It ONLY A QUALIFIED, EXPERIENCED causes capacity down, and risk of ELECTRICIAN SHOULD ATTEMPT TO explosion and injury due to high WIRE THIS SYSTEM.
Page 3 • Do not leak refrigerant while piping work for an installation or re-installation, and while repairing refrigeration parts. Handle liquid refrigerant carefully as it may cause frostbite. When Servicing • Turn the power OFF at the main power box (mains) before opening the unit to check or repair electrical parts and wiring.
Page 4: Check Of Density Limit
The refrigerant (R410A), which is used in the air conditioner, is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws imposed to protect the ozone layer.

In this way, the setting switches that were located on earlier PCBs have been converted to EEPROM data. This remote controller is an out- door unit maintenance tool that is used to make and change the EEPROM settings.
