Installation

NOTE: If loop temperatures are expected below the am-

bient dew point, the optional internal insulation package

must be ordered. Insulation must also be installed on

loop water piping on those sections which run through

unheated areas or are located outside the building.

Condensate Piping

Unit is supplied with condensate drain hose, 15.9mm

I.D. ﬂexible plastic nonpressure-rated, protruding from

piping side of unit. Connect this hose to building drain.

Avoid making kinks in hose to ensure an unobstructed

ﬂow of condensate from the unit to the drain. DO NOT

twist, pull hose out, or push excess hose into unit. If

hose will not connect to your building drain several

options include, relocate end of building drain, add to

or cut hose, use hard plastic or copper elbow ﬁttings

for tight radii (put inside hose). Keep hose positioned

within or over subbase area so hose does not interfer

with front cabinet. Cabinet should not push or reroute

hose. Clamp all joints watertight. Check

for leaks.

Internally the drain hose is clamped to drain pan and

pitched correctly. Horizontal runs of condensate hose

should be pitched downward 6mm (1/4 inch) minimum

for every 300MM of hose. Avoid low points and unpitch-

ing because dirt collects in these areas and may cause

blockage. If blocked the condensate level in

drain pan increases, when level gets too high, CCE unit

has sensor switch that will shut unit off, overﬂow may

still occur.

Building drain connection if parallel with ﬂoor the

height can be up to 38mm above subbase for proper

pitch and correct drainage, up to 130mm above is

allowable but drainage will be slower. When 65 to

130mm above the hose inside unit will act as a trap.

Heights more than 130mm above subbase are NOT

allowable (condensate overﬂow may occur). Check if

your unit has a disconnect box option, this limits build-

ing drain locations. See unit Conﬁguration pages.

Field installation of a trap or vent is not required unless

speciﬁed by local codes. CCE units are designed

in a blow-through conﬁguration. The condensate

drain pan is located on the outlet side of the blower

so that the pressure in the drain pan is higher than

atmosphere.

When drain connection is completed check for proper

drainage and leaks. Correct if necessary.

If trap is used, check and clean often. See

Maintenance Instructions.
