1.3 Security advice
For the installation and operation of the cooling machine, the following
regulations and safety notes 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.
The electrotechnical connections of the cooling machine 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.
Before attempting to carry out any work on the process cooler,
always disconnect the unit from the power supply.
.
National standards applicable in the country where the unit is
installed must be complied with.
The safety equipment is not to be suspended.
Alterations of operation parameters of the cooling device are to be
carried out by authorised and introduced persons only.
The enclosed refrigeration cycle contains refrigerant and oil, which
must be disposed professionally (environmental care).
Cooling water additives have a caustic effect on the human skin
and eyes. When handling cooling water additives, wear eye-
protective glasses and safety gloves. Observe instructions on
product packing.
The operative range of the cooling machine has to perform
according to the determined technical data. (see chapter Technical
Data).
Watch out for any incompatibilities of materials in the entire water
circuit.
1.4 Purpose
Cooling machines are designed and constructed to keep the
temperature of a consumer medium constant within the determined
operation range by means of a cooling process (water at determined
quality or water with additives).
Operation has to be exclusively within the calculated load and operating
range.
