3
Close all water taps after all air is purged.
4
Check for water leaks.
5
Manually operate the field-installed pressure relief valve to ensure a free
water flow through the discharge pipe.
8.6.7 To insulate the water piping
The piping in the complete water circuit MUST be insulated to prevent
condensation during cooling operation and reduction of the heating and cooling
capacity.
If the temperature is higher than 30°C and the humidity is higher than RH 80%, the
thickness of the insulation materials should be at least 20 mm to prevent
condensation on the surface of the insulation.
