Installing the Drain Line
✓
Drain tubing should have an inside diameter of half an inch.
✓
The drain line must extend from the unit to an external open floor drain or condensate
pump (an external trap is not required as HEPAir units are built with an internal trap).
✓
Splice the drain line onto the drain outlet with a short piece of half inch copper tubing and
secure the drain line to the unit with a hose clamp.
The HEPAir unit is provided with a built-in drain trap. The drain trap creates a water seal to
prevent air from backing up into the drain pan and causing the drain pan to overflow. Do not
create secondary traps in the external drain line.
Allow enough height for the drain line to function properly. If draining into a nearby sink, the unit
must be elevated higher than the rim of the sink in order for the water to drain by gravity. Install
with a one-quarter inch per linear foot of pitch.
Do not
tie the condensate drain line directly into
the sanitary sewer system. See Accessories and Optional Equipment section for information about
the condensate pump.
Priming the Drain Trap
The internal drain trap primes itself automatically once the unit has run for a period of time and
after the unit cycles off. This is confirmed by water dripping from the drain.
Wiring the Unit for Power
DANGER
ELECTRICAL SHOCK HAZARD
RISK OF SERIOUS INJURY OR DEATH
The electrical outlet and wiring installation must meet the
national and local building codes.
DO:
✓
Match the electrical wiring to the cord provided on the HEPAir.
✓
Provide dedicated circuit and wiring for the system.
✓
Match the wiring and breaker size to the rated load as shown on the serial
plate and in this guide. See sample serial plate illustration on the following page.
