Instruction Manual, Gunclean Toftejorg TZ-75 Portable
Standard machines and machines delivered with ATEX certification
in accordance with Directive 94/9/EC
IM-TE91A251-EN3
Installation and Normal Operation
(continued)
Normal Operation
Cargo and Cleaning Media
: Use only media compatible with stainless steel, polymer and carbon.
Normal detergent, moderate solutions of acis and alkalics will be acceptable. Agressive chemicals,
excessive concentrations of chemicals at elevated temperatures, as well as certain dissolvents and
hypochlorids should be avoided. If you are in doubt, contact the local Alfa Laval Tank Equipment
distributor.
After Use Cleaning
: After use flush the machine with fresh water. Cleaning solutions should never be
allowed to dry or set-up in the system due to possible "salting out" or "scaling" of the cleaning
ingredient. If cleaning media contains volatile chloride solvents, it is recommended not to flush with
water after use, in case this can create hydrochloric acid.
Pressure:
Avoid Hydraulic shocks. Put on pressure gradually. Do not exceed 12 bar inlet pressure.
Recommended inlet pressure appears from Technical Data (page 8-9). High pressure in combination
with high flow rate will increase consumption of wear parts.
ATEX
Warning:
If stream cleaning is done through the machine, the steam pressure must not cause
the machine to rotate.
ATEX
Warning:
If the machine is drained using compressed air, then the compressed air pressure
must not cause the machine to rotate.
Temperature
: In accordance with the ATEX specifications regarding special conditions for safe use,
see page 15.
ATEX
Warning:
Tanks with capacities greater than 100 m
3
that could contain a flammable atmosphere
should not be steam cleaned, as steam issuing from a nozzle could contain charged
droplets.
Tanks smaller than this may be steam cleaned providing that: the steam nozzles and
other metal parts of the system are reliably earthed and grounded to the tank
structure.
ATEX
Warning:
In potentially explosive atmospheres, the temperature must not exceed the maximum
surface temperature according to the temperature class for the combustible gas or
liquid.
