Safety Cautions Carefully read the following information in order to operate the airconditioner correctly. Below are listed three kinds of Safety Cautions and Suggestions. Incorrect operations may result in severe consequences of death or serious injuries. WARNING! CAUTION! Incorrect operations may result in injuries or machine damages; in some cases may cause serious consequences.
Safety Cautions Installed electrical-leaking circuit breaker. It easily cause electrical shock without circuit breaker. Air-conditioner can't be installed in the environment with inflammable gases because the inflammable gases near to air-conditioner may cause fire hazard. Please let the dealer be responsible for installing the conditioner.

M o d e l AU142AFBEA AU182AFBEA AU242AHBEA AU282AHBEA AU28NAHBEA AU36NAIBEA AU42NAIBEA AU52NAIBEA Precautions for refrigerant piping Do not twist or crush piping. Be sure that no dust is mixed in piping.
Installation Procedure 5. Air discharging method After finishing connection of refrigerant pipe, it shall perform air tightness test. The air tightness test adopts nitrogen tank to give pressure according to the pipe connection mode as the following figure shown. The gas and liquid valve are all in close state. In order to prevent the nitrogen entering the circulation system of outdoor unit, tighten the valve rod before giving pressure (both gas and liquid valve rods).
If the connecting pipe (L) exceeds 5m, it shall charge Mg additional refrigerant per meter. That is: Refrigerant charging amount = (L-5) x M (g) For AU142AFBEA, AU182AFBEA, M=30 For AU242AHBEA, AU282AHBEA, AU28NAHBEA, AU36NAIBEA, AU42NAIBEA, AU52NAIBEA Only in COOLING operation can charge the additional refrigerant.
Make wiring to supply power to the outdoor unit, so that the power for the indoor unit is supplied by terminals. For the detailed wiring connection with the indoor units, see the corresponding indoor operation and instruction manual. For: AU142AFBEA, AU182AFBEA WARNING Circuit breaker Switch breaker...
