These instructions do not cover all variations in systems
nor provide for every possible contingency to be met in
connection with installation. All phases of this installa-
tion must comply with NATIONAL, STATE AND LOCAL
CODES. Should further information be desired or should
particular problems arise which are not covered sufficiently for
the purchaser’s purposes, the matter should be referred to your
installing dealer or local distributor.
A. GENERAL
The following instructions cover 2A6H1, 2A6H2, 2A6H4, &
2A6H5 Heat Pump Units.
NOTICE: These outdoor units may be used with indoor
units equipped with Thermostatic Expansion Valve or
Accutron™ Flow Control Check Valve (F.C.C.V.) assembly
for refrigerant flow control only.
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 with-
stand 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 accumula-
tion and prolonged below freezing temperatures occur.
1. Units should be elevated 3 to 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 prevent-
ing 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 constructed of mate-
rials 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
structures 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 on
page 2, 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.
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. Clear-
ance must be provided in front of control box (access panels) &
any other side requiring service access to meet National Electri-
cal Code. Also, the unit location must be far enough away from
any structure to prevent excess roof runoff water from pouring
directly on the unit. Do not locate unit(s) close to bedroom(s).
