6. Filling Requirements
6.1 Recommended bath liquids
+5°C to +80 ° C Distilled Water
Normal tap water leads to calcareous deposits necessitating frequent unit
decalcification.
Calcium tends to deposit itself on the heating element. The heating
capacity is reduced and service life shortened.
Water can be used up to 95°C, however above 80°C water vaporization
reaches a level which requires almost constant refilling.
NOTE: Add an appropriate amount of algicide to avoid any growth in the
water.
- 10°C to 80 ° C Water with Antifreeze
In applications below 5°C the distilled water has to be mixed with an anti -
freeze. The amount of antifreeze added should cover a temperature range
5°C lower (to a maximum -10°C) than the operating temperature of the
particular application. This will prevent the water from gelling (freezing) in
the area of the evaporating coil, whose surface area is much colder than the
working temperature. Too much antifreeze hampers temperature accuracy
due to its high viscosity.
We take no responsibility for damages caused by any unsuitable liquid.
6.2 Filling with heat transfer liquid
When working with water or water with antifreeze:
Fill the internal tank with approximately 3.6 liters of heat transfer fluid. Use
the filling port at the top left corner of the unit. Carefully adjust to the maxi

mum level, and check the level regularly. If level is below minimum, you'll
need to refill. Below the minimum level the cooling capacity is significantly
decreased .
External systems included within the circulating circuit have to be filled with
the same heat transfer liquid in order to avoid too much liquid being drawn
from the CC1080.
NOTE: Check the bath level when the preset temperature is reached.
If the closed external systems cannot be prefilled, the internal tank of the unit
has to be filled to the maximum level. After starting the unit, the pump will
feed the necessary liquid to the external system. If the demand is higher than
