Before you Begin
The Hayward HydroRiteTM HYD-UVO is designed for use in residential swimming pools and spas; it must not be used in potable (drinking) water installations. Use
of this product in applications other than swimming pools and spas will void your warranty and could be harmful to your health or the health of others.
How the Hayward HydroRite 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 so created is introduced into the water stream using a venturi. Ozone, a strong oxidizer and bactericide, works together with the UV to oxidize bather
waste and inactivate microorganisms utilizing a process known as “advanced-oxidation”.
When the HydroRite is creating Ozone, bubbles will appear within the HydroRite vessel and may also be seen at the return jets in the pool. At flow rates below
35 gpm, Ozone creation will stop and the bubbles will disappear. Although low flow rates will prevent the creation of ozone, the longer exposure time to UV
light within the vessel will increase the efficiency and efficacy of the UV sanitization process. Consider these factors when setting run times and pump speeds.

Determine a suitable location
Installation of HydroRite system requires mounting the controller and vessel, plumbing the vessel, venturi and flow switch (on the return side of the filter pump),
and finally, connecting the required cables. Remove power to the pool filter pump before starting this installation. Installation must be performed in accordance
with local and NEC code.
The HydroRite vessel must be mounted at least 10 ft. from the pool. The controller must be mounted a minimum of 6 ft. horizontal distance (or more, if local
codes require) from the pool and has a 6 ft. power cord that must be connected to a GFCI protected circuit. Refer to the diagram above for lengths of other cords
and the venturi tube. Note that the vessel and flow switch will be plumbed into the return plumbing after the heater and all other equipment with the exception
of chemical feeders and chlorination systems.

The controller is designed to mount vertically on a flat surface with the cables facing downward. Because the enclosure also acts as a heat sink (disperses heat
from inside the box), it is important not to block the four sides of the controller. Do not mount the controller inside a panel or tightly enclosed area. If the supply
or a lamp cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
After ensuring that the controller’s cables can reach their destinations, mount the controller to the intended surface using proper mounting hardware given the
size and weight of the unit. The controller’s mounting brackets require a total of 6 mounting bolts to fasten the controller to the mounting surface.
Plumbing the HydroRite System
Although not required, Hayward recommends that the HydroRite system be plumbed in a dedicated loop that can be bypassed as shown on page 3. A three-way
valve and actuator are supplied for this purpose. If plumbing a bypass, a tee fitting will be required. A bypass will aid in servicing and maintaining the HydroRite.
Note that the increased head of the HydroRite system may affect the performance of water features installed in the pool’s system. A bypass will allow you to
divert water directly to water features although be aware that the HydroRite will not sanitize under these circumstances.
Installation of 3-way valves on BOTH the inlet and outlet lines attached to the vessel plumbing is mandatory if an automatic vessel cleaner is used, or if the
vessel and associated plumbing is located below the waterline. Failure to use valves where any portion of the device is below the waterline will not allow the
device to be properly drained which could lead to cracking of the unit if any retained water freezes.
Securing the Vessel
When the vessel installation location has been determined, it should be secured to a concrete or wood base. Four mounting holes are located in the mounting
base of the unit that accommodates ¼ inch diameter bolts to mount the HydroRite unit in place. FAILURE TO PROPERLY SECURE THE UNIT MAY CAUSE NOISE
DUE TO VIBRATION CAUSED BY WATER PASSING THROUGH THE WET CHAMBER. Secure the vessel using bolts and anchors (not supplied) where necessary
and appropriate for your installation.
Plumbing the Vessel
The HydroRite vessel comes with union nuts and tails pre-assembled on
the housing. Remove the Inlet and Outlet nuts and note the orientation of
the orange gaskets when removing union tails. These will need to be put
back together after gluing the union tails to the pool piping.
After cutting pipe to length, slide one union nut onto the cut pipe and
glue the gray tail piece to the pipe end. Repeat for the other pipe. Thread
the union nuts onto the vessel and handtighten both unions. DO NOT
OVERTIGHTEN. OVERTIGHTENING WILL BREAK THE UNION NUTS. To avoid
stress on the connections at the vessel, piping should be supported and
should not rest solely upon the unions.
Plumbing the Flow Switch
The flow switch is a safety device that ensures that the HydroRite is only operating when there is water passing through the vessel. The flow switch must be
plumbed in the same section of plumbing as the vessel. Failure to properly install the flow switch can result in damage to the pool’s equipment.
IMPORTANT: There must be at least a 12” (30cm) straight pipe run before (upstream) the flow switch.
IMPORTANT: To ensure proper operation, verify that the arrow on the flow switch points in the direction of water flow.
Head Loss
Refer to the adjacent table below for Head Loss information.
Venturi
The venturi assembly is pre-assembled and ready to be plumbed. A 3 ft
hose connection is made from the venturi to the ozone manifold at the vessel
as shown in the diagram on page 3. More information about the venturi tube
and connection can be found on page 5.
Chlorination Systems
Care must be taken to prevent exposure of the vessel to high concentrations of chlorine. All in-line chlorine systems must be installed AFTER (downstream) the vessel.
