Flow Requirements
Your heater is factory set to accept input water ow entering on the left
and exiting on the right, this can be reversed by rotating the ow switch
180 degrees (ie:½ turn, see g 6)
WARNING! The ow switch paddle can be damaged when reversing the ow
direction if it is lifted by more than 5mm from its housing and turned with
force. If the ow switch has been rotated it is important to ensure that it is
nally locked in the correct orientation perpendicular (at right angles) to the
ow of water.
The ow rate of water into the heater must not exceed 17,000 litres per
hour (3,740 UK gallons/hour) A higher ow rate will require the installation
of a bypass to prevent damage to the heater elements. The heater will not
operate unless the following minimum ow rates are achieved ie:
1,000 litres / hour (220 UK gallons/hour) for 2 ~ 6-kW heaters and
4,000 litres / hour (880 UK gallons/hour) for 9 ~ 24-kW heaters.
