And Major
Functions
Features
Protection of the air conditioner
Compressor protection
•The compressor cannot restart for 3 minutes
after it stops.
Anti-cold air (Cooling and heating models
only)
•The unit is designed not to blow cold air on
HEAT mode, when the indoor heat exchanger
is in one of the following three situations and
the set temperature has not been reached.
A) When heating has just started.
B) During defrosting.
C) Low temperature heating.
•The indoor or outdoor fan stop running when
defrosting (Cooling and heating models only).
Defrosting (Cooling and heating models only)
•Frost may be generated on the outdoor unit
during a heat cycle when outdoor temperature
is low and humidity is high resulting in lower
heating efficiency in the air conditioner.
•Under these conditions, the air conditioner will
stop heating operations and start defrosting
automatically.
•The time to defrost may vary from 4 to 10
minutes, depending the outdoor temperature
and the amount of frost buildup on the
outdoor unit.
Auto-Restart (some models)
In case of power failure, the system will
immediately stop. When power returns, the
Operation light on the indoor unit will flash. To
restart the unit, press the ON/OFF button on the
remote control. If the system has an auto restart
function, the unit will restart using the same
settings.
White mist emerging from the indoor unit
•A white mist may be generated due to a large
temperature difference between air inlet and
air outlet on COOL mode in places with high
relative humidity.
•A white mist may be generated due to moisture
created in the defrosting process when the air
conditioner restarts in HEAT mode operation
after defrosting.
Noise coming from the air conditioner
•You may hear a low hissing sound when the
compressor is running or has just stopped
running. This sound is the sound of the
refrigerant flowing or coming to a stop.
•You may also hear a low "squeaking" sound
when the compressor is running or has just
stopped running. This is caused by tempera
heat expansion and cold contraction of the
plastic parts in the unit when the temperature
is changing.
•A noise may be heard due to the louver
restoring itself to its original position when
power is first turned on.
Dust blowing out from the indoor unit.
This is happens when the air conditioner has not
been used for a long time or during its first use.
Smell emitting from the indoor unit.
This is caused by the indoor unit giving off smells
permeated from building materials, furniture,or
smoke.
Page 10
Unit Parts
And Major
Functions
The air conditioner turns to FAN ONLY
mode from COOL or HEAT (for cooling
and heating models only) mode.
When the indoor temperature reaches the set
temperature setting, the compressor will stop
automatically, and the air conditioner turns to
FAN only mode. The compressor will start again
when the indoor temperature rises on COOL
mode or falls on HEAT mode to the set point.
Droplets of water may form on the surface of
the indoor unit when cooling occurs in relatively
high humidity (defined as higher than 80%).
Adjust the horizontal louver to the maximum air
outlet position and select HIGH fan speed.
Heating mode (For cooling and heating
models only)
The air conditioner draws in heat from the
outdoor unit and releases it via the indoor unit
during heating. When the outdoor temperature
falls, heat drawn in by the air conditioner
decreases accordingly. At the same time, heat
loading of the air conditioner increases due to
larger difference between indoor and outdoor
temperature. If a comfortable temperature
cannot be achieved with the air conditioner
alone, it is recommended that you use a
supplementary heating device.
Lightning or a car wireless telephone operating
nearby may cause the unit to malfunction.
Disconnect the unit from its power source and
then re-connect the unit with the power source
again. Push the ON/OFF button on the remote
controller to restart operations.
Energy Saving Tips
•DO NOT
set the unit to excessive temperature levels.
•While cooling, close the curtains to avoid direct sunlight.
•Doors and windows should be kept closed to keep cool or warm air in the room.
•
DO NOT
place objects near the air inlet and outlet of the unit. This will reduce the efficiency of the unit.
•Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.
•If you don’t plan to use the unit for a long time, remove the batteries from the remote control.
•Clean the air filter every two weeks. A dirty filter can reduce cooling or heating efficiency.
•Adjust louvers properly and avoid direct airflow.
Closing curtains during heating also
helps keep the heat in
Doors and windows should be
kept closed

Manual Operations
And Maintenance
Manual Operations And Maintenance
Operation mode selection
Maintenance
While two or more indoor units are
simultaneously operating, make sure the modes
do not conflict with each other. The heat mode
claims precedence over all other modes. If the
unit intially started to operate in HEAT mode, the
other units can operate in HEAT mode only. For
example: If the unit intially started operates under
COOL (or FAN) mode, the other units can operate
under any mode except HEAT. If one of the unit
selects HEAT mode, the other operating units will
stop operation and diplay ”--” (for units with
display window only) or the auto and operation
indication light will flash rapidly, the defrost
indication light will turn off, and the timer
indication light will remain on (for units without
a display window). Alternatively, the defrost and
alarm indication light (if applicable) wil light up,
or the operation indication light will flash rapidly,
and the timer indication light will turn off ( for
the floor and standing type).
If you plan to leave the unit idle for a long time,
perform the following tasks:
1. Clean the indoor unit and air filter.
2. Select FAN ONLY mode and let the indoor fan
run for a time to dry the inside of the unit.
3. Disconnect the power supply and remove the
battery from the remote control.
4. Check components of the outdoor unit
periodically. Contact a local dealer or a
customer service centre if the unit requires
servicing.
When the air conditioner is to be used
again:
•Use a dry cloth to wipe off the dust
accumulated on the rear air intake grille in
order to avoid the dust being dispersed from
the indoor unit.
•Check that the wiring is not broken off or
disconnected.
•Check that the air filter is installed.
•Check if the air outlet or inlet is blocked after
the air conditioner has not been used for a
long time.
Suggestion:
For units that feature an electric heater,
when the outside ambient temperature is
below 32°F (0°C), it is strongly recommended
that you to keep the machine plugged in so
as to guarantee smooth operation.
Optimal operation
To achieve optimal performance, please note the
following:
•Adjust the direction of the air flow so that it is
notblowing directly on people.
•Adjust the temperature to achieve the highest
possible level of comfort. Do not adjust the unit
to excessive temperature levels.
•Close doors and windows in COOL mode or
HEAT mode.
•Use the TIMER ON button on the remote
controller to select a time you want to start
your air conditioner.
•Do not place any object near the air inlet or air
outlet, as the efficiency of the air conditioner
may be reduced and the air conditioner may
stop running.
•Clean the air filter periodically, otherwise
cooling or heating per formance may be
reduced.
•Do not operate unit with horizontal louvre in
closed position.
NOTE: Before you clean the air conditioner, be
sure to switch off the unit and disconnect the
power supply plug.

Troubleshooting
Problem 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.
Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/
Defrost) indicators are lit up, the outdoor temperature is too cold and the unit’s
anti-cold wind is activated in order to defrost the unit.
In Cooling-only Models: If the “Fan Only” indicator is lit up, the outdoor
temperature is too cold and the unit’s anti-freeze protection is activated in
order to defrost the unit.
The unit changes
from COOL mode
to FAN mode
The unit changes its setting to prevent frost from forming on the unit. Once
the temperature increases, the unit will start operating again.
The set temperature has been reached, at which point the unit turns off the
compressor. The unit will resume 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 from the defrosting process.

Troubleshooting
Problem Possible Causes
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.
The indoor unit
makes noises
A squeaking sound is heard when the system is OFF or in COOL mode. The
noise is also heard when the drain pump (optional) is in operation.
A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Both the indoor
unit and outdoor
unit make noises
A low hissing sound may occur during operation. This is normal and is caused
by refrigerant gas flowing through both the indoor and outdoor units.
A low hissing sound may be heard 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.
The outdoor unit
makes noises
The unit will make different sounds based on its current operating mode.

Copper pipe
When connecting refrigerant piping, do not
let substances or gases other than the specified
refrigerant enter the unit. The presence of other
gases or substances will lower the unit’s capacity,
and can cause abnormally high pressure in the
refrigeration cycle. This can cause explosion and
injury.
Step 1: Cut pipes
When preparing refrigerant pipes, take extra
care to cut and flare them properly. This will
ensure efficient operation and minimize the
need for future maintenance.
1. Measure the distance between the indoor
and outdoor units.
CAUTION
•The branching pipe must be installed
horizontally. An angle of more than 10° may
cause malfunction.
•DO NOT install the connecting pipe until
both indoor and outdoor units have been
installed.
•Insulate both the gas and liquid piping to
prevent water leakage.
Connection Instructions –
Refrigerant Piping
2.
Using a pipe cutter, cut the pipe a little longer
than the measured distance.
3. Make sure that the pipe is cut at a perfect 90°
angle.
DO NOT DEFORM PIPE
WHILE CUTTING
Be extra careful not to damage, dent, or deform
the pipe while cutting. This will drastically reduce
the heating efficiency of the unit.
Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtight
seal.
1.
After removing burrs from cut pipe, seal
the ends with PVC tape to prevent foreign
materials from entering the pipe.
2.
Sheath the pipe with insulating material.
3.
Place flare nuts on both ends of pipe.
Make sure they are facing in the right
direction, because you can’t put them on
or change their direction after flaring.
Step 2: Remove burrs.
Burrs can affect the air-tight seal of refrigerant
piping connection. They must be completely
removed.
1.
Hold the pipe at a downward angle to
prevent burrs from falling into the pipe.
2.
Using a reamer or deburring tool, remove
all burrs from the cut section of the pipe.

Step 4: Connect pipes
Connect the copper pipes to the indoor unit first,
then connect it to the outdoor unit. You should
first connect the low-pressure pipe, then the
high-pressure pipe.
1. When connecting the flare nuts, apply a thin
coat of refrigeration oil to the flared ends of
the pipes.
2. Align the center of the two pipes that you will
connect.
Indoor unit tubing
Flare nut
Pipe
3. Tighten the flare nut as tightly as possible
by hand.
4. Using a spanner, grip the nut on the unit
tubing.
5. While firmly gripping the nut, use a torque
wrench to tighten the flare nut according to
the torque values in above table.
NOTE: Use both a spanner and a torque
wrench when connecting or disconnecting
pipes to/from the unit.
CAUTION
•
Ensure to wrap insulation around the piping.
Direct contact with the bare piping may
result in burns or frostbite.
•Make sure the pipe is properly connected.
Over tightening may damage the bell
mouth and under tightening may lead to
leakage.

6. After connecting the copper pipes to the
indoor unit, wrap the power cable, signal
cable and the piping together with binding
tape.
NOTE: DO NOT intertwine signal cable with
other wires. While bundling these items
together, do not intertwine or cross the signal
cable with any other wiring.
7. Thread this pipeline through the wall and
connect it to the outdoor unit.
8. Insulate all the piping, including the valves
of the outdoor unit.
9. Open the stop valves of the outdoor unit to
start the flow of the refrigerant between
the indoor and outdoor unit.
CAUTION
Check to make sure there is no refrigerant
leak after completing the installation work.

CAUTION
After confirmation of the above conditions, follow these guidelines when performing wiring:
•Always have an individual power circuit specifically for the air conditioner. Always follow
the circuit diagram posted on the inside of the control cover.
•
• Check the specifications for the power source.
•Confirm that electrical capacity is sufficient.
•Confirm that the cable thickness is as specified in the power source specifications.
•Always install an earth leakage circuit breaker in wet or moist areas.
Screws fastening the wiring in the casing of electrical fittings may come loose during
transporation. Because loose screws may cause wire burn-ou, check that the screws are
tightly fastened.
•The following can be caused by a drop in voltage: vibration of a magnetic switch,
damaging the contact point, broken fuses, and disturbance of normal functioning.
•Confirm that starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
•Before accessing terminals, all supply circuits must be disconnected.
•Disconnection from a power supply must be incorporated into the fixed wiring. It must
have an air gap contact separation of at least 3mm in each active (phase) conductors.
NOTE:
To satisfy the EMC compulsory regulations, which is required by the international standard
CISPR 14-1:2005/A2:2011 in specific countries or districts ,please make sure you apply the
correct magnetic rings on your equipment according to the wiring diagram that adhere to
the your equipment .

Before using a manifold gauge and a vacuum
pump, read their operation manuals to make
sure you know how to use them properly.

Fig. 9.1
Pressurize the system with 450-500 pounds
of nitrogen for at least 1 hour. If there is a
pressure drop find the leak and fix it. Repeat
this step until there are no leaks.
1. Using a valve core removal tool with a micron
gauge port attach it to the low side valve and
remove the valve core. Then attach your micron
gauge to the appropriate port.
2. Connect the manifolds low side hose (blue) to the
other end of the valve core removal tool
3. Open the Low Pressure side of the manifold gauge.
Keep the High Pressure side closed.
4. Turn on the vacuum pump to evacuate the system.
5. Run the vacuum pump until your Micron Gauge
reads 400 microns
6. Isolate the valve core removal tool and watch if the
pressure rises: if it rises over 500 microns keep
running the vacuum. The goal is to stabilize with
no rise in pressure and stay at 500 microns
7. After you have achieved a proper vacuum open
the valves on the condenser using a 5 mm allen
wrench turning them counter clockwise until it stops
8. Replace the schrader valve back into the low side
service port. You are now finished with a proper
vacuum and you can remove your hoses.
9. Tighten valve caps by hand, then tighten it
completely using an adjustable wrench.
OPEN VALVE STEMS GENTLY
When opening the valve stems, turn the hexagonal wrench
until it hits against the stopper. DO NOT
try to force the
valve to open further.
CAUTION
• Connect your vacuum gauge to the king
valves located on top
NOTE: IF THE KING VALVES ARE NOT
OPENED AFTER EVACUATION SERIOUS
DAMAGE CAN BE DONE
TO THE COMPRESSOR
• Open all of the valves that you have heads
connected to
• Use a vacuum pump and a Micron Gauge
to achieve a reading of no lower than 500
microns when completed
• The outdoor unit DOES NOT need to be
vacuumed. DO NOT open the outdoor units
liquid and gas king valves until after
evacuation is complete. These are the last
two valves to open and they will also
release the refrigerant into the condenser.
• Vacuum the system until you reach 500
microns, then isolate the micron gauge from
the vacuum and watch to see if the gauge
rises. Keep repeating the vacuum process
until the micron gauge does not exceed 500
microns when isolated.

Note On Adding Refrigerant
CAUTION
•Refrigerant charging must be performed after wiring, vacuuming, and the leak testing.
•DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system.
Doing so can damage the unit or impact it’s functioning.
•Charging with unsuitable substances may cause explosions or accidents. Ensure that the
appropriate refrigerant is used.
•For the R290 or R32 refrigerant model, make sure the condtions within the area have been
made safe by control of flammable material when the refrigerant added into air conditioner.
Refrigerant containers must be opened slowly. Always use protective gear when charging the
system.
•
• DO NOT mix refrigerants types.

Depending on the length of connective piping or the pressure of the evacuated system, you
made need to add refrigerant. Refer to table below for refrigerant amounts to be added:
Only for Australia models :
•
DO NOT
mix refrigerants types.
N=2(one-twin models),N=3(one-three models),N=4(one-four models),N=5(one-five models).
Some systems require additional charging depending on pipe lengths. The standard pipe length
is 10m. The additional refrigerant to be charged can be calculated using the following formula:
Make sure to remove the additional refrigerant charge according to the rated volume (5m
refrigerant piping) when doing market or government verification test.

Safety And Leakage Check
Electrical safety check
Perform the electrical safety check after
completing installation. Cover the following
areas:
1. Insulated resistance
The insulated resistance must be more
than 2MΩ.
2. Grounding work
After finishing grounding work, measure
the grounding resistance by visual detection
and using the grounding resistance tester.
Make sure the grounding resistance is less
than 4Ω.
3. Electrical leakage check (performing during
test while unit is on)
During a test operation after completed
installation, the use the electroprobe and
multimeter to perform an electrical leakage
check. Turn off the unit immediately if
leakage happens. Try and evaluate different
solutions until the unit operates properly.
Gas leak check
1. Soap water method:
Apply a soap-water solution or a liquid
neutral detergent on the indoor unit
connection or outdoor unit connections with
a soft brush to check for leakage of the
connecting points of the piping. If bubbles
emerge, the pipes are experiencing leakage.
2. Leak detector
Use the leak detector to check for leakage.
NOTE: The illustration is for example purposes
only. The actual order of A, B, C, D, and E on
the machine may be slightly different from the
