Starting Up
Filling the Tank
Condition(s):
Tank flushed with fresh water.
Filling procedure:
DHW Tank:
1.
Connect the cold water circuit to the distribu-
tion network outlet.
2.
Make sure that the isolating valve of the cir-
cuit is open
3.
Open a hot water draw-off tap at a high point
in the system
4.
Once the air is purged and the flow has sta-
bilised at the tap, close the tap.
Primary tank:
1.
Fill the primary circuit through the primary cir-
cuit supply connection (inlet).
2.
Bleed the air from the primary tank and re-
peat water filling until you reach 1,0 bar to
1,5 bar. Take care not to exceed 1,5 bar.
Follow-on Task(s):
î
Check that there are no leaks
î
Start the boiler as required. Refer to the
Start-
up
procedure opposite.
Always fill and pressurise the inner
tank (DHW) before filling the outer
(primary) tank. Failure to comply may
damage the inner tank.
Condition(s):
Start-up procedure:
1.
Turn on the heat generator connected to the
tank.
2.
Allow the tank to heat up and reach set tem-
perature.
3.
Run water from a hot draw-off tap and adjust
DHW thermostatic mixing valve to a suitable
temperature (Minimum supply temperature
60° on systems with a pumped return).
Follow-on Task(s):
Check that there are no leaks.
As the tank is connected to a heat
generator (e.g. a boiler), the DHW de-
mand will be generated through the
heat generator controller. Please refer
to the heat generator technical manual
for the correct start-up procedure.
