BEFORE STARTING THE INSTALLATION OF THE ELECTRASTREAM CHECK ALL COMPONENTS HAVE
BEEN DELIVERED AND ARE IN SATISFACTORY CONDITION - Refer to 1-3 .
The filling loop should be fitted between the incoming mains and the heating system
return as shown in figs. 1-2a, 1-2b and 4-4a. Locating the filling loop within site of the
pressure gauge is recommended, however if this is not practical an extra gauge can be
fitted adjacent to the filling loop.
When not in use one of the hose unions must be disconnected as there must not be a
permanent connection to the mains supply.
4-4.8 Motorized Valve
A 2 port motorised valve is supplied, this should be fitted in the heating flow from the
cylinder directly after the heating PRV take off and prior to any other take-offs. The valve
ols ols ols ols
is wired as shown in figs. 3-3a and 3-3b.
The valve is normally closed to prevent gravity feed from the cylinder to the heating
system, when the pump starts the valve opens.
4-4.9 Bypass (not supplied)
An automatic bypass valve should be fitted between the flow and return of the heating
system, normally after the pump but before any radiator take offs. The valve must be set
to suit the pressure of the system, refer to manufacturers instructions.
4-4.10 Room Thermostat (not supplied)
A standard room thermostat with no built in timers or functions is recommended, e.g.
Honeywell T6360B or equivalent.
