4. Installation Manual
Selecting the Best Location for the Diffusers
For best results one of the ceramic diffusers should be submerged in the cooling tower
basin near but not on the pump intake screen. If bubbles inter the pump intake they may
cause cavitation (pump noise). The other twin diffuser should be placed at the opposite
end of the tower basin. If the DS-3 is installed on a twin cell tower system place one
diffuser set near the pump intake screen of each basin.
Caution:
The ceramic diffusers are very delicate and will easily break if handled
incorrectly. Handle with care.

Ideal location for 1 Diffuser is
near pump intake screen
Place the other at the opposite
end of the sump.

Mounting Your FlowMark DS-3 Enclosure
Select a location that is within 25 feet of the diffuser location in the tower as the tubing
provided is 25 feet long. The enclosure if fitted with four stainless steel mounting feet and
should be installed upright on a solid wall or other structure. The enclosure is rated
Nema 4X (water and corrosion resistant) but air intake and fan holes have been installed
on the bottom to allow oxygen to enter and heat to exhaust from the enclosure. Be sure
the enclosure is at least two feet off the ground to prevent water from splashing up to the
bottom and the enclosure is not lying flat on the ground where water could enter the box.
Connecting and Routing the Tubing
The tubing connects between the blue Lamp hambers and the diffusers so you must find
an opening that will allow both tubes to enter the sump area of the cooling tower.
aution: Make sure you do not kink the tubing as this will restrict disinfecting gas flow to
the diffuser.
If an opening is not available to route the tubing inside the tower you may have to route
them under or through the cross-flow cooling tower fill. If the fill is too close to the bot-
tom of the tower a length of 1” PV pipe will help with the install. Push the pipe straight
through the tower fill and then slide the tubing through the pipe. Once the tubing has
penetrated the fill you can then pull the pipe back out of the fill.

owering the FlowMark DS-3 System
Systems are supplied with a molded 10 foot long 110 VA Power ord that can be plugged
into any 110 VA wall outlet. If you choose to hard wire the unit simply cut the male plug
off the power cord and wire the three wires accordingly:
White: Hot Leg
Black: Hot Leg
Green: Ground
Power Requirement: Voltage: 110 VA
Amperage: 1.5 Amps.
Testing the FlowMark DS-3 System
Once the unit is installed and connected to the diffusers you are ready to turn it on.
Unlatch the two latches on the DS-3 ontroller to open the door and turn on the Breaker
Switch. There is a spring loaded safety button that must be pushed on the latches before
you open them. Do not force the latch without pushing the spring loaded safety button.
The Green Power Light on the face of the controller will illuminate when the system is
energized. The Yellow Treatment Light will illuminate indicating the Ultraviolet Lights are
on. The white color barb connectors at the bottom of the Lamp hambers will also
illuminate a light Blue color when the Ultraviolet Lamps are operating.
Confirm Bubbles in Tower Basin
Once the system is powered up and running for two minutes, confirm the twin ceramic
diffusers are producing a fine screen of disinfecting gas bubbles.
Green Light = System is Powered Up
Yellow Light = UV Lamps ON.
Barb Fittings will glow Blue
when the UV Lamps are ON.

Lamp Replacement
The blue lamp chambers contain special Ultraviolet Lamps that split oxygen molecules O2
into single molecules O1 to create the disinfecting gas. The useful lamp life is 8,760
hours (one year of continuous operation). After the one year term the light will continue to
shine but it’s ability to split oxygen molecules is degraded so the lamps must be replaced.
Order two new pre-assembled replacement lamps from your FlowMark distributor.
There is no need to remove the blue Lamp hambers.
1. Simply unplug the weatherproof 4-pin connector at the top of each Lamp hamber.
2. Unscrew the Lamps from the hambers. The Lamps were installed hand tight from the
factory but may need a pair of channel lock pliers to remove them after time.
3. The new Lamp threads are pre-wrapped with Teflon tape. Gently insert the new lamp
into the chamber and hand tighten. If pliers are used do not tighten more than 1/8th
of a turn.
4. Reconnect both 4-pin connectors. Push until you feel a click.
Diffuser Maintenance
During each cooling tower maintenance visit be sure to confirm a strong stream of bub-
bles are coming from the diffusers. It is possible the diffuser may need cleaning from
time to time. Submerge the diffusers in Muriatic acid for a few minutes and then rinse
with water.

Warning: Do not touch the lamp
glass with your fingers as damage
may occur.
Warning: Do not connect the light
and power the system with the
lamp out of the chamber. UV light
will damage your eyes and skin.

Trouble Shooting
Green and Yellow Lights OFF: heck the unit is plugged in. Re-Set circuit breaker inside
DS unit. heck building circuit breaker and/or GFI and RE-set.
Green Light ON - Yellow Light Dim: UV Lamp disconnected or defective. heck both UV
chambers to confirm the translucent hose barb connections are glowing Blue. Replace de-
fective UV Lamp.
Green Light ON - Yellow Light OFF: heck both UV chambers to confirm the translucent
hose barb connections are glowing Blue. Identify which lamp is not ON and trace wiring
back to the blue Ballsts inside the controller. Replace the defective ballast and re-test.
Pump Running but NO Bubbles at Diffusers: Open the enclosure and confirm air pump is
running. heck hose connections. If no air is flowing order a new pump from your Flow-
Mark dealer.
ir Pump is Not Running but Power Light is ON: Defective pump. Order a new pump
from your FlowMark dealer.
Note: UV Lamps, Ballasts and Air ump are designed for easy field replacement.
Hour Meter
Your DS system is fitted with a digital hour meter to monitor run time. If the system is
turned off or power fails the e-prom memory will remember the last reading and restart at
the last reading. After 9,000 hours replace the UV Lamp and then use a pen tip to press
the button seen in the photo above. onfirm the reading resets back to zero.
