CHECKING THE OPERATION OF SAFETY VALVES

Manually operate the valve lever on the Pressure Relief Valve for a few seconds. Check that water is discharged and that it
flows freely through the tundish and discharge pipework. Check that the valve reseats correctly when released.
Repeat the procedure for the Temperature & Relief Valve, if installed. Note: The water discharged may be very hot.

FILLING THE AUDAX AND CENTRAL HEATING SYSTEM

Follow the Immergas Audax Instructions, "Installation of the Unit" section. Ensure that water quality guidelines are fol-
lowed.
7.5

ANNUAL MAINTENANCE

The Inoxstor should be inspected and serviced annually. As a minimum, check operation of both pressure relief valve and
T&P valve (if installed), check system for leaks, check expansion vessel and check operation of immersion thermostat.
Important: After servicing, preliminary electrical system checks must be carried out to ensure electrical safety (i.e. polarity,
earth continuity, resistance to earth and short circuit).
Annual maintenance of the Immergas Audax Heat Pump should be carried out as specified in the Immergas Audax Heat
Pump instructions.
