Remove knockout on side that drain will be connected.

Remove access panels. Inside of unit, untie and uncoil

drain hose. Form trap in hose, make sure hose is not

kinked or deformed. Connect plate assembly to side

frame with 2 screws.

Outside of unit, connect 1" EPT fitting to plate assembly.

Run line to building drain. Horizontal runs must be pitched

¼" per foot (10 mm per 46 cm) toward drain. Do not trap

externally.

Figure 3 illustrates a typical trap and vent used with HKV

series equipment.

Each unit must be installed with its own individual line to

the building main condensate drain line or riser. Provide a

means to flush or blow out the condensate line. DO NOT

install units with a common trap and or vent.

Always vent the condensate line when dirt or air can

collect in the line or a long horizontal drain line is

required. Also vent when large units are working against

higher external static pressure than other units connected

to the same condensate main since this may cause

poor drainage for all units on the line. WHEN A VENT

IS INSTALLED IN THE DRAIN LINE, IT MUST BE

LOCATED AFTER THE TRAP IN THE DIRECTION OF

THE CONDENSATE FLOW and opening 46" (117 cm)

minimum from bottom of unit. (Vent per code)

WARNING! Ensure condensate line is pitched toward

drain 1/4" per foot [10mm per 46cm] of run.

Drain main or riser must be sized for all units connected

to it.
