WARNING:
Read all safety precautions and instructions. Failure to obey the safety precautions and instructions might cause an electric shock, a fire, and/or severe injuries. Keep all safety precautions and instructions for future use.

Resistance

• The maximum temperature of the pumped liquid should not exceed +35 ℃ in continuous oper-ation.
• The pump must not be used to pump flammable, gassing, or explosive liquids. The transport of aggressive fluids (acids, bases, etc.) as well as of abrasive substances (e.g., sand) must be avoided.
• To avoid damage caused by dry running, we strongly recommend our customers to use one of our automatic pump controls that prevent the pump from running dry.

Intended use and field of application

• For watering green spaces, vegetable patches, and gardens
• For operating lawn sprinklers
• With pre-filter for withdrawing water from ponds, streams, rain barrels, rainwater tanks, and fountains

Media to be pumped
For pumping clear water (sweet water), rain water, or suds (slightly soiled water)

Operating instructions
We recommend the use of a prefilter and a suction set with suction hose, suction strainer and a check valve to prolong the suction process and to avoid damaging the pump with stones and foreign bodies.

Technical specifications

Electrical connection

• The electrical connection is made to an earthed socket 230 V ~ 50 Hz. Fuse min. 10 A.
• The device has an ON/OFF switch with which it is switched on and off. The inner control lamp of the switch is lit when the motor is switched on.
• The motor is protected from overcharge and blockage with the help of the built-in thermal motor protection. When overheated, the pump motor is automatically switched off by the thermal pro-tection; after cooling down, the pump automatically re-starts.

Suction line

• Connect a suction hose (plastic hose min. ¾″ spiral reinforced) directly or with a thread nipple to the suction connection (1″ internal thread) of the pump.
• The suction which is used should have a suction valve. In case the suction valve cannot be used, a check valve should be installed in the suction line.
• Position the suction line from the water withdrawal to the pump on a rising gradient. Avoid plac-ing the suction line higher than the pump height; air pockets in the suction line would slow down and impede the suction process.
• The suction and the pressure line must be installed in such a way, that they do not exert any mechanical pressure on the pump.
• The suction valve should lie deeply enough in the water, so that a drop in the water level cannot lead to the pump running dry.
• A leaking suction line prevents the suction of water due to air intake.
• Avoid sucking in foreign particles (sand, etc.) and, if necessary, install a prefilter.

Pressure line connection

• The pressure line (should be at least ¾″) must be connected directly or via a thread nipple to the pressure line connector (1″ internal thread) of the pump.
• With the suitable screw joints a ½″ pressure hose can be used. Correspondingly the pump out-put is reduced due to the small pressure hose.
• During the suction process the shut-off devices (valves, spray nozzles) in the pressure line must be completely open so that the air in the suction line can escape freely.

Initial operation

1. Place the device on a level and solid surface the temperature of which does not exceed 40 ℃. On the installation site, place the pump horizontally so that the bearing can operate correctly. Screw the pump to the surface.
2. Install the suction line so that it is ready for use. The suction hose should not be narrower than the suction connection. If the suction height exceeds 4 m, use a suction line with a larger diam-eter.
3. Connect to mains.
4. Fill in the pump with water at the pressure port.
5. During the suction process, the shut-off devices (valves, spray nozzles) in the pressure line must be completely open so that the air in the suction line can escape freely.
6. Depending on the suction height and the air quantity in the suction line, the first suction process can take approx. ½ min–5 min. With longer suction periods of sucking in, new water should be refilled.
7. If the pump is removed after its use, do not forget that it must be refilled with water before you operate the pump again and before restarting and connecting it again.

Maintenance hints
The machine is largely maintenance-free. However, for a long working life and continuous operation, we recommend regular checking and proper care.

• Attention! Before every maintenance, the pump must be switched off; to do so, disconnect the pump from the power supply.
• Before a long period of non-use, the pump must be rinsed thoroughly with water, completely emptied, and stored in a dry environment.
• In case of frost danger, the pump must be completely emptied.
• After long non-operation periods, check if a proper turning of the rotor takes place; to do so, shortly switch the pump on and off.
• In case the pump is blocked, connect the pressure line to the water line and remove the suction hose. Open the water line. Switch on the pump for several times for approx. 2 s. Thus, blockages can be cleared in most cases.

Pump control for domestic waterworks
Pressure switch EDWC2001
The pressure switch automatically controls the start and stop of the pump depending on the pressure drop (opening of the water faucet) and water flow stop (closing the water faucet). The pressure switch stops the pump if no water is conveyed (protection against dry running).

Technical specifications

Function

• Starts and stops the pump automatically.
• It protects the pump against damage caused by dry running.
• The pressure switch starts the pump for 15 s if it is connected to the voltage source. If the pres-sure in the line system drops, the pump is restarted. In the case of conventional systems with pressure switch and pressure tank, the pump stops running if a certain pressure level is achieved. In contrast to this, the pressure switch stops depending on the flow rate. In doing so, it delays switch-off of the pump for a few (7–15) seconds to minimise the number of pump starts.

LED display

• Upper (1st) LED (alarm) blinks: unit off due to lack of water (protection against dry running) –press “restart” to start the unit again.
• Middle (2nd) LED blinks: pump switched on.
• Lower (3rd) LED blinks: switch has voltage.
• Restart (reset) button: restart unit.

Troubleshooting
