Heat Exchanger; Cooling System - Airxcel Suburban DynaPack S Serie Manuel Utilisateur

Disconnect all electrical power to the unit before conducting any maintenance procedures. Failure to disconnect
the power could result in personal injury or death.
4.1 BURNERS
The burners can be removed for cleaning or changing orifices.
PLEASE NOTE: This service must be performed by a qualified technician.

4.2 HEAT EXCHANGER

The heat exchanger should be inspected periodically by a qualified technician and cleaned if necessary. If cleaning is necessary, use
a stiff brush with a wire handle to remove scale and soot. While cleaning the heat exchanger, the vent extension tube should also be
cleaned. Remove the four screws on the combustion blower mounting plate and take out the blower. Use a brush to clean the vent
extension tube.

4.3 COOLING SYSTEM

The refrigeration system normally requires no maintenance
since it is a closed, self-contained system. Periodic maintenance
is limited to:
•
Cleaning the air filter. Follow directions noted on the filter
and label attached to the access panel.
•
Cleaning the condenser coil if covered with any foreign
material, lint, leaves, or other obstructions.
•
Clean the condensate drain and ensure there are no
obstructions.
On DYPA12 models, place a thermometer on the compressor
suction line above the accumulator. Connect a pressure gauge
to the suction line pressure port. Use a R410A saturated
temperature chart to calculate the suction super heat. Acceptable
values are shown on the chart to the right.
