ADDENDUM FOR CANADIAN TRIOPURE INSTALLATIONS
The following information is for Canadian installations of the TrioPure and takes precedence over other information
in the manual.
1. WARNING: Heavy pool (or spa) usage and higher temperatures may require higher chlorine output to maintain
proper free available chlorine residuals.
2. When replacing the cell, only use replacement cells having a label that clearly states that it is a replacement cell
for the chlorine generating device TrioPure-25, REGISTRATION NUMBER 28566, PEST CONTROL PRODUCTS ACT.
3. DO NOT add pool/spa chemicals directly to the skimmer. This may damage the chlorinator cell.
4. Maintaining high salt and chlorine levels above recommended range can contribute to corrosion of pool and
spa equipment.
5. Check the expiry date of the test kit. Test results may be inaccurate if used after expiry date.
6. WARNING: To reduce the risk of injury, do not permit children to operate this device.
7. Follow all aspects of the local and National Electrical Code(s) when installing the TrioPure-25.
8. With high bather loads or high temperatures, the pool owner may add “liquid chlorine” with the active
ingredient of Sodium Hypochlorite to supplement the Chlorine production in the TrioPure-25.
9. When properly maintained and cleaned and under normal use conditions, the life expectancy of the chlorinator
cell and electrodes is three years minimum - approximately 15, 000 hours of operation.
10. NOTE: For outdoor pools, chlorine residual can be protected from destruction by sun’s rays by addition of
cyanuric acid stabilizer. See Section 5 of the manual for recommended cyanuric acid levels.
11. When the TrioPure is used to sanitize a pool and spa combination, the spa must be completely drained

SECTION 1 General Information
1A Description
How Your TrioPureTM Sanitation System Works
Your TrioPureTM produces both ozone and chlorine. Ozone is
made by drawing air through Corona Discharge (CD) cells that
break down oxygen molecules, which then recombine into
ozone molecules. The TrioPure’s internal pump provides suf-
cient water ow through the TrioPureTM to draw this ozonated
air into the water stream. Chlorine is made by electrolyzing low
concentrations of salt water in the pool, freeing the chlorine
from the sodium chloride molecules in the salty water.
The TrioPureTM salt chlorination sub-system routinely shuts down
during cleaning mode and allows any scale that has developed
to slough off. This cleaning step dramatically lowers the amount
of scale that can attach to the salt chlorinator plates over
time and also greatly reduces the need for periodic cleaning.
The amount of chlorine produced by the TrioPureTM can be
adjusted by using the Chlorine Control knob in order to
compensate for higher chlorine demand during hot days or
increased bather load.

2B Installation Tips
CAUTION: The bypass manifold must be correctly installed or
your TrioPureTM system will not work properly and the warranty will
be voided. The bypass manifold contains two check valves that
are matched to create the correct backpressure and anti-siphon
protection for optimum performance of your TrioPureTM.
•••The TrioPureTM sanitation system should be installed on resi-
dential pools only. The salt level in your TrioPureTM pool should
be between 3,000 and 5,000 ppm (3,500 recommended).
•••If you use solar panels for pool heating, your TrioPureTM must
be plumbed with the manifold before the solar heater, and
the water return from the TrioPureTM after solar heater. The
bubbles that can be created through your solar heater can
inadvertently shut off the TrioPure-25. See Figures 1, 2, 3,
7, 8 and 9.
•• •The TrioPureTM must be installed no more than 2.4 m (8 ft.)
above water level or no more than 1 m (3 ft.) (measured from
the top of the enclosure) below water level to maintain the
correct pressure and ow characteristics for optimum opera-
tion of the unit.
•••DO NOT USE copper or iron piping for the TrioPureTM installa-
tion as chlorine and ozone have corrosive effects. Consult
your pool professional for appropriate pool equipment piping
materials.
••Even though the TrioPureTM is designed for outdoor use, care
should be taken when choosing a mounting location. To
protect your investment, mount the TrioPureTM where it is
protected from the elements (i.e., direct sun, rain, dirt, sprin-
klers) and completely sheltered if possible while providing
adequate ventilation.
•• •If ozone bubbles are not desirable (for indoor pools, vinyl-lined
pools, pools with covers, negative edge pools, etc.), the addition
of a DEL Ozone Mixing-Degas Vessel (MDV-30) is recommended.
Contact your local pool equipment dealer or visit DEL Ozone’s
website at www.delozone.com to nd one near you.
SECTION 2 Installation
The most common pool and pool/spa congurations are
discussed in this manual. For questions on your specic
installation, please contact DEL Ozone at 800-676-1335,
extension 293.

DEL Ozone · San Luis Obispo, CA 93401 · USA · 800-676-1335 · Fax: [phone]
•••“Salt & Pepper” ttings, eyeball ttings, or the use of a grav-
ity drains as return lines are recommended since they can
better mix and disperse treated pool water.
•••Plumb the TrioPureTM to the bypass manifold using a
minimum amount of plumbing fittings. This minimizes
backpressure.
•The TrioPureTM has been designed with an electronic water
ow switch. This device automatically shuts down both the
salt chlorinator and ozone subsystems when the water ow
through the TrioPureTM is interrupted. To prevent personal
injury and damage to the TrioPureTM salt chlorinator cell, do
not interfere with this system in any way. It is designed for
your protection and the protection of the TrioPureTM.
•••Always check the salt chlorinator cell frequently for the
accumulation of pool debris that may have bypassed the
pool lter. This can affect the operation of the ow switch,
ozone injector, pump, and salt chlorinator plates.
•• •Salt is not lost through evaporation, but is lost when water is
splashed out of the pool or during backwashing. Rainfall or
adding fresh water dilutes the salt concentration and you will
need to occasionally add more salt to the swimming pool. Check
salinity level before and after adding additional salt.
•••If the TrioPureTM is being installed on a new pool, do not add
salt for 2 weeks after the pool has been lled. This protects
plaster from staining and allows the nish to cure.

2-C Recommended Installation Materials
•Liquid tight conduit, connectors & junction box, and appro-
priately sized and rated wire per local electrical codes.
Note: The TrioPure is designed for 1.5 cm (1/2”) NPT liquid
tight ttings
•Two 5 cm (2”) unions for manifold installation to pool return
line (use reducer bushings for 3 cm (1½”)).
•2 cm (3/4”) unions, ball-valves, and rigid PVC or Spa-Flex
tubing for installation from manifold to TrioPureTM.
•Mounting hardware for securing TrioPureTM to a stable sur-
face (wall, fence, post with backboard) sufcient to support
the unit.
Note: If you are mounting the TrioPureTM to the side of house
wall that is located near a bedroom, consider using a vibra-
tion dampening material to reduce vibration noise.

SECTION 2 Installation (Continued)
2D Mounting the TrioPureTM
IMPORTANT: A qualied swimming pool professional and certi-
ed electrician must install the TrioPureTM Sanitation System.
Refer to local building codes for any additional requirements.
If you need assistance in nding a qualied installer, please
contact our customer service department at 1-800-676-1335,
ext. 293, or visit www.delozone.com.
Step 1 - Before starting, pick a mounting location that:
•
Is 3 m (10 ft.) ft. minimum from the edge of pool
•Allows space for ease of plumbing and electrical installa-
tion. Review Sections 2E & 2F.
•The bottom of the TrioPureTM has a minimum clearance
of 0.6 m (2 ft.) from all obstacles for ease of visibility and
maintenance. Space must be allowed on all sides of the
enclosure for adequate ventilation and to allow the clear
cover to open completely.
•
Sufficient clearance on top and both sides for your
TrioPureTM for plumbing and electrical hardware access.
•The top of the TrioPureTM is no higher than 2.4 m (8 ft.) above
or lower than 1 m (3 ft.) below the water surface.
••• Avoid installing your TrioPureTM above any heat generating
source such as a heater or pump.
•Meets the guidelines in Section 2E (Plumbing) and Sec-
tion 2F (Electrical) in this manual
•
It is recommended that the TrioPure is mounted with
¼-20 galvanized hex bolts. The bolt mounting pattern
is 254 mm (10 in.) wide by 375 mm (14.75 ft.) high.
Screw in bottom bolts so that the head is 6.3 mm (¼
in.) from the mounting surface. Slide the TrioPure onto
these bolts and screw the upper bolts through the top
mounting holes on the enclosure.
Note: If installing your TrioPureTM below water level, an addi-
tional light-duty check valve is required after the chlorinator
cell to prevent backwash in the unlikely event of ozone check
valve failure while the unit has been powered down.
Step 2 - Level and mount the TrioPureTM on a wall or a post.
If mounting the TrioPureTM on a post, it must be centered on
a flat panel of waterproof material at least 457 mm x 610
mm (18” x 24”). Do not enclose the TrioPureTM in any box. Do
not install it above any heat source. Install the TrioPureTM a
minimum of 3m (10’ ft.) from the pool edge. Do not install
the TrioPure in direct sunlight. In locations where the daytime
temperatures regularly exceed 37ºC (100º F), the internal
thermal protection switch may shut down the TrioPure. When
the temperature drops the TrioPure power will be restored.

· An automated shut-off valve needs to be put in the line between the bypass manifold and the TrioPureTM, which is tied into
the Pool/Spa control system, and shuts off water to the TrioPure when in spa mode.
- If this is overlooked, the TrioPure will pump water from the spa into the pool, when in spa mode.
- To minimize the size of ozone bubbles, use a dispersion cap or main drain cover. This may require a stub-up to the
appropriate size for the tting.
· Del recommends installing 2 cm ( ¾ ”) ball valves on the inlet and outlet of the Triopure to facilitate Salt Cell removal for
cleaning and a ball valve after the Bypass Manifold to control water ow through the Salt Cell.

Special Note about Spillway Valves on Pool/Spa Combinations without Solar. If a spillway valve is used, the line which takes water
from the pool into the spa creating the overow effect, it must be equipped with a light duty check valve to prevent water from being
diverted back into the pool, when in spa mode, and any lines to or from the TrioPure must be plumbed after it.

2F Electrical
IMPORTANT: Electrical connections must be made by a
certied electrician. Use copper conductors only. Follow
local and NEC codes. Connect only to a circuit protected by
a Class A GFCI.
Step 1 - Determine the voltage required for your installation.
Your TrioPureTM is congurable for either 120 V or 240 V AC.
Step 2 - For 120 V installations, install the 3.0 A fuse (3A G
type) into the fuse holder. For 240 V installations, install the
1.5 A fuse (3 AG type) into the fuse holder. The fuses are in a
bag attached inside the enclosure near the terminal block.
Warning: Failure to install the correct fuse voids the warranty
and can present a potential re and/or electrical hazard.
Step 3 - Open the front clear cover by opening the latch on
the right side of the enclosure.
Step 4 - Remove the front panel by pulling off the Chlorine
Control Knob and unscrewing four (4) Phillips head 6-32
screws. Locate the terminal block (TB-1).
Figure-10TerminalBlock120 VCongurations
Figure - 11 Terminal Block 240 V Congurations
Step5 - The main power wiring should be routed through 1.5
cm (½”) hole on the left side of the enclosure using appropriate
liquid tight strain relief or conduit (not supplied).
Step 6 - Connect the main wires to TB-1 as show in Figure 10
for 120 V installations or Figure 11 for 240 V installations.
Step 7 - Connect the local common bonding grid in the area of
the swimming pool, spa or hot tub to the bonding lug (on the
left exterior of the unit) with an insulated or bare solid copper
conductor not smaller than 8 AWG (US) or 6 AWG (Canada).
Step 8 - Attach the cover plate with the four (4) Phillips head
6-32 screws. Replace the Chlorine Control Knob onto the
extended “D” control shaft. Ensure that the ON/OFF switch
is in the “OFF” position. Close and latch the clear cover.
Note: The TrioPureTM must be hard-wired to the AC line side for
24 hour operation to 120 V/60 Hz or 240 V/60 Hz ONLY using
liquid tight ttings/conduit and wire gauges meeting local codes
for the voltage required. Use a permanent marker to indicate
either 120 V or 240 V conguration on the side label found on
the left side of the TrioPureTM.

SECTION 3 Pool Preparation
3A Important Information
If the TrioPureTM is being installed on a new pool, do not add
salt for 2 weeks after pool has been lled to help protect
plaster from staining.
Pool water must be at the proper salinity level, temperature,
and chemically balanced before operating the TrioPureTM.
3B What Kind of Salt to Use
Use 99.6% pure or better sodium chloride water softening or
feed salt work best with your TrioPureTM. The ner the grain,
the easier it will be to dissolve the salt quickly and completely
(pellets are much harder to dissolve than ne grain salt).
Common brand names of salt to use are Cargil and Morton.
Note: Salt with anti-caking agents (yellow prussiate of soda,
or “YPS”) may cause staining of pool linings and xtures and
should not be used.
3C Where to Get Salt
Salt can be purchased at a pool supply, building supply, feed
supply, or major home and garden department store.
3D How Much Salt to Use
Always use a salinity test strip (such as Aquacheck White for
salt or LaMotte Tracer Meter- found through local pool supply
dealer) or digital salinity meter to determine salt level in pool
water prior to adding any salt. Capture water from about 457mm
(18” in.) deep in a container, and then test this water sample. Add
enough salt to obtain a salinity of approximately 3,500 ppm - Refer
to ‘Salt Sizing Table’ (Figure 14) on pages 11-12.
3E How to Add Salt
Step 1 - Evenly disperse the proper amount of salt around the
perimeter of the pool. Run the main pool circulation pump for
24 hours and agitate any undissolved salt deposited at the
bottom of the pool with a pool brush. Allow 24 hours or longer
for salt to fully dissolve.
IMPORTANT: To avoid damage to your TrioPureTM chlorinator,
never operate the TrioPureTM if the salinity level is under 3,000
ppm.
It is easy to add more salt to your pool but difcult to remove
excess salt through draining.
CAUTION: Do not add salt to the skimmer box.
3F Pool Sizing Chart
If you don’t know the size of your swimming pool, you must rst
determine the volume before adding large quantities of salt.
For rectangular pools, simply calculate:
length (m) x width (m) x average depth (m) =
cubic meters (m3)
For oval pools, simply calculate:
length (m) x width (m) x average depth (m) x 1.1 =
cubic meters (m3)
For round pools, simply calculate:
(diameter(m))2x average depth (m) x 1.3 =
cubic meters (m3)

3H When to Add Salt
Step 1 – Determine the size of your pool in cubic meters. Please
see Section 3F.
Step 2 – Check the salinity of the pool water. Always use a
salinity test strip or electronic salinity meter to determine the
salt level in the pool water prior to adding any salt.
Step 3 – Use the Salt Sizing Table (Section 3G) to determine
how much salt you’ll need. You will also need to add about 0.6
kg (1.25 lbs) of stabilizer (Cyanuric Acid) for every 23 kg (50
lbs) of salt added to the pool. For example, if adding 340 kg
(750 lbs), the quantity of stabilizer needed would equal 340
kg (750 lbs) / 23 kg X 1.25 = 8.5 kg.
Note: To add Cyanuric Acid, slowly sprinkle into the skimmer.
Step 4 – Turn on the main pool pump with suction coming from
the main pool drain.
Step 5 – Add salt directly to the pool [DO NOT add to the skim-
mer box] by dispersing it around the outside edge of the pool.
Step 6 – Use a pool brush to mix and help dissolve the salt. Keep
the main pump running for 24 hours.
Step 7 – Check the pool salinity. If the salt level is much lower or
higher than expected, rst re-check your calculations for adding
salt. Second, check the pool for any undissolved salt and con-
tinue to brush and run the main pump as needed.
REMINDER: Even if the salt concentration is higher than 3,000
ppm, the ‘Low Salt’ light may ash if the water temperature is
at the low end of the specied range or the Chlorine Control
knob is at a low setting (1-4 shown on the LED display). This
is especially true during the initial preparation and start-up. In
this situation, the TrioPure may not display ‘10’ at the maximum
setting. The addition of more salt to the pool may allow the
Chlorine Output display to reach maximum readings.

SECTION 4 Operation
4A Initial Start-Up Procedure
CAUTION: Depending on water temperature and turnover in
pool, it may take several days for the salt to dissolve and salin-
ity levels to be measured accurately. Do not add additional
salt to pool unless all salt is dissolved and salinity measure-
ments are consistently less than 3,000 ppm.
CAUTION: Operating the TrioPure with pool salinity below
3,000 ppm will severely reduce cell life.
Step 1 - Before starting the TrioPure, manually add chlorine
to the water for the rst week to a minimum level of 1 ppm
and ensure that all water chemistry parameters are within
the specied limits. Check the water chemistry, water tem-
perature, and salt level (salinity) and adjust as needed – all
must be within the limits specied in Section 5B, Monitoring &
Maintenance, of this manual before starting the TrioPureTM.
Step 2 - Turn on main pool pump before starting the TrioPureTM.
Note: Ozone may cause temporary clouding of water in pool on
initial startup (rst 24-48 hours) as the ozone causes organic
matter to occulate (stick together) and minerals to precipitate
out so that they can be trapped in the pool lter. Clean lter as
needed until pool water is clear.
Step 3 - Become familiar with the controls, indicators, and
features of the TrioPureTM. See Figure 15 below (TrioPure-50
shown)

Step 4 - Unfasten the latch on right side of the TrioPureTM and
open clear cover.
Step 5 - Turn the Chlorine Control knob to ‘Min’
(Counter-clockwise).
Step 6 - Switch the TrioPureTM power switch to ‘ON’.
Step 7 - Observe the color of the following status LED lights:
Ozone Production cell
TrioPure-25 = O3Cell 1, O3Cell 2
Water Flow
Water Temperature
All above LEDs should be green. If any LEDs are red, please
see the Troubleshooting section, Chapter 6A for assistance.
Step 7a - Observe that the Chlorine Production LED display
reads ‘OF’.

Step 8 - Look for bubbles of ozone in the water at the injector
(found in the chlorinator cell).
Step 9 - Turn Chlorine Control knob up about half way (point-
ing straight up).
Step 10 - Observe Chlorine Production display: the Low Salt
light will ash and the display will read “0” until the TrioPureTM
chlorinator comes on line.
Step 11 - Check pool free chlorine levels every 24 hours, and
adjust Chlorine Control knob as necessary to get between
1.0 and 3.0 ppm.
