CAUTION
Refrigerant can be very cold
Risk of severe frostbite.
Avoid any contact with the refrigerant.
For this, observe the following information:
Monitor the boiling temperature of the refrigerant. With
water as a coolant, for example, it may not fall below
4°C.
If the refrigerant is extracted as a gas, the coolant cir-
cuit must also be in operation. The temperature of the
coolant must be monitored where the refrigerant is
sucked off and increased if necessary.
Dispose of the refrigerant properly.
7.3 Draining the oil
Before decommissioning the pressure equipment or
performing repair work, shut off the refrigerant pipes
and oil pipes before and behind the oil cooler. Keep a
pan ready. Drain oil, collect oil and dispose of it prop-
erly.
WARNING
The pressure equipment is under pressure!
Serious injuries are possible!
Depressurise the pressure equipment!
Wear safety goggles!
8 Decommissioning
In case of damage, the pressure vessel must be separ-
ated from the refrigerator system and replaced. For
this, extract the refrigerant and remove the oil.
Dispose of contaminated substances properly! Chlor-
ine-containing oil is hazardous waste.
