Page 3: Applications
25mJ/m UV dose in good quality clear water found in most metropolitan water supplies. A free water test can be conducted if in doubt as to the UV transmission. Please contact Rheem for further assistance. Rheem UV lamps are low pressure, high efficiency lamps contained within a protective quartz thimble which sit inside a high grade electro-polished reactor chamber allowing maximum water exposure to UV light within the chamber for optimal pathogen destruction.
Page 4: General Safety Instructions
Do not use, connect or switch on the UV lamp outside the UV disinfection reactor chamber. Ensure the UV disinfection unit is electrically isolated before: Carrying out repairs. Rheem recommends that the maintenance be carried out only by qualified personnel.
Page 5 The Rheem warranty may not cover faults if safety devices are tampered with or if the installation is not in accordance with these instructions. PRECAUTIONS Where damage to property can occur in the event of the water heater leaking, the UV disinfection system must be installed over safe tray.
Page 6 In an acidic water supply, the water can attack stainless steel parts and cause them to fail. Where the pH is less than 6.0 the Rheem warranty does not apply to the stainless steel UV chamber in the ultra violet disinfection system.
Page 7 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 expectation of the UV system. 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 warranty to...

Page 9: Installation Checklist
INSTALLATION CHECKLIST The following items must be checked prior to installation A maximum operating pressure of 1000kPa (10bar) must not be exceeded. A maximum ambient temperature of 45°C. (To be installed under a shelter) The maximum water temperature should not exceed 55°C (De-energise UV system during any heat disinfection process where the temperature exceeds 55°C).
Page 10 INSTALLING THE REACTOR The reactor chamber (Picture 1) is to be fixed by means of the mounting brackets, either on the wall or on a mounting frame. Both disinfection chamber types can be mounted vertically or horizontally; the water should flow in from the bottom and out through the top to prevent airlocks.
Page 11 Breakage due to mishandling is not covered by the Rheem warranty. Unscrew the sealing nut from the top of the reactor; ensure that the “O” ring is also removed.
Page 12 Picture 4 During this next step the “O” ring should slip over the open end of the quartz thimble. Check this by looking through the sealing nut to ensure the “O” ring does not become pinched, as this will damage the quartz. Screw the sealing nut with the “O”...
Page 13 Note: When you reach this stage, the nut only needs to be turned ½ to ¾ of a turn to compress the “O” ring sufficiently and form a seal. You may check the “O” ring has been compressed well onto the quartz thimble by looking down through the sealing nut. Ideally a good compression will see 2-3mm of “O”...
Page 14 Picture 9 UILDING MANAGEMENT SYSTEMS (BMS) The Rheem UV disinfection power supply can output up to a 240V/2A voltage free signal to a BMS to indicate lamp run and/or fail status. Connecting between common (C) & Normal Open (NO) indicates RUN status.
Page 15: Operation
OPERATION Once the UV reactor and power supply have been correctly installed and tested for leakage, operation is as follows; Ensure any valve is open to allow water flow through the UV disinfection unit. Insert the power lead into the mains power source and switch on the power. The UV lamp will ignite and come on, however it will take between 2 and 5 minutes for the lamp to reach full output.

Rheem Service provides a comprehensive maintenance program structured to meet the most stringent requirements to maintain the product at peak performance and monitor for the presence of Legionella.
Page 17: Service Procedures
Breakage due to mishandling is not currently covered by the Rheem warranty. During this step take care to hold onto the quartz thimble, as it may come out when you remove the sealing nut.
Page 18 Picture 11 If the quartz thimble is due for replacement carefully unwrap the new quartz from the packaging. If the quartz is due for a clean, wipe it down with methylated spirits or washed down with water. It may be necessary to scrape off the remnants of the old “O” ring with a sharp knife. Repeat this step until the quartz is clean.
Page 19 Picture 12 Reinstall the UV lamp (see installation section) POWER SUPPLY UNITS The servicing of the power supply box should only be carried out by qualified service technicians. The power supply box has a 5amp fuse which may need replacing. If the fuse has blown then the cause must be determined before proceeding.
