6. Commissioning
When three-phase AC is used, the sense of rotation must be checked by switching the
motor on briefly. The motor must rotate in the sense indicated by the arrow on the fan
cover.
Checking the sense of the rotation is especially important with three-phase motors as the
pump may also turn in the wrong direction. If this is the case, interchange two of the
phases and repeat this check.
7. Servicing / maintenance
In the event of imminent frost in winter, the water level in the pool must to be lowered to
the bottom edge of the jet housing to allow for emptying of the suction and discharge lines.
It is recommended to remove the pump during the winter season and to store it in a dry
room.
8. Defects
The jet pump is equipped with a stuffing box for shaft sealing. If water leaks out
permanently under the pump, the stuffing box must be replaced.
To dismantle the pump, proceed as follows:
Switch off the pump and disconnect safely from the mains. Replacement should only be
effected by a specialist. Detach the pump, which is connected to the suction line by means
of a threaded union and to the pressure line by means of a rubber elbow, from the jet
housing and dismantle in compliance with the separate fitting instructions, replace the
mechanical seal and refit in reverse order.
