Report all shipping damage to the carrier IMMEDIATELY. Check units and box exterior for damage.
Please read and understand these instructions prior to installing the unit, failure to comply with these
instructions may result in improper installation, operation and maintenance, possibly resulting in fire, electrical
shock, property damage, personal injury or death.
CAUTION! Do not use old refrigerant lines with new installation:
For connecting pipes use new and clean piping materials with high pressure fittings made for R410A only. This
air conditioner adopts the new HFC refrigerant (R410A) which does not destroy ozone layer. R410A refrigerant
operates at approximately 1.6 times the pressure of refrigerant R22. Accompanied with the adoption of the new
refrigerant, the refrigeration lubricating oil has also been changed. During installation be sure that water, dust or
foreign material does not enter into the new system. The system must not be left open to the atmosphere for
any reason for any period of time as the systems oil quickly absorbs moisture and will contaminate and damage
the system. To prevent mixing of refrigerant or refrigeration lubricating oil, the sizes of connecting sections of
charging port on main unit and installation tools are different from those used for the conventional refrigerant
units. Accordingly, special tools are required for the new refrigerant (R410A) units. The best and recommended
solution is - do not use the existing line sets because there may be some problems with pressure fittings and
possible impurities in the existing piping.
When installing this unit, an electrical surge suppressor is recommended.
