GENERAL INSTRUCTIONS

IMPORTANT

The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians. All duct work, supply and return ducts,
must be properly sized for the design air flow
requirement of the equipment. ACCA is an excellent
guide to proper sizing. All duct work or portions
thereof not in the conditioned space should be properly
insulated in order to both conserve energy and prevent
condensation or moisture damage.

SHIPPING DAMAGE

Upon receipt of equipment, the carton should be
checked for external signs of shipping damage. If
damage is found, the receiving party must contact the
last carrier immediately, preferably in writing,
requesting inspection by the carrier’s agent.

GENERAL

The refrigerant system is completely assembled and
charged. All internal wiring is complete.

The unit is designed for use with or without duct work.
Flanges are provided for attaching the supply and return
ducts.

These instructions explain the recommended method to
install the air cooled self-contained unit and the
electrical wiring connections to the unit.

These instructions and any instructions packaged with
any separate equipment required to make up the entire
heat pump system should be carefully read before
beginning the installation. Note particularly “Starting
Procedure” and any tags and/or labels attached to the
equipment.

While these instructions are intended as a general
recommended guide, they do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation
is made.

FIELD INSTALLED HEATER PACKAGES
(OPTIONAL)

These packaged air conditions are manufactured
without supplementary electric heaters. Supplementary
heaters are available for simple, fast field installation.

A separate power circuit is required for the
supplementary heaters.

IMPORTANT: Refer to Table 1 when designing duct
work for maximum available static pressure with heater
installed.

Refer to data shown in Table 3 and 4 for proper
application information on all available heater
combinations and what units they can be used with. It
also shows the applicable circuit ampacities, fuse size,
and wire size for each heater combination.

70 and larger. 480V circuit breakers are not “HACR” type.
Based on wire suitable for 75 degree C. Other wiring materials must be rated for marked “Minimum Circuit Ampacity” or greater.

IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses

and conductor wires in accordance with the National Electrical Code and all existing local codes.

INSTALLATION

LOCATION

GENERAL

The unit must be located outside, or in a well ventilated
area. It must not be in the space being heated or cooled.
A sound absorbing material should be considered if the
unit is to be installed in such a position or location that
might cause transmission of sound or vibration to the
living area or adjacent buildings.

SLAB MOUNTING

In areas where winter temperatures DO NOT go below
32° F for periods over twelve hours, the unit may be
slab mounted at grade level. When installing unit at
grade level, install on a concrete slab at least four
inches above finished grade level. Slab should have a
slope tolerance away from the building structure of at
lease 1/4 inch per foot, while being level from side to
side. Place slab in a location where runoff water from
higher ground will not collect around unit. See
Figure 2.

A minimum of 18 inches should be provided between
the coil inlet and any building surfaces. Provide at least
four feet between coil outlet and any building wall,
fences or other vertical structures. Provide a minimum
of three feet clearance on the service access side of the
unit. See Figure 3.

ROOF MOUNTING

When a unit is installed in areas where low ambient
temperatures or strong winter winds exist, it should be
placed for prevailing winter winds are not in direct line
with the outdoor coil. If this is not possible, a wind
barrier should be constructed. Place barrier 24 inches
from the coil inlet side of the unit and in the direction
of prevailing winds. Size barrier at least the same
height and width as the unit. This may be necessary on
ground level installations, also. See Figure 4.

WINTER INSTALLA TION BELOW 32°F

In areas where winter conditions go below 32°F for
extended periods, the unit must be elevated above the
mounting surface to prevent snowfall or ice
accumulation from interfering with the operation of the
unit. A minimum of twelve inch elevation is
recommended, while greater elevation may be required
for areas of high snow accumulation. Poured concrete,
steel framework, brick, cement block, etc., can be
utilized to construct a suitable raised mounting
platform. See Figure 5.

TYPICAL INSTALLATIONS

1.

ROOF MOUNTED

sturdy base on the roof of the building. Return air
to the unit is brought through a single return grille
(grilles with built-in filters are best since they
enable easy access for filter changing). Return air
ducts are attached to the lower section of the front
panel. Supply air is brought from the unit to attic
duct work or to a furred down hall. Supply air duct
is attached to the top of the front panel.

CAUTION: All outdoor duct work must be

thoroughly insulated and weatherproofed. All
attic duct work must be thoroughly insulated.
Two inch thick insulation with suitable vapor
barrier is recommended for both outdoor and
attic runs.

In roof top installation, as in all installations, the air
conditioner must be level from side to side.
However, the unit should have a pitch along the
length to assure complete external drainage of
precipitation and of defrost condensate. See Figures
6 and 7, and Tables 6 and 7.

2.

CRAWL SPACE

space must be well insulated and provided with a
vapor barrier. In addition, the crawl space must be
thoroughly ventilated and provided with a good
vapor barrier as a ground cover. It is most desirable
to install the unit will be outdoors rather than inside
the crawl space, so that it will be readily accessible
for service.

3.

SLAB MOUNTED AT GROUND LEVEL

type installation is ideal for homes with a slab floor
construction where a roof mounted unit is not
desired. The supply and return duct work can be run
through a furred closet space.

4.

THROUGH THE WALL

requires a suitable framework to be fabricated
capable of withstanding the unit weight. Normally
the unit will be insulated so as to minimize supply
and return duct work.
