HEALTH & SAFETY

TH & SAFETY

IMPORTANT

The final fill of the heating system
should include the correct dose of a
suitable scale/corrosion inhibitor.

Note
Testing the RCD will not affect the operation
of the Electrastream Control Unit.

The Electrastream system should have a routine service at least once in 12 months.

IMPORTANT Always turn off the heating system and electricity supply to
the Electrastream before removing covers and working on the
Electrastream System - this includes the room thermostat cover.

6-1.1 Service Procedure

Confirm with the customer the unit’s service history and locate Benchmark Logbook.

Check cylinder model and serial number is listed in the Benchmark Logbook.

Visually inspect cylinder/s and vessels for damage, metal failure and signs of leaks.

Visually inspect all Electrastream pipework for damage, metal failure and signs of
leaks.

Set control unit to midnight to run self test and check Electrastream control unit for
error messages (see fig. 2-2a).

Record mains pressure, system pressure and heating operating pressure.

Turn the heating OFF at Electrastream Control Unit.

Turn the electrical supply to the Electrastream OFF at the isolating switch.

Momentarily open the combination TPR Valve and check that the water drains freely
and safely to and from the tundish.

10. Open combination PRV momentarily and close, valve should shut off. Repeat if

valve sticks. If valve will not shut off replace valve.

11. Open heating TPRV momentarily and close, valve should shut off. Repeat if valve

sticks. If valve will not shut off replace valve.

12. Close the Stop Cock.
13. Open the hot and cold taps, attach a hose to the cylinder drain cocks and empty the

system.

14. Remove tri-core heater, remove limescale and examine the element and seal. Refit

if in good condition.
In hard water areas it is probably better to replace the tri-core heater if heavily
scaled. Fit tri-core heater and seal.

15. Clean and check the in-line strainer in the combination valve - replace if required.
16. Check strainers and operation of mixing valve, see 4-3.10.
17. Close all drain cocks and refill system.
18. Check that no water is passing through the Combination Valve or the Pressure Relief

Valves, this will be evident at the Tundish.

19. Switch on the Electrastream isolator, set timer for midnight then set Control Unit and

room thermostat for heat.

20. Wait for the system to self check and heat up.
21. Check temperature of hot tap water, adjust as required, max. 60°C.
22. Check for leaks and bleed system again when the system is up to temperature.
23. Check operation of room thermostat and timer.
24. Check the RCD operation.
25. Enter details of service into the Benchmark Logbook.
