VIII. INSTALLATION
A. GENERAL
1. PRE-INSTALLATION CHECK-POINTS
Before attempting any installation, the following points
should be carefully considered:
a. Structural strength of supporting members.
(rooftop installation)
b. Clearances and provision for servicing.
c. Power supply and wiring.
d. Air duct connections.
e. Drain facilities and connections.
f. Location for minimum noise.
2. LOCATION CONSIDERATIONS (CORROSIVE
ENVIRONMENT)
These units are designed for outdoor installations. They
can be mounted on a slab or rooftop. They are not to be in-
stalled within any part of a structure such as an attic, crawl
space, closet, or any other place where condenser air ow
is restricted or other than outdoor ambient conditions pre-
vail. Since the application of the units is of the outdoor type,
it is important to consult your local code authorities at the
time the rst installation is made.
The metal parts of this unit may be subject to rust or deteri-
oration 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 reneries are especially
corrosive.
If the unit is to be installed in an area where contaminants
are likely to be a problem, special attention should be
given to the equipment location and exposure.
a. Avoid having lawn sprinkler heads spray direction on the unit
cabinet.
b. In coastal areas, locate the unit on the side of the building
away from the waterfront.
c. Shielding provided by a fence or shrubs may give some pro-
tection.
d. Elevating the unit off its slab or base enough to allow air
circulation will help avoid holding water against the basepan.
e. 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.
f. Regular cleaning and waxing of the cabinet with an automo-
bile polish will provide some protection.
g. 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 benet, but the
effectiveness of such coating materials cannot be veried by
the equipment manufacturer.
The best protection is frequent cleaning, maintenance and
minimal exposure to contaminants.
B. OUTSIDE SLAB INSTALLATION
(Typical outdoor slab installations are shown in Figure 2.)
1. Select a location where external water drainage cannot col-
lect around the unit.
2. Provide a level concrete slab extending 3" beyond all four
sides of the unit. The slab should be sufcient above grade
to prevent ground water from entering the unit.
IMPORTANT: To prevent transmission of noise or vibration,
slab should not be connected to building structure.
3. The location of the unit should be such as to provide proper
access for inspection and servicing.
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. It is essential that the unit be elevated above the base pad
to allow for condensate drainage and possible refreezing of
condensation. Provide a base pad which is slightly pitched
away from the structure. Route condensate off base pad to
an area which will not become slippery and result in per-
sonal injury.
IMPORTANT: Avoid blocking openings in bottom of unit.
7. 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 and to allow for
proper condensate drainage.
IMPORTANT: Avoid blocking openings in bottom of unit.
C. CLEARANCES
The following minimum clearances must be observed for
proper unit performance and serviceability.
1. Provide 30" minimum clearance at the front and 18" on the
right side of the unit for service access. Provide 12" mini-
mum clearance on the left side of the unit for air inlet.
2. Provide 60" minimum clearance from top of unit.
3. Unit is design certied for application on combustible oor-
ing with 0" minimum clearance.
4. See Figure 2 for illustration of minimum installation-service
clearances.
D. ROOFTOP INSTALLATION
1. Before locating the unit on the roof, make sure that the
strength of the roof and beams is adequate at that point to
support the weight involved. (See specication sheet for
weight of unit.) This is very important and user’s responsi-
bility.
2. The unit should be placed on a solid and level platform of
adequate strength.
IMPORTANT: Avoid blocking openings in bottom of unit.
(See Figure 3). Provision for disposal of outdoor coil defrost
water runoff must be provided.
3. The location of the unit on the roof should be such as to
provide proper access for inspection and servicing.
IMPORTANT: If unit will not be put into service immediately, cover
supply and return openings to prevent excessive condensation.
WARNING
DISCONNECT ALL POWER TO THE UNIT BEFORE
STARTING MAINTENANCE. FAILURE TO DO SO CAN
RESULT IN SEVERE ELECTRICAL SHOCK OR DEATH.

IX. DUCTWORK
Ductwork should be fabricated by the installing contractor in ac-
cordance with local codes and NFPA90A. Industry manuals may
be used as a guide when sizing and designing the duct system
- contact Air Conditioning Contractors of America, 1513 16th St.
N.W., Washington, D.C. 20036.
Place the unit as close to the space to be air conditioned as pos-
sible allowing clearance dimensions as indicated. Run ducts as
directly as possible to supply and return outlets. Use of non-am-
mable waterproof exible connectors on both supply and return
connections at the unit to reduce noise transmission is recom-
mended.
It is preferable to install the unit on the roof of the structure if
the registers or diffusers are located on the wall or in the ceiling.
Consider a slab installation when the registers are low on a wall or
in the oor.
On ductwork exposed to outside air conditions of temperature and
humidity, use a minimum of 2” of insulation and a vapor barrier.
Distribution system in attic, furred space or crawl space should be
insulated with at least 2” of insulation with vapor barrier. One-half
to 1” thickness of insulation is usually sufcient for ductwork inside
the air conditioned space.
Provide balancing dampers for each branch duct in the supply
system. Properly support the ductwork from the structure.
X. FILTERS
Filters are not provided with this unit. They must be supplied and
installed in the return air duct by the installer. A eld installed l-
ter grille is recommended for easy and convenient access to the
lters for periodic inspection and cleaning. Filters must have ade-
quate face area for the rated air quantity of the unit. See General
Database for recommended lter size.
XI. CONDENSATE DRAIN
The indoor coil condensate drain ends with a PVC stub. A trap is
provided for proper condensate drainage and to prevent debris
from being drawn into the unit. Do not connect drain to closed
sewer line. It is not recommended that a PVC cement or other
permanent installation be used so that the drain line and/or drain
pan can be easily cleaned in the future. The drain trap is located
in the control box during shipping. To install, slide clear plastic tube
over drain pan connection. The white PVC trap can be oriented as
required by installation.
XII. CONDENSATE DRAIN,
OUTDOOR COIL
The outdoor coil during heating operation will sweat or run water
off. The outdoor coil will also run water off during the defrost cycle.
See Section V, Installation, for mounting precautions.
XIII.ELECTRICAL WIRING
Field wiring must comply with the National Electrical Code* and
applicable local codes.
*C.E.C. in Canada
A. POWER WIRING
1. It is important that proper electrical power is available at
the unit. Voltage should not vary more than 10% from that
stamped on the unit rating plate. On three phase units,
phases must be balanced within 3%.
2. Install a branch circuit disconnect within sight of the unit
and of adequate size to handle the starting current. (See
Heater Kit Tables.)
3. For branch circuit wiring (main power supply to unit discon-
nect), the minimum wire size can be determined from the
National Electrical Code or Canadian Electrical Code or
nameplate or from Heater Kit Tables.
4. This unit supports both single and dual point electrical con-
nection for unit and electric heat accessory.
5. Power wiring must be run in grounded rain-tight conduit.
A small side panel grants ac-
cess to a removable, sloped
drain pan (A), which helps to
ensure indoor air quality (IAQ)
throughout the life of the unit. A
drain trap (B) assembly
is provided for
convenience.
