WallMaster Chassis Installation Instructions
for WCT, WET and WHT models
Condensate Removal
If you desire to drain condensate from the basepan during unit
operation, this unit is provided with a drain nipple that can be attached
to the basepan. You must provide a
3
/
8
″
outside diameter thin-wall
plastic or copper tube which will attach to the drain nipple.
Follow the instructions below:
STEP 1.
Find the drain rubber plug on the rear of the basepan and
remove it (see Figure 52).
STEP 2.
Remove the knockout in the lower right side of the rear grille.
Slide the chassis into the WSE SLEEVE so that the drain nipple
extends through the knockout.
STEP 3.
Slide the tubing over the drain nipple. If the chassis must be
removed from the sleeve for service, remove the clamped drain
hose before sliding the chassis out of the sleeve.
IDK (Drain Kit)
New construction allowing for condensate drain systems built
within the walls can use the Friedrich Interior Drain Kit (Accessory
#IDK). This kit is designed for installation in the bottom of the sleeve
below the condensate bellows valve (heat/ cool models only).
Alternate Drain Kits
DK (Drain Kit)
In the event that the outdoor temperature drops below 37 °F, any water
that remains in the chassis basepan is drained into the sleeve pan
on WET and WHT models to prevent freezing. (NOTE: In the cooling
mode of the WCT, WET and WHT models, condensate overflow is
possible in very humid climates). For these particular instances, an
optional drain kit (Accessory #DK) is available for water removal.
