Location • Air filters must be replaced upon construction completion.
Use the following guidelines to select a suitable location
for the unit.
1. Unit is designed for outdoor installation only. Unit must
be installed so all electrical components are protected
from water.
2. Condenser coils must have an unlimited supply of air.
3. For ground level installation, use a level prefabricated
pad or use a level concrete slab. Do not tie the slab to
the building foundation.
4. Maintain level within a tolerance of 1/4" maximum
across the entire length or width of the unit.
5. Do not locate the unit where the combustion air supply
will be exposed to any of the following substances:
Permanent wave solutions
Chlorinated waxes and cleaners
Chlorine-based swimming pool chemicals
Water softening chemicals
Deicing salts or chemicals
Carbon tetrachloride
Halogen-type refrigerants
Cleaning solvents (such as perchloroethylene)
Printing inks, paint removers, varnishes, etc.
Cements and glues
Antistatic fabric softeners for clothes dryers
Masonry acid washing materials
Chlorinated laundry products
Hydrochloric acid
Use of unit as a construction heater during any phase of
construction is not recommended. Very low return air
temperatures, harmful vapors, and operation of the unit
with clogged or misplaced filters will damage the unit.
However, if the installation and operating conditions
specified below are followed, use of this unit for heating of
buildings or structures under construction is permissible:
The vent hood must be installed per these installation
instructions.
A room thermostat must control the furnace. The use
of fixed jumpers that will provide continuous heating is
not allowed.
The return air duct must be provided and sealed to
the unit.
Return air temperature must be maintained between
60°F (16°0) and 80°F (27°0).
Air filters must be installed in the system and must be
maintained during construction.
The input rate and temperature rise must be set per
the unit rating plate.
100% outdoor air must be provided for combustion air
requirements during construction, installation of this unit
in its intended outdoor location will accomplish this.
The heat exchanger, components, duct system, air
filter(s), and evaporator coil must be thoroughly
cleaned following final construction cleanup.
Following the final cleaning, all furnace operating
conditions (including ignition, input rate, temperature
rise, and venting) must be verified according to these
instructions.
Exercise care when moving the unit. Do not remove any
packaging until the unit is near the place of installation. An
accessory lift kit can be purchased to aid in rigging (see
Figure 1). Spreaders whose length exceed the largest
dimension across the unit must be used across the top
of the unit. Recommended spreader length: 3 ton and
smaller package units - 44", 3.5 ton and larger units - 54".
Units may also be moved or lifted with a forklift while still in
the factory-supplied packaging. The lengths of the forks
of the forklift must be a minimum of 42".
