Never work alone. Always wear a hard hat, safety glasses and safety shoes and, if necessary, a suitable safety belt.

Before carrying out welding works or using electrical devices, check to ensure there is no danger of explosion.

People working in wastewater systems must be vaccinated against the pathogens that may be found there. For the sake of your health, be sure to pay meticulous attention to cleanliness wherever you are working.

Make sure that there are no toxic gases in the working area.

Observe the health and safety at work regulations and make sure that a first-aid kit is to hand.

In some cases, the pump and the pumping medium may be hot and could cause burns.

For installations in areas subject to explosion hazards, special regulations apply!

APPLICATION

DANGER!

The pump must never be used when a person is in the water.

Submersible pumps of the MultiDrain series are suitable for pumping wastewater, rainwater, groundwater, seepage water or drainage water with admixtures of up to 10mm grain size.

Use of the pumps is subject to relevant national laws, regulations and local requirements such as:

• Domestic contaminated water and waste water (e.g. EN 12056 in Europe)

• Installation of low voltage systems (e.g. VDE 0100 in Germany)

For non-standard utilisation conditions, further regulations must be observed (e.g. VDE 0100 in Germany, part 701: bathrooms and shower rooms; part 702: Swimming pools and fountains; part 704: Construction sites and part 737: outdoor use).

Temperatures

Motor at the surface: continuous operation S1

The pumped medium must have a temperature of max 40^

The submersible pump is frost-resistant down to -20^ when stored in dry conditions. When installed, however, it must not be allowed to freeze in the water.

Transport

The pump must always be lifted by the handle and never by the power supply cable! The pump should only be lowered into deeper chambers or pits using a chain.

ELECTRICAL CONNECTION

NOTICE! Only qualified electricians may carry out electrical work on the pump, plug or the control unit.

The pump must only be connected to circuits that have been installed properly in accordance with the regulations and are protected with at least 10 A (slow) and RCD-safety switches (30mA).

Current applicable standards (such as EN standards), national regulations (such as VDE in Germany), and the regulations of the local power supply companies must be complied with.

Some types are supplied with an open cable end. To connect to the power supply, a control unit or a nationally approved plug with a protective earth contact must be used.

NOTICE! Never put the mains plug or a free lead end in water! If water gets into it, this can cause malfunctions and damage.

Observe the operating voltage (see type plate)!

The pump is provided with a winding thermostat. In case of unacceptably high temperatures, it switches off the pump to protect it against possible damage. Unacceptably high temperatures may result e.g. from dry running or mechanical or electrical overload.

CAUTION!

The pump is switched on again automatically after cooling down - risk of injury!

For this reason, always disconnect the device from the mains before remedying the fault! In order to do this, unplug from the mains supply or remove the pre-fuses of the pump controls!

Pumps without built-in level control can also be operated automatically through the use of our level controls.

Rotational direction

The rotational direction must be checked before installation! If the rotational direction is correct, the start-up jolt should be in the opposite direction to the rotational direction arrow on the motor housing. The wrong rotational direction is also indicated if the pump performs inadequately when installed, or if loud noises can be heard during operation. If the rotational direction is wrong, 2 phases of the supply cable must be swapped over.

CAUTION!

The start-up jolt can be very forceful.

INSTALLATION

The pump must be installed as shown in the examples. For installations in accordance with EN 12056-4, the pressure pipe must be laid in a loop above the local backflow level and protected with a non-return valve in accordance with EN 12050-4. A correspondingly larger diameter pipe should be used for longer pressure pipelines to avoid pipe friction losses.

The MultiDrain pumps have a vertical discharge branch.

In contrast to pumps with built-in level control, the ON and OFF switching heights of pumps without built-in level control are variable by the use of a separate level control.

NOTICE! If the pump is malfunctioning, part of the contents of the oil reservoir could escape into the pumping medium.

Dimensions of sump

Single installation: 40 × 50 cm

Duplex installation: 40 × 70 cm

NOTICE! The floats of the level control and alarm system are installed so that they are freely movable but not under the inlet. Please observe the minimum distances. The controls must only be installed in a dry and well ventilated room!

MAINTENANCE

Maintenance and inspection of this product must be carried out in accordance with EN 12056-4.

To ensure continued reliability of service, we recommend that you take out a service contract.

DANGER!

Before carrying out any work: Disconnect the pump and the control unit from the mains power supply and take action to ensure that no one else can reconnect them to the power supply.

WARNING!

Check the plug and the mains cable for signs of mechanical and chemical damage. Damaged or kinked cables must be replaced by the manufacturer.

NOTICE! When using a chain to lift the pump, please observe the relevant national regulations regarding accident prevention. Lifting gear must be checked regularly by an expert in accordance with the legal regulations.

Cleaning

The inlet strainer prevents coarse dirt from entering the pump. Regular cleaning of the float and the foot strainer ensures optimum performance and operation.

If the impeller needs to be cleaned due to blocking or clogging, remove the screws on the underside of the pump and then remove the foot strainer.

Tightening torque M_r for A2 screw materials

M6 M_ = 8Nm,

M8 M_ = 20Nm

M10 M_ = 40Nm

M12 M_^* = 70Nm

foot strainer M_ = 3 Nm .

QUICK TIPS FOR REMEDYING FAULTS

Pump does not work

• Check mains current (do not use a pin gauge)
• Fuse faulty = may be too weak (please refer to Electrical Connection)
• Mains supply cable damaged = repair to be carried out by manufacturer only

Pump runs but does not pump

• Empty the pressure pipe or hose to allow the non-return valve to open and the air to escape from the pump housing.

Impeller blocked

• Solids and fibrous matter have become lodged in the pump housing = clean

Decreased pumping performance

• Foot strainer obstructed = clean
• Pump housing obstructed = clean
• Impeller worn = replace
• Wrong direction of rotation (for a three-phase current) = ask a qualified electrician to change 2 phases of the supply line
