READ AND FOLLOW ALL IMPORTANT SAFETY INSTRUCTIONS
When installing and using this electrical equipment, basic safety precautions should always be followed, including the following: This product should be installed by a professional service technician or similar person who is qualified in electrical equipment installation. Improper installation and/ or operation could cause serious personal injury, property damage or death. Improper installation and/or operation will void the warranty.

The device must be connected only to a supply circuit that is protected by a Ground Fault Circuit Interrupter (GFCI). FAILURE TO CONNECT THIS DEVICE TO A GFCI SUPPLY CIRCUIT COULD RESULT IN ELECTRICAL SHOCK CAUSING SERIOUS BODILY INJURY, INCLUDING DEATH. Disconnect all AC power before installation and servicing. 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.

This device is for swimming pool use only. Do not use this device for potable (drinking) water sanitization. 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.

CAUTION : ULTRAVIOLET RADIATION. Disconnect power before replacing lamp(s).
This device contains ultraviolet lamps 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 including blindness. DO NOT VIEW UV LAMP WHILE THE DEVICE IS IN OPERATION.

Philips head screwdriver

Installation

Before starting your installation, you MUST read this manual in its entirety in order to install your unit in a safe manner. Note that a few moments spent becoming familiar with the HydraPure unit and its installation may save a great deal of time (and expense) later. If you have any questions that are unanswered when you have completed the reading of this manual, contact your supplier or Hayward.
Installation of HydraPure requires mounting, plumbing, installing a venturi and flow switch (on the return side of the filter pump), and connecting the required electrical connection. Disconnect power to the pool filter pump before starting this installation. Installation must be performed in accordance with local and NEC code.

Determine a Suitable Location

The HydraPure must be mounted at least 5′ from the pool (more, if local codes require). The HydraPure should be installed after all equipment (pump, filter, heater) but prior to any chlorinators (salt cell, tablet feeder, liquid injection).

Plumbing Overview

Plumbing the HydraPure Unit

Attach the (2) PVC 2½” union nuts to the unit. DO NOT OVER TIGHTEN, OVER TIGHTENING WILL CAUSE THE UNIONS TO BREAK.
After cutting pipes to length, debur all cut pipe to ensure shavings don’t plug critical points internal to the unit. Use PVC solvent cement to glue pipes into the union sleeve. NOTE the inlet and outlet pipe positions.
2″ X 2½” reducer bushings may be used if using 2″ pipe.

Connecting Power to the HydraPure Unit

Corded 120V Hydrapure unit: Plug into GFCI outlet.
Hardwired 120V or 240V Hydrapure unit: Follow steps 1 & 2 below.

Thread L1, L2 (240V) or N (120V) and ground wire through conduit.
Attach wires to connections according to diagram below.

Position the Hydrapure Lid

The lid can be positioned in any four directions for better view of the control panel.

Remove the 4 screws and then carefully lift the lid.
Rotate the lid and replace it in the desired position. Replace the 4 screws.

CAUTION: Be aware that there is a delicate control ribbon cable under the lid. Take care when handling.

In some cases it may be necessary to use an alternate Ozone check valve. This prevents the Hydrapure unit from losing pump prime and draining down the equipment set. This would be necessary when the Hydrapure Unit is positioned with the base of the unit greater than 1’ above water level. In that case the inlet check valve must be changed based on the chart below.

Base of Hydrapure to water level	Check Valve Rating	Part Number
1’ or Lower	1.0 LB	005-402-2505-00
1’-3’ (30cm-90cm)	2.0 LB	005-402-2506-00
3’-5’ (90cm-150cm)	3.0 LB	005-401-2503-00
5’-8’ (150cm-240cm)	4.0 LB	005-401-2504-00

In order to change the Ozone check valve, the installer simply loosens and unscrews the tubing compression fitting, loosen and unscrew the Check valve from the venturi Inlet connection. Warning:
Be sure to shutoff the equipment before removing anything from the unit, and drain the unit using the winterizing plug. There may be water present in the Venturi if the unit has been cycled on.
Position the Hydrapure Lid

Startup

Turn on the pool pump and verify that there are no leaks. If there are no leaks turn off pump and proceed to step 2.
Turn on power to the HydraPure by turning on the breaker or plugging it in.
Turn on the pool pump, the HydraPure will switch on automatically when it senses water flow.

Maintenance

The quartz tube requires cleaning every 12 months to ensure optimal performance.

WARNING : Before cleaning, turn off all power to the HydraPure unit and pool pump. Allow at least 15 minutes for the lamp(s) in the unit to cool. Never remove the electrical enclosure cover without first disconnecting the power source from the HydraPure unit. Never remove the HydraPure unit’s cover without turning off the pump. Before removing lamps, you must wear protective rubber gloves and safety eye wear. Do not handle a hot lamp or serious burns will occur.

Turn Off Power to unit or unplug.
Remove screws to lid.
Remove single screw to electrical enclosure cover.
Disconnect UV lamps from ballast.
Remove spring clip.
Carefully lift the lamp assembly, including lamp holder, do not pull excessively on the lamp wires.
Turning counter-clockwise, unscrew the round sealing nut.
Remove the aluminum compression washer making sure not to lose the black gasket.

NOTICE: Do not touch the glass part of the lamp as body oils will create hot spots & greatly shorten lamp life. Inspect the quartz tube carefully for any cracks or chips and replace the quartz tube if any are found. Do not use any other O-ring for sealing the quartz tube. Never use any type of lube or sealing agent. Doing so can result in a leak and possibly damaging the UV unit.
Grip quartz tube with both thumbs inside and pull up. Once the O-ring breaks free, the quartz tube should lift out easily.
First, remove O-ring and discard. Use shower/ tub cleaner, CLR or equivalent, or a solution of white vinegar and water to clean the outside/ inside of the quartz tube. The quartz tube must be completely dried and clear of residue, replace with new O-ring before reassembly.
CAUTION: Do not use tools on the quartz tube. Wear gloves to protect your hands in case the tube breaks.
Gently lower the quartz tube into the unit until the Oring makes contact with the top of the black threaded sealing sleeve. Then place the aluminum compression washer and gasket on the quartz tube. Press down on the aluminum compression washer with an even steady pressure. Lift aluminum washer and check to make sure it is seated evenly around the circumference of the quartz tube. Replace aluminum washer
Screw on the quartz sealing nut to hand tight plus ½ turn. Turn pump on to check for leaks.
Confirm that there are no leaks then turn off pump.
Carefully replace lamps, spring clip and connect lamps to ballast.
Reattach electronics cover and the lid. Turn power on to unit and turn pump on.
**CAUTION: Do not stand over the unit when it is under pressure or when the pump is on.
