IMPORTANT: If more than 0.5 litres of fluid is spilled, repeat steps 1-5

Remove the PR6/PR200 Valve and siphon
the entire contents of the Hartgard container
into the Closed Circuit using the ½” hose.

12

Water will flow from the PR6/PR200 Valve Port
during this operation
(4.5 litres for each container of Hartgard).

13

When the Hartgard container is empty, flush approx 1 litre
of clean water through the hose into the Collector
(to ensure all of the Hartgard has been siphoned into
the system), and refit the PR6/PR200 Valve to the Test Block.

14

Remove the hose from the Fill Assembly and
screw in the Fill Plug as quickly as possible
to minimise fluid spillage.

IMPORTANT: If more than 0.5 litres of fluid is spilled, repeat steps 1-5
When charging the system using a PR200 Valve, pressurise the system until the PR200 Valve opens or until a pressure of
170kPa is read on the pressure gauge, whichever happens first.
When charging the system using a PR6 Valve, pressurise the system until the PR6 Valve opens or until a pressure of 80kPa
is read on the pressure gauge, whichever happens first.

Pressurise the Closed Circuit to 80kPa/170kPa,
as appropriate, using the bicycle pump/portable compressor
and ensure there is no leak at the Fill Assembly.
Remove bicycle pump/portable compressor from Test Block.

16

Ensure that the pressure remains stable
for at least 10 minutes.

17

Release the pressure from the Closed Circuit by
removing the PR6/PR200 Valve from the Test Block.

18

Remove the Test Block from the Tank.

19

Fit the PR6/PR200 Valve to the Jacket Relief Valve Port
when ready or as soon as water starts to be expelled
(440 systems).
The closed circuit system is now ready for operation.

20

Remove the solar collector packaging. This must be removed completely prior to the permanent operation of the water
heater.
