8. Using the system for its
intended purpose
This system is used for pumping a cleaning
liquid at high-pressure, for the purpose of:
„ with the handgun attached – cleaning
containers, boxes, cases and equipment
parts, etc.
„ with the interior cleaner attached –
cleaning enclosed containers, drums,
barrels, etc.
Cleaning the following is considered to be
contrary to the intended purpose, and is
strictly forbidden:
„ Persons and animals
The high-pressure jet represents a serious
injury hazard.
„
Loose objects
Such items could be catapulted away by
the high-pressure jet, causing damage to
property or injury to persons.
If water is used as the cleaning liquid, the
system must be protected against freezing
temperatures. Damage could be caused if
water freezes inside the system.
9. Special Conditions in a
hazardous area
1. The pump may only be used in zones
which correspond to the type of explosion
protection given on the rating plate.
2. The cleaning liquid must not contain more
than 1% by weight of undissolved solids.
3. The interior cleaner must be
electrostatically grounded.
4. The cleaning liquid pump may only be run
if it is filled with liquid.
5. The nominal pressure of the pump must
not exceed 50 bar when used with solvents.
A. For your safety
6. The pump's flow rate must not exceed
50 l/min when used with solvents.
7. The operating temperature of the cleaning
liquid, made up of water with cleaning agent,
must not exceed 60 °C.
8. The operating temperature of the cleaning
liquids must not exceed 20 °C where
solvents, lyes (alkali solutions) and acids
are used.
9. The pump must be inspected after a
reasonable operating time to ensure it has a
faultless condition and function (among
other things, bearings for wear, pump for
leaks, tension in the V-belt). Repair if
necessary.
10. The pump may only be operated with
cleaning liquids against which the materials
from which the pump is made have
adequate resistance.
11. Cleaning liquids, which contain
combustible solvent fractions, must
correspond to the temperature classes IIA
and IIB. Solvents in the temperature class
IIC must not be sprayed.
12. The pump may only be operated in Zone
1 during cleaning. Ensure compliance with
the conditions applicable within the scope of
the BetrSichV (industrial safety regulations)
and other national conditions.
13. Hoses must be electrostatically
conductive (resistance R < 1 M
Ω
).
14. Only use cleaning liquids with a
conductivity G > 1000 pS/m.
15. All parts in contact with the media are to
be connected to the earth connection
system.
16. The electric motor used must have a
prescribed type testing certificate to
94/9/EC.
