1. Flush the tank with fresh mains water then fill, vent and pressurise domestic water circuit
as previously described.
IMPORTANT: Always fill and pressurise the secondary (domestic) tank first,
filling and pressurising the primary (heating) tank may result in crushing
damage to the domestic tank.
2. Fill the primary circuit taking care not to exceed 2 Bar.
3. Purge the air from the primary tank.
4. Switch on and operate.
IMPORTANT NOTE:
ACV recommends the use of a corrosion inhibitor in the primary (heating) system.
The warranty will be invalidated if upon inspection it is found that a tank has failed
due to corrosion caused by the lack of an inhibitor.
