4.4.4 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.
4.4.5 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.
4.4.6 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.
