3. Applications and Technical Description

3.1. Applications

If the pump is used for cleaning or maintenance of

swimming pools, make sure that no persons stay in the
swimming pool during operation of the pump and that the
pump is self-assured by a 30 mA earth leakage circuit
breaker.

CR 252 pumps are designed for pumping dirty water like
rain water or ground water with solid sizes (for spherical
clearance see 3.2).
The pumps are used for pumping water from basements,
cellars or surface water from sumps.
The pumps must not be used for pumping of liquids con-
taining great quantities of abrasive solids, like sand or
stones. Before the pumping of chemically aggressive liq-
uids, the resistance of the pump materials must be
checked.
The pumps may be used for both temporary or permanent
installation. The installation can be free-standing on a
base-stand system (available as accessory).
