Insulate
Only utilise thermal insulation shell in heating applica-
tions with fluid temperature > 20 °C.
During cold and air-conditioning applications use
standard, diffusion-proof insulation materials. Empty

Observe voltage rating on the rating plate.
Maximum back-up fuse: 10 A, inactive or circuit breaker
with C characteristic
Never connect to an uninterruptible power supply or
IT-networks.
During external connection of the pump deactivate a
pulse of the voltage (for example phase angle control).
Switching the pump via triacs/solid-state relays must be
examined on a case-by-case basis.
During deactivation with on-site power relay:
Rated current ≥ 10 A, rated voltage 250 V AC
Note switching frequency:
– Switching on/off mains voltage ≤ 100/24 h
– ≤ 20/h at a switching frequency of 1 min between
switching on/off via mains voltage
Secure pump with a residual-current device (type A or B).
Leakage current I
≤ 3.5 mA

The electrical connection must be made via a fixed
connecting cable equipped with a connector device or an
all-pole switch with a contact opening width of at least
3 mm (VDE 0700/Part 1).
To protect against leakage and for strain relief to the
threaded cable connection use a connection pipe with
sufficient outer diameter
Use a heat-resistant connecting cable where fluid tem-
peratures exceed 90 °C.
Lay the connection pipe in such a way that it touches
neither the pipes nor the pump.
