4.2 Pump stop
The pump incorporates an electronic protective func-
tion which will stop the pump in case of
• dry running,
• overtemperature,
• overloaded motor or
• seized-up motor/pump.
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 4.1 Control panel).
5. Mounting and connection
5.1 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 hori-
zontal 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 con-
necting the pipes.
The pump is supplied with 1" NPT screwed connec-
tions to be fitted in the suction and discharge ports,
see fig. 5.
Fig. 5
The pump incorporates a check valve which prevents
backflow during priming and operation.
Installations with long suction pipes: A check valve is
supplied with the pump. It is recommended to fit this
check 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.
