Drain Hose Connection - The KCA/KCW is equipped with a high lift internal conden-
sate pump. Maximum lift is 20’. Use the provided 3/8” flexible hose and connect it to
the 3/8” male connection on the unit for the evaporator coil condensate drain. The
drain line must be located so it will not be exposed to freezing temperatures. The
drain should be the full size of the drain connection. (Connect the drain hose to the
condensate drain or the janitor closet.) A 1/2” ID (5/8” OD), PVC tubing or 3/8”
copper tubing is required for the drain. Insulate the drain hose; condensation may
occur during humid conditions. (Field supplied material). Plug in the 3/8” drain hose
onto the unit and install the hose clamp. Then connect the 3/8”flexible line to the field
supplied condensate line. Make sure the hose does not leak.
NOTE: do not use more than 15’ of drain hose vertically. This is maximum head
(lift) of the condensate pump.
When securing the drain hose to the highest vertical position (no more than 15’ high)
and running the hose to the drain, run the drain hose on a downward slope at a
minimum rate of 1/4” per foot for proper drainage.
Check the following items: No kinks or bends in the drain hose; No traps in the drain
hose; The end of the drain hose should be higher than the water level at the drain;
No dripping from the drain hose at the clamping area

Wall Thermostat Connection
- Preparation for thermostat connection:
H.
Use with a single stage wall thermostat. (Type: standard 24 volt input system)
Set the wall thermostat to cooling system mode, since most wall thermostats are
designed for both heating and cooling.
Prepare the wire harness for connection from the unit to the thermostat. The
recommended wire size is: Wire Type: Thermostat cable / Solid Wire 16-26 AWG.

Install the wall thermostat to the proper location inside the room where it can be
conveniently accessed. Do no install the wall thermostat where unusual heating
conditions might be present ( i.e. hot pipes, direct sunlight, etc.). Install the
thermostat somewhere close to the area of the return filter grill.
Most standard thermostat devices will provide these basic functions:
Fan mode: ON / AUTO (Select the desired fan mode)
System mode: Cool / Heat 5.
