This air conditioner must be grounded without fail Grounding is necessary not only to safeguard against the possibility of receiving an electric shock but also to absorb both the static which is generated by high frequencies and held in the surface of the outdoor unit and noise since the air conditioner incorporates a frequency conversion device called an inverter in the outdoor unit If the air conditioner is not grounded users may receive an electric shock if they touch the surface of the outdoor unit and that unit is charged with static 10 7 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 of that manufactured exclusively for HFC refrigerant Pressure of R410A becomes approx 1 6 times that of R22 If installation work has not completely finished gas leaks may occur in cases such as when pressure rises during operation Check the flare nut connections valve stem cap connections and service port cap connections for gas leaks with a leak detector or soap water Flare nut connections Indoor unit Flare nut connections Outdoor unit Valve stem cap connection Service port cap connection CAUTION Use a circuit breaker of a type that is not tripped by shock waves Incorrect incompl
