14. Cooling

The refrigerated bath is used mainly for lowering the ambient or tap water
temperatures in the circulators, or for cooling a heated application down to a
lower temperature very quickly.

The working temperature range is shown in the technical specifications.

Switch the refrigerated bath off using the cooling switch

NOTE:

Switching the cooling compressor on for quick cooling down purpos-

es (even at working temperatures of 80°C) is permissible.
