NOTE: THE MANUFACTURER HAS ALWAYS RECOMMENDED
INSTALLING AMERICAN STANDARD HEATING AND AIR

DOOR SYSTEMS.
THE BENEFITS OF INSTALLING APPROVED MATCHED

Check for transportation damage after unit is uncrated. Report promptly,
to the carrier, any damage found to the unit.
To determine the electrical power requirements of the unit, refer to the
nameplate of the unit. The electrical power available must agree with
that listed on the nameplate.
The Heat Pump has been designed and manufactured to withstand and
operate in severe winter conditions. However, there are precautionary
steps which should be taken at the time of installation which will help
assure the efficient operation of the unit. It is recommended that
these precautions be taken for units being installed in areas
where snow accumulation and prolonged below freezing
temperatures occur.
1. Units should be elevated three (3) to twelve (12) inches above the pad or
rooftop, depending on local weather. This additional height will allow
better drainage of snow and ice (melted during defrost cycle) prior to its
refreezing. This should prevent a buildup of ice around the unit which
occurs when unit is not elevated. Insure that drain holes in unit base
pan are not obstructed preventing draining of defrost water.
2. If possible, avoid locations that are likely to accumulate snow drifts. If
not possible, a snow drift barrier should be installed around the unit to
prevent a buildup of snow on the sides of the unit and should be of sufficient
distance from the unit to prevent restriction of airflow to and from the unit.
Also allow for proper maintenance space. The barrier should be con-
structed of materials which will blend in with the building design.
3. Avoid locating the unit where condensation and freezing of defrost

vapor may annoy the customer. For instance, installing the unit under
a bedroom, kitchen, or picture window may be annoying to the
customer since condensate and fog will occur during the defrost cycle.
4. Avoid locating the unit under the eaves or other overhead struc-
tures as sizeable icicles may form and the unit may be damaged by
these falling icicles.
B. LOCATION AND PREPARATION OF THE UNIT
1. When removing unit from the pallet, notice the tabs on the
basepan. Remove tabs by cutting with a sharp tool as shown above in
Figure 2, and slide unit off of pallet.
2. The unit should be set on a level support pad at least as large as the
unit base pan, such as a concrete slab. If this is not the application used
please reference ALG-APG0*-EN (*latest revision number).
3. The support pad must NOT be in direct contact with any structure.
Unit must be positioned a minimum of 12" from any wall or surrounding
shrubbery to insure adequate airflow. Clearance must be provided in
front of control box (access panels) & any other side requiring service
access to meet National Electrical Code. Also, the unit location must be
far enough away from any structure to prevent excess roof run-off water
from pouring directly on the unit. When choosing the location of the
unit(s), sound transmission through air and refrigerant lineset should
be taken into consideration. It is recommended to locate unit(s) away
from areas (bedrooms, etc.) where such sound could be objectionable.
4. The top discharge area must be unrestricted for at least five (5) feet
above the unit.
5. When the outdoor unit is mounted on a roof, be sure the roof will
support the unit's weight. Properly selected isolation is recommended to
prevent transmission to the building structure.
Since the manufacturer has a policy of continuous product
and product data improvement, it reserves the right to
change design and specifications without notice.
