Installation variants

A
Installation variants

Variant (a): Water flow only through the filter housing.

  * Pump 1 and 2 either operate in parallel or separately.

Variant (b): Water flow through the filter housing and through an additional satellite filter or skimmer.
Water flows through a satellite filter or a skimmer on inlet 1 to pump 1.
Water flows through the filter housing (inlet 2) to pump 2.

Installation and connection

The use of the pump is only permitted with observance of the specified water quality.

Pool water or salt water can impair the appearance of the unit. Such impairments are excluded from the guarantee.

WARNING
Severe injuries or death due to operation of this unit in a swimming pond. Defective electrical components will electrify the water with dangerous electrical voltage.

Never operate the unit in a swimming pond.

CAUTION
Rotating components in the intake and pressure socket area. Risk of injury when reaching into the sockets.

In particular, observe the following: A unit that has stopped due to overload can start up unexpectedly!

Do not reach into the opening of the intake socket or pressure socket while the power plug is plugged in.
If the sockets are freely accessible during operation, e.g. if no hoses are connected, use a hand guard to secure the sockets. The hand guard is available as an accessory.

NOTE
If the pump is used for conveying excessively soiled water, the impeller unit will be subject to increased wear and will require earlier replacement.

Thoroughly clean the pond or pool before installing the pump.
Install the pump at a raised level above the bottom of the pond. This reduces intake of muddy water.

Avoid direct sunlight on unit components that are not submerged, as they may overheat. If necessary, use a protective cover.

Connect the unit

Connect the pump according to the desired installation variant. (→ Installation variants)
Do not plug the power plug into the socket yet!

Water flow only through the filter housing

Water flow through the filter housing and through a satellite filter or skimmer
C

Installing the unit

D
Installing the unit

Place the pump horizontally on a stable, mud-free surface.
Ensure secure and stable positioning of the pump.
Only operate the pump when it is fully submerged.
The pull rope allows you to simply pull the pump from the water.
- Fasten the pull rope on the bottom filter casing through the round openings and make a knot.

Install the receiver

NOTE
The receiver will be damaged if it is constantly subjected to moisture.

Install the receiver in a moisture-protected location.
If necessary, use a protective cover.

E
Install the receiver

Position the receiver in a flood-protected location at least 2 m from the edge of the pond.
Fasten it to the ground with the ground stake or suspend it vertically using 2 screws.
- Do not operate the receiver while it is in a horizontal position, only operate it in a vertical position with the ground stake intake pointing down.

Do not plug the power plug into the socket yet!

Commissioning/start-up

NOTE
The unit will be destroyed if it is operated with a dimmer. It contains sensitive electrical components.

Do not connect the unit to a dimmable power supply.

NOTE
Prevent the pump from running dry. Otherwise the pump will be destroyed.

Only operate the pump when it is submerged or flooded.

Switching ON/OFF

Switching on: Plug the power plug into the outlet.
- The unit switches on immediately.
Switching off: Pull the power plug from the outlet.

Environmental Function Control (EFC)

When started up, the pump automatically performs a pre-programmed self-test (Environmental Function Control (EFC)). The pump detects if it is running dry / blocked or submerged. The pump shuts down automatically after 60 to 120 seconds if it runs dry/is blocked. In the event of a malfunction, disconnect the power supply and “flood the pump” or remove the obstacle. Afterwards, the unit can be restarted.

Operating functions

The hand-held transmitter allows you to switch pumps on and off remotely and to adjust their power.

Provided there is a line of sight between transmitter and receiver, radio transmission of up to 80 metres is possible.
Before it is possible to operate the unit with a transmitter, it is necessary to register (log in) the transmitter on the receiver. You can register up to 10 transmitters on the receiver.
