Figure 5 - Condensate Piping
Figure 6 - Sectional View of Condensate Trap Requirements
Trap the condensate as shown in Figure 5. The P-trap dimensions in Figure 6 are sized for
a maximum return air static of 2.0" of water. If your return air static exceeds this
specification, consult Desert Aire for help in resizing the P-trap.
You may also need to install a cleanout tee or plug near the trap. Note that the drain opening
in the drain pan is off-center to simplify its cleaning and servicing. Once you have designed
and installed the trap, follow this sequence:
1.
Connect the trap to a main drain line with 1/4" of downward pitch per linear foot of run.
2.
Support the drain pipe every five feet to prevent sagging.
3.
After you install the drain piping, prime the trap by pouring water into the drain pan of
the dehumidifier.
