Common Issues
The following problems are not a malfunction and in most situations will not require repairs.

Issue Unit does not turn on when pressing ON/OFF button
The unit changes from COOL/HEAT mode to FAN mode
The indoor unit emits white mist Both the indoor and outdoor units emit white mist The indoor unit makes noises
Both the indoor unit and outdoor unit make noises

Possible Causes
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 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.
In humid regions, a large temperature difference between the room’s air and the conditioned air can cause white mist.
When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.
A rushing air sound may occur when the louver resets its position. 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.
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.

Page 14

Troubleshooting

Issue
The outdoor unit makes noises
Dust is emitted from either the indoor or outdoor unit

Possible Causes
The unit will make different sounds based on its current operating mode.
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.

NOTE ON DRAINPIPE INSTALLATION

· When using an extended drainpipe, tighten

the indoor connection with an additional

protection tube to prevent it from pulling

loose.

· The drainpipe should slope downward at a gradient of at least 1/100 to prevent water from flowing back into the air conditioner.

· To prevent the pipe from sagging, space hanging wires every 1-1.5m (39-59″).

· Incorrect installation could cause water to flow back into the unit and flood.

NOTE: When connecting multiple drainpipes, install the pipes as illustrated in the following Figure.

10cm (4″)
3. Pass the drain hose through the wall hole. Make sure the water drains to a safe location where it will not cause water damage or a slipping hazard.

Installation requires a polyethylene tube (exterior diameter = 3.7-3.9cm, interior diameter = 3.2cm), which can be obtained at your local hardware store or dealer.

NOTE: The drainpipe outlet should be at least 5cm (1.9″) above the ground. If it touches the ground, the unit may become blocked and malfunction. If you discharge the water directly into a sewer, make sure that the drain has a U or S pipe to catch odors that might otherwise come back into the house.

Air Evacuation

Preparations and Precautions
Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can damage the air conditioner, reduce its efficiency, and cause injury. Use a vacuum pump and manifold gauge to evacuate the refrigerant circuit, removing any non-condensable gas and moisture from the system.
Evacuation should be performed upon initial installation and when unit is relocated.
BEFORE PERFORMING EVACUATION
Check to make sure the connective pipes between the indoor and outdoor units are connected properly .
Check to make sure all wiring is connected properly.

8. If there is a change in system pressure, refer to Gas Leak Check section for information on how to check for leaks. If there is no change in system pressure, unscrew the cap
9. from the packed valve (high pressure valve). Insert hexagonal wrench into the packed valve (high pressure valve) and open the valve by turning the wrench in a 1/4 counterclockwise turn. Listen for gas to exit the system, then close the valve after 5 seconds.
10. Watch the Pressure Gauge for one minute to make sure that there is no change in pressure. The Pressure Gauge should read slightly higher than atmospheric pressure.
11. Remove the charge hose from the service port.

Evacuation Instructions

1. Connect the charge hose of the manifold gauge to service port on the outdoor unit’s low pressure valve.
2. Connect another charge hose from the manifold gauge to the vacuum pump.
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 for at least 15 minutes, or
until the Compound Meter reads -76cmHG
(-105Pa).

12. Using hexagonal wrench, fully open both the high pressure and low pressure valves.
13. Tighten valve caps on all three valves (service port, high pressure, low pressure) by hand. You may tighten it further using a torque wrench if needed.
OPEN VALVE STEMS GENTLY
When opening valve stems, turn the hexagonal wrench until it hits against the stopper. Do not try to force the valve to open further.

Low pressure valve
6. Close the Low Pressure side of the manifold gauge, and turn off the vacuum pump.
7. Wait for 5 minutes, then check that there has been no change in system pressure.

Note on Adding Refrigerant
Some systems require additional charging depending on pipe lengths. The standard pipe length varies according to local regulations. In other areas, the standard pipe length is 5m (16`). The refrigerant should be charged from the service port on the outdoor unit’s low pressure valve. The additional refrigerant to be charged can be calculated using the following formula:

R-32 :

Liquid Side Diameter

6.35(1/4″)

9.52(3/8″)

12.7(1/2″)

(Total pipe length standard pipe length)x 12g(0.13oZ)/m(ft)

(Total pipe length standard pipe length)x 24g(0.26oZ)/m(ft)

(Total pipe length standard pipe length)x 40g(0.42oZ)/m(ft)

CAUTION DO NOT mix refrigerant types.

Test Run

Before Test Run

A test run must be performed after the entire system has been completely installed. Confirm the following points before performing the test:
a) Indoor and outdoor units are properly installed.
b) Piping and wiring are properly connected. c) No obstacles near the inlet and outlet of
the unit that might cause poor performance or product malfunction. d) Refrigeration system does not leak. e) Drainage system is unimpeded and draining to a safe location. f) Heating insulation is properly installed. g) Grounding wires are properly connected. h) Length of the piping and additional refrigerant stow capacity have been recorded. i) Power voltage is the correct voltage for the air conditioner.
CAUTION
Failure to perform the test run may result in unit damage, property damage, or personal injury.
Test Run Instructions
1. Open both the liquid and gas stop valves. 2. Turn on the main power switch and allow the
unit to warm up. 3. Set the air conditioner to COOL mode. 4. For the Indoor Unit
a. Ensure the remote control and its buttons work properly.
b. Ensure the louvers move properly and can be changed using the remote control.
c. Double check to see if the room temperature is being registered correctly.
d. Ensure the indicators on the remote control and the display panel on the indoor unit work properly.
e. Ensure the manual buttons on the indoor unit works properly.

f. Check to see that the drainage system is unimpeded and draining smoothly.
g. Ensure there is no vibration or abnormal noise during operation.
5. For the Outdoor Unit
a. Check to see if the refrigeration system is leaking.
b. Make sure there is no vibration or abnormal noise during operation.
c. Ensure the wind, noise, and water generated by the unit do not disturb your neighbors or pose a safety hazard.
6. Drainage Test
a. Ensure the drainpipe flows smoothly. New buildings should perform this test before finishing the ceiling.
b. Remove the test cover. Add 2,000ml of water to the tank through the attached tube.
c. Turn on the main power switch and run the air conditioner in COOL mode.
d. Listen to the sound of the drain pump to see if it makes any unusual noises.
e. Check to see that the water is discharged. It may take up to one minute before the unit begins to drain depending on the drainpipe.
f. Make sure that there are no leaks in any of the piping.
g. Stop the air conditioner. Turn off the main power switch and reinstall the test cover.
NOTE: If the unit malfunctions or does not operate according to your expectations, please refer to the Troubleshooting section of the Owner’s Manual before calling customer service.
