ABOUT YOUR BOILING WATER UNIT

INTRODUCTION

Thank you for choosing our Rheem Boiling Water Unit. Please take a few minutes to read this booklet because it contains important information about the correct installation and operation of your boiling water unit. The Rheem Boiling Water Unit supplies boiling water. It is made from high quality copper and is designed to be installed indoors. The Rheem Boiling Water Unit is supplied with all the required safety controls for installation (not including the isolation valve prior to the boiling water unit).

WARNING:

This boiling water unit is only intended to be operated by persons who have the experience or the knowledge and the capabilities to do so. This boiling water unit is not intended to be operated by persons with reduced physical, sensory or mental capabilities i.e. the infirm, or by children. Children should be supervised to ensure they do not interfere with the boiling water unit. This boiling water unit uses 230-240 V AC electrical power for operation of the control systems and the electrically operated components. The removal of the access cover(s) will expose 230-240 V wiring. They must only be removed by a qualified person.

SAFETY

This boiling water unit is supplied with an over temperature cut-out on the boiling element to prevent element burn out in the event of control failure. If the electrical supply cord to the boiling water unit is damaged, it must be replaced by a qualified competent person in order to avoid becoming a hazard. In Australia phone Rheem Service on 131 031, in New Zealand phone your nearest Rheem Service Centre on 0800 657 335 for an inspection. For extra electrical protection against power surges and spikes it is recommended that the user install a surge protector prior to the boiling water unit.

WARNING:

The Rheem warranty may not cover faults if any of the installed safety devices

are tampered with.

TO TURN OFF THE BOILING WATER UNIT

The boiling water units are supplied with a programmable timer (see page 6), Rheem recommend the timer function be used to conserve energy.

If it is necessary to turn off the boiling water unit:

• Switch off the electrical supply at the isolating switch to the boiling water unit.

• Close the cold water isolation valve at the inlet to the boiling water unit.

TO TURN ON THE BOILING WATER UNIT

• Open the cold water isolation valve fully on the cold water line to the boiling water unit.

• Switch on the electrical supply at the isolating switch to the boiling water unit.

Note:

The boiling water unit may not appear to turn on immediately when it is first switched on as the electronic controller will automatically check the system prior to allowing water into the boiling water unit (this could be up to 10 seconds).

On initial start up after installation, this boiling water unit automatically runs through a set-up cycle to detect the boiling point of water. During this cycle steam may discharge from the vent pipe for a short time. This set-up cycle will take up to 18-30 minutes depending on unit, and when completed (boiling point detected) the unit will commence incremental filling. It is important NOT to operate the tap during the set-up cycle because it may affect the operating temperature of the unit.

IS THIS BOILING WATER UNIT INSTALLED CORRECTLY?

Installation requirements are shown under Installation (on page 18). The boiling water unit must be installed:

• by a qualified person, and

• in accordance with the installation instructions, and

• in compliance with Standards AS/NZS 3500.4, AS/NZS 3000 and all local

codes and regulatory authority requirements.

In New Zealand, the installation must also conform to Clause G12 of the New Zealand Building Code

DOES THE WATER QUALITY AFFECT THE BOILING WATER UNIT?

The boiling water unit is suitable for most public water supplies, however some water qualities may have detrimental effects on the boiling water unit, its components and fittings. If you are in a known harsh water area you must first read Water Supplies (on page 16). If you are not sure, have your water quality checked against the conditions described on page 16.

HOW LONG WILL THE BOILING WATER UNIT LAST?

There are a number of factors that will affect the length of service the boiling water unit will provide. These include but are not limited to the water quality, the water usage pattern etc. Refer to “Precautions” below However, your boiling water unit is supported by a comprehensive Rheem warranty (refer “Rheem Warranty” on page

28).

PRECAUTIONS

The boiling water unit must be maintained in accordance with the Owner’s Guide and Installation Instructions.

If this boiling water unit is to be used where an uninterrupted boiling water supply is necessary for your application or business you should ensure that you have back up redundancy within the building. This should ensure the continuity of boiling water supply in the event that this boiling water unit were to become inoperable for any reason. We recommend you seek advice from your plumber or specifier about your needs and building back up redundancy.

HOW YOUR BOILING WATER UNIT WORKS

The boiling water unit is designed to operate using mains water pressure by connecting directly to the mains water supply. If the mains supply pressure in your area exceeds 1000kPa a secondary pressure limiting valve must be fitted. The supply pressure should be greater than 50 kPa (3-10Litre), 75kPa (15-25L) or 100kPa (40L) for the Rheem Boiling Water Unit operating to its optimum performance.

BOILING WATER

The Rheem Boiling Water Unit is electronically controlled to obtain the maximum performance, and incorporates further safety devices to prevent over temperature and over filling.

ELECTRONIC CONTROLLER & TIMER

Your Rheem boiling water unit incorporates smart heating software and an electronic timer to obtain the best efficiency for the energy used. The electronic timer allows the user to program when the unit is on or off and when the sleep mode activates to save energy. Also the operator has the availability to indicate and diagnose any system faults that occur without the need to unnecessarily call for a service technician. (Refer “Setting the Timer” on page 7)
