Fault Finding And Servicing - Potterton Gold Installation And Servicing Instructions

OPERATIONAL FAULTS
Operational faults and their possible causes are
detailed in the Fault Finding section of this book. It
is recommended that faults should be checked by
a competent installer.
The air volume within the expansion vessel will
periodically require recharging to ensure expanded
water is accommodated within the unit. A discharge
of water INTERMITTENTLY from the expansion
valve will indicate the air volume has reduced to
a point where it can no longer accommodate the
expansion.
