Frost protection measures
The chiller is exposed to a frost hazard by two different situations. Both an ambient
temperature < 0°C and a flow temperature < 8°C entail the risk of freezing of system parts of the
cold water circuit.
Installation at ambient temperature < 0°C with antifreeze
The machine is protected against freezing by an antifreeze. Always comply with the requirements
with regard to the operating liquid and mix ratio. This also applies to the version with water-cooled
condenser (
Chapter 3.3 Version with water-cooled condenser
).
Flow temperature < 8°C
The machine must be protected against freezing by an antifreeze in accordance with the
specifications. Please note that the evaporation temperature is always significantly lower than the
cold water flow temperature. A risk of freezing can exist even in a supposed safe temperature range.
Comply with the requirements with regard to the operating liquid and mix ratio.
6.2.15.
Flushing the cold water circuit
Dirt in external pipes and components can damage the chiller. Before the chiller is connected
hydraulically with the cold water circuit, the cold water circuit must be flushed several times. If there
are dirt traps in the cold water circuit they must be cleaned after flushing the pipes.
6.2.16.
Filling
If the hydraulic installation of the whole system has been completed, the unit can be filled. Open
all the stopcocks in the cold water circuit.
WARNING! Use approved liquids only, see Chapter 2.15! In case of a frost
risk, note and follow Chapter 6.2.14. !
All the operating liquids must be mixed before they are added to the chiller!
Procedure for chillers with integrated tank:
The chiller can be filled via the tank without pressure.
Procedure for chillers without integrated tank:
The standard machine without integrated tank does not have a filling connection. To fill the system
you must provide a filling connection in the process circuit. If an external tank is installed in the
process circuit, fill your system directly in this tank.
