Key to symbols and safety instructions 1 Key to symbols and safety instructions 1.1 Key to symbols Warnings Warnings in this document are identified by a warning triangle printed against a grey background. Keywords at the start of a warning indicate the type and seriousness of the ensuing risk if measures to prevent the risk are not taken. The following keywords are defined and can be used in this document: • NOTICE indicates a situation that could result in damage to property or equipment.
Key to symbols and safety instructions ▶ Removal of access covers will expose 240V wiring. Do not remove the terminal box cover unless the power supply has been effectively disconnected by an authorised person. ▶ Do not operate this water heater with terminal box cover removed or loose. ▶ This water heater is not intended to be operated or adjusted by young children or infirm persons. Young children must be supervised to ensure they do not interfere with the water heater.
Key to symbols and safety instructions WARNING: Hot water can cause scalds. Children, disabled and the elderly are at greatest risk. Scalds from hot water can result in severe injuries to young children. Feel water temperature before bathing or showering. Scalds can occur when children are exposed directly to hot water when they are placed into a bath that is too hot.
Key to symbols and safety instructions WARNING: Do not operate this water heater unless all safety devices are fitted and functioning normally. CAUTION: Failure to operate the relief valve easing gear at least once every six months may result in product fault. It is important that the easing gear on the valve be raised and lowered very gently. Failure to do so may result in the water heater cylinder failing, or faulting under certain circumstances.

Appliance details Fig. 3 Appliance overview - New Zealand 3.2 Features and general information Your storage electric water heater consists of a vitreous enamel lined steel cylinder, an internally adjustable thermostat, a pre-painted zinc-coated steel shell or exterior, an immersion type element, a sacrificial anode, and a PTR safety valve. Water is stored within the steel inner tank and is heated to the thermostat set temperature by the element.
Appliance details the householder on how to dissipate the gas safely. This process is explained under “Hydrogen warning” on page 4. Any change of anode must be carried out by an authorised service person. Corrosive Water Water deemed to be corrosive can attack copper parts causing them to fail. When the water supply Saturation Index (check with your local water supplier for additional information) is less than -1.0, water is deemed corrosive and a corrosion resistant heating element should be used.

Installation instructions WARNING: Electric water heaters are heavy and bulky. Australian States and Territories have a Principal Occupational Health and Safety (OH&S) Act which contains requirements relating to the handling of large, bulky, or awkward items.
Installation instructions NOTICE: Material damage! ▶ Install a filter at the water inlet in areas where the water contains particles or sediments ▶ Where water pipes are attached to the tank exterior, screws of no longer than 25mm should be used. Any damage to the tank will not be covered by warranty WARNING: Flush out pipes before connecting this water heater to ensure no foreign matter can block the valve seat, and use line strainers where required by local authorities.
Electrical connection NOTICE: This drain pipe must fall continuously, shall be left open to the atmosphere, and shall be in a frost free environment WARNING: Relief valve easing gear should be checked and operated AT LEAST ONCE EVERY SIX MONTHS. If water does not discharge freely when the lever is operated, the valve should be checked by an authorised agent. WARNING: The relief valve and relief valve drain pipe must not be sealed or blocked.
Seismic strapping 7 Seismic strapping Fig. 7 [A] Extra centre strap for water heaters exceeding 200L [B] Storage water heaters to be restrained with 25x1 galvanized steel straps tensioned when fixed in place. Straps to be fixed to wall framing with: - 1 No. 8 coach screw with 30x2 thick washer, or -2 No. 20x2.5 thick washers. Screws to penetrate timber framing a minimum of 50. [C] 50x50 vertical blocking full height of water heater, fixed to wall framing with 1 No. 100x3.
Commissioning 8 Commissioning 8.1 Before commissioning 9 DANGER: Electric shock! ▶ Isolate the appliance from the power supply using the circuit breaker isolation switch or another protection device before carrying out any work on electrical parts NOTICE: Do not start the appliance without water! ▶ Only operate the appliance once it has been filled with potable water. ▶ Ensure the cylinder is filled with water ▶ Check all connections for water tightness ▶ Check the electrical connection. 8.
Maintenance and repair 9.2.4 Continuous discharge from ECV & PTR valves Discharges of more than 15 litres of water in 24 hours indicates that the valve may not be functioning correctly. This may be remedied by gently easing the valve lever for a few seconds as described under Routine Service to dislodge any foreign matter. CAUTION: Continual flow may also indicate high water pressure which will require a pressure limiting valve to be fitted by an authorised person. 9.
Water quality ▶ Reconnect power to the water heater. CAUTION: Turn off the power supply to the water heater before draining water. If you intend on being away from your house for only a few days, we suggest you leave the water heater switched on. 10.3.1 Draining the water heater ▶ Isolate the electrical supply at the main switchboard via the circuit breaker switch or isolating switch, and then remove the fuse. ▶ Isolate the cold water supply to the appliance.
Environmental protection/Recycling “Safety”. The change of anode must be done by a plumber or authorised service person. Corrosive Water Water deemed to be corrosive can attack parts causing them to fail. When the water supply Saturation Index (check with your local water supplier for additional information) is less than 1.0, water is deemed corrosive and a corrosion resistant heating element should be used. The effect of scaling water is the build up of calcium carbonate onto hot metallic surfaces.
