3. Description

• The pumps of E-ZW-series are fitted with a robust single-phase TEFC electric motor.
• The most important seal is a mechanical seal between motor and pump– body and also a rotating mechanical seal.
• All units have a 10m power supply cable with plug for 230V 50Hz single-phase.
• Other voltages are possible on demand. Please note the data printed on the type-plate.

• This pump must be connected to an earthed outlet.
• Do not lower or lift the pump by means of the power cable.
• A damaged power cable must be replaced immediately by a qualified electrician. Danger of personal injury by electrical shock if operated with a damaged cable!
• If the pump is connected to an electric installation where an earth-leakage circuit breaker (CB) is used as an additional protection, this circuit breaker must trip out when earth fault current exceeds 30mA.

• Any operation of the pump next to a swimming pool or garden pond is only permitted if the unit is installed in accordance to local legislations.
  It is strictly forbidden to swim while using the pump in the swimming pool.
• If in doubt consult a qualified electrician.

4. Installation and commencement of operation

Before starting any work on the pump/motor make sure that the electric supply has been switched off and that it can not be accidentally switched on.

Before installing and starting please check the waste water lifting unit for possible damages (i.e. during transport) to prevent personal injury by electrical shock.

If the pump is installed stationary inside a shaft, the minimum dimension should be 450 x 450 x 450mm. The build-on float switch (version A) could be locked at a shaft wall. The float switch mounted at the pump must be able to work free. As the water level rises, the float switch does too, the pump starts working until a certain level is reached, when the float switch stops automatically. The height for turning on/off can be varied by displacing the float switch cable in the fastening eye.

The function of the float switch can be verified by raising and lowering of the float switch. Pumps without float switch will start immediately upon placing of the plug in the outlet.

To avoid damages of the pump hydraulics and seals, the pump must not run dry! Also it is forbidden to use the pump against a closed valve.

5. Maintenance / Service

Always disconnect from power before servicing!

Service and repair at electrical parts of the pump (cable, motor) has to be done by authorised service- companies or producer.

In case of very low temperatures and in any case before the first frost the pump must be removed from water. Empty the pump and store it in a place where it is protected from frost.

Service and repair at electrical parts of the pump (cable, motor) has to be done by authorised service- companies or producer.

The servicing of the pump consists of cleaning and checking the pump body. The strainer may dismount through removing the screws at the rear side of the pump. Complete this in reverse order.

A possible wear of the impeller (i.e. through abrasive media) may result in the damaging of the mechanical seal. The checking of the mechanical seal and the motor should be done by a qualified electrician.

In case of very low temperatures and in any case before the first frost the pump must be removed from water. Empty the pump and store it in a place where it is protected from frost. We recommend to switching on the pump for a very short time to avoid a jamming of the mechanical seal every 2 month.
