8.4.1 Draining process
Pressurized cooling water connections
RISK OF INJURY

Wear your personnel protective equipment (e.g. safety goggles).

Carefully open the cooling water connection. Open slowly (1-2 signal edges) and drain the
cooling water slowly.
The building’s isolating valves are not closed
DAMAGE BY ROOM FLOODING

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 outlet< [14]
and/or >Cooling water drain< [15] (if any).
PROCEDURE
Temperature control units with >Cooling water drain< [15]

Close the isolating valves in the water supply on the temperature control unit (if present) and on
the building side.

Place a collecting container below the cooling water outlet [13], [14] and [15].

Open the >Cooling water drain< [15] and disconnect the >Cooling water outlet< [14] from the
water return. The cooling water will begin to drain out. Allow all the cooling water to drain out to
prevent the risk of freezing during transport and storage!

Disconnect the >Cooling water inlet< [13] from the water supply.

Close the >Cooling water drain< [15].
PROCEDURE
Temperature control units without >Cooling water drain< [15]

Close the isolating valves in the water supply on the temperature control unit (if present) and on
the building side.

Place a collecting container below the cooling water outlet [13] and [14].

Disconnect the >Cooling water outlet< [14] from the water return flow. The cooling water will
begin to drain out. Allow all the cooling water to drain out to prevent the risk of freezing during
transport and storage!

Disconnect the >Cooling water inlet< [13] from the water supply.
8.5 Deinstalling the collecting container
PROCEDURE

Remove the hose from the collecting container.
