NOTES TO INSTALLER
This manual is to aid the qualified HVAC contractor in the installation of this Mini Split system.
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 utilizes the 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 work be sure that water,
dust, former refrigerant, or refrigeration lubricating oil does not enter into the new type refrigerant R410A air
conditioner 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. For connecting pipes use new and clean piping materials
with high pressure fittings made for R410A only. The best and recommended solution is not to 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.
Installers please pass this manual and warranty registration to end user. If technical assistance is required
during installation or start up, please call 215-750-9876 (M-F 8:00 am to 4:30 pm ET) to speak to a Technical
Service Engineer. Before calling please have the Model and Serial numbers available.
