3. Safe Installation Requirements
FIRE, EXPLOSION, ELECTRICAL SHOCK HAZARD
Installation or repairs made by unqualified persons can result in hazards to you and others. Installation MUST
conform with local building codes or, in the absence of local codes, with the ANSI Z223.1 and the National Elec-
trical Code NFPA70-current edition or in Canada the
National Standard CAN/CGA B149-1 and CSA C.22.1 - Canadian Electrical Code Part 1.
Failure to carefully read and follow all instructions in
this manual could result in furnace malfunction, prop-
erty damage, personal injury and/or death.
The information contained in this manual is intended for use by a qualified service technician familiar with
safety procedures and equipped with the proper tools and test instruments.
• Seal supply and return air ducts. 42701 1101 oo
3
• Check to see that filters are installed correctly and are the proper type and size.
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.
REDUCED UNIT LIFE HAZARD
Failure to follow this caution may result in property damage
Do NOT operate unit in a corrosive atmosphere con- taining chlorine, fluorine, or any other corrosive
chemicals.
4. Locating The Unit
The unit is designed for outdoor installation only. Place the unit on a platform at ground level. The unit may be installed on a concrete
slab of 48" (1219mm) x 48" (1219mm) dimensions. Concrete blocks on a 3" sand footing will also work. The slab or blocks
SHOULD NOT be in contact with any part of the structure. Check Installation
local codes covering zoning, noise, platforms, etc..
Avoid locating next to fresh air intakes, vent or bedroom windows.
Noise may carry into the openings and disturb people inside.
Avoid installations under roof overhangs without guttering. Water draining from the roof onto the unit could produce excessive noise, and may cause ice to build up on coil or fan.
Placement of the unit should be in a well drained area or the unit MUST be supported high enough so runoff will not enter the unit.
Do not locate unit where heat, lint or exhaust fumes wil! be
discharged on unit (as from dryer vents.)
Clearances
The unit must be installed with a slope no greater than 1/8" per foot (10mm per meter). For side to side leveling, the
condensate drain side side MUST always be lower.
The unit MUST be situated in such a way as to provide safe access for servicing.
The platform may be made of either concrete or pressure treated wood and MUST be level and strong enough to
support the unit's weight.
Minimum clearances, as specified in FIGURE 1, MUST be
maintained from adjacent structures to provide adequate air circulation and room for service personnel.
Position platform separate from the building's foundation.
NOTE:
While minimum clearances are acceptable for safety reasons, they may not allow adequate air circulation around the unit for proper operation. Whenever possible, it is desirable to allow
additional clearance, especially around the condenser inlet and discharge openings.
Do NOT install the unit in a recessed or confined area that will
permit discharged air from the condenser to recirculate to the condenser inlet.

install in a well-drained area, with the top surface of the platform above grade level and above the average winter snow levels to prevent coil blockage.
Platform MUST be high enough to allow for proper condensate drainage.
Installing Duct Collars
Duct collars are supplied with the unit but are not factory installed.
The collars are shipped under the blower motor. See Figure 2.
1.Remove the collars from under the blower motor.
2.Position flange holes with existing screw holes on side wrapper.
3.Install screw in each collar so it goes through both of the
holes in the collar and wrapper.

Condensate Drain
The condensate drain outlet is a 3/4" (19.1 mm) threaded female
PVC connection located at the bottom of the unit to the left of the
evaporator access panel. The circulating blower and the condenser fan create a negative
pressure on the condensate drain line that wil! prevent the condensate from draining properly without a trap. To combat this
negative pressure, a field supplied condensate trap that will allow a standing column of water of at least 2" (50.Smm) MUST be
installed. The outlet of the trap must be at least 1" below the unit
drain connection. Install the trap as near to the unit as possible
for proper drainage.
A 3/4" (19.1 mm) drain line MUST be installed if required by local codes or if location of unit requires it. Run the drain line to an open
drain or other suitable disposal point as designated by local code.

Electric Heat
A variety of accessory electric heaters ranging from 5.0 to 20.0
KW provide heat in the unit when required. Each package has a
heater module that mounts on the blower inlet; mounting this module requires removal of the blower assembly and attachment
of the module to the blower standoffs provided. Each package also includes an associated remote mounted heater control
package. Integral harnesses provided with both the heater module and control package allow connection of the two
components via in-line plugs. Heaters are available both with and without circuit breakers.
See installation instructions provided with the electric heater for specific installation and application details.
5. Unit Electrical Wiring
ELECTRICAL SHOCK HAZARD.
Failure to follow this warning could result in personal injury, and/or death.
Turn off electric power supply at disconnect switch or service panel before removing any access or service
panel from unit.
Unit MUST be ,grounded to electrical service panel.
NOTE: All electrical work MUST conform with the requirements of
local codes and ordinances and in the United States with National
Electrical Code ANSI/NFPA 70-1990 (orcurrent edition). Provide
line voltage power supply from a separate fused circuit with a disconnect switch (when required) located within sight of the unit.
Supply voltage, amperage, fuse and disconnect switch sizes MUST conform with local codes and ordinances.
Wiring MUST be protected from possible mechanical damage and MUST NOT interfere with removal of access panels, filters,
etc. All exposed line voltage connections MUST be made through
liquid tight conduit to prevent water from entering the unit through the electrical access..
Ground Connections
A ground lug is installed on the control plate (or electric heat mounting plate) for the ground connection. Use a copper
conductor of the appropriate size (as designated by local code) from the unit to a grounded connection in the electrical service
panel or to a properly driven and electrically grounded ground rod. See warning on this page.
Line Voltage Wiring Do NOT complete line voltage connections until unit is
permanently grounded. All line voltage connections and the ground connection MUST be made with copper wire.
Connections for line voltage are made on the unit electrical control plate. For access, remove the Blower/Electrical access
panel.
Refer to applicable wiring diagram in this Manual. Complete the
line service connections to the contactor 'L' terminals on the electrical control plate. Check all screw terminals to ensure they
are tight. NOTE: All openings must be sealed to prevent moisture from
entering the control box.
