Explosive, flammable, aggressive fluids or substances detrimental to health as well as salt water must not be pumped.
This pump is not suitable for commercial or industrial use.
Modification of the pump or use of parts not approved by the manufacturer is not permitted.
Any use other than the use specified above may cause unforeseeable danger!
4.2 General Safety Instructions
Children, juveniles and persons not familiar with the instructions are not permitted to operate the pump.
When used in swimming pools and garden ponds and within their range of protection, the regulations of DIN VDE 0100 -702, -738 or applicable local regulation must be observed.
When used as domestic water supply any applicable local regulations pertaining to water supply and waste water disposal, plus DIN 1988 (where applicable) have to be observed.
The following residual risks do principally exist when operating pumps and pressure vessels and can not be fully eliminated - even by employing safety devices.
Hazard generated by ambient conditions!
- Do not expose to rain. Do not operate in damp or wet 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 direct water jet directly against the pump or other electrical parts! Risk of fatal electric shock!
- Do not touch the plug with wet hands! To unplug always pull on the plug, not the power cable.
- The earthed outlet or the plug connection to an extension cable must be located in an area safe against flooding.
- Use only extension cables of sufficient lead cross section (see
"Technical Specifications"). Completely unroll cable reels.
- Do not buckle, squeeze, drag or drive over power cable and extension cables; protect from sharp edges.
-
Place extension cable so that it cannot get into the fluid to be pumped.
Unplug: -
prior to all servicing;
- when persons are in the swimming pool or garden pond.
Danger by pump failures!
If you notice transport damage while unpacking, notify your supplier immediately. Do not operate the pump!
- Before each use check the pump, especially the power cable and plug for possible damage. Risk of fatal electric shock!
- A damaged pump must be workmanlike repaired before it can be used again.
- Do not attempt to repair the pump yourself! Only trained specialists are permitted to service or repair pumps or pressure vessels.
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 continuous 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^ ).
5. Prior to Operation
The pump is easily assembled and connected.
If in doubt, contact your specialist supplier or a qualified electrician.
5.1 Installation
- The pump must be placed on a plane and level surface, suitable of bearing the weight of the pump fully filled with water.
- To avoid vibrations the pump should be placed on an elastic base.
- The installation location should be well vented and protected from atmospheric exposure.
- When operated at garden ponds and pools the pump must be set up safe against flooding and safeguarded against falling into the water. Any additional legal requirements are to be observed.
5.2 Connecting the Suction Line
i Note:
Possibly further accessories may be required for connection (see "Available Accessories").
Caution!
The suction line needs to be installed in such manner that it does not exert mechanical force or distortion to the pump.
Caution! When a
When pumping contaminated fluids install a suction strainer to protect the pump from sand and dirt.
i Note:
A check valve is recommended to prevent water backflow when the pump is turned off.
- All screw fittings must be sealed with thread sealing tape; leaks cause the priming of air, which reduces or completely prevents the priming of water.
The suction line should have an inner diameter of 1^ (25 mm) minimum and must be kink and vacuum resistant. - Keep suction line as short as practical, as with increasing length the pump capacity is reduced.
- The suction line should ascend towards the pump to prevent air locks.
- A sufficient water supply must be ensured, the foot valve at the end of the suction line must be submerged in water at all times.
5.3 Discharge Port
i Note:
Possibly further accessories may be required for connection (see "Available Accessories").
Caution!
The discharge (or pressure) line needs to be installed in such manner that it does not exert mechanical force or distortion to the pump.
- All screw fittings should be sealed with thread sealing tape to prevent leakage.
- All parts of the pressure line must be resistant to internal pressure.
All parts of the pressure line must be installed in a workmanlike manner.
Danger! Improper installation and use of parts not resistant to internal pressure can cause the pressure line to break during operation. Risk of personal injury by liquid spurting from the line under high pressure!
5.4 Connection to a Pipe System
A stationary installation (e.g. in an indoor domestic water system) is also possible.
- To reduce vibrations and noises the pump should be connected to the pipe system with flexible tubing.
5.5 Connection to AC Power
Danger! Risk of electric shock! Do not operate the pump in wet environment and only under the following conditions:
- Connect only to an earthed outlet that is properly installed, earthed and tested.
- Mains voltage and fuse protection must correspond with the requirement stated in the "Technical Specifications".
- When operated at pools, garden ponds and similar locations, the pump must be protected by a residual current operated device (RCD, 30 mA) (DIN VDE 0100-702, -738 or equivalent applicable local regulations). We recommend the use of RCD's as a general precaution for personal protection.
- When operating the pump outdoors the electrical connections must be splash-proof; the connections must not be placed into water.
Use only extension cables of sufficient lead cross section (see "Technical Specifications"). Completely unroll cable reels.
5.6 Filling the pump and priming
Caution!
After installation, loss of water or priming of air the pump needs to be filled with water. Starting the pump without water causes damage!
i
Note:
The suction line does not need to be filled, the pump is self-priming. However, depending on length and diameter of the suction line it may take some time until pressure has built up.
-
Remove the water filler plug, complete with gasket.
-
Slowly pour in clear water, until the pump is filled.
-
To reduce the time needed for priming you can also fill the suction line.
-
Replace the water filler plug, complete with gasket.
-
Open pressure line (open tap or spray nozzle) for any air to escape during priming.
-
Start pump (see "Operation").
-
Turn pump OFF when water runs out steadily.
6. Operation
Pump and suction line must be connected and filled (see "Prior to Operation").
#
Caution!
The pump must not run dry. Ensure there is always sufficient pumping medium (water) available.
- If the motor does not start, no pressure is built up or similar effects are evident, switch the pump OFF - and try to resolve the fault (see "Trouble Shooting").
