3.4.7 PIPEWORK, FITTINGS AND OUTLET / TERMINAL FITTINGS
All pipework, fittings and terminal fittings must be compatible with unvented systems and
have a rated operating pressure of at least 6 bar. Where plastic pipe / fittings are being used
the rated pressure must be achievable at outlet temperatures that can be expected within the
hot water distribution pipework. If in doubt, consult the manufacturer of the fittings selected.
3.4.8 SECONDARY CIRCULATION
Secondary circulation is not recommended for the Electromax Solar as it is intended for off
peak electrical operation. Circulating the stored water would gradually cool the Electromax
Solar to an unacceptable temperature during off peak periods.
