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 (70°C for EM50 models). • 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 18, 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.
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. Warning: Children should be supervised to ensure they do not interfere with the water heater.
How Long Will the Water Heater Last The water heater is supported by a manufacturer’s warranty (refer to page 31). There are a number of factors that will affect the length of service the water heater will provide. These include but are not limited to the water chemistry, the water pressure, the water temperature (inlet and outlet) and the water usage pattern. 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.
Major Five (5) Year Service It is recommended a major five (5) year service be conducted on the water heater. Servicing must be performed by a qualified person. Phone Aquamax Service or their nearest Accredited Service Agent. Note: The five (5) year service and routine replacement of any components, such as the anode and relief valve(s), are not included in the Aquamax warranty. A charge will be made for this work. Major five (5) year service actions: 1. Replace pressure temperature relief valve. 2.
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. Danger: Failure to perform this procedure may result in the water heater storage cylinder failing.
The life of the storage cylinder may be extended by arranging a qualified person to periodically inspect the anode and replace if required. If the anode is not replaced during a five (5) year service (refer to “Major Five (5) Year Service” on page 9) then the maximum time after installation when the anode should be replaced for this electric water heater is eight (8) years.
water supply TDS exceeds 600 mg/Litre, the magnesium alloy anode (supplied as standard, cap colour code ‘Black’) should be replaced with an aluminium alloy anode (cap colour code ‘Blue’). For more information refer to “Water Chemistry & Anode Type” on page 12. In locations where TDS approaches 600 mg/Litre, e.g. due to sediment, we strongly recommend fitting an appropriate filter to ensure water entering or in the water heater does not exceed this level at any time i.e. due to sediment build up.
Water Chemistry Levels Affecting Warranty The Aquamax warranty of this water heater will not cover resultant faults on components including the storage cylinder where water stored in the storage cylinder exceeds at any time any of the following levels: Total dissolved solids Total hardness Chloride Magnesium pH Calcium Sodium Iron 600 mg/Litre 200 mg/Litre 300 mg/Litre 10 mg/Litre 9.5 and not less than 6.
Troubleshooting Check the items below before making a service call. If the water heater is within/out of the warranty period you will be charged for attending to any condition or fault that is not related to the manufacture or failure of a part. For warranty terms and conditions (refer to “Warranty” on page 31).
Pressure Temperature Relief Valve Running • Normal Operation It is normal and desirable for the PTR valve to allow a small quantity of water to escape during the heating cycle, however there may be a problem if the valve continuously dribbles more than a bucket full of water in a normal 24 hour cycle. Note: During the first 24 hours after installation the valve may discharge more than a bucket full of water.
• • • • Is one outlet (especially the shower) using more hot water than you think? Refer to “Not Enough Hot Water” on page 14. Is there a leaking hot water pipe, dripping hot water tap, etc? Even a small leak will waste a surprising quantity of hot water and electricity. Replace faulty tap washers and have your plumber rectify any leaks. Has there been an increase in hot water usage? An increase in hot water usage will result in an increase in water heater operation.
water supply in the event that this water heater was to become inoperable for any reason. We recommend you provide advice to the system owner about their needs and building backup redundancy into the hot water supply system. Water Heater Location This water heater is suitable for either outdoor or indoor installation. The water heater should be installed close to the most frequently used outlet and its position chosen with safety and service in mind.
Water Supplies Mains Water Supply Where the mains water supply pressure exceeds that shown in the table below, an approved pressure limiting valve is required and should be fitted after the stop cock and before the non return valve as shown in the “Cold Water Supply Plumbing Arrangement” diagram on page 19.
correctly inserted or aligned, it should be gently pushed back into place before connecting any plumbing fittings. Warning: Plastic liners must be in place for the water heater to function properly. Do not remove or damage liners. Warning: Do not use heat near plastic liners. Heat can be transferred by conduction which may damage liners. Water Inlet & Outlet Connections An approved isolation valve and non return valve must be installed in the supply line to the water heater.
Left & Right Hand Side Water Connections – EM50 Models All Aquamax mains pressure electric water heaters are manufactured with dual inlets and outlets. For EM50 series water heaters, the cold and hot water supply can be connected to either side of the water heater however they must both be connected to the same side of the water heater. Cross connecting will significantly affect the performance of the water heater and is not permitted. Refer to the diagram below for acceptable plumbing connections.
Pressure Temperature Relief Valve (PTR valve) The PTR valve must be fitted before the water heater is operated. Before fitting the PTR valve, make sure the valve probe has not been bent. Seal the valve thread with thread sealing tape (never use hemp) and ensure the tape does protrude past the end of the thread.
If a drain line discharges into a tundish, the drain line from the tundish must be not less than DN20. The drain line from a tundish must meet the same requirements as for a drain line from a relief valve. Warning: As the function of the PTR valve on this water heater is to discharge high temperature water under certain conditions, it is strongly recommended the pipe work downstream of the relief valve be capable of carrying water exceeding 93°C.
Two Temperature Zones Using a Temperature Limiting Device 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.
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.
power supply will provide the maximum financial savings. Discuss the power supply requirements with the householder. Connect the power supply wires directly to the water heaters terminal block and earth tab connection as shown in the wiring diagram provided on the rear of the lower electrical access cover. Ensure there are no excess wire loops inside the front cover.
1. 2. 3. 4. 5. Switch off electrical supply to the water heater. This can be performed at the switchboard or water heaters isolating switch if one is installed. Remove lower access cover. Turn thermostat temperature adjustment dial clockwise to increase temperature setting or anticlockwise to decrease temperature setting. Replace lower access cover. Switch on electrical supply to water heater.
3. Close each hot water tap after all air is purged (when air is purged water will run freely without air bubbles or spluttering). 4. Check all plumbing connections for leaks. 5. Switch on electrical supply to water heater and switch on water heater isolating switch (if one is installed). Explain to the householder, or a responsible officer, the functions and operation of the water heater.
