5.11 REGULATING THE HOT WATER
The appliance is fitted with a flow rate restrictor that limits the
maximum flow rate that can be drawn through the appliance.
The restrictor eliminates the need to manually adjust the DHW flow
rate. However if it is felt necessary to further increase or decrease
the available flow rate, spare restrictors are included in the acces-
sory pack.
The spare flow rate restrictors can be fitted to either increase or
decrease the maximum flow rate. The tables overleaf denote the size
of restrictor fitted and the spare restrictors supplied in the accessory
pack. Each restrictor is colour-coded to enable identification.
