5.2 Pump stop
The pump incorporates an electronic protective
function which will stop the pump in case of
• dry running,
• overtemperature,
• overloaded motor,
• seized-up motor/pump,
• frequent starts/stops (the "Alarm" indicator light
flashes) caused by
– leakage in suction pipe,
– dripping tap or
– running toilet.
The pump will restart automatically after 30 minutes
(for 24 hours) in case of any type of fault if the
Auto-reset function is activated (the green indicator
light on the control panel is on. See point 5 in the
table in section 5.1 Control panel).
6. Mounting and connection
6.1 Mounting the pump
The pump is resistant to sunlight and can be
installed both indoors and outdoors. When installed
outdoors, it is recommended to protect the pump by
means of a suitable cover.
Always mount the pump on the base plate with
horizontal suction port and vertical discharge port.
The pump must be mounted horizontally.
Maximum permissible inclination angle: ± 18 °.
See fig. 3.
Fig. 3
The pump must be secured to a solid foundation by
bolts through the holes in the base plate. See fig. 4.
Fig. 4
The pump discharge is flexible, ± 5 °, to facilitate the
connection. Never apply unnecessary force when
connecting the pipes.
The pump is supplied with G 1 (50 Hz) or 1" NPT
(60 Hz) screwed connections to be fitted in the
suction and discharge ports. See fig. 5.
Fig. 5
The pump incorporates a non-return valve which
prevents backflow during priming and operation.
Installations with long suction pipes: A non-return
valve is supplied with the pump. It is recommended
to fit this non-return valve in the pump suction port.
If the pump is installed in long pipes, the pipes must
be adequately supported on either side of the pump
in order not to strain the pump connections. If the
pump draws water from a well, it is recommended
also to fit a foot valve to the end of the suction pipe.
See fig. 6.
Fig. 6
If a hose is used for suction pipe, it must be of a
non-collapsible type.
As the pump is self-cooling, no space is required
around the pump and no ventilation is required.
6.2 Electrical connection
The electrical connections and additional protection
should be carried out by qualified persons in
accordance with local regulations.
The operating voltage and frequency are marked on
the nameplate. Make sure that the motor is suitable
for the power supply on which it will be used.
