7.6.5 To fill the water circuit
To fill the water circuit, use a field supply filling kit. Make sure you comply with the
applicable legislation.
INFORMATION
Make sure both air purge valves (one on the magnetic filter and one on the backup
heater) are open.
7.6.6 To fill the domestic hot water tank
1 Open every hot water tap in turn to purge air from the system pipe work.
2 Open the cold water supply valve.
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.
7.6.7 To insulate the water piping
The piping in the complete water circuit MUST be insulated to prevent
condensation during defrost operation and reduction of the heating 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.
