ELECTRICAL WORK  
The electrical work should be performed by a specialist qualified for the work.  
Use the three phase power supply, and be sure to install the sub power distributing board for  
exclusive use with the unit(separately purchased by the user).  
Avoid octopus-type wiring as it can cause a drop in voltage, thus resulting in poor performance  
of the automatic control circuit.  
Be sure to install circuit breaker (separately purchased by the user).  
Be sure to connect the grounding wire.

INSTALLATION METHOD  
Installation Procedures  
1. Open the inlet grille, and remove the flare nut.  
2. Bend the connection pipe to an appropriate length using the spring bender depending  
upon the installation place.  
- Allowable pipe length : Maximum 25m(82ft)  
- Allowable pipe drop distance : Maximum 15m(49ft)  
- Make no more than ten bending points on the pipe  
When the pipe length is in excess of the standard pipe length of 5m(16ft 5 in), add the refrigerant  
(R-22) of 50g(0.11lb) for each additional 1m(3.28ft).  
CAUTION  
If the pipe is lengthened, the performance of the unit is degraded, and the service life is shortened.  
Therefore, the pipe length should be as short as possible (less then 15m/49ft).

3. Install the high pressure pipe to the heat exchanger liquid pipe, and the low pressure pipe to the  
heat exchanger gas pipe respectively using the flare nut, taking care not to cause any leakage of refrigerant.  
4. Be sure to insulate the pipe with appropriate insulation material.  
5. Insert the drain hose into the drain pipe, and connect them by tying them to the cable tie to prevent  
any water leakage.  
6. After completion of the installation, check the connecting area for any gas leakage.  
7. Wind a finish tape when the wiring of the refrigerant pipe, the unit, and the drain piping are completed.

Pipe Bending  
1. Perform bending of the pipe using the bender which has a specified bending radius.  
Spring  
2. Be sure to take full care to perform bending of the pipe successfully at one time.  
Bending and unbending the pipe more than twice makes  
the bending work increasingly difficult.  
3. You may use the spring inserted into the gas pipe instead  
of the bender to bend the pipe.  
4. When you bend the pipe using the spring, hold the pipe with both hands to prevent  
any distortion, and secure a minimum bending radius of more than 100mm(4 inch).  
Tightening of Connection Parts  
Align the center of the connection piping, and tighten the flare nut by turning it with  
hand. Then tighten it again using the spanner in the direction as shown in the figure.

Drilling a Hole in the Wall  
Drill a hole of 70mm(3 inch) in diameter to the outside.  
The drilling should be done at a distance of less than  
150mm(6 inch) from the floor facing the indoor unit.

Drain Hose  
Extend the drain hose to the drain hose connected  
to the drain pan, and fix it with the tape or a cable tie  
to prevent separation. Then make a covering of it  
so that water can not flow outwardly.

CAUTION  
1. As the draining is of natural drain type, make the drain hose direct downward.  
2. If there is any foreign substance in the drain plate, it may clog the drain pipe.  
Therefore, be sure to remove the foreign substance inside after installation.  
3. After completion of installation, be sure to pour water into the drain pan,  
and then check the draining condition.  
(There is no problem in draining when the draining is completed within 20 seconds.)  
Rat-prevention Cover  
The piping of this unit can be connected to the left and rear side.  
When you hit the area for piping connection slightly with a hammer, a hole is made.  
- If there is any reason to change connection, fill in hole with rubber cabi slot.

INSTALLATION METHOD  
Indoor Unit  
In order to install drain hose through wall, adjust height (max. 150mm/5.91 inch) of the indoor unit using leg  
holder.  
Fixing to the floor  
When using the leg holder of the indoor unit.  
1. Lie down the unit on flat floor.  
Leg holder of  
the indoor unit  
2. Insert the leg holders into screwed holes  
and then fasten them clockwise.  
3. Turn the unit right and adjust horizontal line of it.  
Mis-alignment of the unit can cause vibration and noise.  
Fixing to the wall  
When using fixing holder of the indoor unit.  
1. Fix the holder using long screw bolts on wall.  
2. Fix the unit using two screw bolts or four anchor bolts.

Check the pressure of the pressure gauge.  
Check whether the low pressure side is within  
the range of 4.5~5.5kg/cm2G  
(outside temperature 35°C/95˚F).  
Open the tank and refill the refrigerant  
until arriving at the proper pressure.  
(Refill the refrigent slowly checking the pressure.)  
Stop operation.

CHECK AND TEST OPERATION  
Test Operation  
➧➧ After checking, read the owners instructions carefully, and perform a test operation.  
Then deliver the unit to the customer.  
(When delivering the unit, be sure to read carefully and follow the contents of the owners instructions.)  
CAUTION  
1. Be sure to check whether the service valve is opened before attempting to perform  
the test operation.  
2. Never attempt to start test operation by force pressing the electronic contactor as  
it is very dangerous.  
(This is very dangerous as the protective device does not work.)  
3. Be sure to perform the test operation after installation.  
It is easy to start the test operation in winter if you increase the sensor temperature to  
23°C(73.4˚F) ~ 25°C(77˚F) by holding the indoor temperature sensor. (Cooling operation)
