Risk of material damage when installing cooling registers!
The following must be taken into account when installing cooling registers:
– Close all hydraulic stop valves.
– Isolate all connections and ensure that the unit is leak-free with regard to water.
– Since the diameter of the cooling pipes is small, water may remain in the register after emptying. For safety reasons,
compressed air should be blown through the system to remove the remaining water.

connections must be carried out by a person who has proper professional training and experience in the relevant acci-
dent prevention regulations, as well as other generally recognised safety and occupational health codes, with authori-
sation to perform work on the unit.
Risk of injury due to electric shock, hot surfaces (AIR1 unit fan) and potentially hot surface of optional auxiliary
heater .
– Ensure that the multi-leaf dampers are installed for frost protection.
– The air ducts behind the cooling register must be insulated.
– The flow and return pipes must be insulated.
If the water temperature falls below 0 °C, the freezing temperature of the water can be reduced by adding ethylene
glycol. The mixing ratio of ethylene glycol is shown in the illustration below (Fig. 6).
