ABOUT YOUR WATER HEATER WATER HEATER APPLICATION This water heater is designed for use in a single family domestic dwelling for the purpose of heating potable water. Its use in an application other than this may shorten its life. MODEL TYPE Your Rheem® air sourced split heat pump storage tank is suitable for indoor or outdoor installation and the heat pump module designed for outdoor installation only. The model you have chosen is a 561 series model.
ABOUT YOUR WATER HEATER FREEZE PROTECTION The water heater has a freeze protection system. The freeze protection system will protect the water heater from damage, by preventing ice forming in the waterways of the water heater, in the event of freezing conditions occurring. If the ambient air temperature falls below 4°C and the heat pump module is not operating, the system will operate the circulator periodically.
ABOUT YOUR WATER HEATER WARNING This water heater is only intended to be operated by persons who have the experience or the knowledge and the capabilities to do so. This water heater 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 water heater.
ABOUT YOUR WATER HEATER OPERATING MODE MONITOR An operating mode monitor is located on the front of the heat pump module and houses a green and a red LED. The green LED, marked “NORMAL”, indicates the current operating mode of the heat pump water heater and the red LED, marked “ATTENTION”, indicates a fault mode. The green LED will emit either a constant glow or a series of flashes, with a 2 second interval between each series. A series of long green flashes may also be emitted.
ABOUT YOUR WATER HEATER Possible fault condition There may be a fault condition with the water heater if either: there is power available at the water heater and the green LED is off Before phoning to arrange a service inspection due to the green LED being off, refer to “Heat Pump Is Not Operating” on page 16 in the “Save A Service Call” section of this Owner‟s Guide.
ABOUT YOUR WATER HEATER TO TURN ON THE WATER HEATER Open the cold water isolation valve fully on the cold water line to the water heater. Switch on the electrical supply at the isolating switch to the water heater. Note: When power is turned on or reconnected to the water heater, the red LED will emit a solid glow for three (3) seconds and then extinguish. This is normal operation and does not indicate a fault. The LED display will then return to the current operational status.
ABOUT YOUR WATER HEATER VICTORIAN CUSTOMERS Notice to Victorian Customers from the Victorian Plumbing Industry Commission. This water heater must be installed by a licensed person as required by the Victorian Building Act 1993. Only a licensed person will give you a Compliance Certificate, showing that the work complies with all the relevant Standards. Only a licensed person will have insurance protecting their workmanship for 6 years.
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 18).
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 CAUTION If the water supply has a TDS greater than 150 mg/L and a green anode has not been changed to a black anode, or if the TDS is greater than 600 mg/L and the anode has not been changed to a blue anode, there is the possibility the anode may become overactive and hydrogen gas could accumulate in the top of the water heater during long periods of no use. In areas where this is likely to occur, the installer should instruct the householder on how to dissipate the gas safely.
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) Is the electricity switched on? Inspect the isolating switch marked “HOT WATER” or “WATER HEATER” at the switchboard and the isolating switch (if one is installed) at the water heater and ensure they are turned on.
SAVE A SERVICE CALL HEAT PUMP IS NOT OPERATING There must be power available at the water heater and to the heat pump for the heat pump to operate and for the LEDs to glow or flash. Time controlled power supply (no power at the water heater) If the water heater is connected to a time controlled power supply, then during periods of no power supply at the water heater the LEDs will be off. This is not a fault condition, but a result of no power being available to energise the LEDs.
SAVE A SERVICE CALL Fault Mode – 4, 5, 9 red LED flashes In backup heating mode with a fault mode of either a four (4), five (5) or nine (9) series of red flashes, the water is heated to a temperature of 60°C.
SAVE A SERVICE CALL Green LED is off There may be a fault condition with the heat pump if there is power available at the water heater and the green LED is off.
SAVE A SERVICE CALL HIGHER THAN EXPECTED ELECTRICITY BILLS With the installation of your air sourced split heat pump water heater, maximum electrical energy savings can be achieved.

INSTALLATION STANDARDS 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/NZS 3000 and all local codes and regulatory authority requirements. In New Zealand, the installation must also conform with Clause G12 of the New Zealand Building Code.
INSTALLATION WATER HEATER LOCATION The storage tank is suitable for either outdoor or indoor installation. Whether located outdoor or indoor, the heat pump storage tank should be installed close to the most frequently used outlet and its position chosen with safety and service in mind. The heat pump module is suitable for outdoor installation only. The heat pump module‟s position is to be chosen with noise, safety and service in mind.
INSTALLATION SAFE TRAY Where damage to property can occur in the event of the water heater leaking, the water heater must be installed in a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4 and all local codes and regulatory authority requirements. AS/NZS 3500.4 also has particular requirements as to when a safe tray must be installed. FREEZE PROTECTION The water heater has a freeze protection system.
INSTALLATION 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 area such as a bathroom or ensuite, to reduce the risk of scalding. The installing plumber may have a legal obligation to ensure the installation of this water heater meets the delivery water temperature requirements of AS/NZS 3500.
INSTALLATION CIRCULATED HOT WATER FLOW AND RETURN SYSTEM A 561 series heat pump water heater should not be installed as part of a circulated hot water flow and return system in a building. If a circulated flow and return system is required, it is necessary to bypass the heat pump water heater and install a secondary water heater connected to the hot water flow and return line and supplied from the heat pump water heater.
INSTALLATION ANODE TYPES The vitreous enamel lined cylinder of the water heater is only covered by the Rheem warranty when the total dissolved solids (TDS) content in the water is less than 2500 mg/L and when the correct colour coded anode is used. If an incorrect colour coded anode is used in the water heater, any resultant faults will not be covered by the Rheem warranty. In addition, the use of an incorrect colour coded anode may shorten the life of the storage tank.
