2.2. General Safety Precautions
General regulations and guidelines not mentoined 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 work-
place is not barricaded.
To prevent suffocation and poisoning caused by ven-
omous 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 sa-
fety 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-
observance of the instructions and guidelines set forth in
the operating instructions. The same product liability are
valid for accessories.
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.
TP 28 and TP 30 pumps are designed for
pumping waste
water, or groundwater, containing sludge or soft solids.
The pumps are used for installations in public and private
sector, trade and industry.
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 che-
cked.
The pumps may be used for both temporary or permanent
installation. The installation can be free-standing on a ba-
se-stand or by means of an auto-coupling guide rail
system (available as accessory).

3.3. Operating Conditions
Maximum liquid temperature: 35°C, short term up to
60°C.
Density of pumped liquid: max. 1100 kg/m
3
Ph-value of pumped liquid: 5 up to 11.
Level of pumped liquid: The lowest level must always
be above the top of the pump housing (volute).
Operation: The motors are designed for continuous op-
eration (S1) with fully submerged motor, maximum 15
starts per hour. Our standard warranty and maintenance
regulations refer to intermittent operation. For reduced
warranty periods and service intervals due to continuous
operating conditions please contact our service
department.
3.4. Explosive Environments
For operation of the pumps in explosive environments
only models with explosion-proof motors (Ex model) must
be used.
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
being used for the applications mentioned in these in-
structions.
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.
