ABOUT YOUR STORAGE TANK STORAGE TANK APPLICATION This storage tank is designed for the purpose of storing heated potable water. Its use in an application other than this may shorten its life. MODEL TYPE ® The Rheem Commercial hot water storage tank you have chosen can be installed indoor or outdoor and is either a 610 340 or 610 430 model. Water is stored in a vitreous enamel lined steel cylinder and heated by an external primary heating source.
ABOUT YOUR STORAGE TANK WARNING This storage tank is only intended to be operated by persons who have the experience or the knowledge and the capabilities to do so. This storage tank is not intended to be operated by persons with reduced physical, sensory or mental capabilities i.e. the infirm, or by children. Children should be supervised to ensure they do not interfere with the storage tank. SAFETY This storage tank is supplied with a combination temperature pressure relief valve.
ABOUT YOUR STORAGE TANK HOW DO I KNOW IF THE STORAGE TANK IS INSTALLED CORRECTLY? Installation requirements are shown on pages 13 to 19 and 24 to 29. The storage tank must be installed: by a qualified person, and in accordance with the installation instructions, and in compliance with Standard AS/NZS 3500.4 and all local codes and regulatory authority requirements. In New Zealand the installation must also conform with the New Zealand Building Code.
REGULAR CARE MINOR SIX MONTH MAINTENANCE It is recommended minor maintenance be performed every six months by a responsible officer. 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 8. 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 storage tank 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 12).
WATER SUPPLIES This storage tank must be installed in accordance with this advice to be covered by the Rheem warranty. This storage tank 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 storage tank 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 ANODE INSPECTION AND REPLACEMENT The anode installed in your storage tank will slowly dissipate whilst protecting the cylinder. The life of the cylinder may be extended by replacing the anode. If the anode is not replaced during a five year service (refer to “Major Five Year Service” on page 7) then the maximum time after installation when the anode should be replaced for this storage tank is 8 years.
WATER SUPPLIES SUMMARY OF WATER CHEMISTRY ADVICE AFFECTING WARRANTY The storage tank and its components are not suitable for certain water chemistries. Those chemistries are listed below.
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? Are outlets (especially the showers) 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 hot water usage.
INSTALLATION THIS STORAGE TANK IS NOT SUITABLE FOR POOL HEATING INSTALLATION STANDARDS The storage tank must be installed: by a qualified person, and in accordance with the installation instructions, and in compliance with Standard AS/NZS 3500.4 and all local codes and regulatory authority requirements. In New Zealand the installation must also conform with the New Zealand Building Code. All packaging materials must be removed from the storage tank prior to its installation.
INSTALLATION Note: The storage tank should not be placed in direct contact with a concrete surface that is less than two months old and not fully cured as this may attack the metal coating of the storage tank base. A moisture barrier should be used between the two surfaces in this instance. Remember all local authorities have regulations about putting storage tanks into roof spaces. For a single storage tank installation, follow the diagram on page 19.
INSTALLATION HOT WATER DELIVERY This storage tank can deliver water at temperatures which can cause scalding. It is necessary and we recommend that a temperature limiting device be fitted between the storage tank and the hot water outlets in any ablution and public areas such as bathrooms, ensuites or public amenities to reduce the risk of scalding.
INSTALLATION CIRCULATED HOT WATER FLOW AND RETURN SYSTEM If a storage tank is used with a primary water heating source and is to be installed as part of a circulated hot water flow and return system, the primary heating source must be able to provide a hot water outlet temperature of at least 60°C. Note: The thermostat must always be set to at least 60°C. Refer to the diagram on page 16.
INSTALLATION REDUCING HEAT LOSSES The cold water line to, primary flow and return lines and the hot water line from the storage tank must be insulated in accordance with the requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed. Keep temperature settings down. Lower temperatures reduce heat losses and prolong cylinder life. Do not set the controlling thermostats on the primary heating plant above 70°C unless it is necessary.

CONNECTIONS – PLUMBING EXPANSION CONTROL VALVE Local regulations may make it mandatory to install an expansion control valve (ECV) in the cold water line to the storage tank. In other areas, an ECV is required if the saturation index is greater than +0.4 (refer to “Water Supplies” on page 9). The expansion control valve must always be installed after the non return valve and be the last valve installed prior to the storage tank (refer to diagram on page 20).
CONNECTIONS – PLUMBING WARNING: Plumber – Be Aware The primary flow and return pipes between the storage tank(s) and the primary water heating source, including the solar hot and solar cold pipes between the solar storage tank(s) and the solar collectors, MUST BE of copper. All compression fittings must use brass or copper olives. Plastic pipe MUST NOT be used, as it will not withstand the temperature of the water generated by the primary heating source under certain conditions.
CONNECTIONS – ELECTRICAL The power supply to the primary heating source and circulating pumps must not be switched on until the storage tank is filled with water and a satisfactory megger reading is obtained. No electrical connections are to be made on the storage tank, except if a remote thermostat is fitted. All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the Wiring Rules AS/NZS 3000 and all local codes and regulatory authority requirements.
MULTIPLE INSTALLATIONS A multiple installation of Rheem storage tanks on a single manifold or multiple manifolds is possible, using ® the Rheem Equa-Flow manifold system, where large volumes of hot water is required. The Equa-Flow principle will function with storage tanks in line, around a corner or in rows back to back (refer to the diagrams on page 25). The cold water and hot water manifolds must be designed to balance the flow from each storage tank.
