7.3.2 Replacing coolant hoses
Replace defective coolant hoses before turning on the temperature control unit.
PROCEDURE

Drain the cooling water. → Page 43, section
»Draining the cooling water«
.

Replace the defective coolant hoses. Follow the instructions for the proper disposal. → Page 15,
section
»Proper disposal of resources and consumables«
.

Reconnect the temperature control unit to the building’s cooling water supply. → Page 25, sec-
tion
»Temperature control units with water cooling«
.

Restart the temperature control unit in normal mode.
7.3.3 Clean liquefier fins (air-cooled temperature control unit)
Manual cleaning
RISK OF BEING CUT ON THE LIQUEFIER FINS

Wear suitable cut-resistant gloves for cleaning work.

Depending on the ambient conditions, use cleaning equipment such as vacuum cleaners and/or
a hand brush/brush. Follow the local regulations when cleaning. Do not clean the liquefier fins
in a clean room with items like a brush and do not use a vacuum cleaner without an extra-fine
particle filter.
Cleaning using pointed or sharp-edged tools
DAMAGE TO THE LIQUEFIER FINS

Clean the liquefier fins using suitable cleaning appliances.
Make sure there is adequate ventilation (removal of waste heat, fresh air supply) for the tempera-
ture control unit, in case of air cooling, maintain wall clearance . → Page 18, section »Exemplary
illustrations of the cooling variants« and → Page 22, section »Ambient conditions« .
The liquefier fins must be cleaned (dust) from time to time as only then will the temperature con-
trol unit perform at its maximum cooling capacity.
PROCEDURE
Liquefier fins on lower surface

Switch off the temperature control unit.

Disconnect the temperature control unit from the power supply.

Tilt the temperature control unit to its side. Make sure the cooling coil is not bent.

Clean the liquefier fins using suitable cleaning appliances. Observe the local regulations and
ambient conditions when selecting cleaning appliances.

Make sure the liquefier fins are not damaged or deformed as this will impair the air flow.

Put the temperature control unit upright immediately after cleaning the liquefier fins and wait
for
60 minutes
to allow the compressor oil to flow back.

Connect the temperature control unit to the power supply.

Switch on the temperature control unit.
7.3.4 Clean hat-type strainer (dirt trap) (water-cooled temperature control unit)
Building’s isolating valves are not closed
PROPERTY DAMAGE CAUSED BY FLOODING OF ROOMS

Close the building’s isolating valves in the cooling water supply and return lines.

For table-top models, place a collection container below the >Cooling water drain< [15]. Ob-
serve the wiring diagram: → From page 46, section »Annex« .
The strainer at the cooling water inlet must be inspected and cleaned on a regular basis, depend-
ing on water quality.
