5. Electrical Connection
All electrical connections should be performed by a quali
-
fied expert only!
Make sure all parts are free of tension before doing any
maintenance work or electrical work.
The
use of pumps for swimming pools and the restricted area
around them is only permitted if pumps are installed in accordance
with DIN/VDE 0100 part 702. The supply circuit has to be protec-
ted with a fault current contactor with a nominal fault current of
I
ΔN
≤ 30
mA.
Please make sure that the electrical installation has a disconnec-
ting device, which allows disconnecting from the power supply
with a minimum of 3 mm contact gap at each pole.
In
accordance with norm requirements an electrical cable type
H05RN-F or H07RN-F must be used.
Please ensure that the diameter of the electrical cable used
adequately accommodates for the power of the motor and the
length of the cable. Pumps with single-phase motor are equipped
with a built-in overload switch.
6. Initial start-up
Unscrew the ring nut and lift off the transparent lid. Slowly fill
the pump with clean water until the water level reaches the inlet
connection. Put on the transparent lid and tighten the ring nut
by hand.
Never operate the pump without water even when
checking the rotation direction of the motor!
Ensure that all
valves in the suction and pressure lines are completely open. Be-
fore initial start-up and after extended periods of downtime make
sure the pump shaft turns freely.
7. Maintenance
Before carrying out any maintenance work, the electricity supply
to the pump must be switched off. Close the shut-off valves on the
suction and on the pressure line.
The strainer basket must be periodically emptied. A clogged strai-
ner basket will reduce the flow rate of the pump and lead to insuf-
ficient filtration. The pump is to be thoroughly drained and clea-
ned after extended periods of storage or down-time.
Do not add water treatment agents, particularly agents in
tablet form, into the strainer basket!
If there is danger of freezing during prolonged periods, the pump
must be drained ahead of time. For this purpose open the drain
plug in order to drain off all liquid. Drain all pipes subject to
freezing.
Before doing any maintenance work, switch off the
pump and disconnect it from the power supply.
