3.3 The cold water supply may be taken from the cold water mains or from a cold
water feed cistern complying with Water Byelaw 30 with a minimum recom-
mended pressure of 0.4 bar (4 metres).
3.4 The inlet and outlet connections of the heater must be connected to the Open
Outlet tapset in accordance with the Fitting Instructions supplied with the tapset.
The inlet must not be connected directly to the cold water mains supply.
3.5 In an Open Outlet installation it is normal for the tap to drip during heating. This
is due to expansion of water as it is heated within the unit, it does not indicate a
fault. DO NOT attempt to stop this dripping by over-tightening the tap as
damage to the sealing washers or internal operating mechanism will occur.
