3. Plug in the supplied 20 feet (6 m)
drain outlet hose into the drain
outlet spout of the condensate
pump.
4. Check the drainage performance
after installation. It is important that
the drainage line from the pump is
free of kinks and is not pinched.
Note:
1) Power fluctuation or low voltage
could result in incorrect drainage.
2) Make sure that DIP switch #2 of
DSW3 on the relay board of CM25 is
set to the “OFF” position to enable the

INSPECTION & MAINTENANCE
! WARNING: When performing any maintenance and/or
troubleshooting, make sure that all electrical power is off. This means
before service, unplug the unit from the electrical outlet or if
permanently wired, make sure the circuit breaker is in the off position.
1) Remove any dirt or debris which may collect in the bottom of the reservoir tank.
2) On a monthly basis, check the condensate drain hose for kinks, blockage or
any other damage that may obstruct condensate pump from draining properly.
3) Always replace the fan motor cover to keep electrical parts free of dust, dirt and
any other foreign material.
Testing Drain Tank Overflow Switch
This safety feature will stop the unit operation if the pump malfunctions. To test
the drain tank overflow switch, pinch the drain outlet hose and pour water into
the reservoir inlet drain hole. Continue to fill the reservoir until rising water lifts
the overflow switch and stops the operation. Self-diagnostic code “E07” is
displayed on the supplied wall mounted controller and a buzzer (pattern 3)
turns on. Only a buzzer turns on for the field supplied millivolt wall thermostat.
Note: Before testing, make sure that DIP switch #2 of DSW3 on the relay board of
the unit is set to the OFF position to enable the internal condensation removal pump.
If the unit continues to operate when the reservoir is full, check your installation
procedure. After testing is completed, release the drain outlet hose and the
condensate pump will empty the reservoir. Make sure the drain inlet hose is
installed into the inlet drain hole of the pump reservoir. To clear self-diagnostic
code and buzzer, press RESET button for the wall mounted controller or reset
power from the circuit breaker for the millivolt wall thermostat.
