Condensate removal (WS, WE and WY models)
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
STEP 1 Find the drain plate on the rear of the basepan and remove it. (See Figure 13).
STEP 2 Remove the knockout in the lower right side of the rear grille. Slide the chassis into the WSC SLEEVE so that the drain nipple extends through the knockout.
STEP 3 Slide the tubing inside 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.

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 WE and WY models to prevent freezing. (NOTE: In the cooling mode of the WS, WE and WY models, condensate overflow is possible in very humid climates). For these particular instances, an optional drain kit (Accessory #DK) is available for water removal.
IDK (Interior Drain Kit)
New construction allowing for condensate drain systems built within the walls can use the Friedrich Interior Drain Kit (Accessory #IDK) designed for installation in the bottom of the sleeve below the condensate bellows valve (heat/cool models only).
