CONQUEST 90 - Filling the Trap; Condensate Pump

'
f
FILLING THE TRAP
FILL THE TRAP ASSEMBLY WITH
WATER BEFORE OPERATING
THE FURNACE. Do this by
removing the drain hose from the
trap or from the connection to the
secondary coil. Pour about a cup of
water into the vent trap. Any excess
water flows into the house drain
when the trap is full. See Figure 57.
If local codes require. install a
condensate neutralizer cartridge in
the drain line. Install this cartridge
in a horizontal position only. Also
install an overflow line if routing to a
floor drain.
CONDENSATE PUMP
If no floor drain is available. install a
condensate pump that is resistant to
acidic water. These pumps are
available from your local distributor.
If the pump used is not resistant to
acidic water, a condensate
neutralizer must be used ahead of
the pump.
The condensate pump must have an
auxiliary safety switch to prevent
operation of the furnace and
resulting overflow of condensate in
the event of pump failure. Wire the
safety switch through the low
voltage "R" circuit only to provide
protection in both heating and
cooling modes.
IMPORTANT: DO NOT RUN THE
DRAIN OUTDOORS. FREEZING
OF CONDENSATE CAN CAUSE
CONDENSATE BACK UP
SHUTTING DOWN THE FURNACE
AND POSSIBLY OTHER
PROPERTY DAMAGE.
