RaIn
Drainage of condensate directly onto the roof may be
acceptable; refer to local code. It is recommended that a
small drip pad of either stone, mortar, wood or metal be
provided to prevent any possible damage to the roof.

RaIn
To use the bottom drain connection, remove the drain plug
from the bottom connection and install it in the horizontal
connection.

Due to the fact that drain pans in any air conditioning
unit will have some moisture in them, algae and fungus
will grow due to airborne bacteria and spores. Periodic
cleaning is necessary to prevent this build-up from plugging
the drain.

This unit is equipped with an electronic ignition device to
automatically light the main burners. It also has a power
vent blower to exhaust combustion products.
On new installations, or if a major component has been
replaced, the operation of the unit must be checked.
Check unit operation as outlined in the following
instructions. If any sparking, odors, or unusual sounds
are encountered, shut off electrical power and recheck for
wiring errors, or obstructions in or near the blower motors.
Duct covers must be removed before operating unit.
The Startup, Adjustments, and Checks procedure provides
a step-by-step sequence which, if followed, will assure the
proper startup of the equipment in the minimum amount of
time. Air balancing of duct system is not considered part
of this procedure. However, it is an important phase of any
air conditioning system startup and should be performed
upon completion of the Startup, Adjustments, and Checks
procedure. The Startup, Adjustments, and Checks
procedure at outside ambients below 55°F should be
limited to a readiness check of the refrigeration system with
the required final check and calibration left to be completed
when the outside ambient rises above 55°F.
