Safety Precautions
!
Warning

•CAUTION - To prevent possible fire or electrical shock, use only replacement lamp
specified by the manufacturer.
•A bonding lug is provided on the external surface. To reduce the risk of electric
shock, connect the local common bonding grid in the area of the swimming pool,
spa, or hot tub to these terminals with an insulated or bare copper conductor not
smaller than 8 AWG US / 6 AWG Canada.
•Replace damaged cords immediately.
•Lamps and quartz sleeves are made of glass and are extremely delicate. Care should
be taken when handling or replacing these components. Wear cotton gloves when
handling lamps or sleeves. Hold bulbs by the ends only. Never touch the glass with
bare hands. Wipe any fingerprints from lamps and sleeves with alcohol.
•CAUTION - this device is for swimming pool use only. Do not use this device for
potable (drinking) water sanitization.
•DANGER - ULTRAVIOLET RADIATION. Disconnect Power Before Replacing Lamp .
•This device contains an ultraviolet lamp that can cause discomfort, irritation and
damage to the eyes if viewing occurs while device is in operation. Prolonged
exposure to the eyes can cause serious injury to the eyes, including blindness. DO
NOT VIEW UV LAMP WHILE THE DEVICE IS IN OPERATION.

HydroRite: How It Works
The Hayward HydroRite contains a high intensity electrically operated Ultraviolet (UV)
lamp which is located inside the unit’s wet chamber. The UV lamp emits light at two
separate wavelengths within the UV spectrum; 254 nm and 185 nm.
The 254 nm wavelength is called the “germicidal” wavelength. This wavelength is
capable of inactivating a wide array of microorganisms such as bacteria, viruses,
protozoa (e.g. Cryptosporidium and Giardia), algae spores and other single vesseled
waterborne microbes. The 254 nm UV light alters the DNA and RNA of the
microorganisms rendering them incapable of infection.
The 185 nm wavelength, on the other hand, is called the “ozone generating”
wavelength and is responsible for converting oxygen, contained in the quartz sleeve
area, into ozone. The ozone created is introduced into the water stream using a
venturi. Ozone, a strong oxidizer and bactericide in its own right, works together with
the UV to oxidize bather waste and inactivate microorganisms utilizing a process
known as “advanced-oxidation”.
