1.3 Safety Notices
For the installation, operation and maintenance of the process cooler, the following regulations
and safety notices have to be observed:
Any work on the process cooler may only be performed by qualified personnel.
All relevant accident prevention regulations have to be observed.
Do not allow anybody to stand or pass underneath the forks when lifting and setting
down the process cooler; stay clear of the danger area.
The process cooler must be properly secured in order to prevent it from tipping over.
The safety devices must not be deactivated.
The electrotechnical connections of the process cooler must be performed according
to and conforming with all relevant VDE, EN and IEC standards. Beyond that, the
technical connection requirements of the local electrical utility company have to be
observed.
Do not attempt to perform any work unless the main power supply to the process
cooler has been disconnected.
Specific regional or national provisions applicable in the country where the unit will
be installed must be adhered to.
The closed refrigeration circuit contains refrigerants and refrigeration oil. These must
be properly disposed of when performing service work or placing the unit out of
service (environment).
The cooling water additives have a caustic effect on skin and eyes. When working
with cooling water additives, eye protection devices and gloves must be worn. Follow
the directions on the product’s label.
Anyone working on the refrigeration circuit must be protected by personal protective
equipment.
The process cooler is to be used exclusively for the cooling of water in accordance
with predefined specifications.
Watch out for any incompatibilities of materials in the entire water circuit.
The water must be free of all substances that could result in mineral deposits and
corrosion!
The water used in the cooling circuit must comply, at a minimum, with the values specified by
the Ordinance on Drinking Water. In the case of de-ionised water, additional constructional
features are necessary.
Based on the drinking water ordinance the following limit values are recommended:
- Electric conductivity: < 2500 µS at 20 °C
-Hydrogen concentration: 7 ... 9 (pH-value) at 20 °C
-Chloride: < 250 mg/l
-Total hardness: < 30 °dH
-Colony count: < 100 ml at 22 °C
