UNIT MAINTENANCE

Proper maintenance is most important to achieve the best performance from a air handler. Some of the components and their locations are shown in Figure 13 (page 18). If any component of the air handler must be replaced, use only factory authorized replacement parts specified in the Replacement Parts List provided online.

WARNING:

ELECTRICAL SHOCK, FIRE OR EXPLOSION HAZARD

Failure to follow safety warnings exactly could result in serious injury or property damage.

Improper servicing could result in dangerous operation, serious injury, death or property damage.

•Before servicing, disconnect all electrical power to air handler.

•When servicing controls, label all wires prior to disconnecting. Reconnect wires correctly.

•Verify proper operation after servicing.

•These maintenance instructions are primarily intended to assist qualified technicians experienced in the proper maintenance and operation of this appliance.

•Always reinstall the doors on the air handler after servicing or cleaning/changing the filters.Do not operate the air handler without all doors and covers in place.

•Verify that the thermostat is properly installed and is not being affected by drafts or heat from lamps or other appliances.

•To achieve the best performance and minimize equipment failure, it is recommended that a yearly maintenance checkup be performed. At a minimum, this check should include the following items:

Air Filter(s)

HMG**F1E, HMG**X1E & HCG**V1E series air handlers are not supplied with a single air filter when shipped from the factory. It is recommended that the filter be cleaned or replaced monthly. Newly built or recently renovated homes may require more frequent changing until the construction dust has minimized. Filter sizes shown in Table 2 are available at most local retailers.

WARNING:

Never operate the air handler without a filter in place. Dust and lint in the return air can build up on internal components, resulting in loss of efficiency,equipment damage,and possible fire.

Filters designed to remove smaller particles such as pollen, may require additional maintenance.

Blower Compartment

Dirt and lint can create excessive loads on the motor resulting in higher than normal operating temperatures and shortened service life. It is recommended that the blower compartment be cleaned of dirt or lint that may have accumulated in the compartment or on the blower and motor as part of the annual inspection.

Blower Fan Wheel

Inspect the blower wheel blades for accumulations of dirt and clean if necessary. Inspect mounting nut for tightness when done.

Blower Motor & Assembly

Inspect the blower assembly and motor mounting brackets for tightness and corrosion. Correct deficiencies if necessary. The blower motor contains sealed bearings and under normal operating conditions, no maintenance is necessary for the life of the equipment.

TROUBLESHOOTING

If the air handler fails to operate, check the following:

•Is the electric turned on?

•Is the thermostat operating properly?

•Are the blower compartment door(s) in place?

•Is the air handler disconnect closed?

•Has the circuit breaker tripped or the control board fuse burned open?

•Are any manual reset switches open?

•Is the filter dirty or plugged?

•Is the LED on both control boards constantly ON? If not, refer to Tables 3 or 4 to determine fault condition.
