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.

Troubles of the outdoor unit can be diagnosed by LED indica-
tions 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 outdoor unit.
Before a check, confirm each bit of the DIP switch is set to OFF
position.
