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”.

Flow & Interlock Sensors (interchangeable)

HydroRite: LED Indicators
Flow/Over Temperature/Interlock LED
The HydroRite will shut down due to the following
conditions:
•Flow - the LED indicates a no or low flow condition.
•Over Temperature - The HyroRite has a temperature
sensor that will shut down operation to protect itself if
high temperatures are sensed. This can be caused by
high ambient temps & direct sunshine.
•Interlock - The LED indicates the vessel cap has not been
installed properly OR the interlock connection is not
properly made.
15
Power On LED
This green LED will be on under normal operation. Even
when the pool pump is not running and HydroRite shuts off
its lamp, the Power On LED will be lit.
Lamp/Ballast LED
This red LED indicator implies an issue with the lamp or
ballast, or a problem with the connection from the ballast
cable to the lamp. Note that the lamp has a defined life and
will eventually need to be replaced.

Maintenance

1. Unplug the device from the power outlet
(Fig 8 & 9).
2. Shut off the circulation pump and make
sure there is no pressure in the system.
Then close the inlet and outlet valves on
either side of HydroRite.
3. Drain the unit by unscrewing the
threaded plug from the base of the
vessel (Fig. 9 & 10). NOTE: If the Acid Wash
system is plumbed, remove the hose to the
shut-off valve from the base of the vessel. You
can then open the valve to release the pool
water.
4. Removing the Electrical Enclosure Cover
by unscrewing the four screws (Fig. 12 &
13).
5. Remove the power clips from the
Pressure switch and set cover aside.

6. Remove the lamp by grasping the lamp
connector and rotating counter-
clockwise to unlock the lamp from the
nut (Fig. 14).
7. Once unlocked, slowly pull the lamp
straight up and away from the quartz
sleeve until it clears the vessel (Fig. 15).
Carefully place the lamp(s) in a safe
location while cleaning the quartz sleeve.
CAUTION: The UV lamp is sensitive to
handling and should be allowed to fully cool
before being moved. Wait at least 30 minutes
after disconnecting power to begin the
removal process.

8. Slowly lower the new lamp(s) down into the
quartz sleeve (Fig.16). Once you have verified
that the lamp(s) are secured, reconnect the 4-
Pin Connector (Fig. 17 & 18) to the pins on top
of the lamp(s).
NOTE: The ceramic 4-Pin Connector is
designed to fit onto the end of the lamp in
ONLY ONE ORIENTATION. Clean and re-
lubricate the O-ring before reinstalling the
enclosure cover.
9. Place the plastic electrical cover on the top of
the HydroRite unit and tighten the screws using
a Phillips screwdriver (Fig. 19 & 20). Plug in the
power cord. Turn on the circulation pump,
making sure to open any valves (if applicable)
that were closed. Verify that the lamp is lit.

Cleaning The Quartz Sleeve: Automatic
When using an automatic cleaner, the HydroRite’s quartz sleeve can be cleaned with no need to
disassemble the Cell Vessel. When the user initiates a cleaning, an acid bath will clean the quartz
sleeve. The cleaner will be permanently plumbed into the system; connected to the inlet and outlet
ports located on the top and bottom sides of the vessel.
Muriatic Acid: Use a diluted mixture of 4 parts water to 1 part Muriatic acid (20º Baume
hydrochloric acid 31.45% by weight). ALWAYS ADD ACID TO WATER, and do so slowly.
Cleaning Procedure:
1. Shut off pool filter pump.
2. Close the two 3-way valves
(page 5) to isolate the vessel
from the pool system.
3. Open inlet and outlet port
valves, if used.
4. Start the automatic cleaner and
run the acid wash pump for no
less than 30 minutes to fully
clean the system.
