COMMISSIONING

6.1 TORRENT DIRECT MODELS
(a) Ensure that the thermal store is filled with water to the water level mark inside the feed
and expansion cistern and the ball valve (if fitted) is adjusted correctly.
If the ball valve is fitted turn down the service valve once the system is finally filled to the
point where the warning/overflow pipe will cope with the discharge arising from a ball
valve failure.
(b) Switch the immersion heater on and allow the store to heat up to full temperature (typically
o
75 – 77 C).
(c) When the store has been fully charged, open the nearest hot tap and check that the
mixing valve at the Torrent unit is delivering the desired temperature of 55±5
factory set value. Adjust if necessary to suit individual requirements.
(d) Instruct the occupant on how to use the off-peak timer (if fitted) and the appliance.
(e) Fill in and sign the 'Benchmark' document and leave it and the appliance manual at
suitable place near the appliance.
(f) Electrician/Installer: Please note that the water at the hot tap does not indicate that the
Torrent is full. Check that there is water in the feed and expansion cistern before switching
on the immersion heaters. Dry firing the elements will cause premature failure which is not
covered by our warranty.
6.2 NON-ELECTRIC TORRENT MODELS
(a) Open the incoming stop valve and fill the domestic hot water system. For open vented
heating system, fill the whole of the primary heating system and the thermal store with
potable water through the feed and expansion cistern. For sealed heating system fill the
thermal store with potable water through the feed and expansion cistern and the heating
system to the design pressure using the filling loop.
(b) Check the water level in the feed and expansion cistern and adjust the ball valve if
necessary. Check the whole of the primary heating an domestic hot and cold distribution
system, including the Torrent for leaks.
(c) It is essential that all systems function properly for optimum performance and to achieve
this:-
The primary system should be commissioned in accordance with good practice and
generally in accordance with the requirements of BS 6798, BS 5449 and BS 7593. Full
details of the requirements are given in PAS 33:1999 under section 10 Commissioning.
The boiler manufacturers instructions should be followed during the commissioning
phase.
If solar thermal system is fitted it should be commissioned as per manufacturers
instructions.
