Page 12: Regular Care
Have any trees trimmed which may shade the solar collectors. Rheem solar collectors have passed the AS/NZS 2712 requirements for resistance to hailstone damage, so it is not normally necessary to fit a guard to a collector. Stone Guards are available to provide a level of protection to the collectors against vandalism or accidental damage. - Page 13 REGULAR CARE FLUSHING THE SOLAR COLLECTORS It may be necessary to flush the solar collectors if there is sediment in the water supply. This should be conducted in the morning, within three hours of sunrise. To flush the solar collectors: ...

WATER SUPPLIES This water heater must be installed in accordance with this advice to be covered by the warranty. This water heater is manufactured to suit the water conditions of most public reticulated water supplies. However, there are some known water chemistries which can have detrimental effects on the water heater and its operation and / or life expectancy. - Page 15 Refer to the Saturation Index chart on page 16. Contact Rheem Service or their nearest Accredited Service Agent if a replacement heating unit is required. Refer to the cold water connection detail on page 35 for the position of the expansion control valve.

Switch off the electrical supply at the power outlet to the solar control unit for a few seconds, then switch on again. If the green LED remains off or the red LED recommences to flash, then count the number of flashes and phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection. Collectors shaded If trees or other objects shade the solar collectors or if the glass is dirty, the effectiveness of the solar collectors will be greatly reduced. - Page 18 Heavy flows of hot water until the water heater is cold - then stops until water reheats The water heater must be switched off at the isolating switch or switchboard. Phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.
- Page 19 Warning: No attempt should be made to remove or replace broken collector glass. The collector glass is not offered as a replacement part. Should the solar collector require replacement, contact Rheem Service or their nearest Accredited Service Agent. HIGHER THAN EXPECTED ELECTRICITY BILLS With the installation of your new solar hot water system, maximum electrical energy savings can be achieved with careful planning of hot water usage.

INSTALLATION – SOLAR STORAGE TANK THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING. The system is suitable for installation with Rheem NPT 200 or HBT 200 solar collectors. The system is not suitable for installation above 400 metres altitude. - Page 21 INSTALLATION – SOLAR STORAGE TANK WATER HEATER APPLICATION This water heater is designed to be installed as an electric boosted solar water heater with its booster heating unit connected to a power supply, however it may be installed with an in-series continuous flow or storage booster.
- Page 22 INSTALLATION – SOLAR STORAGE TANK MAINS WATER SUPPLY Where the mains water supply pressure exceeds that shown in the table, an approved pressure limiting valve is required and should be fitted as shown in the installation diagram (refer to diagram on page 35).
- Page 23 INSTALLATION – SOLAR STORAGE TANK HOT WATER DELIVERY This water heater can deliver water at temperatures which can cause scalding. It is necessary and we recommend that a temperature limiting device be fitted between the water heater and the hot water outlets in any ablution and public areas such as a bathroom, ensuite or public amenities, to reduce the risk of scalding.
- Page 24 INSTALLATION – SOLAR STORAGE TANK CIRCULATED HOT WATER FLOW AND RETURN SYSTEM A solar water heater should not be installed as part of a circulated hot water flow and return system in a building. The benefits of solar gain will be significantly reduced and energy gained from the sun lost through the pipe work.
- Page 25 INSTALLATION – SOLAR STORAGE TANK REDUCING HEAT LOSSES The cold water line to and the hot water line from the water heater must be insulated in accordance with the requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed. The full length of the solar hot and solar cold pipes between the solar storage tank and the solar collectors MUST BE insulated.

For reasons of safety and economy, we advise the thermostat be set at the lowest temperature that will provide sufficient hot water during periods when boosting is required. Rheem recommends the thermostat is set at 60°C to maximise solar contribution. Discuss the thermostat setting requirements with the householder. - Page 39 CONNECTIONS – ELECTRICAL BOOSTER CONTROL The isolating switch installed in the electrical meter box for the solar storage tank should be left switched on. Leaving the isolating switch switched on will also provide a sufficient period of time each day for the booster heating unit to operate, if required, to satisfy the requirements of AS 3498.
