Noise pollution
• Install the air conditioner at a place that can bear
its weight in order to operate more quietly.
15
• Install the outdoor unit at a place where the air
discharged and the operation noise would not
annoy your neighbours.
• Do not place any obstacles in front of the air
outlet of the outdoor unit lest it increases the
noise level.
Features of HEATING mode
Preheating
2-5 minutes are necessary to preheat the indoor
unit at HEATING operation start.
Defrosting (out door unit)
In HEATING operation the appliance will defrost
(de-ice) automatically to raise efficiency.
This procedure usually lasts 2-10 minutes. During
defrosting, fan stops operation.
After defrosting completes, it returns to
HEATING mode automatically.
Note: Heating is NOT available for cooling only
air conditioner models.
Features of protection device
1. Protection device
Wait at least 3 minutes before restarting the unit
after operation stops or changing mode during
operation.
After connecting to power supply and turning on
the appliance immediately, a delay of 20 seconds
may occur before it starts to operate.
2. If all operation has stopped, press ON/OFF
button again to restart. Timer should be set
again if it has been cancelled.
TROUBLESHOOTING
Operation problems are often due to minor causes that can be found and fixed without
using any tools:
Trouble
Analysis
Does not run
• Is the protection device or fuse blown?
• Please wait for 3 minutes and start again, protection device may be preventing
unit to work.
• Are the RC batteries low?
• Is the plug not properly plugged?
No cooling or
heating air
• Is the air filter dirty?
• Are the intakes and outlets of the air conditioner blocked?
• Is the temperature set properly?
Ineffective control
• Has there been a strong interference (from excessive static electricity discharge,
power supply voltage abnormality)? Note that operation will be abnormal, in this
case unplug from the power supply and re-plug after 2-3 seconds.
Does not operate
immediately
• 3 minute delay will occur when changing mode during operation.
Peculiar smell
• This smell may come from another source such as furniture, cigarette etc, which
is sucked in the unit and blown out with the air.
A sound of running
water
• Normal behaviour caused by the flow of refrigerant in the air conditioner.
• Defrosting sound in heating mode.
Cracking sound
• The sound may be generated by the expansion or contraction of the front panel
due to temperature changes.
Mist sprays from
the outlet
• Mist is present in the room with low temperature? Normal behaviour due to
cool air discharged from indoor unit during COOLING or DRY operation
mode.

OUTDOOR UNIT INSTALLATION
1. Install Drain Port and Drain Hose (for heatpump model only)
The condensate drains from the outdoor unit when
the unit operates in heating mode. In order not to
disturb your neighbours and protect the
environment, install a drain port and a drain hose to
direct the condensate water. Just install the drain
port and rubber washer on the chassis of the
outdoor unit, then connect a drain hose to the port
Washer
as shown in the figure on the right .
Drain port
2. Install and Fix Outdoor Unit
Drain hose
Fix with bolts and nuts tightly on a flat and strong
(prepare by user)
floor.
If installed on the wall or roof, make sure to fix the
supporter well to prevent it from shaking due to serious vibration or strong wind.
3. Outdoor Unit Piping Connection
• Remove the valve caps from the 2-way and 3-way valve.
• Connect the pipes to the 2-way and 3-way valves separately according to the required torque.
4. Outdoor Unit Cable Connection (see previous page)
Air purging
Air containing moisture remaining in the refrigeration cycle may cause a malfunction on the compressor.
After connecting the indoor and outdoor units, evacuate air and moisture from refrigerant cycle using a
vacuum pump, as shown below.
Note: Because the system pressure is high and also to protect the environment, be sure not to discharge
the refrigerant to the air directly.

How to Purge Air Tubes:
(1). Unscrew and remove caps from 2 and 3-way valves.
(2). Unscrew and remove cap from service valve.
(3). Connect vacuum pump flexible hose to the service valve.
(4). Start vacuum pump for 10-15 minutes until it reaches an absolute vacuum of 10 mm Hg.
(5). With vacuum pump still running close the low pressure knob on vacuum pump manifold. Then stop
vacuum pump.
(6). Open 2-way valve 1/4 turn, then close it after 10 seconds. Check tightness of all joints using liquid
soap or an electronic leak detector.
(7). Turn 2 and 3-way valves stem. Disconnect vacuum pump flexible hose.
(8). Replace and tighten all valve caps.
NOTES:
• Please read this manual carefully before installing and using the appliance.
• Do not let air enter the refrigeration system or discharge refrigerant when moving the air conditioner.
• Earth the air conditioner properly.
• Check the connecting cables and pipes carefully, make sure they are correct and firm before connecting
the power of the air conditioner.
• There must be an air-break switch.
• After installing, the consumer must operate the air conditioner correctly according to this manual, keep
a suitable storage for maintenance and move of the air conditioner in the future.
• Type of fuse used on indoor unit controller is Φ 5x20, with rating 2.5A/250V or 3.15A/250V.
• Caution: Mount with the lowest moving parts of indoor unit at Least 2.4m above floor or grade Level.
• Risk of electric shock can cause injury or death: Disconnect all Remote electric power supplies before
servicing.
• When charging refrigerant into the system, make sure to change in liquid state, if refrigerant of the
appliance is R410a. Otherwise, chemical composition of refrigerant (R410a) inside the system may
change and thus affect performance of the air conditioner.
• According to the character of refrigerant (R410a), the pressure of the tube is very high, so be sure to
careful when you install and repair the appliance.
• If the supply cord is damaged, it must be replaced by the manufacturers After-Sales Service
or a qualified technician in order to avoid a hazard.
• The air conditioner must be installed by professional engineer.
