9.4 Air purging
When commissioning and installing the unit, it is very important to remove all air in the water circuit.
Automatic air purging is possible via manually starting the primary pump of the ClimateHub via the self test mode (water
pump On/Off) in the service menu (password 0202) of the wired remote controller.
Before commissioning the unit, make sure to check the following points:
1 The maximum water pressure of the unit is 2.9 bar static pressure.
2
3 The minimum required water flow for operation is 16 liters/min (this is not the same as the standard or nominal flow, for
details see section 6.1 Flow Rate).
At all times the required water flow rates should remain.
A flow error can stop the compressor.
• Water quality must be according to EN directive 98/83 EC.
• If the unit and the pipes are exposed to freezing temperature, it can cause damage to the hydraulic system. Special
care must be taken to prevent freezing of the total water system.
• The unit is designed to be used in a closed-loop system. Do not use any other components which are designed only for
an open-loop system.
• Never use Zn-coated parts in the water circuit.
• All hydraulic parts including field piping must be insulated to reduce heat loss and condensation.
