Connecting a hose to the pump when using a 1″, 1 ¼″ or 1 ½″ hose:

1. Screw the G 1 ½ pump connecting piece onto the connection nozzle.

   ---

   

2. Push the hose clamp onto the hose.

3. Push the hose onto the G 1 ½ pump connecting piece and fasten it with a hose clamp.

4. Push the connection nozzle into the Quick-Connect.

   ---

1. Screw the G 1 threaded connection onto the connection nozzle.

   ---

   

2. Fit the special accessory G 1 pump connecting piece(6.997-359.0 pump connecting piece G 1 (33.3 mm) incl. check valve - not included in the scope of delivery) onto the G 1 threaded connection:

Erecting/immersing the pump:

1. Insert the height adjustment of the float switch into the lock.

   ---

   

2. Place the pump securely on solid ground in the pumped liquid or immerse it via a rope attached to the carrying handle.

   Note

   The suction area must not be blocked by soiling. If the ground is muddy, place the pump on a brick or similar. Make sure that the pump stands level. Do not carry the pump using the cable or hose.

1. If the fluid level is low, any sucked-in air, or air present in the pump, may escape via the automatic venting device. Liquid can also leak along with air.

   If the pump has problems priming when the fluid level is low, unplug and plug in the mains plug repeatedly to assist the priming process.

The filter basket can be operated in 2 positions.

---

	Waste water and clear water delivery. We would recommend this filter basket position at the start of the pumping process, since on this occasion the pumping capacity is at its greatest.
	Flat vacuuming. In this filter basket position, flat vacuuming is possible up to 1 mm residual fluid height in manual operation.

1. Put the pump on the ground.

2. Clamp the pump between your feet and take hold of the carrying handle.

3. Unlatch the filter basket by turning the handle to the right.

4. Move the filter basket into the required position.

5. Lock the filter basket in place by turning the handle to the left

1. Set the float switch using the height adjustment, and the cable length between the float switch and the lock.

   Note

   When the pump is operated unattended, always set the float switch to the uppermost position in order to ensure that the pump can switch off reliably.

   ---

   

   When the float switch is set to the lowermost position, set the cable length between the float switch and the lock to 2.5 cm, see marking on the cable.

   ---

   

2. Move the filter basket into the "Waste water and clear water delivery" position, see chapter Adjusting the filter basket.

3. Plug the mains plug into the socket.

   Note

   In automatic mode, the float switch controls the pumping process automatically. The pump switches on as soon as the float switch reaches the switch-on height caused by the rising fluid level.

   The pump switches off when the float switch reaches the switch-off height caused by the sinking fluid level. The float switch must be able to move freely.

   Note

   The switching heights vary depending on:

   • Position of the float switch.

   • Cable length between the float switch and lock.

     The cable length must be at least 2.5 cm. We would recommend retaining the set cable length. For information on the switching heights, see chapter Specifications.

1. Fasten the float switch in the lock pointing upwards.

   ---

   

2. Move the filter basket to the desired position depending on the fluid level (see chapters Specifications and Adjusting the filter basket).
