SAFETY HAZARD! This information is intended for use by
individuals possessing adequate backgrounds of electrical
and mechanical experience. Any attempt to repair a central air
conditioning product may result in personal injury and/or
property damage. The manufacturer or seller cannot be
responsible for the interpretation of this information, nor can it
assume any liability in connection with its use.
WARNING
HAZARDOUS VOLTAGE!
Disconnect all electrical power, including remote disconnects
before installing or servicing. Follow proper lockout/tagout
procedures to ensure the power can not be inadvertently
energized. Failure to disconnect power before servicing could
result in death or serious injury.
WARNING
LIVE ELECTRICAL COMPONENTS! During installation,
testing, servicing, and troubleshooting of this product, it may
be necessary to work with live electrical components. Failure
to follow all electrical safety precautions when exposed to live
electrical components could result in death or serious injury.
WARNING
EXPLOSION HAZARD!
Do not store corrosive or combustible materials, gasoline, or
other flammable vapors or liquids near the unit. Failure to
follow this warning could result in property damage, serious
personal injury, or death.
WARNING
ELECTRICAL HAZARD!
Grounding Required! Follow proper local and state electrical
code on requirements for grounding. Failure to follow this
warning could result in property damage, serious personal
injury, or death.
Note: The small air handlers have been evaluated in accordance
with the Code of Federal Regulations, Chapter XX, Part 3280 or the
equivalent. “SUITABLE FOR MOBILE HOME USE.”
WARNING
PROPOSITION 65: This appliance contains fiberglass
insulation. Respirable particles of fiberglass are known to State
of California to cause cancer.
All manufacturer products meet current federal OSHA
Guidelines for safety. California Proposition 65 warnings are
required for certain products, which are not covered by the
OSHA standards.
California’s Proposition 65 requires warnings for products sold in
California that contain or produce any of over 600 listed
chemicals known to the State of California to cause cancer or
birth defects such as fiberglass insulation, lead in brass, and
combustion products from natural vapor.
All “new equipment” shipped for sale in California will have
labels stating that the product contains and/or produces
Proposition 65 chemicals. Although we have not changed our
processes, having the same label on all our products facilitates
manufacturing and shipping. We cannot always know “when, or
if” products will be sold in the California market.
You may receive inquiries from customers about chemicals
found in, or produced by, some of our heating and
air-conditioning equipment, or found in natural vapor used with
some of our products. Listed below are those chemicals and
substances commonly associated with similar equipment in our
industry and other manufacturers.
WARNING
HAZARDOUS VAPORS! Do not install an air handler with a
non-ducted return in the same closet, alcove, or utility room
as a fossil fuel device. Hazardous vapors can be distributed
throughout the conditioned space and equipment damage can
result.
Important: These instructions do not cover all variations in systems
nor provide for every possible contingency to be met in connection
with the installation. 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.
Important: Installation of this unit shall be made in accordance with
the National Electric Code, NFPA No. 90A and 90B, and any other
local codes or utilities requirements.

Environmental Health Hazard Assessment), at www.oehha.org.
Consumer education is important since the chemicals and
substances on the list are found in our daily lives. Most
consumers are aware that products present safety and health
risks, when improperly used, handled and maintained.
CAUTION

WARNING
CORROSION HAZARD! To prevent shortening its service life,
the air handler should not be used during the finishing phases
of construction. The low return air temperatures can lead to
the formation of condensate. Condensate in the presence of
chlorides and fluorides from paint, varnish, stains, adhesives,
cleaning compounds, and cement creates a corrosive
condition which may cause rapid deterioration of the cabinet
and internal components.
CAUTION
SAFETY HAZARD! Sharp Edge Hazard. Be careful of sharp
edges on equipment or any cuts made on sheet metal while
installing or servicing. Personal injury may result.
BLOWER MOTOR
SHIPPING BOLT
Make sure the blower motor support is tight
(3-motor mount bolts) then check to see if
wheel is secured to motor shaft before
operating unit.

3.1 Unpacking
Carefully unpack the unit and inspect the contents for damage. If
any damage is found at the time of delivery, proper notification and
claims should be made with the carrier.
Check the rating plate to assure model number and voltage.
Furthermore, check that kits match with what was ordered.The
manufacturer should be notified within 5 days of any discrepancy or
parts shortage.
3.2 Location
The small air handler should be centrally located and may be
installed in a closet, alcove, utility room, or basement. Minimum
clearances must be met.
The air handler comes standard with two different options for
mounting, wall mount or frame mount. Both mounting options require
the unit to be level from side to side and from front to back in order to
allow condensate to properly drain from the unit. Failure to do this will
result in condensate leaking out from the unit, potentially causing
structural damage to the surrounding support structures, dry wall,
carpet, etc. Also, both mounting structures require the ability to
accommodate a minimum of 150 lb load. Failure to do this will cause
damage to the support structure and potentially damage the unit.

3.2.1 WALL MOUNT
The air handler comes standard with a wall mounting bracket and air
handler mounting bracket. Reference Figure 3-1 for more detail.
1. Remove lower wall mounting bracket from the back of the unit by
removing one screw which attaches the bracket to the air handler.
Note: Discard the screw after you have removed the wall mounting
bracket.
2. Install bracket on the wall by using 3 wood screws (not provided).
Make sure the bracket is level in order to provided proper drainage
from the unit. Note: Do not attach the wall mounting bracket into
unsupported dry wall. Make sure that the wood screws are going into
a structure that can suppport a minimum load of 150 lb.
3. Lift the air handler above the wall mounting bracket and attach the
unit to the installed bracket. Reference Figure 3-1.
4. Install the additional bottom plate for extra support for this type
mounting (see figure 3-1).
Note: The additional plate is shipped in the bottom of the shipping
carton.
3.2.2 FRAME MOUNT
The air handler comes with 8 clearance holes (4 on each side). These
holes are used to mount the air handler inside of a frame structure
(see Figure 3-2). When mounting in this fashion, make sure that the
wood screws are mounted from within the air handler and not from
outside the unit in order to avoid damaging the coil. If the frame does
not provide support in the front of the unit and additional support is
needed, open up the tabs and fix the unit to the frame or other
support structure with screws. Select a solid and level site to ensure
proper installation of the frame mount. Verify that there is sufficient
space for installation and maintenance.(see Figure. 3-3)
