If the actual pressure is 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.
NOTICE
PUMP DOWN
This is performed when the unit is relocated or the refrigerant circuit is serviced.
Pump Down means collecting all refrigerant into the outdoor unit without the loss of refrigerant.
Be sure to perform Pump Down procedure in the 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 in the manifold hose using the refrigerant.
3. Close the liquid side service valve(all the way).
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
2
G(14.2 to 7.1 P.S.I.G.), fully close the gas side
valve and then quickly turn off the unit. Now Pump Down procedure is completed, and all refrigerant is
collected into the outdoor unit.
Settlement of outdoor unit
1. Fix the outdoor unit with a bolt and nut(ø10mm)
tightly and horizontally on a concrete or rigid mount.
2. 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.
3. If the vibration of the unit is transmitted to the pipe,
secure the unit with an anti-vibration rubber.
Evaluation of the performance
Operate the unit for 15~20 minutes, then check the
system refrigerant charge:
1. Measure the pressure of the gas side service valve.
2. Measure the air temperature from inlet and outlet of
air conditiioner.
3. Ensure the difference between the inlet and outlet
temperature is more than 8°C(46.4°F).
4. For reference; the gas side pressure at optimum
condition is shown on table (cooling)
The air conditioner is now ready to use.
