Electrical Connection; Initial Start-Up - aqua technix AQUA Plus Timer OKU Instructions De Montage Et D'utilisation

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 fault
current contactor with a nominal fault current of I
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. Pumps with 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 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. 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 on the pressure lines.
The strainer basket must be periodically emptied. 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 down-time.
Do not add water treatment agents, particularly agents in tablet
form, into the strainer basket!
Caution
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 which could be subject to freezing.
Before doing any maintenance work, switch off the pump and
disconnect it from the power supply.
