7 COMMISSIONING & CUSTOMER HAND OVER

7.1 Commissioning

When all connections have been completed the solar water heater can be ﬁlled with

water.

1. Before turning on the cold water supply to the system, open one hot tap within the

household to release air from the system during the ﬁlling process. Do not leave

the open tap unattended during the ﬁlling process.

2. Turn on the cold water supply and wait for the system to ﬁll.

3. When water ﬂows from the open hot tap without air bursts then the hot tap can be

closed. This will now pressurise the solar water heater system.

4. Once the system is pressurised, all connections on the water heater must be

checked for leaks and repaired if necessary.

5. When the system is proven water tight, power and/or gas can be applied to the

AES system.

6. To test that the element is operational turn the circuit breaker in the switch board

on and off, you should see the power meters speed change during this action.

7. For gas AES systems, turn on a hot water tap and the gas heater will ignite

provided the water temperature is less than 60 °C.

7.2 Filling & Commissioning the Closed Circuit Jacket

When ﬁlling the jacket with glycol it is essential that the main tank is ﬁlled with water and

pressurised prior to ﬁlling the closed circuit. Refer to section 7.1 above.

Do not ﬁll the closed circuit system with any toxic solution. Only use the solar transfer

ﬂuid as speciﬁed by your TS system distributor. There is a real risk to public health if the

wrong solar glycol solution is used.

The solar transfer ﬂuid is of food grade and non-toxic. However, care must be taken

when handling not to spill or accidentally consume. Always use the solar transfer ﬂuid as

speciﬁed and outlined in section 7.2.1 below.

7.2.1 Approved Solar Transfer Fluids

Name: ST-5 Solar Transfer Fluid

above 40% of solution:

1. TS 180/C system: 1 bottle 4.5 litres total

2. TS 300/C system: 2 bottles 9 litres total
