BEFORE STARTING THE INSTALLATION OF THE ELECTRASTREAM CHECK ALL COMPONENTS HAVE
BEEN DELIVERED AND ARE IN SATISFACTORY CONDITION - Refer to 1-3 .
H Indirect cylinder coils may be fractured, consult GAH (HEATING PRODUCTS).
H *Check to make sure there is air charge pressure in the accumulator. If air is not
present, suspect faulty accumulator. Consult GAH (HEATING PRODUCTS).

Turn off the system at the isolator or consumer unit.
G
Turn on a hot tap until it runs cold to reduce the pressure and temperature.
G
Turn on the radiators - ensuring all thermostatic valves are open.

H Check there are no restrictions in the hot water pipework.
H Check for loss of pressure in the hot water expansion vessel.
H Check for loss of pressure in the heating expansion vessel.
H Check pressure reducing valve (on combination valve, see 4-3.3).
H Check for back feed of high mains pressure from expansion valve.
H The heating system should not be run with all the radiators turned off unless there is
a bypass valve in the system, see figs. 1-2a and 1-2b.
H Check for air in the heating system.
H Check that the cylinder temperature sensor has not been dislodged from the phial in
the cylinder.
H With the heating elements and heating pump turned OFF, check for error messages
on the Electrastream Control Unit.
H With the heating elements and heating pump turned OFF, check the target
temperature of the Electrastream Control Unit (see step 8, fig. 2-2b).
H With the heating elements and heating pump turned OFF, check for error messages
on the Electrastream Control Unit.
