Salt Water Pools
For units (AW models only) installed serving a salt water pool, wire the pool bonding system to the bonding lug
on the unit copper pool water piping. This connection is required to prevent corrosion of the internal ComPak®
water piping.
For more information on salt water pools, see the article “Salt Water Pools”
in the Pool Water Chemistry section
of the PoolPak educational library.
Condensate Drains
Drain pans are connected to a common drain system and must be trapped for proper operation. For AWH
and HCDH units, a trap and piping must be supplied and installed by the customer. The trap depth must be a
minimum of 6 inches
(See Figure 4-12).
For AWV and HCDV units, a condensate trap is located inside the unit
and the field condensate piping and overflow drain must not have an additional trap.
Provisions MUST be made for disposal of condensate. Condensate from the dehumidifier coil will have nearly the
same properties as the pool water itself. It is recommended that building materials subjected to the condensate
and systems used for its disposal are checked for compatibility. For drain piping use PVC plastic pipe minimum
Schedule 40. The drain line must be sloped to provide proper drainage.
Drain line exposed to outdoor ambient temperatures must be protected against freezing. Wrap lines with electric
heat tape (follow manufacturer’s instructions) controlled by an automatic thermostat set at a minimum of 35°F to
protect against freezing. Insulate all piping. Insulation must be sealed at all seams. Power for heat tape must be
supplied external to the ComPak®.
