Condensate Piping - Haier GE NF97DM Service Manual

Condensate Piping

This unit is designed for either right- or left-side exit of
condensate piping. Refer to Figure 37 and Figure 38 for
condensate trap locations.

1. Determine which side condensate piping will exit the
unit, location of trap, field-provided fittings and length
of PVC pipe required to reach available drain.

2. For furnaces with a 1/2" drain connection use a 3/8
allen wrench and remove plug (Figure 44) from the
cold end header box at the appropriate location on
the side of the unit. Install field-provided 1/2 NPT male
fitting into cold end header box. For furnaces with a
3/4" drain connection use a large flat head screw driver
or a 1/2" drive socket extension and remove plug.
Install provided 3/4 NPT street elbow fitting into cold
end header box. Use Teflon tape or appropriate pipe
dope. (Figure 43)
3. Install the cap over the clean out opening at the base
of the trap. Secure with clamp. See Figure 43 and
Figure 44.
4. Install drain trap using appropriate PVC fittings, glue
all joints. Glue the provided drain trap as shown in
Figure 43 or Figure 44. Route the condensate line to
an open drain.
IMPORTANT
When combining the furnace and evaporator coil
drains together, the A/C condensate drain outlet must
be vented to relieve pressure in order for the furnace
pressure switch to operate properly.
5. Figure 40 shows the furnace and evaporator coil
using a separate drain. If necessary the condensate
line from the furnace and evaporator coil can drain
together. See Figure 41.
NOTE: If necessary the condensate trap may be
installed up to 5 feet away from the furnace. Piping
from furnace must slope down a minimum of 1/4" per
ft. toward trap.
NOTE: Appropriately sized tubing and barbed fitting
may be used for condensate drain. Attach to the drain
on the trap using a hose clamp. See Figure 39.
