Pump Isolation Valve (Procedure 16)
Ensure any escaping solar circuit fluid is contained and does not enter any
part of a rainwater tank system as entry will render the water undrinkable.
1. Remove the solar circuit relief valve by following steps 1 – 6 in procedure 2. This will
relieve the solar circuit pressure. Note: ensure all warnings in procedure 2 are
observed and adhered to.
2. Attach one end of a ½” flexible hose to heat exchanger drain valve and insert the other
end into a clean container.
3. Open heat exchanger drain valve by rotating 90º in an anti clockwise direction. Solar
circuit fluid will now drain into the container. Note: approximately 16 litres of fluid will
drain out of the heat exchanger. When all fluid has been drained close drain valve by
rotating 90º in a clockwise direction and remove ½” hose.
4. Unscrew pump isolation valve nut and olive and pull out pump pipe work from valve.
Note: A small amount of solar circuit fluid will drain from heat exchanger pipe work.
5. Unscrew and remove pump isolation valve from heat exchanger pipe work.
6. Unscrew and remove male upper half of nut and olive connection from isolation valve
and screw into replacement isolation valve using thread tape.
7. Screw replacement isolation valve into heat exchanger pipe work and insert pump pipe
work into isolation valve and tighten nut and olive.
10. Open pump isolation valve (if closed) and pour solar circuit fluid into solar relief valve
opening and complete solar circuit relief valve reassembly in reverse order of
procedure 2 steps 1 – 6.
11. Restore power and water supplies and check for leaks.
12. If fluid was lost, recommission appliance to check solar circuit fluid level (refer to
‘Commissioning Procedure’ in ‘Owners Guide & Installation Instructions’).
Tempering Valve – 596 Models Only (Procedure 17)
A quantity of hot water may discharge from gas booster & hot pipe during this
procedure. Wear Personal Protective Equipment to prevent scalds or burns.
1. Isolate power and water supplies to the water heater.
2. Relieve pressure from the water heater through the T&PR valve or a hot tap.
3. Unscrew the tempered water pipe work union at the tempering valve elbow.
4. Unscrew the tempering valve hot and cold water unions and remove tempering valve.
5. Unscrew and remove elbow from tempering valve.
6. Complete reassembly in reverse order of above.
Removing or Replacing an S200 or T200 Series Solar Collector (Procedure 18)
1. Remove the solar circuit relief valve by following steps 1 – 6 in procedure 2. This will
relieve the solar circuit pressure. Note: ensure all warnings in procedure 2 are
observed and adhered to.
2. Disconnect the hot and cold pipes at the collector(s) by unscrewing pipe unions at
collector(s) and pulling pipe work from collector(s).
3. Unscrew the collector inter-connector unions (if more than one collector) at the top and
bottom of the collectors. Do not stand on the collectors.
4. Remove the clamp screws retaining the collector to the angle bracket clamps,
disconnect the retaining strap at the top of the collector, slide the collector(s) out and
remove to ground level.
5. Complete collector and solar circuit relief valve assembly in reverse order of above.
6. Restore power and water supplies, check operation and check for leaks.
