Caution
3. General
Please take the necessary precautions when transporting the pump. Avoid intermediate stor-
age in a damp location or locations subject to significant temperature fluctuations. Our pumps
with built-in filter elements have been designed for pre-filtering and for the circulation of
swimming pool water. Most plastic components that come into contact with the pumping
medium are made of reinforced polypropylene (PP) and thus are highly resistant to corrosion
by pool water. The water temperature must not exceed 60°C. Non-compliance with our
installation and operating instructions will void any warranty.
Rotating parts
Risk of crushing or shearing from exposed rotating parts.
- Do not perform any work on the pump unless the power is shut down.
- Before starting work, make sure the pump cannot inadvertently be switched on again.
- Directly after finishing work, refit/reactivate all protective devices.
In the case of AK-type pumps the rotating pump shaft can trap hair, jewellery and items
of clothing.
When in the vicinity of a running AK-type pump:
- Wear close-fitting clothing.
- Wear a hairnet.
- Do not wear jewellery.
Electricity
When working on the electrical unit, there is an increased risk of electrocution due to the
damp surroundings.
Incorrectly installed protective conductors can also lead to electrocution e.g. as a result of
oxidation or cable breakage.
Make sure that the swimming pool and its surrounding protective zone are installed,
commissioned and operated in accordance with the relevant local regulations.
Before working on the electrical system, take the following precautions:
- Disconnect the system from the electrical power supply.
- Attach a warning sign: "Do not switch on! Work in progress on the system."
- Check for the absence of voltage.
Regularly check that the electrical system is in proper working order.
Hot surfaces
Risk of burns - the electric motor can reach temperatures of up to 70 °C.
- Do not touch the motor while it is running.
- Let the motor cool down before working on the pump.
