place is not barricaded.
To prevent suffocation and poisoning caused by
venomous gases, make sure that enough oxygen exists
at the workplace.
If you have to work with welding tools or electric tools,
make sure that there is no explosion hazard.
Immediately after repair or maintenance work, all
safety and protection equipment must be reinstalled and
placed in function again.
The operator of the pump is responsible for third
parties within the work area.
Never put a hand or finger into suction inlet or dis-
charge of the pump while the impeller is rotating.
Persons are not permitted to stay in the pumping
medium during operation of the pump.
All other rules and regulations and local codes cover-
ing health and safety must be observed. In accordance

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 reliable by a 30 mA earth leakage circuit breaker.
H 800 series pumps are designed for pumping clear wa-
ter from tanks or cisterns.
HOMA deepwell submersible pumps are suitable for
pumping clear water with high pressure, even from close
boreholes, wells and pits. They are used for domestic
water supply, irrigation, garden watering from cisterns or
similiar, in fountain displays, watering place, heat pumps,
ground water drainage and so on. In combination with the
electronic control panel HPS 2 or with a pressure tank,
pressure switch and an electrical control panel the pumps
can operate automatically (see accessories).
Horizontal or vertical installation are possible, with vertical
installation also direct hanging of the pump up at the
discharge pipe.

5. Transport and Storage
Never use the cable or the discharge hose/pipe to lift,
lower, transport or attach the pump. Always use the han-
dle or a rope or a chain attached to the handle.
The pump may be transported and stored in vertical
or horizontal position. Make sure that it cannot roll or fall
over. For longer periods of storage, the pump should be
protected against moisture, frost or heat.
6. Electrical Connection
Before operation, an expert check must secure that
the required electrical protection measures exist. The
connection to ground, earthing, isolating transformer, fault
current breaker or fault voltags circuit must correspond to
the guidelines set forth by the responsible power plant.
The voltage required in the technical data sheet
must correspond to the existing line voltage.
Submersible pumps used outside of buildings must
have a cable with a minimum length of 10m.
