❍ Indirect cylinder coils may be fractured, consult GAH (HEATING PRODUCTS).

❍ *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.

● Turn on a hot tap until it runs cold to reduce the pressure and temperature.

● Turn on the radiators - ensuring all thermostatic valves are open.

● Contact the installer.

❍ Check there are no restrictions in the hot water pipework.

❍ Check for loss of pressure in the hot water expansion vessel.

❍ Check for loss of pressure in the heating expansion vessel.

❍ Check pressure reducing valve (on combination valve, see 4-3.3).

❍ Check for back feed of high mains pressure from expansion valve.

❍ 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.

❍ Check for air in the heating system.

❍ Check that the cylinder temperature sensor has not been dislodged from the phial in

the cylinder.

❍ With the heating elements and heating pump turned OFF, check for error messages

on the Electrastream Control Unit.

❍ With the heating elements and heating pump turned OFF, check the target

temperature of the Electrastream Control Unit (see step 8, fig. 2-2b).

❍ With the heating elements and heating pump turned OFF, check for error messages

on the Electrastream Control Unit.
