7.2.3 Procedure
Ensure the Collectors are fully covered for this procedure to prevent pressure variation
occurring due to thermal activity in the collectors.
1. Remove the 100 kPa jacket relief valve from the
tank socket. Refer to Figure 6.11 on page 20 for
the location of this valve.
2. Connect the ½” ( 15 mm ) flexible hose to the fill tap
located at the b o tt o m left side of the collector
array. Refer to Figure 6.9 on page 20 for the
location of this fitting. Open the tap using the
square key.
3. With the aid of a funnel and hose connected to
the fill tap, pour the contents of the heat transfer
fluid container/s into the funnel.
4. Once competed, add drinking grade water until
the fluid flows from the 100 kPa jacket relief valve
socket in the tank. Close the fill tap.
5. Insert the pressure test block into the tank’s 100
kPa jacket relief valve socket.
6. Using a bicycle pump or similar connected to
the pressure test block to pressurise the system
to 120 kPa (Figure 7.2).
7. Check over a 10 minute period that the pressure
on the test gauge remains unchanged and the
fittings are free from any evidence of leaks.
8. Once the circuit is free from leaks, release the
pressure in the system through the pressure test
block valve fitting.
9. Unscrew the pressure test block from the jacket
relief valve tank socket.
10. Refit the 100 kPa jacket relief valve into the tank
socket.
11. The system is now operational and the covers
can be removed from the collectors.
7.3 Customer Hand Over
The solar water heater is now fully operational.
Once the solar water heater is commissioned and you are confident it is operating
correctly, complete the installation details on the carbon copy sheet at the beginning of
the Owner’s Manual. Please remove the Conergy (blue) and the installer (pink) copy.
Please hand the owner the Owner’s Manual and Gas Heater Manual (if gas AES is used).
Before leaving the installation, ensure that the customer is fully aware of the systems
operation and whom to contact should there be any questions in the future.
Thank you for installing our world class Conergy solar water heater.
