ABOUT YOUR WATER HEATER

WATER HEATER APPLICATION

This water heater is designed for the purpose of heating potable water. Its use in an application other than this may shorten its life.

MODEL TYPE

The Rheem® Stainless steel heavy-duty Electric water heater model you have chosen can be installed indoors or outdoors and is a 315 litre model, and the 315 litre has three heating units.

Water is stored in a stainless steel cylinder and heated by 3 electric immersion heating units. The temperature is controlled by thermostats. Automatic safety controls are fitted to the water heater to provide safe and efficient operation.

HOW HOT SHOULD THE WATER BE?

The water heater has a minimum temperature setting of 60°C and a maximum recommended thermostat setting of 75°C. Refer to “Temperature Adjustment” on page 11.

To meet the requirements of the National Plumbing Standard, the temperature of the stored water must not be below 60°C. If this water heater is installed as an in-series booster water heater as part of a solar water heating system, to maximise solar contribution, it is recommended that the thermostats are set at 60°C, unless sanitising temperatures are required.

Note: Australian Standard AS 3498 and New Zealand Building Code Clause G12 require that a water heater provide the means to inhibit the growth of Legionella bacteria in potable water. This water heater can satisfy these AS 3498 and Clause G12 requirements provided it is energised and the thermostat setting is 60°C or higher, including when it is used as an in-series booster water heater for a solar water heater.

HOTTER WATER INCREASES THE RISK OF SCALD INJURY

This water heater can deliver hot water at a temperature up to 75°C, depending on its thermostat setting. This temperature is sufficiently hot to cause severe scalding. Water at this temperature may have been plumbed to fixtures where water hotter than 50°C is allowed, such as a kitchen, laundry, and other areas requiring sanitising temperatures.

Check the water temperature before use, such as when entering a shower or filling a bath or basin, to ensure it is suitable for the application and will not cause scald injury.

We recommend, and it may be required by regulation, that an approved temperature limiting device be fitted into the hot water pipe work to bathrooms, en-suites, public amenities, or other ablution areas when this water heater is installed. This will keep the water temperature below the maximum permitted by the Plumbing Code of Australia and the New Zealand Building Code Clause G12 in these areas. The risk of scald injury will be reduced while allowing hotter water to the kitchen, laundry, and other areas requiring sanitising temperatures.

THERMOSTATS

The thermostats automatically control the electricity supply to the heating unit, so a constant temperature is maintained. The thermostats and their protective over-temperature cut-out are mounted inside the front cover of the water heater. There is no need to switch the water heater off when it is not in use. The thermostats are fully automatic, and power is only used when heating is required.

TEMPERATURE ADJUSTMENT

The water heater features tradesperson-adjustable thermostats. They require a licensed electrical worker to make any temperature adjustments. We advise that the thermostats be adjusted to the lowest temperature setting that meets your needs, especially if there are young children or elderly people in the premises. Refer to “Hotter Water Increases the Risk of Scald Injury” on page 10.

PRECAUTIONS

Under certain installation conditions where property damage can occur in the event of the water heater leaking, AS/NZS 3500.4 requires the water heater to 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. In New Zealand, the safe tray must also meet the requirements of Clause G12 of the New Zealand Building Code. AS/NZS 3500.4 and the NZBC also have particular requirements when a safe tray must be installed. Alternatively, where additional leak protection is required for installations not defined by AS/NZS 3500.4, a suitable bund may be constructed to surround the water heater in lieu of using a safe tray.

If this water heater is to be used where an uninterrupted hot water supply is necessary for your application or business, you should ensure that you have back-up redundancy within the hot water system design. This should ensure the continuity of the hot water supply if this water heater were to become inoperable for any reason. We recommend you seek advice from your plumber or specifier about your needs and building backup redundancy into your hot water supply system.

TO TURN OFF THE WATER HEATER

If it is necessary to turn off the water heater:

• Switch off the electrical supply at the water heater isolating switch(s) on the switchboard or at the isolating switch(s) at the water heater(s) (if installed).
• Close the cold water isolation valve on the cold water line to the water heater(s) to shut down the entire system, or;
• Close the isolation valves on the cold and hot water branches to shut down an individual water heater in a bank.

TO TURN ON THE WATER HEATER

• Open the isolation valves fully on the cold and hot water branches to the water heater(s) installed in a bank.
• Open the cold water isolation valve on the cold water line to the water heater(s). Air will be forced out of the taps.
• Switch on the electrical supply at the water heater isolating switch(s) on the switchboard and at the isolating switch(s) at the water heater(s) (if installed).

VICTORIAN CUSTOMERS

Notice to Victorian Customers from the Victorian Building Authority. This water heater must be installed by a licensed person as required by the Victorian Building Act 1993.

Only a licensed person will give you a Compliance Certificate, showing that the work complies with all the relevant Standards. Only a licensed person will have insurance protecting their workmanship for 6 years. Make sure you use a licensed person to install this water heater and ask for your Compliance Certificate.

DOES THE WATER CHEMISTRY AFFECT THE WATER HEATER?

The water heater is suitable for most public water supplies; however, some water chemistries may have detrimental effects on the water heater, its components, and fittings. Refer to “Water Supplies” on page 13. If you are in a known harsh water area or you are not sure of your water chemistry, have your water checked against the conditions described on pages 13 to 16.

HOW LONG WILL THE WATER HEATER LAST?

The water heater is supported by a manufacturer’s warranty (refer to page 4). 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. Refer to “Precautions” on page 11.

MAINTENANCE REQUIREMENTS

MINOR MAINTENANCE EVERY SIX MONTHS

It is recommended that minor maintenance be performed every six (6) months. Minor maintenance can be performed by a responsible officer.

The minor maintenance includes:

• Operate the easing lever on the temperature pressure relief valve. The lever must be raised and lowered gently. Refer to “Relief Valves” on page 8.
   Warning: Water discharged from the temperature pressure relief valve drain line will be hot. Exercise care to avoid any splashing of water by standing clear of the drain line’s point of discharge when operating the valve’s easing lever.
• Operate the easing lever on the expansion control valve (if fitted). The lever must be raised and lowered gently. Refer to “Relief Valves” on page 8.
• Check that the drain line from the safe tray (if one is installed) is not blocked.

MAJOR SERVICE EVERY FIVE YEARS

It is recommended that a major service be conducted on the water heater every five (5) years.

 Warning: Servicing of a water heater must only be carried out by qualified personnel. Phone Rheem Service or their nearest Accredited Service Agent / Centre.

Note: The major service and routine replacement of any components, such as the relief valve(s), are not included in the Rheem warranty. A charge will be made for this work. Only genuine replacement parts should be used on this water heater.

The major service includes the following actions:

• Replace the temperature pressure relief valve.
• Inspect and flush the expansion control valve (if fitted). If required, replace the valve.
• Check the electric heating units for excessive calcium build-up or corrosion and replace if necessary.
• Drain and flush the water heater if required.
  In commercial applications where large volumes of hot water are used, sediment may build up on the bottom of the cylinder. In extreme cases, particularly in areas of high water sediment, draining and flushing out may be necessary.
• Visually check the unit for any potential problems.
• Inspect all connections.
• Check that the drain line from the safe tray (if one is installed) is not blocked.

Note: The water heater may need to be drained during this service. After the completion of the service, the water heater will take some time to reheat the water. Depending upon the power supply connection, hot water may not be available until the next day.

WATER SUPPLIES

This water heater must be installed with this advice to be covered by the Rheem warranty.

This water heater is manufactured to suit the water conditions of most public reticulated water supplies. However, there are some known water chemistries that can have detrimental effects on the water heater and its operation and/or life expectancy. A list of postcodes is available on the Rheem website (www.rheem.com.au) indicating known areas where the stainless steel cylinder is not covered by the Rheem warranty due to the water chemistry of the area. The list is not necessarily exhaustive, and there may be areas outside of these postcodes where the stainless steel cylinder is not covered by the Rheem warranty due to the water chemistry of the area.

If you are unsure of your water chemistry, you may be able to obtain information from your local water supply authority. This water heater should only be connected to a water supply that complies with these guidelines, which takes precedence over the list of postcodes, for the Rheem warranty to apply. It is recommended to install a suitable filter on the cold water supply line to the water heater if the water supply contains or has a future risk of containing suspended solids. The Rheem warranty will not cover resultant faults on components, including the stainless steel cylinder, due to the effects of sludge and/or sediment settling in the water heater.

CHANGE OF WATER SUPPLY

The changing or alternating from one water supply to another can have a detrimental effect on the operation and/or life expectancy of a water heater cylinder, a temperature-pressure relief valve, and a heating unit.

Where there is a changeover from one water supply to another, e.g. a rainwater tank supply, bore water supply, desalinated water supply, public reticulated water supply or water brought in from another supply, then water chemistry information should be sought from the supplier or it should be tested to ensure the water supply meets the requirements given in these guidelines for the Rheem warranty to apply.

Note: Some water analysis reports may state the conductivity of the water rather than the level of total dissolved solids. Conductivity, measured in microsiemens per centimetre (μS / cm), is directly proportional to the TDS content of the water. TDS, in mg / L, is approximately 70% of the conductivity in μS / cm.

CHLORIDE AND PH

In a high chloride water supply, the water can corrode stainless steel parts and cause them to fail.

Where the chloride level exceeds 250 mg/L /, the Rheem warranty does not apply to a stainless steel cylinder. pH is a measure of whether the water is alkaline or acidic. In an acidic or very alkaline water supply, the water can attack stainless steel parts and cause them to fail.

Where the pH is less than 6.0 or greater than 9.5, the Rheem warranty does not apply to a stainless steel cylinder. Water with a pH less than 6.0 may be treated to raise the pH.

The water supply from a rainwater tank in a metropolitan area is likely to be corrosive due to the dissolution of atmospheric contaminants. This may result in a pH of less than 6.0. It is recommended that an analysis of the water from a rainwater tank be conducted before connecting this type of water supply to a water heater with a stainless steel cylinder.

Refer to the pH and Chloride chart on page 15.

SATURATION INDEX

The saturation index is used as a measure of the water’s corrosive or scaling properties. The saturation index figures stated are calculated using a water temperature of 80°C.

In a corrosive water supply, the water can attack copper parts and cause them to fail. Where the saturation index is less than 1.0, the water is very corrosive, and the Rheem warranty does not apply to a copper sheathed heating unit.

A corrosion-resistant heating unit must be used for the Rheem warranty to apply to the heating unit. This water heater is supplied fitted with a corrosion-resistant heating unit. In a scaling water supply, calcium carbonate is deposited out of the water onto any hot metallic surface. Where the saturation index exceeds +0.40, the water is very scaling. An expansion control valve must be fitted on the cold water line after the non-return valve to protect the Rheem warranty to apply to the temperature pressure relief valve and water heater cylinder.

Where the saturation index exceeds +0.80, the Rheem warranty does not apply to a stainless steel cylinder or a standard watts density heating unit. A low-watt density heating unit must be used for the Rheem warranty to apply to the heating unit.

Water that is scaling may be treated with a water softening device to reduce the saturation index of the water. Contact Rheem Service or their nearest Accredited Service Agent if a replacement heating unit is required. Refer to the Saturation Index chart on page 16. Refer to the cold water connection detail on page 35 for the position of the expansion control valve.

TOTAL DISSOLVED SOLIDS

The stainless steel 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 600 mg / L.

Note: Some water analysis reports may state the conductivity of the water rather than the level of total dissolved solids. Conductivity, measured in microsiemens per centimetre (μS / cm), is directly proportional to the TDS content of the water. TDS, in mg / L, is approximately 70% of the conductivity in μS / cm.

SUMMARY OF WATER CHEMISTRY ADVICE AFFECTING WARRANTY

The water heater and its components are not suitable for certain water chemistries. Those chemistries are listed below. If the water heater is connected at any time to a water supply with the following water chemistry, the Rheem warranty will not cover any resultant faults on the components listed below:

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 the 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” or “WATER HEATER” at the switchboard and the isolating switch (if one is installed) near the water heater, and ensure they are turned on.
  Note: Check the electricity supply to which the water heater is connected. If on a time-controlled electricity supply, remember heating hours are restricted.
  Check the fuse or circuit breaker marked “HOT WATER” or “WATER HEATER” at the switchboard.
• Are you using more hot water than you think?
  Are outlets (especially the showers) using more hot water than you think? Very often, it is not realised the amount of hot water used, particularly when showering.
  Carefully review the hot water usage. Have your plumber fit a flow control valve to each shower outlet to reduce water usage.
• Relief valve running
  Is the relief valve discharging too much water?
  Refer to “Temperature Pressure Relief Valve or Expansion Control Valve Running” on page 18.
• Thermostat setting
  Ensure the thermostat setting is appropriate. You may choose to have a licensed electrical worker adjust the thermostats upwards to gain additional hot water capacity.
   Warning: Hotter water increases the risk of scald injury.
• Water heater size
  Do you have the correct size water heater for your requirements?
  The sizing guide in the Rheem sales literature and on the Rheem website (www.rheem.com.au) suggests average sizes that may be needed.

TEMPERATURE PRESSURE RELIEF VALVE OR EXPANSION CONTROL VALVE RUNNING

• Normal Operation
  It is normal and desirable that the temperature pressure relief valve or expansion control valve (if fitted) allows a quantity of water to escape during the heating cycle. This quantity should be equal to approximately 1/50 of the hot water used, as water expands by this volume when heated. However, if it discharges more than a bucket full of water in 24 hours, there may be another problem.
  The expansion control valve (if fitted) will discharge water instead of the temperature pressure relief valve, as it has a lower pressure rating. A benefit is that energy is conserved as the discharged water is cooler. This valve is installed in the cold water line to the water heater (refer to the cold water connection diagram on page 25).
• Continuous dribble
  Try gently raising the easing lever on the relief valve for a few seconds (refer to “Relief Valves” on page 8). This may dislodge a small particle of foreign matter and clear the fault. Release the lever gently.
• Steady flows for long periods (often at night)
  This may indicate themains water pressure sometimes rises above the designed pressure of the water heater. Ask your installing plumber to fit a pressure-limiting valve.
   Warning: Never replace the relief valve with one of a higher pressure rating.
• Heavy flows of hot water from the temperature pressure relief valve until the water heater is cold, then stops until the water reheats.
  The water heater must be switched off at the switchboard. Phone Rheem Service or their nearest Accredited Service Agent / Centre to arrange for inspection.

HIGHER THAN EXPECTED ELECTRICITY BILLS

Should you, at any time, feel your electricity bill is higher than expected, we suggest you check the following points:

• Is the relief valve running excessively?
  Refer to “Temperature Pressure Relief Valve or Expansion Control Valve Running” on page 18.
  Are outlets (especially the showers) using more hot water than you think?
  Refer to “Not Enough Hot Water” on page 17.
• 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 leaking pipe work.
• Has there been an increase in hot water usage?
  An increase in hot water usage will increase water heater operation.
• Has your water heating tariff rate been increased by your electricity retailer since your previous bill?
• The electricity tariff to which your water heater is connected will determine the overall operating cost of the system.
  It is important that you are aware of this tariff, i.e., continuous or time-controlled supply.

IF YOU HAVE CHECKED ALL THE FOREGOING AND STILL BELIEVE YOU NEED ASSISTANCE, PHONE RHEEM SERVICE OR THEIR NEAREST ACCREDITED SERVICE AGENT / CENTRE.
