Operating Instructions
Temperature Control Unit 300L(D)/350L(D)
Connecting Lines
The connecting lines must consist only of pressure-resistant and tem-
perature-resistant hoses and screw fittings. The cross-section of the con-
necting lines may not be reduced (see maintenance section).
•
Outlet and inlet - use only pressure-resistant and temperature-
resistant hoses and screw fittings. The connecting lines must be
routed so that they are protected against unintentional contact.
Thermal expansion must be taken into account in pipe joints
•
Cooling water supply - when connecting to public water mains,
the applicable laws and safety regulations must be observed
(e.g., connection of the unit via circuit separator). The water
mains pressure must be within the range of 2-6 bar Use only
pressure-resistant and temperature-resistant hoses and screw fit-
tings
•
Cooling water outlet - must be free of back-flow and always
open. The hose must be fastened so that any escaping steam at
the start of the cooling procedure does not pose a hazard
•
Overflow - must always be open
CAUTION
If the cooler is leaky, thermal oil can enter the wastewater!
For reasons of safety, the cooling system must always be connected!
Electrical Connections
The temperature control unit may only be connected by a qualified elec-
trician.
•
Compare supply voltage and frequency with the information on
the rating plate of the temperature control unit
•
Verify the rating of the preliminary fuse according to the informa-
tion in the electrical diagram, and check that the power consump-
tion conforms to the value on the rating plate of the temperature
control unit
•
Observe the applicable local laws and safety regulations when
connecting to the mains
