FINAL INSTALLATION CHECKS

Check and Test Operation

For R410A, use the leak detector exclusively manufactured for HFC refrigerant (R410A, R134a, etc.).
*
The conventional leak detector for HCFC refrigerant (R22, etc.) cannot be used because its sensitivity for HFC
refrigerant lowers to approx. 1/40.
• Pressure of R410A is approx. 1.6 times higher than that of R22.
If installation work is incompletely finished, a gas leakage may occur when pressure rises during operation.
Therefore, be sure to test the piping connections for leakage.
• Check gas leakage at the flare nut connections, valve stem cap connections and service port cap fittings with a
leak detector or soap water.
When the remote controller is used for the first time, it accepts an operation approx. 5 minutes after the power
supply has been turned on.
It is not a trouble, but is because the setup of the remote controller is being checked.
For the second power-ON time and after, approx. 1 munute is required to start the operation by the remote controller.

Useful Functions

In addition to the code checking by remote controller of the indoor unit, troubles of the outdoor unit can be diag-
nosed by LED indications on the cycle control P .C. board of the outdoor unit. Utilize them for various checks.
For the check by remote controller of the indoor unit, refer to the Installation Manual of the indoor unit.
Before a check, confirm each bit of the DIP switch SW800 is set to OFF position.
