OBSERVED WHEN INSTALLING THE UNIT
IMPORTANT NOTE: Remove wood shipping rails prior to installation
of the unit. See important note under Roof Curb Installation Only.
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: This appliance is a dedicated downflow design.
Proper installation of the unit ensures trouble-free operation.
Improper installation can result in problems ranging from noisy op-
eration to property or equipment damages, dangerous conditions
that could result in injury or personal property damage. Damage
or repairs due to improper installation are not covered under 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.
WARNING
,
PROPERTY DAMAGE
,
THE FOLLOWING BULLET POINTS MUST BE
.
•
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.
•
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 between 50° F and 100° 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.
•
As indicated on the unit data plate, a minimum clearance of
36" to any combustible material is required on the furnace
access side of the unit. All combustible materials must be
kept out of this area.
•
This 36" clearance must also be maintained to insure
proper combustion air and flue gas flow. The combustion
air intake and furnace flue discharge must not be blocked
for any reason, including blockage by snow.
