Electrical Connections - Hayward hydrorite uvo3 Owner's Manual

If using a chlorine erosion feeder or other chemical feed-
ers, install a check valve (see diagram on page 3) to iso-
late the vessel from the feeder, preventing chlorine from
backfeeding when the pump is off. For salt chlorinators,
a check valve is not necessary because those systems
stop producing chlorine when the pump is off.
After plumbing is complete, run the filter pump and
check for leaks in the HydroRite loop and the bypass
loop. Address any concerns before making electrical
connections.

Electrical Connections

Do not plug in the electrical power cord until all wiring
is complete.
There are 2 wiring connections between the controller
and the HydroRite vessel. In addition, a connection must
be made at the controller from the flow switch.

Vessel Connections
To gain access to connectors, remove the four screws securing the large vessel cap (cover).
Remove the cap. Make your connections and route the cables through an appropriately
sized cutout. The cap can then be replaced and secured. Refer to the information below
and the diagrams on this page for connection locations.
Venturi Tube
Insert the 3 ft. venturi tube into the ozone manifold as shown above. Note that the tube
can be cut to a shorter length to aid in installation. To avoid leaks, be sure to make a clean
square cut so that the tube fits into the ozone manifold properly.
The venturi tube is made of a specific material suitable for its purpose. If replacing the
tube or if a longer tube is needed, call Hayward Technical Support at 908-355-7995.
Ballast Cable and UV Lamp
DO NOT TOUCH THE UV LAMP WITH YOUR BARE HANDS. Gloves are included with Hy-
droRite and must be used when handling the lamp. There is a single ballast cable from
the controller that connects to the UV lamp (packaged separately). This cable must be
connected to the lamp BEFORE inserting the lamp into the vessel. Because of the different
size tabs on the lamp, it will only insert one way into the vessel. After fully seating the lamp
into the vessel, twist the lamp/cable clockwise about 1/8 turn to lock it into place. Route
the ballast cable through the appropriate cutout.
Ozone Tube
Insert the UV lamp's ozone tube into the back of the ozone manifold as shown above. Note
that the ozone tube can be cut to a shorter length for easier routing.
Interlock Cable
The Interlock prevents lamp operation when the cap is removed. The two conductor inter-
lock cable attaches to the square connector at the end of the pigtail shown above. Find the
appropriate cutout and route the wire through.
Replace Vessel Cap
After making the above connections and routing the cables through the proper cutouts,
replace and fasten the cap.
