant (capable of 300 microns or less vacuum.) · Nitrogen bottle with
purging and pressurizing capabilities up to 550 psi. · Oxy/ Acetylene torch or

Refrigerant Removal, Recovery, and Evacuation
NOTE: When accessing the refrigerant in the system to make repairs or for any
other purpose, conventional procedures shall be used. However, for FLAMMABLE
REFRIGERANTS (R-32 is classified in the A2L group for mildly flammable
refrigerants) it is important that best practice is followed since
flammability is a consideration. Follow all EPA 608 regulations and procedures
along with AHRI 15 Best Practices for A2L refrigerants.
Warning: Ensure sufficient ventilation at the repair place. Warning: Ensure
there are no open flame sources or hot surfaces that exceed 1200°F in the work
area. Warning: Discharge capacitors in a way that won’t cause any spark. The
standard procedure to short circuit the capacitor terminals usually
creates sparks.
NOTICE: Ensure that the following precautions are taken prior to opening the
sealed system.
· Verify Recovery machine is rated for A2L refrigerants. · Mark the Job site
inspection area as flammable work zone using appropriate signs. · Utilize a
Refrigerant leak detector or refrigerant monitor to sense the area for the
presence of refrigerants. · Disconnect all power supply to unit. · Properly
ground all equipment and hoses along with tank to prevent a static build up .
· Ensure adequate ventilation is provided for the job site. · Do not mix A2L
refrigerant Gages and hoses with other refrigerants. · Keep exposure of
refrigerant to Air to as minimum as possible (creates a dangerous condition).
· Under no circumstances is the mixing of refrigerants in the recovery
cylinders allowed and should be strictly avoided at all times. Do not
introduce oxygen into any recovery cylinders. 1. Install a piercing valve to
recover refrigerant from the sealed system. (Piercing valve must be removed
from the system before recharging.) 2. Recover refrigerant to EPA sec. 608
standards. If a low charge is suspected weigh recovered refrigerant and
compare to unit nameplate. NOTE: DO NOT RECOVER TO A VACUUM PRIOR TO FLUSHING
WITH NITROGEN. STOP RECOVERY AT 0-5 PSI. 3. Flush refrigerant out of system
with a dry nitrogen purge, make sure you energize and de-energize all
reversing valves and solenoid valves to release any trapped refrigerant.(3-5
minutes). 4. Perform an evacuation to 29.9 in. hg. and break vacuum with Dry
Nitrogen. 5. Re-purge the unit for 3-5 mins or until the nitrogen flows out
both process tubes. 6. Re-evacuate unit to 29.9 in. hg. and break vacuum with
Dry Nitrogen. 8. Open the refrigerant circuit by cutting out components. 9.
