2.2. General Safety Precautions

General regulations and guidelines not mentioned in the
safety warnings retain their validity.
These operating instructions contain basic instruc-
tions, which have to be adhered to during installation, op-
eration and maintenance. These operating instructions
must be read from mechanic and the operator before in-
stallation and operation of the pump and have to be kept
available at the operating place of the machine/unit at all
times. Persons who are not familiar with the operating in-
structions shall not use this product.
Children and adolescents under age 16 shall not use
the pump and must keep away from the machine/unit
while it is operational.
The working area has to be closed off expediently
and must adhere to local workplace regulations.
Always use personal safety equipment such as safety
boots, rubber gloves, safety glasses and helmet.
Make sure that the emergency exit from the workplace
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 par-
ties 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 me-
dium during operation of the pump.
All other rules and regulations and local codes cover-
ing health and safety must be observed. In accordance
with product liability law, we point out that we shall not be
liable for damages caused by the pump due to non-

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.H 501 up to H 508 pumps are designed for drain-
age of dirty water, pumping clear water, or leakage water
with abrasive solids. The pumps are used to pump surface
water from building sites, wells, subways or tunnels, for
lowering ground water, for irrigation, application on board
ships etc.
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.

15 starts per hour. Our standard warranty and mainte-
nance regulations refer to intermittent operation. For re-
duced warranty periods and service intervals due
to continuous operating conditions please contact our ser-
vice department.
3.4. Explosive Environments
For operation of the pumps in explosive environments
see models with explosion-proof motors (Ex model) from
the HOMA range.
For each individual installation the explosion classifi-
cation (Ex-class) of the pump must be approved by the
local authorities.

4. Warranty

Our warranty only covers pumps which are installed and
operated in accordance with these installation and opera-
tion instructions and accepted codes of good practice and
