No need to adjust initial pressure of
expansion tank
Things need to do :
Must reduce initial pressure. Calculate it based
on the section “initial pressure of expansion
tank”. Check water capacity is lower than
allowed maximal water capacity (using the
figures below).

Things need to do :
Must increase initial pressure.
Calculate it based on the section “initial
pressure of expansion tank”.
Check
water capacity is lower than allowed
maximal water capacity (using the
figures below).
The expansion tank is too small to install. (It
needs proper expansion tank or use safety
valve with high activated pressure that is
supplied from local place)
