(10) Power supply wiring, in order to avoid leakage of condensate pump, please
connect the alarm signal line and the "Normally Closed" and "Normally Open"
signal terminals according to the requirements of different working conditions
(as shown below).
Please pay attention to distinguish the power cord from the signal line,
incorrect wiring will cause damage to the condensate pump. Ensure the
voltage is consistent with pump.
(11) Pour some water into the evaporator tray to check whether the tray leaks and the
condensate pump works normally.
WARNING
1A
B
C
Pump runs
all the time
1. Installation is not horizontal
2. There is sludge inside tank
Problem Cause Action
Pump makes
loud noise
Pump can’t
start working
Adjust the tank make it level
Clean the inside of tank and probe surface
1. The water is siphoning back
in the pump
Check whether the outlet pipe is lower than
pump thus result in siphoning, raise the
condensate pump position
1. Installation is not horizontal
2. The power can’t reach pump
3. The voltage isn’t correct
1. Adjust the tank, check water level
2. Check power supply
3. Check the voltage
7. Troubleshooting
Note: Proper use and maintenance can improve the life of pump. We suggest to check
and clean the condensate pump before seasons changing or next year using.
