_ Installation Instructions
2. Safe Installation Requirements
Installation or repairs made by unqualified per-
sons can result in hazards to you and others.
Installation MUST conform with local building
codes or, in the absence of local codes, with the
National Electrical Code NFPA70-1990 or in Can-
ada the CSA C.22.1 - Canadian Electrical Code
Part 1.
The information contained in this manual is in-
tended for use by a qualified service technician
familiar with safety procedures and equipped
with the proper tools and test instruments.
Failure to carefully read and follow all instruc-
tions in this manual can result in furnace malfunc-
tion, property damage, personal injury and/or
death.
NOTE: It is the personal responsibility and obligation of the
customer to contact a qualified installer to ensure that the
installation is adequate and conforms to governing codes
and ordinances.
3. Locating the Unit

may be installed on a concrete mounting base at ground lev-
el, or on a rooftop with an adequate platform or if using as a
downflow model, with a roof curb.

Clearances
Combination Units I
Access Panels
The location MUST allow for minimum clearances and
should not be adjacent to a patio or other area where the
unit's operating sound level might be objectionable.
Clearances MUST be maintained from adjacent structures
to provide adequate fire protection and room for service per-
sonnel.
NOTE: Filter racks need a 26" minimum clearance at front of
unit for removal offilters. See chart below if unit isgoing to be
placed near combustible construction or materials.
While minimum clearances are acceptable for safety rea-
sons, they may not allow adequate air circulation around the
unit for proper operation in the cooling mode. Whenever
possible, it is desirable to allow additional clearance, espe-
cially around the condenser inlet and discharge openings.
Do NOT install the unit in a location that will permit dis-
charged air from the condenser to recirculate to the con-
denser inlet.
CAUTION
Do NOT operate unit in a corrosive atmosphere contain-
ing chlorine, fluorine, or any other corrosive chemicals.
