SERVICE AND MAINTENANCE .
filter
The MaxAir
™ series air handlers are not
provided with a filter. A good quality filter
should be installed and or replaced or
cleaned monthly.
A CLOGGED OR INADEQUATE FILTER
MAY VOID PRODUCT WARRANTY.
duct cleaning
If proper filter maintenance is adhered to,
duct cleaning is not required for the life of the
equipment.
coils
Air conditioning and heating coils should not
require cleaning if the filter maintenance
schedule is adhered to. If a filter is damaged
or collapses from plugging, the coils may get
fouled by dust. If this happens, replace the
filter and carefully vacuum the coils. The fan
may need to be removed to gain access to
the face of the heating coil.
air conditioning coil
At the start of each cooling season, check
the drain connection to the cooling coil to
ensure it is free of debris. An easy way to do
this is to blow into the tube to see if there is
any obstruction. If a plugged air conditioning
coil is suspected, call a service technician for
testing and cleaning.
fan and motor
Check fan for dust once a year. If dirty,
vacuum or wash to remove dust. Keeping the
fan blades clean will reduce noise and
improve the capacity and efficiency of the
heating system. Take care to avoid wetting
the motor! Remove the motor if required.
external pump
The circulating pump is water lubricated and
should require no regular maintenance. If the
pump fails to start at the beginning of the
heating season, follow the instructions in the
Trouble Shooting section of this manual
below.
RUNNING THE PUMP WITH THE
ISOLATION VALVES CLOSED OR WITH
NO WATER IN THE SYSTEM WILL
DAMAGE THE PUMP
NOTE: THE MAXAIR
™ FAN COILS ARE NOT TO BE USED FOR TEMPORARY HEAT
DURING CONSTRUCTION. USE FOR THIS PURPOSE WILL VOID EQUIPMENT WARRANTY.
