2. SAFE INSTALLATION REQUIREMENTS

FIRE AND ELECTRICAL SHOCK HAZARD

Failure to carefully read and follow all instructions in this

manual could result in furnace malfunction, personal

injury, death and/or property damage.

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 National Electrical Code
NFPA70-2005 or in Canada and CSA C.22.1 - Canadian

Electrical Code Part 1.

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.

• Check to see that filters are installed correctly and are
the proper type an size.

NOTE: It isthe 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

ACCESS PANELS

See Figure 1 for a general view of unit and location of
access panels.

CLEARANCES

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.
NOTE: Units with available filter racks (3-1/2 to 4 ton), need

a26" minimum clearance at side of unit for removal of filters.
See chart below if unit is going to be placed near

combustible construction or materials.
While minimum clearances are acceptable for safety

reasons, they may not allow adequate air circulation around

the unit for proper operation inthe cooling mode. Whenever

possible, it is desirable to allow additional clearance,

especially around the condenser inlet and discharge
openings.

Do NOT install the unit in a location that will permit

discharged air from the condenser to recirculate to the
condenser inlet.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in shorten
life

Ci_oU_ltooprr_°e_r_Sunit in a corrosive atmosphere

containing chlorine, fluorine, or any other corrosive
chemicals.

INSTALLATION

NOTICE

Unit will NOT operate properly unless it is installed lev-

el front to rear and side to side. The slope MUST NOT be
greater than 1/8" per foot (10mm per meter). For side to
side leveling, the drain side MUST always be lower.

Ground Level Installation

Ground level platform requirements:

- The unit MUST be situated to provide safe access for
servicing.

- The unit must be level and supported above grade by

beams, platform, or a pad. Platform or pad can be of

open or solid construction but should be of permanent

materials such as concrete, bricks, blocks, steel, or

pressure-treated timbers approved for ground contact.
Soil conditions must be considered so that the platform
or pad does not shift or settle and leave the unit partially
supported.

- Position platform separate from building foundation.

- Install inwell-drained area, with top surface of platform
above grade level.

- Platform must be high enough to allow for proper
condensate trap installation and drainage. See

FIGURE 2 and associated text for more information

about condensate drainage.

Rooftop Installation

Rooftop platform requirements:

- The unit MUST be situated to provide safe access for
servicing.

- The existing roof structure MUST be adequate to
support the weight of the unit or the roof MUST be

reinforced.

Check the weight of the unit in relation to the roof
structure and local building codes or ordinances and

reinforce roof structure if necessary. See page 11 of this
manual for unit weights.

- Support for the unit MUST be level and strong enough
to carry unit weight. The support may consist of a

platform or a combination of platform and roof beams or

curb.

- See Hoisting section for hoisting instructions.

HOISTING
NOTE: All access panels MUST be secured in place before

hoisting.

The unit should be hoisted with two lifting slings. Attach the
slings to rigging shackles that have been hooked through

holes in the base rail.

Two spreader bars MUST be placed on top of the unit to

protect the unit from damage from the pressure exerted by

the slings. Make sure that all equipment is adequate to

handle the weight ofthe unit and that the slings will not allow

the unit to shift.

Refer to FIGURE 9 on page 11 ofthis manual for illustrated
rigging instructions and weight chart.

DOWNFLOW CONVERSION
NOTE: In downflow applications with roof curbs or jack

stands, the center rail under the unit must be removed. The
center rail is attached to the base rail with screws.

These units are adaptable to downflow use. To convert to
downflow use, follow these steps:

1. Remove the blockoff plates found in the return air
compartment and the supply air compartment.

NOTE: Blockoff plate in the supply air compartment only

contains one screw. If reinstalling plate, back part of plate

MUST fit into mating dimples on flange. To reinstall, slant
plate into dimples, then put plate into position and fasten

with screw.

2. Install the removed plates on the horizontal return and
supply air openings.

3. Install roof curb on the building. Be sure to follow all
directions included with curb and all applicable building
codes in your installation.

Condensate Drain
The condensate drain outlet is a 3/4" (19.1 mm) female PVC

connection located at the bottom on the left hand side (see

FIGURE 2).

The circulating blower creates a negative pressure on the
condensate drain linethat can prevent the condensate from

draining properly. To combat this negative pressure, a field
supplied condensate trap that will allow a standing column

of water of at least 2" (50.8mm) MUST be installed. Top of
outlet from trap MUST be at least 1" (25.4mm) below top of
outlet from unit. 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 iflocation of unit requires it. Run the drain line

to an open drain or other suitable disposal point.

4. ELECTRICAL WIRING

ELECTRICAL SHOCK HAZARD.

Failure to follow this warning could result in personal
injury, death and/or property damage.

The unit cabinet must have an uninterrupted,

unbroken electrical ground to minimize the possibility

of serious injury if an electrical fault should occur.
This ground may consist of an electrical wire

connected to the unit ground lug in the control
compartment, or conduit approved for electrical

ground when installed in accordance with National

Electric Code (NEC) NFPA 70, and local electrical
codes. In Canada, follow Canadian Electrical Code

CSA (Canadian Standards Association) C22.1 and
local electrical codes.
