Impacts, cutting, crushing

The main device must be disconnected from the mains or

the flow controller from the main device before any main-

tenance work is carried out.

Only skilled personnel are permitted to perform repairs.

CAUTION!

Contact with hot or cold device parts, accessories and heat

transfer liquid

Scalding, hot or cold burns

Allow device parts, accessories and heat transfer liquid to

reach room temperature before touching.

Protective equipment:

n

Safety glasses

n

Protective gloves

n

Protective work clothing

7.2  Maintenance intervals

Table 8

System component

Scope

Frequency

Hydraulic circuit

Visual inspection for damage

At every start-up, then daily.

Hoses

Visual inspection for leaks and material

fatigue

At every start-up, then daily.

n

Comply with these maintenance intervals without fail. Failure to do so

endangers the safe operation of the constant temperature equipment

and Durchflussregler.

n

Remedy any defects found immediately, at the latest before the next

operation.

n

In the case of major damage, contact the manufacturer immediately
