Stainless Lite direct is an electrically heated,
unvented hot water storage cylinder designed
primarily for use with off peak electrical
supplies.
It is supplied fitted with two 3kW immersion
heaters which are BEAB approved for safety as
recommended by the Electricity Council.
A high efficiency coil is positioned in the lower
part of the Stainless Lite vessel to ensure
maximum benefit of solar gain energy.
Stainless Lite direct models are listed in
Table 1 on Page 6 & 7.

water storage cylinder and is provided with a
high efficiency internal primary coil which is
designed for use with a gas or oil boiler and
is suitable for both open vented and sealed

Note:
The cold supply elbow c/w drain tapping
must be fitted as shown in figs 1, 2, 3 and

the drain tapping and, providing the hose
runs below the lowest level of the cylinder,
then all the water contents can be drained
out by syphonic action. (The cold feed pipe
dips internally to the base of the cylinder.)
