GB
®
DRENOX range pumps have a built-in thermal overload with automatic reset.
Further protections are not required.
®
DRENOX range three phase pumps can be protected by using a magneto-thermic motor protector or a contactor with thermal
relay; in both cases they have to be rated conforming to nominal power showed on motor plate.
Eventual electric float switch must be connected to auxiliary connector buckles.
Water head and delivery are terribly effected by wrong rotation of shaft of pump motor.
Clock wise rotation is correct ( upside view of pump ).
When starting the pump, motor will ungergo an anti-clock wise back-kick.
In this case test is positive; on contrary case, please disconnect pump from network and inverse two phases.

DANGER
Electric shock risk
®
range pumps operate in normal conditions.
POSSIBLE CAUSE
1) No electric current supplying.
2) Incorrect plugging in .
3) Circuit-breaker come into operation.
4) Impeller blocked.
5) Motor or capacitor damaged.
1) Filter obstructed.
2) Non return valve blocked.
1) Filter partially obstructed .
2) Delivery pipe partially obstructed.
3) Impeller worn off.
4) Anticlockwise rotation ( three phase
version).
1) Solids obstruct impeller.
2) Too warm liquid.
3) Motor broken.

Before doing any operation, make sure pump is
disconnected from electric current network.
Power cord must be replaced by manufacturer or by
Customer service, using special tools.
REMEDY
2) Verify presence of electric current supply and
plug in.

Please call electrician in case circuit-breaker
comes again into operation.
4) Remove obstacle.
5) Call dealer.
1) Clean filter.
2) Clean or replace valve.
1) Clean filter.
2) Remove obstacles.
3) Replace impeller.
4) Inverse two phases.
1) Remove obstacles.
3) Call dealer.
