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 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 12) then the maximum time after installation when the anode should be replaced for this electric water heater is eight (8) years.
The Aquamax warranty will not cover resultant faults to the storage cylinder if this water heater is connected at anytime to a water supply where the TDS content of the water exceeds 600 mg/Litre. 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.

Remove the front access panel and check that a pilot flame is present. If the pilot flame is not burning relight the heater by following the ‘Lighting Instructions’ on page 6.
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 hr cycle. • Continuous dribble Try gently raising the easing lever on the relief valve for a few seconds (refer to ‘Pressure Temperature Relief Valve’ on page 12).
around the base of the water heater. This is quite normal, especially in winter months and the condensate will dry off as the water is heated. The water heater will drip water during the heating cycle. It is possible for several litres a day of condensation to discharge from the unit, especially in cool conditions. This water is not from the mains supply but is condensation from the atmosphere caused by the efficient operation of the water heater.
INSTALLATION Installation Overview This water heater must be installed by a qualified person in accordance with the installation instructions. The installation must comply with the requirements of AS/NZS 3500.4, AS 5601 or AS/NZS 5601.1, all local codes and regulatory authority requirements. Check to ensure the water heater is suitable for the gas type available (refer to the water heaters rating label). All packaging materials must be removed from the water heater prior to its installation.
It is a requirement of AS 5601 and AS/NZS 5601.1 that the water heater is secured to a wall. A wall bracket is supplied with the water heater for this purpose. The top of the unit is to be secured to the wall using the wall bracket and masonry anchor provided (or other suitable fastener). Refer to ‘Wall Bracket Installation’ on page 22. Note: Damage to the storage cylinder caused by incorrect installation is not covered by warranty.
Examples a, b & c from previous table Wall Bracket Installation It is a requirement of AS 5601 and AS/NZS 5601.1 that water heater is secured to a wall. The top of the water heater is to be secured to the wall using the wall bracket and M6.5 masonry anchor provided with the water heater (or other suitable fastener). It is necessary to fix the bracket to the wall after positioning the water heater but prior to making the water and gas connections. To install the wall bracket: 1. Position water heater. 2.
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 when a safe tray must be installed.
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 14 for more information. Also refer to ‘Spring, Dam, Bore & River Water Supplies’ on page 16.
Natural Gas Models: Remove yellow warning label from gas control after connecting gas supply line. Propane Gas Models: A gas regulator is supplied with the water heater and must be installed externally between the gas isolation valve and jacket of the water heater. Refer to gas flow directional arrow on regulator body to ensure it is installed in the correct orientation. The regulator has been factory preset to obtain a burner pressure of approximately 2.7kPa.
Expansion Control Valve In some areas, local regulations may make it mandatory to install an expansion control valve (ECV) in the cold water line to the water heater. Refer to ‘Scaling Water’ on page 16. The ECV must always be installed after the non return valve and be the last valve installed prior to the water heater (refer to the ‘Cold Water Supply Plumbing Arrangement’ diagram on page 25). A copper drain line must be fitted to the ECV (refer to ‘Relief Valve Drain(s)’ on page 26).
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. The outlet of a drain line must be in such a position that flow out of the pipe can be easily seen, but arranged so discharge will not cause injury, damage or nuisance.
cylinder is damaged as a result of installing a Flashing Kit, any resultant faults will not be covered by the Aquamax warranty. 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.
