3. Applications and Technical Description
3.1. Applications
If the pump 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 30 mA earth leakage circuit
breaker.
Series CH pumps are designed for the pumping
drainage water containing chemical polutes. If in accor-
dance with local laws and regulations, the pump types CH
446 may be used for the pumping of raw sewage.
The pumps must not be used for the pumping of liquids
containing great quantities of abrasive solids, like sand or
stones. Before the pumping of chemically aggressive
liquids, 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
basestand or by means of an auto-coupling guide rail
system (available as accessory).
The pumps may be used for both temporary or permanent
installation. The installation can be free-standing on a
basestand (CH 446 with ring base stand, available as
acesory) or by means of an auto-coupling guide rail sys-
tem (available as accessory).
