generator to protect electrical components.
• Mount the DEL AOP 50 so that it is inaccessible to anyone in the pool.
Never attempt any servicing while unit is wet.
IMPORTANT INFORMATION

• WARNING Short-term inhalation of high concentrations of ozone
and long term inhalation of low concentrations of ozone can cause
serious harmful physiological eects. DO NOT inhale ozone gas
produced by this device.
• For your safety, do not store or use gasoline, chemicals or other
ammable liquids or vapors near this or any other appliance.
• To maintain cosmetic integrity, protect this unit from direct prolonged
sunlight exposure.
• To reduce the risk of injury, do not permit children to use this product,

Section 1 General Information
1A. Description
The DEL AOP 50 Ozone and UV Sanitizer System described in this
manual is designed to provide the benets of ozonated and UV
treated water in an environmentally safe and eective manner. The
high quality, specially engineered components ensure ecient water
sanitation output and reliable performance. As a result of proper
use, the DEL AOP 50 virtually eliminates the unpleasant eects of
traditional chemicals. The DEL AOP 50 ozone generators are safe and
harmless to your equipment when installed properly.

Section 2 Installation
2A.PoolPreparation
To achieve optimal performance from the ozone system, the pool
must be as clean as possible to start with.
1. Backwash or clean lters one day before starting the ozone
generator.
2. Superchlorinate pool water using a chlorine based shock
treatment so the water has a sustained 1-3 ppm free chlorine
level.
3. Test pool chemistry and adjust pH between 7.4 and 7.6. Adjust
total alkalinity between 80 and 120 ppm.
4. Run pool ltration continuously for 24 hours prior to starting
ozone system.
2B. Location
The DEL AOP 50 unit is designed for oor mounting. Locate the unit
in a clean, protected area, either indoors or outdoors (preferably
out of direct sunlight). If possible, locate the unit out of reach of
sprinklers or drainage spouts. Allow sucient access for maintenance
(2 ft clearance above and 1 ft around the unit) and all plumbing and
electrical hookups.

2C. Mounting
2C-1.FloorMounting
The DEL AOP 50 is shipped with the Mounting Feet installed in the
oor mounting position. Adjust the position of the feet if necessary
and tighten the screws. Mount the DEL AOP 50 to the equipment pad
through the slots provided in the feet using appropriate hardware for
the mounting surface.
2C-2.WallMounting
The DEL AOP 50 unit does not have holes for wall mounting but can
be mounted on the wall if desired.
1. Drill 4 holes, (.257 in, drill size F), in the back of the enclosure
approximately as shown in Figure 2.
2. Open door as described in SECTION 4C-1 and clean out debris.
3. Install Mounting Feet in drilled holes with hardware provided.
4. Mount unit to wall through the slots in the Feet using appropriate
hardware for the mounting surface.
2D.Electrical
2D-1.MainPower
Connect the DEL AOP 50 to the pool timing clock so that the DEL AOP
50 operates simultaneously with the pool pump. The DEL AOP 50 has
four available Knockouts for a 1/2” conduit tting, two on the back and
one on each side. Remove only the ideal Knockout for the installation
and install the proper conduit tting. Remove the Cover (Refer to
SECTION 4C-1) and locate the Terminal Block (Refer to Figure 5) on
the left side of the enclosure. Connect Line 1, Line 2, and Ground to
the Terminal Block as indicated by the label on the Generator Bracket.
Refer to the IMPORTANT SAFETY INSTRUCTIONS at the beginning
of this manual for important wiring information.
2D-2. Grounding Lug
Using a solid copper conductor, connect to the Grounding Lug on the
left side of the DEL AOP 50 to an appropriate earth contact.

Section 2 Installation
2E. Plumbing
The DEL AOP 50 can easily be added into the pool’s plumbing loop.
All the components are contained inside the enclosure so only the
water inlet and outlet need to be installed into the pool’s return line.
2E-1.PlumbingtheDELAOP50
The DEL AOP 50 must be installed in the pool’s main return line after
all other pool equipment (pump, lter, heater, and cleaner). The outlet
of the SEC (or MDV-100) must be at least 10 feet from the rst return
to the pool. Figure 3 shows the most basic installation. For installation
with additional sanitizers and pool cleaners, refer to Appendix A.
The DEL AOP 50 will come with one half of a union tting installed on
Inlet and Outlet, the other half of the ttings will be located in the DEL
AOP 50 parts bag. Use the union ttings provided to connect the DEL
AOP 50 inlet and outlet to your pool’s plumbing as shown in Figure 3.

Section 3 Operation
2E-2.PlumbingtheMixingDegasVessel(optional)
Under normal operation of the DEL AOP 50, bubbles will appear in
the return ow to the pool. To remove the bubbles from the ow, an
accessory Mixing Degas Vessel, or MDV, can be installed downstream
of the DEL AOP 50. The MDV-100 is designed for use with the DEL
AOP 50 and is recommended on indoor, covered, or vinyl-lined
pools. For more information, please call 1 [phone] and ask for
Residential Technical Support.
2E-3.WaterBackowCheckValve
If the pool equipment is mounted above the water line, a check valve
must be installed between the pump outlet and the Injector Manifold to
prevent the pump from draining and losing its prime (when not in use).
NOTE:If a 1/3# DELCheckTM is used, do not install immediately after
chlorine feeders.
3A.InitialSystemStart-Up
Upon completing all of the system connections and cleaning the pool
as outlined in SECTION 2, you are ready to start the DEL AOP 50.
1. Check electrical connections.
2. Turn on pool circulation system and verify the DEL AOP 50 has
power.
