TEST RUNNING

1.Check that all tubing and wiring have been properly connected.

2.Check that the gas and liquid side service valves are fully open.

APrepare 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.

BSettlement of outdoor unit

■Anchor the outdoor unit with a bolt and

nut(ø 10mm(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.

CEvaluation 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.

3.Ensure the difference between the intake temperature and the discharge is more than 8°C(46.4°F) (Cooling) or reversely (Heating).

35°C(95°F)

4~5kg/cm2 G(56.8~71.0 P.S.I.G.)

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/cm2 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.
