4-3.7 Pipework

When all pipework has been installed, disconnect from the Electrastream components
and flush all pipework thoroughly.
When connecting to existing pipework remove all unwanted components, create new pipe
runs then flush thoroughly before connecting to the Electrastream components.

4-3.8 Electrastream Components

All Electrastream components and pipework are checked at the factory prior to dispatch,
however always check the connections for leaks on commissioning as transportation and
installation can cause joints to move.

4-3.9 Hot Water TPRV

The temperature and pressure regulating valve (TPRV) fitted to the cylinder is to protect
the cylinder from overheating and/or over pressure.
The TPRV discharge must comply with Building Regulations G3 refer to pages 40-42.
The valve will open if the system hot water pressure exceeds 7 Bar ± 10%.
The valve will open if the system hot water temperature exceeds 90 to 95°C.
The valve can be manually opened by turning the green knob clockwise, to close
continue turning clockwise until it clicks.

4-3.10 Thermostatic Mixing Valve

A Thermostatic Mixing Valve is supplied with the Electrastream. It should be fitted
between the cylinder hot water outlet and the draw off (taps). The valve mixes hot water
from the cylinder with cold water to provide hot water at the taps at a consistent
temperature.
The valve is supplied with two check valves which must be fitted to the hot and cold
supply.
It is recommended to fit a full bore service valve on each of the three pipes to the valve.

IMPORTANT

Under no circumstances should the

system be operated without the

cylinder TPRV fitted and working

correctly. The cylinder tapping for

the TPRV must not be used for any

other purpose.

Notes
Refer to the mixing valve manufacturer’s instructions supplied with the valve for further information. Put
these with this manual.
The mixing valve is not guaranteed against corrosion or blockage caused by excessive scale - see
4-3.5.
