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.

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.
Page 8
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”...

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.

At the end of the service life of the heat pump water heater and prior to the water heater being disposed of, a person qualified to work with refrigerants must recover the refrigerant from within the sealed system. The refrigerant must not be vented to atmosphere. Phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.
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. The major service includes: Replace the temperature pressure relief valve.

Where the pH is less than 6.0 the Rheem warranty does not apply to the water heater. pH is a measure of whether the water is alkaline or acid. In an acidic water supply, the water can attack stainless steel parts and cause them to fail.
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”...

If a series of two (2) flashes occurs, the heat pump will not switch to backup heating mode. Phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection. If a single flash or a series of three (3) to nine (9) flashes occurs, the water heater will switch to backup heating mode to ensure a supply of hot water.
Page 17
If the heat pump stops operating and the red LED recommences to flash, the fault condition which led to the red LED flashing may not have cleared and there may be a problem with the heat pump. Count the number of red flashes and phone Rheem Service or their nearest Accredited Service Agent to arrange for an inspection.

This water heater is recommended for connection to a 24 hour per day power supply. A Rheem heat pump water heater consumes less energy than an electric water heater. The impact on an electricity account will depend on the tariff arrangement of the water heater replaced and the installation location.

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.
Page 22
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.
Page 23
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 3500.4 so that scalding water temperatures are not delivered to a bathroom, ensuite or other ablution area.
Page 24
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.
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.

HEAT PUMP AND TANK ASSEMBLY Water Connections: Connect the cold water supply and the hot water pipe work to the storage tank. Connect the temperature pressure relief valve and its drain line. Refer to “Connections – Plumbing” on page 39. Water Supply: Turn on the cold water supply and fill the water heater.
CONNECTIONS – PLUMBING All plumbing work must be carried out by a qualified person and in accordance with the Standard AS/NZS 3500.4 and all local codes and regulatory authority requirements. In New Zealand, the installation must conform with Clause G12 of the New Zealand Building Code. CONNECTION SIZES Hot water connection: RP¾/20.
Page 40
CONNECTIONS – PLUMBING TEMPERATURE PRESSURE RELIEF VALVE The temperature pressure relief valve is shipped behind the lower front cover of the water heater. The temperature pressure relief valve must be fitted before the water heater is operated. Before fitting the relief valve, make sure the probe has not been bent.
Page 41
CONNECTIONS – PLUMBING CONDENSATE DRAIN A drain line must be fitted to the heat pump module‟s condensate drain to carry the discharge clear of the heat pump module. The drain line can be extended using 12 mm rigid poly hose or conduit. The pipe work from the condensate drain should be as short as possible, and fall all the way from the water heater with no restrictions.
CONNECTIONS – ELECTRICAL The power supply to the water heater must not be switched on until the water heater is filled with water and a satisfactory megger reading is obtained. MEGGER READING When a megger test is conducted on this water heater, then the following should be noted. Warning: This water heater contains electronic equipment and 500 V insulation tests must only be conducted between active and earth and between neutral and earth.
