design. The following manufacturer recommendations
serve as a general guide and should not replace a
qualified professional's piping system design.
Moving machinery and electrical power hazards . May
cause severe personal injury or death . Disconnect
and lock off all power before servicing equipment.
Sharp edges are inherent to sheet metal parts,
screws, clips, and similar items . May cause personal
injury .
Exercise caution when servicing equipment.

Planned Maintenance

Preventive maintenance is the best way to avoid unnecessary
expense and inconvenience. Have this system inspected at
regular intervals by a qualified service technician. The required
frequency of inspections depends upon the total operating time
and the indoor and outdoor environmental conditions. Routine
maintenance should cover the following items:
• All blowers, including furnace inducer, have sealed
bearings. No lubrication is necessary.
• Tighten all wire connections.
• Clean the outside and inside coils mechanically or with
cold water, if necessary. Usually any fouling is only
matted on the entering air face of the coil and can be
removed by brushing or vacuuming.
• Clean or replace the filters as required.
• Check for blockage of the condensate drain. Clean the
condensate pan as needed.
• Check the power and control voltages.
• Check the running amperage of all motors.
• Check all operating temperatures and pressures.
• Check and adjust all temperature and pressure controls
as needed .
• Check and adjust all damper linkages as needed.
• Check the operation of all safety controls.
• Check the condenser fans and tighten their setscrews.
• Periodic removal of snow drifts will be required in
northern climates

Unit Storage

Location
The Rebel is an outdoor unit. However, the construction
schedule may dictate storage either on the ground or in its
final position at the site. If the unit is stored on the ground,
additional precautions should be taken as follows:
• Make sure that the unit is well supported along the length
of the base rail.
• Make sure that the unit is level (no twists or uneven
ground surface).
• Provide proper drainage around the unit to prevent
flooding of the equipment.
• Provide adequate protection from vandalism, mechanical
contact, etc.
• Make sure all doors are securely closed and all latches closed.
• Units should be fitted with covers over the supply and
return air openings.
