Settlement of outdoor unit

■ 

Anchor the outdoor unit with a bolt and
nut(ø10mm(0.39in) 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.

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

1. Remove the battery cover 

by pulling it according to the

arrow direction.

2. Insert new batteries making 

sure that the (+) and (–) of 
battery are installed correctly.

3. 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.

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.

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.

Bolt

Tubing connection

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 of refrigerant.

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 will have been collected in the
outdoor unit.

PUMP DOWN

3. Ensure the difference between the intake

temperature and the discharge is more than
46.4°F(8°C) (Cooling) or (Heating).

4. For reference; the gas side pressure of optimum

condition is as below.(Cooling)
