Installation
General
1 INSTALLATION — Install this unit in accordance with
The American National Standard Z223.1-latest edition
manual entitled “National Fuel Gas Code,” and the
requirements or codes of the local utility or other authority having jurisdiction.
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.
These publications are available from:
National Fire Protection Association, Inc.
Batterymarch Park
Quincy, MA 02269
2 PRE-INSTALLATION CHECK-POINTS — Before
attempting any installation, carefully consider the following points:
Structural strength of supporting members
(Rooftop Installation)
Clearances and provision for servicing
Power supply and wiring
Gas supply and piping
Air duct connections and sizing
Drain facilities and connections
Location for minimum noise and vibration - away from
bedroom windows
IMPORTANT: Before operating unit, remove compressor shipping supports from the compressor base. Failure to remove supports will casue noise and vibration.
Location Consideratons
The metal parts of this 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.
3 Shielding by a fence or shrubs may give some protection.
4 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.
5 Regular cleaning and waxing of the cabinet with an auto-
mobile polish will provide some protection.
6 A liquid cleaner may be used 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.
Outside Installation
(Typical outdoor slab installation is shown in Figure 9.)
1 Select a location where external water drainage cannot
collect around unit.
2 Provide a level slab sufficiently high enough above grade
to prevent surface water from entering the unit
3 Locate the unit to provide proper access for inspection
and servicing as shown in Figure 12.
4 Locate unit where operating sounds will not disturb
owner or neighbors.
5 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.
6 Where snowfall is anticipated, the height of the unit
above the ground level must be considered. Mount unit
high enough to be above anticipated maximum area
snowfall and to allow combustion air to enter the combustion air inlet.
7 Select an area which will keep the areas of the vent, air
intake, and A/C condenser fins free and clear of obstructions such as weeds, shrubs, vines, snow, etc. Inform the
user accordingly.
Attaching Exhaust and Combustion Air
Inlet Hoods
IMPORTANT: Do not operate this unit without the exhaust/combus-
tion air inlet hood properly installed. These hoods are shipped in
cartons in the blower compartment inside the unit and must be
attached when the unit is installed. See Figure 4.
Power supply to unit must be disconnected before making
field connections. To avoid electrical shock, personal injury
or death, be sure to rigorously adhere to field wiring procedures regarding proper lockout and tagout of components.
