CONDENSATE PUMP KIT 53900410
This kit is for use on 539 series IMPULSE and 968 series CWR units for the removal of condensate where gravity drain is
not practicable or desirable.
The pump is capable of overcoming a resistance equivalent to 5 metres lift.
The sensor is arranged so that residual condensate in the sump is kept to a minimum.
The kit includes an overflow protection circuit, which will prevent further cooling and condensate production if a high
condensate level occurs.
