Introduction
Description
The HydroRite PVCUV system is a low-pressure, high-output amalgam, ultraviolet light sterilizer designed for commercial swimming pool applications. The system operates at light wavelengths of 254nm for sterilizing and 185nm for oxidizing. The HydroRite PVCUV is designed for commercial service and can be run 24 hours a day. The HydroRite PVCUV components are outlined below.
UV Light Chamber
The UV Light Chamber is made from highly polished 316L stainless steel lined PVC. Quartz sleeves separate the low-pressure, high-output amalgam germicidal lamps from the water. The water to be treated flows into the bottom of the chamber. Once in the chamber, the germicidal bulbs produce a minimum 3-log reduction in pathogens. The water is then returned to the source.
Power Supply
The power supply provides the current to start and maintain the germicidal lamps. A visual indication of bulb output is displayed on the face of the power supply, and a counter is located in the power supply to display hours of operation.

Installation
When installing, operating, and maintaining this equipment, keep safety considerations foremost. Use proper tools, protective clothing, and eye protection when working on or installing the equipment. Follow the instructions in this manual and take any additional safety measures appropriate. Be extremely careful in the presence of hazardous substances.
UV Chamber Installation
Place the UV Chamber on a level surface within 5 feet of the power supply. The chamber may be installed in a vertical or horizontal position. Ensure that the unit is accessible. U-shaped horizontal installations require that the water is plumbed going down into the inlet of the chamber and coming out in the up direction from the outlet of the chamber. Z-shaped horizontal installations should be plumbed so that the water flows up into the chamber and up out of the chamber. Vertical installations require that the water is plumbed going into the inlet of the chamber (bottom) and out of the outlet of the chamber (top). Secure the chamber with suitable hardware.
Quartz Sleeve Installation
Quartz sleeves are shipped with small rubber Hayward HydroRite PVCUV Light System stops inside the bottom of the sleeve. This rubber stop must remain in place to prevent damage from lamp installation. Place a gasket on the quartz sleeve quick disconnect flange. Carefully lower the quartz sleeve assembly into the chamber.
Quartz sleeves must be carefully lined up with the spring, or damage to the sleeve may occur. When the quartz sleeve is properly located in the spring assembly, the quick disconnect quartz sleeve assembly will rest about ¼” to ½” above the 2” gasket.
Gently press the quick disconnect quartz sleeve assembly into place and install the quick disconnect clamp to secure the sleeve in place.
Lamp Installation
The wiring connector for the lamp must be installed on the lamp before the lamp is lowered into the quartz sleeve, or damage to the lamp or quartz sleeve may occur. Place the connector onto the lamp and lower the lamp all the way to the bottom of the quartz sleeve.
Screw the viewing cap onto the quick disconnect quartz sleeve assembly. Push the lamp lead wire through the viewing cap until the lamp is against the rubber cushion at the bottom of the quartz sleeve, and tighten the liquid-tight gland.

The entire water volume of the circulation system should pass through the UV chamber. Plumb the inlet of the UV chamber as close to the outlet of the pool filter as possible. Plumb a bypass around the UV chamber to facilitate service. Use valves to isolate the chamber from the circulation system.
Plumbing The Flow Switch
Tap the ½ inch NPT flow switch into the Chamber inlet or outlet. Connect the flow switch wire to the connection on the side of the power supply marked Flow.
Plumbing The Air Bleed On Vertical Mount Chambers
- Insert the 3/8” elbow into the 3/8” female adapter (shown below) on top of the UV chamber.

- Tap the 3/8” NPT valve into the pump suction plumbing.
- Connect the two points with 3/8” tubing.
- Turn on the pool pump, then open the 3/8” valve.

Safety Cover Wiring
Place the safety cover on top of the UV chamber and attach it with the supplied nuts. Route the safety cover wire through the open liquid-tight gland at the bottom of the power supply.
UV Sensor Installation
Install the UV sensor o-ring, quartz window, and UV sensor into the sensor boss. Hand-tighten the UV sensor nut.
Operation
Start-Up Procedures
Open the chamber isolation valves and close any bypass valves. Allow the chamber to fill with water. Turn the system on with the switch located on the power supply. Operate the system for 10 minutes to allow the lamps to warm up to full power.
UV Meter Operation
The UV meter displays the UV dose in mj/cm². An adequate dose is 40mj/cm² to 60mj/cm².
The display will automatically calibrate with no input Hayward HydroRite PVCUV Light System required. When the UV dose falls to 39mj/cm²,² the green LED will go out and the yellow LED will illuminate. This indicates the need for quartz sleeve and sensor window service or lamp replacement. This indicates that service is critical.
Maintenance
Daily Check
Check the UV meter and LED lights on the power supply daily. If the UV meter falls below 40mJ/cm², the green LED will go out and the yellow LED will illuminate. The most common cause is dirty quartz sleeves and the sensor window.
Manually Cleaning Quartz Sleeve and UV Sensor Window (Non-NSF Models)
Carefully lower the quartz sleeve assembly into the chamber. Gently press the quartz sleeve into place and install the quick disconnect clamp to secure the sleeve in place.
Remove the UV sensor from the chamber and carefully remove the quartz window. Clean the quartz window by wiping with a clean cotton cloth and standard glass cleaner. Windows with calcium accumulation will require cleaning with a 5:1 water and muriatic acid solution. Reinstall the window and sensor. On models without the quartz window, clean the quartz on the face of the monitor.
Chemically Cleaning Quartz Sleeve and UV Monitor Window (NSF Models)
Unplug the unit from the power source to prevent the risk of electric shock or system damage. Isolate the chamber from the pool circulation system by opening the bypass valve and closing the inlet and outlet valves. Drain the chamber.
