5. Electrical connection
!
All electrical connections should be performed by a
qualified 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
protected with a I
ΔN
≤ 30 mA differential switch.
Please make sure that the electrical installation has a
disconnecting device, which allows disconnection 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 the power of the motor and the length
of the cable. Single-phase motors are equipped with a built-in
overload switch.
6. Initial start-up
Caution
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 the transparent lid on 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.
Before initial start-up and after extended periods of downtime
make sure the pump shaft turns freely.
7. Maintenance
Caution
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 pressure lines.
The strainer basket must be emptied periodically. A clogged
strainer basket will reduce the flow rate of the pump and lead to
insufficient filtration. The pump is to be thoroughly drained and
cleaned after extended periods of storage or downtime.
Do not add water treatment agents, particularly agents in
tablet form, to the strainer basket!
Caution
If there is danger of freezing during prolonged periods, the
pump must be drained ahead of time. To do this open the
drain plug in order to drain off all liquid. Drain all pipes at risk
of freezing.
Before doing any maintenance work, switch
off the pump and disconnect it from the power supply.
