Unspecified use, modification of the pump or use of parts that have not been
tested and approved by the manufacturer can cause unforeseeabledamage!
3.2 General safety instructions
– When using this pump observe the follow- ing safety instructions to exclude
the risk of personal injury or material damage.
– Follow the legal guidelines or accident prevention regulations for use of
submersible pumps.
– When the pump is being used in swimming pools and garden ponds and in the
protected areas around them, the regulations must be observed in accordance
with DIN VDE 0100-702 and -738.
All local regulations pertaining 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 the swimming pool or garden pond)!
The following residual risks do principally exist when operating submersible
pumps and can not 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: Hot water!
If the shut-off pressure of the pressure switch cannot be reached due to poor
pressure conditions or a defective pressure switch the water can heat up
within the pump as a result of internal circulation. Through this the pump and
the connection lines can become damaged or leaky, allowing hot water to
escape.
Danger of scalding!
- Do not operate the pump against a closed pressure line for longer than 5 minutes.
- Unplug the pump and allow to cool. A specialist must check the system to make sure it is in perfect working order before it can be used again.
Danger!
Risk of electric shock!
Do not touch the plug with wet hands! To unplug 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 can not get into the fluid to be pumped.
Always unplug before servicing the pump.
Risk of electric shock from pump faults!
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 hazard 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:
–alarm or
– collection tank with monitoring. The manufacturer is not liable for any
damage caused by:
– improper use of the pump;
– overloading of the pump through continous operation;
– 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).
Assembly and Installation
4.1 Connecting the discharge line
-
For selection of the largest discharge line diameter: cut the smaller (9) attachment off the multi-adapter.
Note:
The best pump capacity is achieved through selection of the largest discharge line diameter. -
Place the non-return valve (11) in the discharge port (12). The non-return valve must open in the direction of the arrow (label ‘UP’ on the non-return valve must point to the multi-adapter).
-
Screw the multi-adapter (10) on to the discharge port (12).
-
Slide the discharge line over the multiadapter (10) and secure with a hose clamp.
4.2 Fixing the float switch cable
Note:
Fix the float cable such that the distance between the cable holder and the
float switch is at least 100 mm.
- Clip the float switch cable as illustrated in the cable holder (13). Ensure that the cable is secured in the cable holder in such a way that it cannot slip.
Caution!
The float switch cable may be damaged.
Never pull on the float switch cable to change its position in the cable
holder! Remove the cable from the cable holder andclip it back in the cable
holder in the desired position.
4.3 Installation instructions
-
Space required: approx. 50 x 50 cm.
In order for the float switch to function properly it must be able to move freely. -
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 foreignobjects.
If necessary place the pump on a support surface. -
Ensure sufficient upright stability.
Risk of electric shock from severed cables!
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
- 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.
- 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.
- Before operating the pump again ensure that the pump line has been completely emptied. When doing so vent the pump if necessary.
Operation
5.1 Switching ON and OFF
After you have connected the pump to the mains it will be switched on (14) and
off (15) automatically by the float switch. The point in time at which
switching occurs depends on the water level.
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!
The pump may run dry and thereby be damaged.
The float switch must always be able to move up and down to allow the pump to
be switched on and off.
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.
Pump Care
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 Routine care
For the pump to function perfectly at all times routine care is required. This
also applies if
the pump is not switched on for extended periods of time (e.g. during
operation in soakaways).
Cleaning the pump
- Rinse pump with clean water. Remove persistent marks, e.g. algae deposits, with brush and dishwashing liquid.
- 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 accesso- ries as both always contain water!
- If there is a danger of frost disassemble pump and accessories and store in frostfree conditions.
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?).
– After cooling the pump will switch ON again. -
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. -
Non-return valve incorrectly installed.
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 unrestrictedly.
