8. DECOMMISSIONING/SHUTDOWN
Follow the safety notes in chapter 1!
• Disconnect the cooling unit from the power supply
• Completely drain the water circuit, including pipework, evaporator, pump(s),
water filter and tank(s)
(See RI flow diagram in technical section)
In the case of transport after operation with water, we recommend rinsing the cooling unit
with a water-glycol mixture of 60% : 40% after draining!
Tasks to be carried out:
1. De-energise the cooling block and disconnect the power supply
2. Disconnect the device from the application on the water side (this results in venting of the
cooling block)
3. Completely drain the water circuit; in the case of height differences in the inlet line to the
evaporator, the water must be pushed out with compressed air
4. Completely drain the tank via the drain cock, then clean and rinse
5. Completely drain the pump(s) via the purging hole (ensure that pump(s) are vented)
6. Check, if required remove remaining water
7. Close device connections
8. Protect the cooling block against dust
9. Package for transportation, if required
10. Water containing additives must be disposed of in consultation with the responsible authorities
at regional level
