Hayward HydroRite PVCUV Owner's Manual
Low Pressure UV Light System
Foreword
Congratulations on your wise investment. The Hayward® HydroRite PVCUV system is designed to provide substantially reduced chemical maintenance, improved compliance with Health Department operating standards, chemical cost savings, and many years of reliable operation. This manual should be read in its entirety before installation. Improper installation may void the warranty and create hazards. Familiarity with pool or spa filtration systems is presupposed. Ensure all recirculating pumps and heaters are turned off before installation. If the filtration system is below water level, adjust valves to eliminate pressure.
Installation is comparable to that of a chemical feeder. Pool contractors or maintenance engineers should possess the necessary tools and knowledge. Hayward's technical support line is available for assistance.

Sizing Guidelines
HydroRite PVCUV Sterilizers effectively treat water up to their maximum rated flow for the life of the lamp. UV sizing must comply with local codes. Consult your local health department or Hayward representative for specific requirements.
The following chart and temperature compensation formula determine the maximum system flow rate for satisfactory performance. Select the chart for your UV model and a flow rate based on the pool's % Transmittance (%T). If %T is unknown, use 95%. Compensate flow rate for temperatures below 88°F using the formula:
avT = average pool temperature
((100 - (88° - avT)) / 100) x GPM
Example for model HYR75, 95%T, and average pool temperature of 84°F:
((100 - (88° - 84°)) / 100) x 61 GPM = ((100 - 4) / 100) x 61 = (96 / 100) x 61 = 0.96 x 61 = 58.56 GPM
Flow Rate Charts (GPM vs. %T):
HYR75: A table shows %T values from 100 down to 75, with corresponding GPM values from 75 down to 31.
HYR150: A table shows %T values from 100 down to 75, with corresponding GPM values from 154 down to 67.

Installation
Keep safety considerations foremost during installation, operation, and maintenance. Use appropriate tools, protective clothing, and eye protection. Personnel must be familiar with this manual. Ensure the unit is powered off and disconnected, and all pressure is bled from liquid lines before servicing.
Consider the specific pump room layout and gather necessary tools and anchors for a smooth installation.
Power Supply Installation
WARNING: Support the power supply using a stud, not drywall anchors alone.
CAUTION: Avoid installing the power supply and lamp lead wire near sensitive electronics due to potential interference.
Mount the power supply within 5 feet of the UV chamber and within 3 feet of a 120-volt, 15-amp wall outlet protected by a ground fault circuit interrupter (GFI). Use studs for drywall installations and concrete anchors for concrete walls. Ensure the location is easily accessible.
UV Chamber Installation
Place the UV Chamber on a level surface within 5 feet of the power supply. It can be installed vertically or horizontally. Ensure accessibility. For U-shaped horizontal installations, water should flow down into the inlet and up out of the outlet. For Z-shaped horizontal installations, water should flow up into the inlet and up out of the outlet. For vertical installations, water enters the bottom inlet and exits the top outlet. Secure the chamber with suitable hardware.
Diagram Description: An illustration shows the UV chamber with "Outlet" and "Inlet" ports, indicating water flow direction.
Quartz Sleeve Installation
CAUTION: Lamps and quartz sleeves are delicate glass components. Wear cotton gloves when handling lamps, holding them by the ends only. Avoid touching the glass with bare hands; wipe fingerprints with alcohol.
WARNING: Quartz sleeves are shipped with small rubber stops at the bottom; these must remain in place to prevent damage during lamp installation.
Place a gasket on the quartz sleeve quick disconnect flange. Carefully lower the quartz sleeve assembly into the chamber, aligning it with the spring to prevent damage. The assembly should rest about ¼” to ½” above the 2” gasket. Secure with the quick disconnect clamp.
Lamp Installation
CAUTION: Install the wiring connector onto the lamp before lowering it into the quartz sleeve to prevent damage.
Attach the connector to the lamp and lower it 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 contacts the rubber cushion at the bottom of the quartz sleeve, then tighten the liquid tight gland.
Diagram Description: A diagram illustrates the "UV system installation diagram". It shows the water flow from the pump, through a filter, to the UV chamber (inlet and outlet), with a bypass line around the chamber. Components like the power box, UV chamber, flow sensor/switch, and safety covers are depicted.
Plumbing
Plumbing The Strainer (Optional)
The strainer can be installed on the outlet side of the UV chamber plumbing, anywhere in the return line downstream of the chamber outlet.
Plumbing The Flow Switch
Install the ¼ inch NPT flow switch into the chamber inlet or outlet, within the isolation valves. Connect the flow switch wire to the "Flow" connection on the power supply.
Plumbing The Air Bleed On Vertical Mount Chambers
- Insert a 3/8" elbow into the 3/8" female adapter on top of the UV chamber.
- Tap a 3/8" NPT valve into the pump suction plumbing.
- Connect the elbow and valve with 3/8" tubing.
- Turn on the pool pump, then open the 3/8" valve to bleed air.
Diagram Description: Illustrations show the installation of a 3/8" elbow fitting and a 3/8" NPT valve for air bleeding.
System Wiring
Ensure all systems are wired so that the HydroRite PVCUV powers off when the pool circulation pump is off, except for spray pads that might maintain bypass flow. 120-VOLT SYSTEMS are cord-connected with two standard plugs for a 15-amp wall outlet. Connect both power cords to a 120V electrical outlet protected by a GFI.
Operation
Start-Up Procedures
Open chamber isolation valves and close bypass valves. Allow the chamber to fill with water. Turn the system on using the switch on the power supply. Allow 10 minutes for lamps to warm up to full power. The UV monitor should read 60mj/cm² with the green LED illuminated.
UV Meter Operation
The UV meter displays UV dose in mJ/cm². An adequate dose is 40-60 mJ/cm². Upon initial power-up, the display shows a dose with both green and yellow LEDs off. After 10 minutes, it shows 60 mJ/cm² with the green LED illuminated. The display calibrates automatically. If the UV dose drops to 39 mJ/cm², the green LED turns off, and the yellow LED illuminates, indicating a need for quartz sleeve/sensor window service or lamp replacement. If the yellow LED is ignored and the dose drops to 30 mJ/cm², the yellow LED flashes, indicating critical service is required.
Maintenance
Daily Check
Check the UV meter and LED lights on the power supply daily. Under normal conditions, the UV meter should read over 40 mJ/cm² with the green LED illuminated. If the meter reads below 40 mJ/cm² and the green LED is off, with the yellow LED illuminated, maintenance or repairs are needed. Dirty quartz sleeves and sensor windows are the most common cause.
Manually Cleaning Quartz Sleeve and UV Sensor Window (Non-NSF Models)
CAUTION: Lamps and quartz sleeves are delicate glass. Wear cotton gloves when handling lamps, holding them by the ends only. Avoid touching glass with bare hands; wipe fingerprints with alcohol.
IMPORTANT: Quartz sleeves are shipped with small rubber stops at the bottom; these must remain in place to prevent damage during lamp installation.
Unplug the unit from the power source. Isolate the chamber by closing inlet/outlet valves and opening the bypass valve. Drain the chamber. Loosen the liquid tight gland, remove the viewing cap, and lift the lamp out of the quartz sleeve without disconnecting its wiring harness. Once free, disconnect the lamp from the harness. Remove the quick disconnect clamp and the sleeve from the chamber.
NOTE: If the power supply is within 5 feet of the UV chamber, the quartz sleeve may be removed without disconnecting the lamp.
WARNING: Follow all safety directions for muriatic acid. Always add acid to water. Use only with adequate ventilation. If strong odor is detected, stop work, ensure ventilation, and leave the area. Use a NIOSH-approved respirator for acid fumes if ventilation is inadequate.
Clean the quartz sleeve with a clean cotton cloth and standard glass cleaner. For calcium accumulation, use a 5:1 water and muriatic acid solution. Check the gasket on the quick disconnect flange. Carefully lower the quartz sleeve assembly into the chamber, aligning it with the spring to prevent damage. Gently press into place and secure with the quick disconnect clamp.
Remove the UV sensor and quartz window. Clean the quartz window with a clean cotton cloth and glass cleaner. For calcium accumulation, use a 5:1 water and muriatic acid solution. Reinstall the window and sensor. For models without a quartz window, clean the quartz on the face of the monitor.
Chemically Cleaning Quartz Sleeve and UV Monitor Window (NSF Models)
Unplug the unit. Isolate the chamber by opening the bypass valve and closing inlet/outlet valves. Drain the chamber.
Connect a HydroRite PVCUV Acid Washer or similar setup to the chamber. Mix cleaning solution at a 5:1 ratio of water to muriatic acid. Flush the chamber for 2-5 minutes with the solution. Drain the solution. The Acid Washer pumps the solution back into the tank for reuse. Remove hoses and close valves. Open inlet/outlet valves to restore circulation.
Diagram Description: An illustration shows a chemical cleaning setup with a tank, hoses, and connections to the UV chamber for cleaning solution inlet, outlet, and a drain.
Lamp Replacement
Lamps are designed for a service life of 13,000 hours and will require replacement thereafter.
CAUTION: Lamps and quartz sleeves are delicate glass. Wear cotton gloves when handling lamps, holding them by the ends only. Avoid touching glass with bare hands; wipe fingerprints with alcohol.
Unplug the unit. Loosen the liquid tight gland and remove the viewing cap. Lift the lamp out of the quartz sleeve without disconnecting it from the wiring harness. Once free, disconnect the lamp from the harness.
CAUTION: Install the wiring connector onto the lamp before lowering it into the quartz sleeve to prevent damage.
Attach the connector to the lamp and lower it to the bottom of the quartz sleeve. Screw the viewing cap onto the quick disconnect quartz sleeve assembly and tighten the liquid tight gland.
