Drain Hose Connection
The CM25 is equipped with an internal
condensation removal pump with
maximum head lift of 4 feet (1.2 m).
1. Use the provided 1/2 inch (13 mm)
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
condensation drain or the janitor closet.)
2. PVC tubing (1/2 inch (13 mm) for ID, 5/8 inch (16 mm) for OD) is required for
the drain. Insulate the drain hose. Condensation may occur during humid
conditions.
Note: PVC tubing and insulation material are field supplied.
Note: Do not use more than 4 feet (1.2 m) of drain hose vertically. This is maximum
lift of the condensation pump.
3. To insure proper drainage, locate the drain hose to the highest vertical position,
no more than 4 feet (1.2 m) high, and run the hose to the drain on a downward
slope at a minimum rate of 1/4 inch (6 mm) per foot.
1. Plug in the 1/2 inch (13
mm) drain hose with the
supplied clip into the drain
pipe. Make sure the hose
is all the way in and flush
with the grommet.
2. Position the clip to the top
of the drain pipe near the
unit as shown.
3. Pull out the stopper and
secure hose. Make sure
there are no kinks or bends.

FEATURES OF CM25
1. The CM25 is equipped with a variable speed compressor, which is driven by
state of the art inverter technology. A variable speed compressor automatically
adjusts its speed as the heat load in the room changes. With its soft start up,
a variable speed compressor reduces start up wear on the compressor and
eliminates in-rush current resulting in no dip in the power supply.
2. Fire alarm control panel connection with automatic shut off.
3. Automatic shut off by warning signal output and alarm for temperature sensor
failure, and conditions of self-diagnostic codes.
4. Automatic restart feature when the power is lost and regained.
The unit returns to the operating mode it was in prior to the loss of power.
Any preset program is retained in the memory in the event power loss occurs.

DAILY INSPECTION & MAINTENANCE
Cleaning Air Filters
The air filter on the evaporator return grill should be checked weekly for dust
buildup.
Clean or replace air filter on a weekly basis. If the unit is used in a dusty
environment, more frequent cleaning may be required.
A dirty air filter can reduce the air output, resulting in a decrease in cooling
capacity.
Cleaning Condenser Air Intake
Inspect and remove dust buildup on the condenser air intake of the unit with a
vacuum cleaner periodically to prevent insufficient cooling.
Ground Fault Breaker Testing
The ground fault breaker should be tested at least once a month.
