4.1. Connections
All pipework connections to the cylinder MUST be made in accordance with Figure 2. A
drain cock (not supplied) should be fitted in the position shown in Figure 2 to facilitate
draining of the cylinder.
4.2. Electrical fittings
The electrical fittings (Figure 2) must be fitted to the product. If not, the guarantee will be
invalid. Check the T/P Relief Valve (Figure 2) to ensure it is connected with the electrical
fittings. If not, please contact us by telephoning 0203 321 5929.
4.3. Cold water supply
For best results, the cylinder should be fed by an uninterrupted supply pipe into the
pressure reducing valve (PRV) (Figure 2) with a maximum supply pressure of 0.9 MPa. The
cylinder should not be used on any system with a supply pressure below 0.15 MPa and a
flow rate of less than 20 litres per minute.
