Examples of such safety measures:
Pumps running in parallel on a separately protected power circuit,
moisture sensors for switching o ff the pumps, and similar safety ar-
rangements.
Be sure to consult a professional plumber if you have any doubt.
The maximum pumping rate is possible only with the largest possible
line diameter; if smaller hoses or pipes are connected, the pumping
rate will be reduced. If the universal hose connection (Fig. 1/Item 4)
is used, it should be shortened (as shown in Fig. 4) to the connection
actually used in order not to reduce the pumping rate unnecessarily.
Flexible hoses must be fastened to the universal hose connection
with a hose clip (not included in the scope of supply).
When installing, never hang the equipment by the discharge line or
by the power cable. The equipment must be hung up with the provi-
ded carry handle or it must rest on the bottom of the shaft. To ensure
that the equipment works properly, the bottom of the shaft always
must be free of sludge and other accumulations of dirt. If the water
level is too low, the sludge in the shaft can quickly dry out and hinder
the equipment from starting. It is necessary therefore to check the
equipment regularly (carry out trial start-ups).
The pump shaft should be large enough.
5.2 Mains connection
Danger!
The equipment you have purchased comes with an earthing-pin plug.
The equipment is designed for connection to a socket outlet with
earthing contact for 230 V ~ 50 Hz. Make sure that the socket-outlet
is su ffi ciently fused (at least 6 A) and in good working order. Insert
the power plug in the socket-outlet and the equipment is ready for
operation.
