ELECTRICAL WORK / INSTALLATION METHOD
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
N 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
N 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.

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

Drain Hose
N 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
N The piping of this unit can be connected to the left and rear side.
N 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 / AIR PURGE
AIR PURGE
N Be sure to perform the air purge of the indoor unit, and piping using the refrigerant of the outdoor unit at
the time of installation.
1. Connect the charging hose of low pressure side of
manifold gauge to the packed valve having a service
port (3/4" Packed valve) as shown at the figure.

3. Purge the air from the system using vacuum pump for
about 10 minutes.
- Close the valve of the low pressure side of manifold
gauge clockwise.
- Remove the hose of the low pressure side of manifold
gauge.
4. Set valve cork of both liquid side and gas side of
packed valve to the open position.
5. Mount the valve stem nuts to the 3-way valve.
• And mount the service port cap to 3-way valve.
6. Check for gas leakage.
• - At this time, especially check for gas leakage from
the 3-way valve’s stem nuts, and from the service
port cap.

REFRIGERANT CHARGING
Air purge(at the time of new installation only)
Close the gas pipe side valve by turning it
clockwise.
Connect the pressure gauge to the low
pressure side service valve, and then open
the gas pipe side valve again.
Connect it to the refrigerant filling tank.
(Turn the tank upside down : Fill the refrigerant
in liquid form.)
Start cooling operation.
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
N After checking, read the owner’s 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 owner’s 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)
