SYSTEM OPERATION

Pre-Installation Checks

Carefully read all instructions for the installation prior

to installing unit. Ensure each step or procedure is

understood and any special considerations are taken

into account before starting installation. Assemble all

tools, hardware and supplies needed to complete the

installation. Some items may need to be purchased locally.

WARNING

To prevent possible equipment damage, property damage,

personal injury or death, the following bullet points

must be observed when installing the unit.

IMPORTANT NOTE: Remove wood shipping rails prior to

installation of the unit.

All Installations:

Important Note:

Unit should be energized 24 hours

prior to compressor start up to ensure crankcase heater

has sufficiently warmed the compressors. Compressor

damage may occur if this step is not followed.

NOTE: Appliance is shipped from factory for vertical duct

application.

Proper installation of the unit ensures trouble-free

operation. Improper installation can result in problems

ranging from noisy operation to property or equipment

damages, dangerous conditions that could result in injury

or personal property damage and that are not covered by

the warranty. Give this booklet to the user and explain it’s

provisions. The user should retain these instructions for

future reference.

•

For proper flame pattern within the heat exchanger and

proper condensate drainage, the unit must be mounted

level.

•

The flue outlet must be at least 12 inches from any

opening through which flue gases could enter a

building, and at least three feet above any forced

air inlet located within ten feet. The economizer/

manual fresh air intake/motorized fresh air intake

and combustion air inlet mounted on the unit are not

affected by this restriction.

•

To avoid possible corrosion of the heat exchanger, do

not locate the unit in an area where the outdoor air

(i.e. combustion air for the unit) will be frequently

contaminated by compounds containing chlorine or

fluorine. Common sources of such compounds include

swimming pool chemicals and chlorine bleaches, paint

stripper, adhesives, paints, varnishes, sealers, waxes

(which are not yet dried) and solvents used during

construction and remodeling. Various commercial and

industrial processes may also be sources of chlorine/

fluorine compounds.

•

The unit shall not be connected to a chimney flue

serving a separate appliance designed to burn solid fuel.

•

To avoid possible illness or death of the building

occupants, do NOT locate outside air intake device

(economizer, manual fresh air intake, motorized fresh

air intake) too close to an exhaust outlet, gas vent

termination, or plumbing vent outlet. For specific

distances required, consult local codes.

•

Allow minimum clearances from the enclosure for fire

protection, proper operation, and service access (see

unit clearances). These clearances must be permanently

maintained.

•

The combustion air inlet and flue outlet on the unit

must never be obstructed. If used, do not allow the

economizer/manual fresh air damper/ motorized fresh

air damper to become blocked by snow or debris. In

some climates or locations, it may be necessary to

elevate the unit to avoid these problems.

•

When the unit is heating, the temperature of the return

air entering the unit must be a minimum of 55° F.

Ground Level Installations Only:

•

When the unit is installed on the ground adjacent

to the building, a level concrete (or equal) base is

recommended. Prepare a base that is 3” larger than the

package unit footprint and a minimum of 3” thick.

•

The base should also be located where no runoff of

water from higher ground can collect in the unit.

Roof top Installations Only:

•

To avoid possible property damage or personal injury,

the roof must have sufficient structural strength to carry

the weight of the unit(s) and snow or water loads as

required by local codes. Consult a structural engineer

to determine the weight capabilities of the roof.

•

The unit may be installed directly on wood floors or on

Class A, Class B, or Class C roof covering material.

•

To avoid possible personal injury, a safe, flat surface for

service personnel should be provided.
