Replace batteries with new ones of the same type when the display  
becomes dim.  
If the replacement is done within 1 minute, the remote controller  
will keep original presetting. However, if you want to change the  
presetting from Heat Pump to Cool Only or Cool Only to Heat Pump,  
you should reload batteries 3 minutes after removing the old ones.

view of a standard model. Consequently, the shape  
may differ from that of the air conditioner you have  
selected.  
Caution:  
1. Never fail to have an individual power circuit specifically for the air conditioner. As for the method of  
wiring, refer to the circuit diagram posted on the inside of the access door .  
2.Comfirm that the cable thickness is as specified in the power source specification.  
(See the cable specification table below)  
3.Check the wires and make sure that they are all tightly fastened after cable connection.  
4. Be sure to install an earth leakage circuit breaker in wet or moist area.

Attention:  
Accessibility to the plug must be guaranteed even after the installation of the appliance to disconnect  
it in case of need. If not possible, connect appliance to a double-pole switching device with contact  
separation of at least 3 mm placed in an accessible position even after installation.

Installation instructions  
Outdoor unit installation  
1.Install Drain Port and Drain Hose (for heat-pump model only)  
The condensate drains from the outdoor unit when the unit operates  
in heating mode. In order not to disturb your neighbor 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 to  
the chassis of the outdoor unit, then connect a drain hose to the  
port as the right figure shown.

2. Install and Fix Outdoor Unit  
Fix with bolts and nuts tightly on a flat and strong 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  
The air which contains 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: To protect the environment, be sure not to discharge the refrigerant to the air directly.  
See next page for air purging steps.

Installation instructions  
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 reaching a vacuum of 10 mm Hg absolutes.  
(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 to fully the valves. Disconnect vacuum pump flexible hose.  
(8). Replace and tighten all valve caps.  
Notes  
Please read this manual before installing and using it.  
Do not let air enter the refrigeration system or discharge refrigerant when moving the air conditioner.  
Testing run the air conditioner after finishing installation, and record details of operation.  
Type of fuse used on indoor unit controller is 50T, with rating 2.5A,AC250V.  
The fuse for the whole unit is to be provided by the user according to the current at maximum power  
Input or use other over-current protective device instead.  
Only the air conditioner can be connected to the power line.  
The power connection for the air conditioner has to be done at the main power distribution which has  
to be of a low impedance.  
In order to ensure the suitability of the equipment for connection, the user should consult with the  
supply authority, if necessary, that the service current capacity at the interface point is sufficient  
for the equipment.  
Refer to the rating plate of the equipment for power consumption details.  
If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or  
similarly qualified person in order to avoid a hazard.
