1. Check that all tubing and wiring have been
properly connected.
2. Check that the gas and liquid side service
valves are fully open.
"1.Prepare remote control
ORemove 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.
NOT£:
• 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.
2. Settlement of outdoor unit
• Anchor the outdoor unit with a bolt and
nut(_10mm:0.39") 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.

3. 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.
3. Ensure the difference between the intake
temperature and the discharge is more than
8°C(46 F) (Cooling) or reversely (Heating).

PUMPDOWN
This is performed when the unit is to be
relocated or the refrigerant circuit is serviced.
Pump Down means collecting alt 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-pressuregauge 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 manifoldhose using the
refrigerant gas.
3. Close the liquidside service valve(all the way in).
4. Turn on the unit's operating switch and start the
cooling operation.
5. When the low-pressuregauge reading becomes
1 to 0.5kg/cm_G(14.2 to 7.1 PSI.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
collectedin the outdoor unit.
