PROPOSITION 65: This appliance contains berglass insulation. Respirable particles of

berglass 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 berglass insulation, lead in brass, and combustion products from natural gas.

All “new equipment” shipped for sale in California will only have labels stating that the product

contains and /or produces Proposition 65 chemicals. We cannot always know “when, or if”

products will be sold in the California market, thus all products may not be labeled when their

nal destination is unknown.

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 gas used with some of our

products. Listed below are those chemicals and substances commonly associated with similar

equipment in our industry and other manufacturers.

Glass Wool (Fiberglass) Insulation

Carbon Monoxide (CO).

Formaldehyde

Benzene

More details are available at the websites for OSHA (Occupational Safety and Health

Administration), at www.osha.gov and the State of California’s OEHHA (Ofce of 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.

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. To avoid electrical

shock, which can result in injury or death, use only the

screws furnished with the motor from the manufacturer.

HDG Series Air Handler INSTALLATION INSTRUCTIONS Heat Controller, Inc.

Do not install this unit in manufactured (mobile) homes. Improper installation is more likely in

manufactured housing due to ductwork material, size, location and arrangement. Installations in

manufactured housing can cause re resulting in property damage, personal injury or death.

EXCEPTION: Manufactured housing installations are approved only with documentation by a

recognized inspection authority that veries that the installation has been made in compliance

with the instructions and all warnings have been observed.

Duct leaks can create an unbalanced system and draw pollutants such as direct, dust, fumes

and odors into the home causing property damage. Fumes and odors from toxic, volatile or

ammable chemicals, as well as automobile exhaust and carbon monoxide (CO), can be drawn

into the living space through leaking ducts and unbalanced duct systems causing personal injury

or death (see Figure 1).

• If air-moving equipment or ductwork is located in garages or off-garage storage areas, all joints,

seams, and openings in the equipment and duct must be sealed to limit the migration of toxic

fumes and odors including carbon monoxide from migrating into the living space.

• If air-moving equipment or ductwork is located in spaces containing fuel burning appliances

such as water heaters or boilers, all joints, seams and openings in the equipment and duct

must be sealed to prevent depressurization of the space and possible migration of combustion

byproducts including carbon monoxide into the living space.

When used in cooling applications, excessive sweating may occur when unit is installed in an

unconditioned space. This can result in property damage.

In compliance with recognized codes, it is recommended that an auxiliary drain pan be installed

under all evaporator coils or units containing evaporator coils that are located in any area of a

structure where damage to the building or building contents may occur as a result of an overow

of the coil drain pan or a stoppage in the primary condensate drain piping.

The rst 36 inches of supply air plenum and ductwork must be constructed of sheet metal as

required by NFPA 90B. The supply air plenum or duct must have a solid sheet metal bottom

directly under the unit with no openings, registers or exible air ducts located in it. If exible supply

air ducts are used they may be located only in the vertical walls of rectangular plenum, a minimum

of 6 inches from the solid bottom. Metal plenum of duct may be connected to the combustible oor

base, if not, it must be connected to the unit supply duct exposed to the supply air opening from the

downow unit. Exposing combustible (non-metal) material to the supply opening of a downow unit

can cause a re resulting in property damage, personal injury or death.

Exception warning to downow:

Installations on concrete oor slab with supply air plenum and ductwork completely encased

must be not less than 2 inches of concrete (See NFPA 90A).

strands of all wires are inserted fully into lug, and no wire insulation is in lug.

• Tighten lug as tight as possible while holding circuit breaker. Check wires and make sure each wire

is secure and none are loose. Repeat for left wire bundle in left top circuit breaker lug.

• Replace breaker by inserting breaker mounting tab opposite white pull tab in opening, hook mount-

ing tab over edge in opening.

• With screwdriver or pencil, pull blue tab with hole away from breaker while setting that side of

breaker into opening. When breaker is in place, release tab, locking circuit breaker into location in

opening.

• Repeat above operation for remaining breaker(s) (if more than one is provided).

• Replace single point wiring jumper bar, if it is used, on line side of breaker and tighten securely.

• Double check wires and lugs to make sure all are secure and tight. Check to make sure unit wiring

to circuit breaker load lugs match that shown on the unit wiring diagram.

4.3 HORIZONTAL

Horizontal right is the default factory conguration for the units.

Horizontal left isn’t the default factory conguration for the units.

Conversion to Horizontal: A vertical upow unit may be converted to horizontal right by removing indoor

coil assembly and reinstalling coil as shown for right hand air supply. And reinstall coil in unit as shown

for right hand air supply.

• Reinstall the indoor coil 180° from original position. Ensure the retaining channel is fully engaged

with the coil rail. See Fig. 3.

• Rotate unit into the downow position, with the coil compartment on top and the blower compart-

ment on bottom. See Fig. 3.

• Secondary drain pan kits are required when the unit is congured for the horizontal right position

over a nished ceiling and/or living space.
