ABOUT YOUR WATER HEATER Product 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 ® Aquamax electric storage water heaters are available with either a single heating unit or with twin heating units (refer to “Single Element Model” and “Twin Element Model” on page 4).
Single Element Model This type of water heater has one heating unit with its own thermostat. The heating unit is at the base of the water heater and the unit can be connected to a continuous or off-peak electricity supply. The thermostat is adjustable between 60 ~ 75°C with a factory setting of 65°C. • Continuous electricity supply This type of connection is suited to where the storage capacity is less than the normal daily usage.
Mains Pressure Operation This 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 in “Mains Water Supply” on page 16, a pressure limiting valve must be fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
To minimise scalding, especially for those people in high scald risk categories i.e. young children, people with potentially incapacitating medical conditions, elderly people etc, this water heater must be installed in accordance with AS/NZS 3500.4.
the front cover(s) will expose 240V wiring. Access covers must only be removed by an electrician or qualified person. Warning: Thermostat temperature adjustment must only be performed by an electrician or qualified person. Warning: Children should be supervised to ensure they do not interfere with the water heater. Other Important Information Going Away? If you plan to be away from home for one or two nights, we suggest you leave the water heater switched on.
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. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4 and all local codes and regulatory authority requirements. The water heater must be maintained in accordance with the Owner’s Guide and Installation Instructions. Refer to “Periodic Maintenance” below.
3. Visually check the water heater for any potential problems. 4. Inspect all plumbing and electrical connections. Note: The water heater will need to be drained during this service and will take some time to reheat the water after servicing has been completed. Depending upon the power supply connection, hot water may not be available until the next day. Major Five (5) Year Service It is recommended a major five (5) year service be conducted on the water heater.
Operate the easing lever on the PTR valve once every six months. It is very important you raise and lower the lever gently. Warning: Exercise care when operating easing lever as water discharged from the water heater may be of a very high temperature. Warning: Exercise care to avoid any splashing of water, as water discharged from the drain line will be hot. Stand clear of the drain line’s point of discharge when operating the valve’s lever.
Water Chemistry This water heater must be installed in accordance with this advice to be covered by the Aquamax 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.
Scaling Water Scaling water is water that contains levels of calcium carbonate (total hardness in excess of 200 mg/Litre at any time when the water heater is operating). Scaling water can block and prevent the pressure temperature relief valve from operating resulting in damage to the water heater storage cylinder and water heater components. An ECV is mandatory in SA & WA and must be fitted in ALL areas with scaling water to assist in preventing blockage of the pressure and temperature relief valve.
Note: Check the electricity supply to which the water heater is connected. If the water heater is connected to an Off-Peak or time controlled electricity supply, heating hours will be restricted (refer to “Off-Peak Electricity Supply” on page 4). • Twin element water heaters A twin element non simultaneous model must have power available to the top heating unit circuit at all times for the water heater to operate as designed. Have your electrician check to ensure this is the case.
• Steady flows for long period (often at night) This may indicate the mains water pressure sometimes rises above the designed pressure of the water heater. Ask your installing plumber to fit a pressure limiting valve. Warning: Never use reconditioned relief valves and never replace the relief valve with one of a higher pressure rating. • 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.
The electricity tariff to which your water heater is connected will determine the overall operating cost of the system. It is important you are aware of this tariff, i.e. Off-Peak (overnight) or time controlled supply, Extended Off-Peak (overnight and day) or Extended time controlled supply, Domestic/Continuous. Contact your energy supplier for information relating to your water heating tariff rate.
able to read the information on the rating plate. If adequate room is unavailable, the water heater must be disconnected, drained and removed to enable servicing. For outdoor installation, the water heater shall be installed freestanding on a level and stable concrete base 50mm thick. For indoor installation or where property damage could occur, an overflow tray and drain must be fitted in accordance with AS/NZS 3500.4.
including the water heater. Care must be taken to avoid air locks. The cold water supply line to the water heater must be adequately sized and fitted with an approved full flow gate valve or ball valve and non return valve. Water Supply Chemistry Bad water can have a detrimental effect on water heater operation, components and life expectancy and may affect warranty. Refer to “Water Chemistry” on page 11 for more information. Also refer to “Spring, Dam, Bore & River Water Supplies” on page 12.
Left & Right Hand Side Cold Water Connections – E80 ~ E315 Models All Aquamax mains pressure electric water heaters are manufactured with dual inlets. For E80 ~ E315 models, the cold supply can be connected to either side of the water heater. A brass plug is supplied with the water heater to plug off the unused cold water supply fitting. When installing the brass plug, apply thread sealing tape or an approved thread sealant to plug thread before installation.
maximum length of 9 metres for a drain line is reduced by 1 metre for each additional bend required of greater than 45°, up to a maximum of three additional bends. Where the distance to the point of final discharge exceeds this length, the drain line can discharge into a tundish. Subject to local regulatory authority approval, the drain lines from the ECV and PTR valve from an individual water heater may be interconnected.
Pipe Work Insulation To reduce heat loss, 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. Saddling Pipe Work To prevent damage to the storage cylinder when attaching pipe clips or saddles to the water heater jacket, we recommend the use of self drilling screws with a maximum length of 13mm.
Circulated Hot Water Flow & Return Systems For circulated hot water flow and return systems, a temperature limiting device can only be installed on a dead leg which branches off the circulated hot water flow and return pipe. Warning: Installing a temperature limiting device in the circulated flow and return pipe work, or circulating tempered water from a temperature limiting device may cause water to be delivered to ablution areas at a temperature exceeding the requirements of AS/NZS 3500.4.

Electrical & Electrical Connections Warning: 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. All electrical work must be carried out by a qualified person in accordance with AS/NZS 3000, AS/NZS 3008 and any local authority requirements.
Thermostat Adjustment Warning: The thermostat and its protective over temperature cut out are mounted inside the front cover(s) of the water heater. The removal of the front cover(s) will expose 240V wiring. Access covers must only be removed by an electrician or qualified person. Warning: Thermostat temperature adjustment must only be performed by an electrician or qualified person.
Commissioning After installation and before commissioning the water heater the following pre commissioning procedure must be performed: 1. Check to ensure that all wiring links and electrical connections are secure and tight. 2. To ensure the over temperature and energy cut out is set, press and release the black reset button on the thermostat(s) (refer to diagram in “Thermostat Adjustment” on page 24). 3. Perform a megger (insulation) test on the water heater.
To Turn OFF the Water Heater Sometimes it is necessary to turn off the water heater after installation and commissioning. This may be required on a building site or where the premises are vacant. To turn off the water heater: 1. Switch off electrical supply to the water heater. This can be performed at the switchboard or water heaters isolating switch if one is installed. 2. Close cold water isolation valve on cold water line to water heater.
