5. Assembly/Installation

5.1 Assembly
– Site and shaft for the pump must be frost-free.
– In the case of permanent installation the bottom
of the shaft must be level and free from coarse
impurities (e.g. rubble, earth).
ATTENTION! The pump may not be carried or
hung by the connecting cable or
float. A rope should be used to lower
and locate the pump.
– The diameter of the compressed-air piping (pipe /
hose connection) may not be smaller than the
delivery connection of the pump. To avoid
pressure losses, it is recommended to select a
nominal width greater for the pipe connection.
– To protect against possible reflux from the public
conduit the compressed-air piping is to be fed
over the locally established reflux level (generally
street level) in a bend.
– If the TM pump is permanently installed, a non-
return device (accessory) is required.
– The pipe connections to the pressure pipe
connections of the pump are to be sealed with
Teflon tape.
ATTENTION! Constant leaks in this area may
destroy the built-in non-return
device and screw joint.
– The pump is designed such that it can be fully
submerged in the pumping medium. The level
control for the start-up / cut-out level can be
altered via the free float cable.

ATTENTION! The minimum level (see fig. 1 and
table 1.2.2) may not be fallen short of.

5.2 Electrical connection

Electrical connection should be made
by a qualified electrician. Current
national regulations must be observed
(e.g. VDE regulations in Germany).
– Check the mains current and voltage.
– Ensure compliance with the data on the rating
plate.
– Mains voltage see rating plate.
– Mains fuse: 10 A, time-lag.
– Observe earthing regulations.
– It is recommended that a residual current
operating device to be provided by the
customer be installed for a tripping current of
30 mA (for installation in open air directive!).
– The pump is connected to a socket outlet with
earthing contact, to be provided by the customer.
To connect the pump to a switching device the
earthing-pin plug is cut and the connecting cable
wired as follows:
brown wire to "L1", blue wire to "N", yellow-green
wire to "PE".
– The socket outlet and / or switchbox are to be
installed so as to be flood-proof and in a dry
area.
– Pumps intended for use in or on swimming pools,
garden ponds and similar places must have a
supply cable to the mains which is no lighter than
rubber-insulated flexible cables with identification
symbol H07 RN-F (245 IEC 66) to EN 60335.
– In accordance with EN 60335, submersible
motor-driven pumps with less than 10 m of
connecting cable are only permitted for use within
buildings, in other words not for operation in the
open air.

6. Operation

The pump may not be used to drain
swimming pools if people are in the
water.

6.1 Setting the pump

– The unhindered movement of the float switch must
be guaranteed at all costs. The switch must switch
the pump off before the pump's suction openings
can draw in air. See table for minimum water level.
