CONDENSATE DRAINS AND PIPING
The drain pans are connected to a common drain system. Connections are available on both sides of the base frame as
well as under the unit. The connection underneath the unit comes temporarily plugged from the factory. Field installation
of negative pressure condensate drain traps is required using one of these three connections. The non-trapped drain
connections must be permanently capped with a suitable PVC plug. See Figure 4-3 for more detail on the sizing and
materials of the negative pressure condensate drain trap.
For outdoor units, wrap drain lines and trap with electric heat tape (follow manufacturer’s instructions) controlled by an
automatic thermostat set at a minimum of 35°F to protect against freezing. Outdoor units also require insulation of all
external condensate piping. Insulation must be sealed at all seams.
NOTE
Power for heat tape must be supplied external to the PoolPak unit.
If the drain traps are vented to ambient pressure, they can be tied together after trapping and directed towards the nearest
roof or oor drain. Provisions MUST be made for disposal of condensate as directed by local plumbing code.
!CAUTION
If condensate is returned to a closed lter system that does not have a surge tank,
care must be taken to ensure free ow of condensate back to the closed lter.
For additional questions or concerns regarding installation of condensate drains, please contact PoolPak™ Service.
