10.0 MAINTENANCE -

EXPANSION VESSEL PRECHARGE PRESSURE

The Expansion Vessel should have a precharge pressure of 3.5 bar (51
p.s.i.). This can reduce over time and eventually require re-charging. To
do this:
10.1 Turn off water supply to the unit; open a hot tap to relieve system
pressure.
10.2 Remove dust cap from top of Expansion Vessel
10.3 Check pre-charge pressure using a tyre pressure gauge. If the
pressure is lower than 3.5 bar (51 p.s.i.) it should be recharged
using a tyre pump (Schraeder Valve type). DO NOT OVER
CHARGE.
10.4 Re-check pressure and when correct replace dust cap.
10.5 Turn on mains water supply and close hot tap.
