  – Follow the legal guidelines or accident prevention regulations for using submersible pumps.
• When the pump is being used in swimming pools, garden ponds and in the protected areas around them, the regulations must be observed in accordance with IEC 60364-7-702.

All national regulations relating to the safe operation of submersible pumps must also be followed.

- The pump must be protected by a residual current device (RCD) with a trip current of max 30 mA.

General danger!

Do not operate the pump if anyone is in contact with the pumping media (e.g. in a swimming pool or garden pond)!

The following residual risks essentially remain when operating submersible pumps and cannot be fully eliminated – even by employing safety devices.

Danger from the environment!

Do not use the pump in hazardous locations or near inflammable liquids and gases!

Danger! Risk of electric shock!

Do not touch the plug with wet hands! To disconnect, always pull on the plug, not the power cable.

Connect only to an earthed outlet that is properly installed, earthed and tested. Mains voltage and fuse protection must correspond to those stated in the 'Technical Specifications'.

Always lift and transport the pump by the handle, never by the power cable or discharge hose.

Extension cables must have sufficient conductor cross sections. Unroll cable reels fully. Do not buckle, squeeze, drag or drive over power cable or extension cables; protect from sharp edges, oil and heat.

Place extension cable so that it cannot get into the fluid to be pumped.

Always unplug before servicing the pump.

Risk of electric shock from pumps!

Before each use, check the equipment - especially the power and extension cables, power plug and float switch - for possible damage. Risk of fatal electric shock!

Do not attempt to repair the pump yourself!

When repaired inexpertly, there is a risk of liquid entering the electrical parts of the pump.

Caution!

To avoid water damage, e.g. flooded rooms, caused by pump malfunctions or defects: provide for suitable safety measures such as the following:

• a l a r m o r
  – collection tank with monitoring.

The manufacturer is not liable for any damage caused by:

• improper use of the pump;
  – failure to operate and store the pump in a frost-free environment;
  – unauthorised modification of the pump (repairs to electrical equipment may only be carried out by qualified electricians!);
  – use of spare parts which have not been tested and approved by the manufacturer; or
  – use of unsuitable installation materials (fittings, connection lines etc.).

Suitable installation materials:

– pressure-resistant (min. 10 bar)
- heat-resistant (min. 100°C).

4. Assembly and Installation

4.1 Connecting the discharge line

Connecting thread details: see Technical Specifications.

Note:

The optimum pump capacity is achieved by selecting the largest discharge line diameter.

4.2 Fixing the float switch cable

- How the float switch cable is fixed to the device depends on the particular device model. If necessary, insert the float switch cable in the cable clip of the handle.

The following illustration shows the fixed float switch cable.

Technical line drawing of electrical components with magnified views of cable connections (no text or symbols)

Caution!

The float switch cable may be damaged. Never pull on the float switch cable to change its position in the cable holder!

4.3 Installation instructions

• For the float switch to function properly, it must be able to move freely.
  Space requirement for DP 18-5 SA, DP 28-10 S Inox: approx. 60 cm x 60 cm Space requirement for SP 24-46 SG, SP 28-50 S Inox: approx. 70 cm x 70 cm.
• Submerge the pump to no more than the maximum immersion depth specified in the technical data.
• Install the pump such that the suction inlets cannot be blocked by foreign objects. If necessary place the pump on a support surface.
• Ensure sufficient upright stability.

Risk of electric shock from severed es!

Do not lift or transport the pump by the cables or the discharge hose! The cables and the discharge hose are not designed to withstand the tensile stress produced by the weight of the pump.

4.4 Installing the pump

1. Submerge pump at a slight angle to avoid creating an air cushion on the underside, which would prevent priming. Once the

pump is submerged, it can be placed upright.

1. Lower pump to the bottom of the fluid container.

Use a strong rope fastened to the lifting eye to lower the pump.

The pump can also be operated when suspended by a rope.

1. Before operating the pump again, ensure that the pump line has been completely emptied.

5. Operation

5.1 Switching ON and OFF

After you have connected the pump to the mains, it will be switched on (9) and off (10) automatically by the float switch. The point in time at which switching occurs depends on the water level.

9 10 ON OFF

Adjusting the ON and OFF times for the pump

The position of the float switch cable in the cable holder can be changed. The time interval between pump switch-on and switch-off is thereby adjusted:

• 'Short' float switch cable: ON and OFF positions are close together.
• 'Long' float switch cable: ON and OFF positions are far apart.

Caution!

Attach the float cable so that the OFF position is at least 150 mm above the base of the pump. The pump may run dry and thereby be damaged.

Caution!

The float switch must always be able to move up and down to allow the pump to be switched on and off.

ENGLISHen

Caution!

The pump must not be activated more than 20 times an hour, as this could cause the motor to overheat.

Danger from faulty pump!

Take appropriate measures to ensure that pump faults do not cause consequential damage through flooding of rooms. This must be ensured, for example, through installation of an alarm system or a reserve pump.

Danger!

Do not let the pump run against a closed pump line.

5.2 Minimum water level

Continuous operation:

The pump must be completely submerged for continuous operation to take place.

Restricted operation:

Only restricted operation is possible if the pump is not fully submerged. Note the following restrictions:

Risk of material damage from dry ning of pump!

The pump can overheat and become damaged as the cooling function of the pumped medium is reduced. The thermal switch will react.

• Suction operation for a short period only (2-3 mins).
• Monitor the pump's operation during suctioning.

5.3 Pump capacity curve

The pump capacity curve indicates the flow volume, depending on the delivery head.

6. Device care, maintenance

Danger!

Unplug before maintaining or cleaning.

Repair and maintenance work other than described in this section should only be carried out by qualified specialists.

6.1 Regular care

Regular care is required for the pump to function perfectly at all times. This also applies if the pump is not switched on for extended periods of time (e.g. during operation in soakaways).

Cleaning the pump

1. Rinse pump with clean water. Remove persistent marks, e.g. algae deposits, with brush and dishwashing liquid.
2. To rinse the inside of the pump: dip pump into a container of clean water and switch on briefly.

6.2 Pump storage

Caution!

Frost damages the pump and accessories as both always contain water!

- If there is a danger of frost, disassemble pump and accessories and store in frost-free conditions.

6.3 Device maintenance (only for SP 28-50 S Inox, DP 28-10 S Inox)

Caution!

Lubricant may leak from the pump if the seals are defective, causing contamination of the liquid being pumped.

Although the lubricant contained in the submersible pump for dirty water is non-toxic, it can alter the water properties.

Danger!

Maintenance work must only ever be carried out by qualified, specially trained staff. After 4,000 to max. 8,000 hours of operation, and in any case at least once a year, the quantity and quality of the oil in the oil reservoir must be checked.

7. Troubleshooting

Danger!

Prior to all servicing:

Unplug.

7.1 Troubleshooting guide

Pump does not run:

• No mains voltage.
• Check cables, plug, outlet and mains fuse.
• Mains voltage too low.
• Use an extension cable with sufficient conductor diameter.
• Motor overheated; motor protection relay tripped.
• Eliminate the cause of overheating (pump blocked by foreign objects?).
• Float switch does not switch pump ON when water level rises.
• Make sure the float switch can move unrestrictedly. If, despite sufficient mobility of the float switch, the pump does not switch ON: send the pump to the service centre in your country.

Motor hums, but does not start:

- Pump blocked by foreign objects.

– Clean impeller.

Pump runs, but does not pump properly:

• Delivery head too high.
- Observe max delivery head (see 'Technical Specifications').
• Discharge hose kinked.
– Straighten discharge hose.
• Discharge hose leaky.
- Seal discharge hose; tighten screw fittings.

Pump runs very noisily:

• Pump is sucking air.
• Ensure there is a sufficient water supply.
  – Foreign objects are present (clean pump).
• Manual mode has been set (shallow water suctioning).
• Hold pump at an angle when submerging.

Pump runs continuously:

- Float switch does not reach cut-out position.

- Make sure the float switch can move freely.
