If the Rain Water Tank Pump is used in a shallow vessel, e. g. to
empty an inflatable children's pool, the telescopic pipe can be
removed and replaced by the GARDENA Threaded Tap Connector
33.3 mm (G 1) – Art. No. 2902 / 2802. The hose connection
13 mm (1/2"), 16 mm (5/8") or 19 mm (3/4") is made using the
Original GARDENA System or GARDENA Profi "Maxi-Flow"
System threaded hose connectors.
For deeper containers (up to max. 7 m), the pump can no longer
be hung on the telescopic pipe. The pump must then be attached
through a cord connected to the telescopic pipe and submersed
into the container.
The operation of a Micro-Drip-System is possible. Here, the maxi-
mum values stated in the accompanying manual of the Master
Unit 2000 are reduced. With Art. No. 1742, at least 90 l/h must be
taken as otherwise the leakage protection is activated.
