 Remove and clean the metal strainer located below.
 Clean the metal strainer under running water.
 Re-insert the metal strainer after cleaning work.
 Carefully fasten the cover (hexagonal).
 Re-mount the panel around the >Cooling water inlet< [13] and >Cooling water outlet< [14].
 Open the customer’s shut-off valves in the cooling water supply and return lines.
 Connect the temperature control unit to the power supply.
 Switch the temperature control unit on.
We also provide service training. Please contact the Customer Support. The telephone number can
be found on page 95, section »Phone number and company address«.
7.3.5 Empty the drip tray
Non-compliance with the safety data sheet for the thermofluid to be used
INJURIES
 Risk of injury to the eyes, skin, respiratory tract.
 The safety data sheet for the thermofluid to be used must be read prior to use and its contents
respected.
 Observe the local regulations/work instructions.
 Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety
goggles, safety footwear).
 Danger of slipping because floor and work area are contaminated. Clean the work station and
follow the instructions for the disposal of thermofluid and material on page 16 in section
»Proper disposal of resources and consumables«.
This is not an actual leak but residues that are necessary for the lubrication of the mechanical seal.
The exiting quantity of thermal fluid is dependent on the thermal fluid itself and the working tem-
perature of the temperature control unit. The drops in the drip tray usually evaporate in case of
thermal fluids with a high vapor pressure. The drops usually do not evaporate in case of thermal
fluids with a low vapor pressure (e.g. silicone oils). Therefore, these residues must be drained from
time to time.
PROCEDURE
 Hold a suitable container, e.g. beaker, below the >Drain drip tray< [7]. The drips can be cleanly
collected in the beaker and properly discarded. When cleaning filling accessories, observe page
16 section »Proper disposal of resources and consumables«.
 Open the >Drain drip tray< [7].
 Collect the drips.
 Close the >Drain drip tray< [7].
7.4 Thermal fluid inspection, replacement and circuit cleaning
The illustration “connection diagram” can be found on page 96 in section »Annex«.
Extremely hot / cold surfaces, connections and thermal fluids
BURNS/FREEZING OF LIMBS
 Surfaces, connections and tempered thermal fluids can be extremely hot or cold depending on
the operating mode.
 Avoid direct contact with surfaces, connections and thermal fluids!
 Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety
goggles).
7.4.1 Thermal fluid inspection
Thermal fluid is not inspected on a regular basis
BURNS DUE TO REDUCED BOILING POINT
 Regularly check your thermal fluid whether it meets the specifications in the safety data sheet.
