This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of ex-perience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
If the power cable for this equipment is damaged, it must be replaced by the manufacturer or its after-sales service or similarly trained per-sonnel to avoid danger.

Proper use

The equipment you have purchased is designed to pump water with a maximum temperature of 35 °C. This equipment must never be used for other liquids, especially not for engine fuels, cleaning agents and other chemically-based products!
Before you use the pump, clarify any possible special conditions which need to be fulﬁ lled for the installation!
For example, additional safety measures may be needed if damage to property could result from a power failure, soiling or a defective gasket. Examples of such safety measures:
Pumps running in parallel on a separately protec-ted power circuit, moisture sensors for switching oﬀ the pumps, and similar safety arrangements. Be sure to consult a professional plumber if you have any doubt.
The equipment can be used wherever you want to move water, e.g. in the house, in the garden, and for many other applications. It must not be used to operate swimming pools!
If you want to use the equipment in bodies of wa-ter with a natural, muddy bottom, place the equip-ment in a slightly elevated position, e.g. on bricks.
The equipment is not designed for continuous operation, e.g. as a circulating pump in a pond. In this case the equipment’s anticipated life will be greatly shortened because the equipment was not designed for continuous loading.
The equipment is to be used only for its prescri-bed purpose. Any other use is deemed to be a case of misuse. The user / operator and not the manufacturer will be liable for any damage or inju-ries of any kind caused as a result of this.
Please note that our equipment has not been de-signed for use in commercial, trade or industrial applications. Our warranty will be voided if the machine is used in commercial, trade or industrial businesses or for equivalent purposes.
The water may be contaminated by escaping lub-ricating oil/lubricant.

Before starting the equipment

Before you connect the equipment to the mains supply make sure that the data on the rating plate are identical to the mains data.

Installation

The equipment can be installed either:

Stationary with a rigid pipe line or
Stationary with a flexible hose line

The equipment must be fastened to the suspensi-on eyelet with a rope.
The maximum pumping rate is possible only with the largest possible line diameter; if smaller hoses or pipes are connected, the pumping rate will be reduced. If the universal hose connection (Fig. 1/Item 1) is used, it should be shortened (as shown in Fig. 3) to the connection actually used in order not to reduce the pumping rate unnecessarily. Flexible hoses must be fastened to the universal hose connection with a hose clip (not included in the scope of supply).
The non-return valve (Fig. 3/Item 7) prevents the water in the hose ﬂ owing back when the pump is switched oﬀ . The use of the non-return valve reduces the maximum delivery rate.
Water might escape from the ventilation opening during operation.
Note!
When installing, never hang the equipment by the discharge line or by the power cable. The equipment must be hung up by the provided carry handle or suspension eyelet, or it must rest on the bottom of the shaft. To ensure that the equipment works properly, the bottom of the shaft always must be free of sludge and other accumulations of dirt. If the water level is too low, the sludge
in the shaft can quickly dry out and hinder the equipment from starting. It is necessary therefore to check the equipment regularly (carry out trial start- ups).

Mains connection

Danger!
The equipment you have purchased comes with an earthing-pin plug. The equipment is designed for connection to a socket outlet with earthing contact for 220 V ~ 60 Hz. Make sure that the socket-outlet is su ﬃ ciently fused (at least 6 A) and in good working order. Insert the power plug in the socket- outlet and the equipment is ready for operation.

Operation

Starting up

You can put the equipment into operation after you have thoroughly read the installation and ope-rating instructions. Pay attention to the following points:

Make sure that the equipment is set up secu-rely.
Check that the discharge line is fitted correct-ly.
Make sure that the electrical connection is 220 V ~ 60 Hz.
Check that the electrical socket-outlet is in good working order.
Make sure that no moisture or water can ever reach the power connection.
Make sure that the equipment does not run dry.
To switch off the equipment, pull the power plug out of the socket outlet.

Operating mode

ON Manual mode

Autostart level 1: ON point 70 mm
Autostart level 2: ON point 135 mm
Autostart level 3: ON point 188 mm

Mode of operation of the integrated ﬂoat switch

Application 1:
In ON mode the equipment will run continuously and the water can be sucked up down to a level of 40 mm. To prevent dry running, this operating mode is allowed only under supervision. The equipment must be switched oﬀ (pull out the power plug) as soon as no more water is emitted from the discharge line.
Please note:
For the equipment to suck up water in ON mode there must be a minimum depth of 50 mm of water!
Application 2:
The pump can be used in autostart mode for ri-sing water levels. When the preset autostart level is reached, the pump starts automatically. Re-gardless of the selected autostart level, the pump will pump until 70 mm is left and will then continue running on for a further 15 seconds before swit-ching oﬀ automatically.
Please note:
The fact that it switches oﬀ automatically after 15 seconds prevents the pump from running dry for any prolonged period of time. Since the pump continues running, a low amount of noise may be generated if there is no liquid, but this will not lead to any damage to the pump. The water can be sucked up down to a level of 40 mm as a maximum.
Application 3:
The pump can be used in autostart mode where the water level at the beginning is higher than the preset autostart level. Regardless of the selected autostart level, the pump will pump until 70 mm is left and will then continue running on for a further 15 seconds before switching oﬀ automatically.
Please note:
The fact that it switches oﬀ automatically after 15 seconds prevents the pump from running dry for any prolonged period of time. Since the pump continues running, a low amount of noise may be generated if there is no liquid, but this will not lead to any damage to the pump. The water can be su-cked up down to a level of 40 mm as a maximum.
Replacing the power cable
Danger!
If the power cable for this equipment is damaged, it must be replaced by the manufacturer or its after-sales service or similarly trained personnel to avoid danger.

Cleaning, maintenance and ordering of spare parts

Danger!
Always pull out the mains power plug before star-ting any cleaning work.
