7. Connect Temperature Sensor Leads
The hot (longer) temperature sensor lead should be fitted into the
air bleed / hot sensor lead assembly at the collector hot return
connection as shown on page 33. It must be sealed in place
with thermoplastic putty or silicone.
Run the lead down the solar return pipe and connect it to the
connection within the pump and controller assembly as shown in
the diagram. Ensure the lead is protected from light.
The cold (shorter) temperature sensor lead should be fitted as
shown in the relevant diagram on pages 50 to 53.
Ensure the lead is protected from light. It must be sealed in place
with thermoplastic putty or silicone. The plug is then connected
to the pump and controller assembly as shown in the diagram.
Replace Pump Assembly Cover.
IT IS IMPORTANT THAT THESE PROBES ARE INSTALLED AS SPECIFIED. FAILURE TO DO SO
WILL LEAD TO MALFUNCTION OR LACK OF HOT WATER
NOTE
8. Cold Water Supply
Connect cold water supply to the inlet 'T'. Ensure that the relevant valves as described in the section 'Valves
and Fittings' on page 24. are fitted.
Purge the cold water supply lines to remove air and swarf before final connection.
9. Relief Drain Lines
Independent 15 mm copper pipes must be fitted to the drain outlets of the PTR and ECV. Each pipe must
be open to atmosphere and run with a continual downward grade in a frost free environment to a visible
discharge point. Drain lines must not exceed 9 metres in length.
Valves or other restrictions must not be placed in the relief valve drain outlet line.
Some water will drip from the drain lines during heating of the water in the storage cylinder. It is
recommended to discharge directly above a drain.
NOTE
10. Hot Water Discharge
Connect the hot water outlet of the storage cylinder to the pipe work supplying hot water to the premises.
A temperature limiting device may be required as detailed in the section 'Hot Water Delivery
Temperature' on page 22.
WARNING
11. Connect to Electrical Supply
Twin element storage cylinders are wired for non simultaneous operation. The electric supply should be 'Off-Peak'
(overnight) to the bottom heating unit and continuous to the top heating unit.
The power supply to a single lower element model should be Off-Peak (overnight).
The power supply to the element of the solar storage cylinder can be Off-Peak (overnight), extended Off-Peak
(overnight and day) or continuous or other tariffs available from the local electricity supply authority.
Rinnai strongly recommends the use of an Off-Peak tariff to ensure that solar heating takes priority over electrical
heating. If this isn't available, then a timer can be used to limit electrical heating to non solar hours.
