3.4 SOLAR CYLINDER DESCRIPTION - Figs. 4
Positioning
The SolarSmart 100 cylinder must be installed on a flat vertical wall which is capable of supporting the weight of the cylinder
when full (140 kg).
The cylinder may be installed in any room or internal frost free space, although particular attention is drawn to the
requirements of the current IEE Wiring (BS7671) Regulations, and in Scotland, the electrical provisions of the Building
Regulations applicable in Scotland, with respect to the installation of the cylinder in a room or internal space containing a
bath or shower. When the cylinder is installed in a room containing a bath or shower, it must not be possible for a person
using the bath or shower to touch any electrical switch or cylinder control utilizing mains electricity.
The bottom of the solar cylinder must be located within 6 metres vertically of the top of the drain back unit.

Water connections

Note:
Use compression fittings only on the cylinder connections. Use a minimum of 1 metre of copper pipe from the cylinder
for the domestic water inlet and outlet connections.
As it is a requirement that the discharge pipe must fall at least
300 mm directly from the tundish we recommend that it is
moved towards the rear wall using a suitable length of 15 mm
pipe and a ½" to 15 mm adaptor.
