Installation Manual 27
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.
:
• 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 all indoor units for 15~20 minutes, then
check the system refrigerant charge:
1.Measure the pressure of one of the gas side
service valves.
2. Measure the temperature of the intake and
discharge of air.
3. Ensure the difference between the intake air
temperature and the discharge air is more
than 8°C(14.4°F).
4. For reference, optimum gas pressure for
cooling is shown below.
:
If the actual pressure is higher than
shown, the system is most likely over-charged, and
charge should be removed. If the actual pressure is
lower than shown, the system is most likely
undercharged, and charge should be added.
