side of the sensor chamber check for debris between the sensor plates. Cle-
an gently with a soft cloth or Q-tip (fig.11). Do not scratch sensitive surfaces.
Inspect the inlet tube for dirt and blockages and clean if required. Clean the
sealing surface and re-assemble the filter chamber onto the pump. Inspect
the discharge tube for blockages and kinks. Inspect the breather tube for
positioning and obstructions.
Evaporator / Coil Cleaning
When using evaporator cleaning agents, drain discharged liquid into a se-
parate container and flush with clean water. Do not allow cleaning agents
and dirt to drain into pump.
Testing
On new installations, flush installation debris through condensate system
into a bucket, before connecting the pump. If possible via the condensate
collection tray to check also the water drain route. Use a wash bottle if pos-
sible as these are more controllable. The pump should begin to pump until
all, but approximately 12mm / 1/2“ of water is left remaining.
FILTERING
The filter fitted is to prevent large debris such as fibres, scale and slime from
blocking the pump mechanism and tubes. The filter is removable and was-
hable. It extends the life of the pump and should be carefully fitted (fig. 10).
On sealed and filtered air flow systems in clean environments, where clean
condensate is produced, the filter may be removed providing the system is
flushed through first. If in doubt keep the filter fitted.
TROUBLESHOOTING
Pump not operating or operating intermittently:
• Check supply fuse
• Check the filter (see inspection and maintenance)
• Check discharge tube for blockages
• Check tube connections are secure and water tight
See Note 2
Water overflowing or leaking:
• Check the pump is secure and level
• Check discharge tube for blockages
• Check tube connections are secure and water tight
• Check supply fuse
• Check the filter (see inspection and maintenance)
Note 2
The pump motor is protected by an automatic self re-setting thermal over-
load. This will cause the pump to stop if the discharge tube is blocked or
debris built up on the sensor plates causing the pump to pump air. Shut Off
power for 30 minutes to allow to cool. Perform full service routine and test.
If problems still occur, replace complete pump.
