5.9.4 ADJUSTING APPLIANCE PARAMETERS
The appliance is delivered with pre-set parameters. Some param-
eters can be changed or adjusted if required. For further details,
please refer to section 7.
5.10 SETTING THE SYSTEM DESIGN PRESSURE
The design pressure should be a minimum of 0.5 BAR and a
maximum of 1.5 BAR.
The actual reading should ideally be 1 BAR plus the equivalent
height in metres (0.1 BAR = 1 metre) to the highest point in the
system above the base of the appliance (up to the maximum of 1.5
BAR total).
N.B. The safety valve is set to lift at 3 BAR/30 metres/45 psig.
To lower the system pressure to the required value, drain off some
water from the appliance drain valve until the required figure
registers on the pressure gauge (see fig. 1).
