Test Running

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.

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.

NOTICE :

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.
