1. Check that all tubing and wiring have been

properly connected.

2. Check that the gas and liquid side service valves

are fully open.

Prepare remote control

Remove the battery cover

by pulling it according to the

arrow direction.

Insert new batteries making

sure that the (+) and (–) of

battery are installed correctly.

Reattach the cover by

pushing it back into position.

NOTE:

• Use 2 AAA(1.5volt) batteries. Do not use

rechargeable batteries.

• Remove the batteries from the remote control if

the system is not going to be used for a long

time.

Settlement of outdoor unit

Anchor the outdoor unit with a bolt and nut(ø10mm)

tightly and horizontally on a concrete or rigid mount.

When installing on the wall, roof or rooftop, anchor

the mounting base securely with a nail or wire

assuming the influence of wind and earthquake.

In the case when the vibration of the unit is

conveyed to the hose, secure the unit with an

anti-vibration rubber.

Bolt

Evaluation of the performance

Operate unit for 15~20 minutes, then check the

system refrigerant charge:

1. Measure the pressure of the gas side service

valve.

2. Measure the temperature of the intake and

discharge of air.

TEST RUNNING

Tubing connection

3. Ensure the difference between the intake

temperature and the discharge is more than 8°C

(Cooling) or reversely (Heating).

Discharge air

4. For reference; the gas side pressure of optimum

condition is as below. (Cooling)

Outside ambient TEMP. The pressure of the gas side service valve

35°C(95°F)

4.5~5.5kg/cm

NOTE: If the actual pressure are higher than shown, the

system is most likely over-charged, and charge

should be removed. If the actual pressure are

lower than shown, the system is most likely

undercharged, and charge should be added.

The air conditioner is now ready for use.

PUMP DOWN

This is performed when the unit is to be

relocated or the refrigerant circuit is serviced.

Pump Down means collecting all refrigerant in the

outdoor unit without loss in refrigerant gas.

CAUTION:

Be sure to perform Pump Down procedure with the

unit cooling mode.

Pump Down Procedure

1. Connect a low-pressure gauge manifold hose to the

charge port on the gas side service valve.

2. Open the gas side service valve halfway and purge

the air from the manifold hose using the refrigerant

gas.

3. Close the liquid side service valve(all the way in).

4. Turn on the unit's operating switch and start the

cooling operation.

5. When the low-pressure gauge reading becomes 1

to 0.5kg/cm

G(14.2 to 7.1 P.S.I.G.), fully close the

gas side valve stem and then quickly turn off the

unit. At that time, Pump Down has been completed

and all refrigerant gas will have been collected in

the outdoor unit.
