9 Decommissioning
9.1 General information on decommissioning
Information on decommissioning and course of action if there is a risk of
freezing

Drain the internal cooling water coil on the heating bath thermostat
and heating circulation thermostat (both directions suitable) using com-
pressed air or a watertight industrial vacuum cleaner.

If the device has a refrigerating machine, drain the cooling water circuit
on the refrigerating machine (both directions suitable) using compressed
air or a watertight industrial vacuum cleaner.

Drain the pump chamber on the circulation thermostat from the intake
side using compressed air or a watertight industrial vacuum cleaner.
NOTICE!
Risk of refrigerant escaping from refrigerant circuit
Device damage

Before decommissioning the device or if there is a risk of
freezing, drain the refrigerant circuit on the refrigerating
machine using compressed air or an industrial vacuum
cleaner (watertight). Blow compressed air through the cir-
cuit.
NOTICE!
Pump output decreases
Device damage

Before decommissioning the device or if there is a risk of
freezing, drain the pump completely from the intake side.
Blow compressed air through the circuit.
The following safety notices are relevant for devices containing natural
refrigerant:
WARNING!
Risk of refrigerant escaping from refrigerant circuit
Explosion, fire

Before decommissioning the device or if there is a risk of
freezing, drain the refrigerant circuit on the refrigerating
machine using compressed air or an industrial vacuum
cleaner (watertight). Blow compressed air through the cir-
cuit.
