ABOUT YOUR WATER HEATER MAINS PRESSURE The water heater is designed to operate at mains pressure by connecting directly to the mains water supply. If the mains supply pressure in your area exceeds that shown on page 23, a pressure limiting valve must be fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved. PRECAUTIONS Where damage to property can occur in the event of the water heater leaking, the water heater must be installed in a safe tray.
ABOUT YOUR WATER HEATER HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY? Installation requirements are shown on pages 21 to 28. The water heater must be installed: by a qualified person, and in accordance with the installation instructions, and in compliance with Standards AS/NZS 3500.4, AS 5601 or AS/NZS 5601.1, as applicable under local regulations, and all local codes and regulatory authority requirements.
REGULAR CARE ANNUAL SERVICE For safe and efficient operation, it is recommended an annual service be conducted on the water heater. Warning: Servicing of a water heater must only be carried out by qualified personnel. Phone Rheem Service or their nearest Accredited Service Agent. Note: The annual service and routine replacement of any components, if required, are not included in the Rheem warranty. A charge will be made for this work. Only genuine replacement parts should be used on this water heater.
REGULAR CARE MAJOR FIVE YEAR SERVICE It is recommended a major five year service be conducted on the water heater. Warning: Servicing of a water heater must only be carried out by qualified personnel. Phone Rheem Service or their nearest Accredited Service Agent. Note: The five year service and routine replacement of any components, such as the anode and relief valve(s), are not included in the Rheem warranty. A charge will be made for this work.
REGULAR CARE MINOR SIX MONTH MAINTENANCE It is recommended minor maintenance be performed every six months by the dwelling occupant. The minor maintenance includes: Operate the easing lever on the temperature pressure relief valve. It is very important you raise and lower the lever gently. Refer to “Temperature Pressure Relief Valve” on page 12. Warning: Exercise care to avoid any splashing of water, as water discharged from the drain line will be hot.
REGULAR CARE TEMPERATURE PRESSURE RELIEF VALVE This valve is near the top of the water heater and is essential for its safe operation. It is possible for the valve to release a little water through the drain line during each heating period. This occurs as the water is heated and expands by approximately 1/50 of its volume. Continuous leakage of water from the valve and its drain line may indicate a problem with the water heater (refer to “Temperature Pressure Relief Valve Running” on page 19).
REGULAR CARE TEMPERATURE LIMITING VALVE A RheemPlus water heater is fitted with a temperature limiting valve at the hot water outlet. The valve is set to deliver water not exceeding 50°C. The valve should be checked for performance every twelve months. This can be performed by measuring the water temperature from the hot tap nearest to the water heater with a thermometer.
WATER SUPPLIES This water heater must be installed in accordance with this advice to be covered by the Rheem 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. If you are unsure of your water chemistry, you may be able to obtain information from your local water supply authority.

WATER SUPPLIES SATURATION INDEX The saturation index (SI) is used as a measure of the water‟s corrosive or scaling properties. In a corrosive water supply, the water can attack copper parts and cause them to fail. In a scaling water supply calcium carbonate is deposited out of the water onto any hot metallic surface. Where the saturation index exceeds +0.40, the water is very scaling.
WATER SUPPLIES CHANGE OF WATER SUPPLY The changing or alternating from one water supply to another can have a detrimental effect on the operation and / or life expectation of a water heater cylinder and a temperature pressure relief valve. Where there is a changeover from one water supply to another, e.g.
SAVE A SERVICE CALL Check the items below before making a service call. You will be charged for attending to any condition or fault that is not related to manufacture or failure of a part. NOT ENOUGH HOT WATER (OR NO HOT WATER) Are you using more hot water than you think? Is one outlet (especially the shower) using more hot water than you think? Very often it is not realised the amount of hot water used, particularly when showering. Carefully review the family‟s hot water usage.
SAVE A SERVICE CALL WATER NOT HOT ENOUGH You may find that due to heavy hot water usage the water temperature may be lower than normally expected. WATER TEMPERATURE TOO HIGH A RheemPlus water heater is fitted with a temperature limiting valve set to deliver water not exceeding 50°C. If the water is being delivered at a temperature exceeding 50°C, phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.
