Application Information
CAUTION
Heat Pump Premature Failure Notice
Running the unit without HPSK-1 kit installed on heat pump
can cause premature unit failure. A HPSK-1 kit must be
installed on all heat pump applications.
This ceiling mount air handler is available in cooling capacities
of 1.5, 2, and 2.5 nominal tons of cooling. Electric heat models
are available in capacities of 0, 5, 6, 8 and 10 kW.
The unit is designed to be installed in a horizontal position
above a dropped ceiling. Do NOT install this unit outside the
structure. These models are designed for INDOOR USE
ONLY.
Pre-Installation Instructions
Carefully read all instructions for the installation prior to install-
ing product. Make sure each step or procedure is understood
and any special considerations are taken into account before
starting installation. Assemble all tools, hardware and sup-
plies needed to complete the installation. Some items may
need to be purchased locally. Make sure everything needed to
install the product is on hand before starting.
Before attempting any installation, the following points should
be considered:
•
Structural strength of supporting members
•
Clearances and provision for servicing
•
Power supply and wiring
•
Air duct connections
•
Drain facilities and connections
Installation Clearances
Place this unit as close to the space to be air conditioned as
possible. These units are U.L. listed for installations with zero
clearance to combustible materials. If this unit is installed in a
removable ceiling panel, ensure adequate space is available
for servicing. Run ducts as direct as possible to supply and
return outlets. Use non-flammable weatherproof flexible con-
nectors on both supply and return connections at unit to re-
duce noise transmission.
Ducting
Duct work should be fabricated by the installing contractor in
accordance with local codes. Use industry manuals such as
such as NESCA (National Environmental Systems Contrac-
tors Association, 1501 Wilson Blvd., Arlington, Virginia 22209)
as a guide when sizing and designing the duct system.
To ensure correct system performance, the ductwork is to be
sized to accommodate 375-425 CFM per ton of cooling with
the static pressure not to exceed 0.5" W.C. Inadequate duct-
work that restricts airflow can result in improper performance
and compressor or heater failure
WARNING
To prevent the risk of property damage, fire, carbon
monoxide poisoning, explosion, personal injury, or
death, do not connect ductwork to any heat producing
device such as a fireplace insert or stove.
Filters
Filters are not provided with unit, and must be supplied and
installed in the return air system by the installer. A field in-
stalled filter grille is recommended for easy and convenient
access to the filters for periodic inspection and cleaning. Fil-
ters must have adequate face area for the rated air quantity of
the unit. The minimum filter size is 20" x 20" x 1".
Condensate Drain Piping
The coil drain pan has a primary and a secondary drain with 3/4"
NPT female connections. The connectors required are 3/4" NPT
male, either PVC or metal pipe, and should be hand tightened
to a torque of approximately 37 in-lbs. to prevent damage to
the drain pan connection. An insertion depth between .355 to
.485 inches (3-5 turns) should be expected at this torque. Use
the female (3/4 NPT) threaded fitting that protrudes outside of
the enclosure for external connections.
1. Ensure drain pan hole is NOT obstructed.
2. To prevent potential sweating and dripping on to finished
space, it may be necessary to insulate the condensate
drain line located inside the building. Use Armaflex® or
similar material.
A Secondary Condensate Drain Connection has been provided
for areas where the building codes require it. Pitch the drain
line 1/4" per foot to provide free drainage. Insulate drain lines
located inside the building to prevent sweating. Install a con-
densate trap to ensure proper drainage. If the secondary drain
line is required, run the line separately from the primary drain
and end it where it can be easily seen.
