WARNING

Improper installation, adjustment, alteration, service

or maintenance can cause property damage, personal

injury or loss of life. Installation and service must be

performed by a licensed professional HVAC installer or

equivalent, service agency, or the gas supplier.

IMPORTANT

The Clean Air Act of 1990 bans the intentional venting of

refrigerant (CFCs, HCFCs and HFCs) as of July 1, 1992.

Approved methods of recovery, recycling or reclaiming

must be followed. Fines and/or incarceration may be

levied for noncompliance.

CAUTION

As with any mechanical equipment, contact with sharp

sheet metal edges can result in personal injury. Take

care while handling this equipment and wear gloves and

protective clothing.

WARNING

Electric Shock Hazard. Can cause injury or

death. Unit must be properly grounded in

accordance with national and local codes.

Line voltage is present at all components when

unit is not in operation on units with single-

pole contactors. Disconnect all remote electric

power supplies before opening access panel.

Unit may have multiple power supplies.

LRP14HP/LRP14AC/LRP14GE/LRP14GN/LRP16GE/LRP16HP SERIES UNITS

The LRP14/16 series packaged units are available in siz-

es ranging from 2 through 5 tons (7.0 through 17.6 kW).

The LRP14/16 unit is designed for HFC-410A refrigerant

and for outdoor residential use only. Units can be installed

at ground level or on rooftops. The LRP14 units utilize a

scroll compressor. LRP16GE/GX/HP units utilize a two-

stage compressor. Information contained in this manual is

intended for use by qualied service technicians only. All

specications are subject to change. Procedures outlined

in this manual are presented as a recommendation only

and do not supersede or replace local or state codes.
