3.0 INSTALLATION
Install the unit in accordance with The American National Standard
Z223.1-latest edition booklet entitled “National Fuel Gas Code”, and
the requirements or codes of the local utility or other authority having
jurisdiction.
Unit should be installed in accordance with national and local safety
codes, including but not limit to ANSI/NFPS No. 70 or Canadian
Electrical Code Part 1, C22.1, local plumbing and wastewater codes
and any other applicable codes.
Additional helpful publications available from the “National Fire
Protection Association” are: NFPA-90A - installation of Air
Conditioning and Ventilating Systems 1985 or latest edition.
NFPA-90B - Warm Air Heating and Air Conditioning Systems 1984.
3.1 PRE-INSTALLATION CHECK-POINTS
Before installation, carefully check the following:
1. For rooftop installation, be sure the structure has enough strength
to support the weight of unit.
2. Clearances and provision for servicing.
3. Power supply and wiring.
4. Gas supply and piping.
5. Air duct connections and sizing.
6. Drain facilities and connections.
7. Location for minimum noise and vibration.
Typical outdoor installation in shown in Figure 3-2:
1. Select a location where external water drainage cannot collect
around unit.
2. Locate unit where operating sounds will not disturb owner or
neighbors.
3. The location of the unit should allow proper access for inspection
and servicing.
4. Locate unit so roof runoff water does not pour directly on the unit.
Provide gutter or other shielding at roof level. Do not locate unit in
an area where excessive snow drifting may occur or accumulate.
5. Provide a concrete slab extending 3″ beyond all four sides of the
unit. The slab should be sufficiently high enough above grade to
prevent surface water from entering the unit. The slab should be
isolated from the foundation wall.
6. Pitch the slab approximately 1/2″ so that the unit will be pitched
toward the drain. See Figure 3-3.
7. It is essential that the unit be elevated above the base pad to allow
for defrost water runoff, condensate drainage, and possible
refreezing or condensate. Route condensation off the base pad to
an area that will not become slippery and result in personal injury.
Important: Do not interfere with opening in bottom of unit.
8. Where snowfall is anticipated, the height of the unit above the
ground level must be considered. Mount unit high enough to be
above average area snowfall to prevent snow from blocking the
outdoor coil, to allow condensate runoff, and to allow combustion
air to enter the combustion air inlet.
3.2 LOCATION CONSIDERATIONS
The metal parts of the unit may be subject to rust or deterioration in
adverse environmental conditions. This oxidation could shorten the
equipment’s useful life. Salt spray, fog or mist in seacoast areas,
sulphur or chlorine from lawn watering systems, and various chemical
contaminants from industries such as paper mills and petroleum
refineries are especially corrosive.
If the unit is to be installed in an area where contaminants are
likely to be a problem, give special attention to the equipment
location and exposure:
1. Avoid having lawn sprinkler heads spray directly on the unit
cabinet.
2. In coastal areas locate the unit on the side of the building away
from the waterfront.
WARNING
Disconnect all power to the unit before starting maintenance.
Failure to do so can cause electrical shock resulting in personal
injury or death.
3. Shielding by a fence or shrubs may give some protection.
4. Elevate the unit off its slab or base enough to allow air circulation
and avoid holding water against the base pan.
5. Frequent washing of the cabinet, fan blade and coil with fresh water
will remove most of the salt or other contaminants that build up on
the unit.
6. Regular cleaning and waxing of the cabinet with a good automobile
polish will provide some protection.
7. Use a good liquid cleaner several times a year to remove matter
that will not wash off with water.
Several different types of protective coatings are offered in some
areas. These coatings may provide some benefit, but the
effectiveness of such coating materials cannot be verified by the
equipment manufacturer. The best protection is frequent cleaning,
maintenance and minimal exposure to contaminants.
3.3 OUTSIDE INSTALLATION
WARNING
This unit is designed certified for outdoor installation only.
Installation inside any part of a structure can result in inadequate
unit performance as well as property damage. Installation inside
can also cause recirculation of flue products into the conditioned
space resulting in personal injury or death.

3.7 RIGGING AND HANDING
Exercise care when moving the unit. Do not remove any packaging
until the unit is near the place of installation. Rig the unit by attaching
chain or cable slings to the lifting holes provided in the base rails.
Spreader bars, whose length exceeds the largest dimension across
the unit, MUST be used across the top of the unit.
CAUTION
Before lifting, make sure the unit weight is distributed equally
on the rigging cables so it will lift evenly.
Units may be moved or lifted with a forklift. Slotted openings in the
base rails are provided for this purpose.
CAUTION
All panels must be secured in place when the unit is lifted.
The condenser coils should be protected from rigging cable
damage with plywood or other suitable material.
