2. The solar collectors will gain a high level of heat during periods of solar radiation. If the

solar pump is activated during a period of high solar radiation and the solar collectors

have not been covered, the initial flow of closed circuit fluid will absorb this heat and a

rumbling sound may be heard. This is normal and the solar circuit will achieve a stable

operating condition once full flow through the solar circuit is established.

3. The solar pump is set on speed setting 3. This speed setting must not be adjusted.

The solar control unit automatically controls and adjusts the speed of the pump to

maximise solar contribution. Manual adjustment of the speed dial setting may result in

the system not operating correctly or efficiently.

Commissioning the Solar Circuit

To commission and check the solar circuit:

1. Switch off the electrical supply at the isolating switch to the solar storage tank.

If the pump has been operating, wait five minutes to allow the drain back of the closed

circuit fluid in the solar circuit.

2. Cover the solar collectors with an opaque material to prevent solar gain during the

commissioning process.

3. Remove the lower and upper front covers from the solar storage tank.

The solar monitor located on the pump access cover is

connected to the solar control module by a ribbon cable. The

ribbon cable has sufficient length to enable the removal of the

pump access cover and for it to be set to one side of the

opening without disconnecting the ribbon cable from the solar

control module.

The ribbon cable can be disconnected from the solar control

module if it is necessary to remove the pump access cover

completely from the work area in front of the solar storage

tank.

4. Ensure the isolation valve in the pipe work between the outlet

of the heat exchanger and the solar pump, located behind the

pump access cover of the solar storage tank, is fully open.

Attach Closed Circuit Fluid Level Hose

5. Attach the clear hose to the solar circuit.

To attach the hose:

• Ensure the heat exchanger drain valve is closed. The

heat exchanger drain valve is located adjacent to the

solar pump, behind the pump access cover of the solar

storage tank.

• Attach one end of the hose to the hose tail connection. It

may be necessary to secure the hose with a hose clamp.

• Plug the free end of the hose.

• Affix the hose securely in a vertical orientation to the

front of the solar storage tank using tape, adjacent to the

text, “MINIMUM FLUID LEVEL WITH PUMP

OPERATING”.
