K. CONDENSATE DRAIN
The air handler drain pan has ¾” FPT primary and
secondary connections whether used in an upflow or
horizontal configuration. Piping from each stub is to
have a 1½” minimum trap and each run pitched so as
to provide for adequate drainage and secondary
fittings together into a common drain. When an air
handler is installed above a finished ceiling, an
auxiliary drain pan must be provided under the unit
as required by most local building codes. The
secondary drain must be piped to a location that
would provide the occupant a warning if the primary
drain is blocked.
L. AIR FILTER
Air handlers are factory equipped with an air filter.
If the return grille has its own filter, the filter
installed in the air handler should be removed. Air
filter should be inspected and cleaned or replaced as
often as is necessary to prevent restriction of air flow
(minimum every three months for normal
installations). Always replace the filter with the
same type originally furnished.
M. CHECK TEST AND START UP
TURN OFF POWER AT BREAKER PANEL
Electric heaters are high current devices. Verify that
all electrical connectors, whether push-on or
compression-type are tight. Loose connections will
cause the wire and/or terminal to fail.
The unit should be tested after the system has been
completely installed to determine proper operation.
Energize the unit by switching on the line voltage
source and the thermostat.
N. PERIODIC MAINTENANCE
Inspect and clean or replace filters at least every three
months to ensure good airflow and optimum system
capacity, efficiency and life. This equipment should
NEVER BE RUN WITHOUT AN AIR FILTER in
place (see Section AIR FILTER). The blower motor
is permanently lubricated. ALWAYS disconnect
power before removing access doors!
