Safety Consideraons
Although your UV system has been manufactured to the highest safety standards, care must be
followed when operang and/or maintaining your system.
1. Before servicing this equipment, disconnect the power cord from the electrical outlet.
2. Energy given o by the UV lamp can be harmful to your eyes and skin. NEVER look
directly at an illuminated UV lamp without adequate eye protecon and always protect
your skin from direct exposure to the UV light.
3. For complete disinfecon, use ONLY genuine replacement parts.
4. Do not operate the unit if it has any damaged or missing components.
5. To avoid possible electrical shock, use only with a properly grounded electrical outlet.
6. Never perform any maintenance to the system unless you are comfortable in doing so.
Contact the manufacturer for service instrucons if required.
7. Do not use this system for any purpose other than what it was intended for. Misuse of this
system could potenally cause harm to the user or others.
8. Your system is intended to be installed indoors and away from leaking plumbing. DO NOT
plug the unit in if the system or any of the components are wet.
9. The disinfecon system should be directly installed into a ground fault circuit interrupter
(GFCI). If the use of an extension cord is required, the cord must be manufactured with a
minimum of 16 gauge wire and care should be taken to avoid potenal tripping hazards.
10. We recommend that a licensed plumber or cered technician install the system.
Before You Begin
The following will be needed for installing the UV system:
Tools
• Pipe cuer, hacksaw or other specialized tools required to cut into your exisng plumb-
ing (e.g. if you have PEX piping)
• Soldering tools (torch, ux, emery cloth and solder)
• Wrench (for ghtening ngs)
Other Materials
• Inlet/outlet connecons
• Teon™ tape

Water Quality Parameters
UV disinfecon is extremely eecve against microorganisms but only if the UV light can pass
through the water it needs to treat. This means that the quality of your water is very important
in order to ensure complete disinfecon.
Treated water should be tested for at the least the parameters listed below. If the water exceeds
the listed parameters AQUA FLO strongly recommends that appropriate pretreatment equip-
ment be installed (equipment required will depend on parameters being treated):
Hardness: <7 gpg (120 mg/L) – if hardness level is 7 gpg or slightly below the
quartz sleeve must be cleaned periodically in order to ensure e-
cient UV penetraon; if above the water must be soened.
Iron (Fe): <0.3 ppm (0.3 mg/L)
Manganese (Mn): <0.05 ppm (0.05 mg/L)
Turbidity: < 1 NTU
Tannins (organics): <0.1 ppm (0.1 mg/L)
UVT (transmiance): >85% (Please contact AQUA FLO if water has a UVT that is less than
80% for pre-treatment recommendaons)
You can have your water tested at a private analycal laboratory or by your local dealer. It is
always recommended to install pre-ltraon of at least 5 microns prior to a AQUA FLO UV disin-
fecon system.

AQUA FLO (Standard output lamp systems)
SYSTEM SIZING
The AQUA FLO rack-mount UV system is designed as a do-it-yourself (DIY) system with a single
inlet and outlet port. This system comes fully assembled with the excepon of a single stainless
steel hose connecon that comes unaached, yet fully taped for easy installaon. PLEASE NOTE
that increasing the ow above this rang or disinfecng water that does not meet the quality
parameters will decrease the dose and therefore compromise the microorganism inacvaon.
To determine the ow rate, follow these simple steps:
1. Be sure no water is being used in the home.
2. Open a faucet or tap nearest the pressure system and run unl the well pump starts.
3. Close the faucet and using a second hand watch, record the length of me in seconds unl the
pump stops. This is known as the cycle me.
4. Then using a container of known volume, preferably in US Gallons, open the faucet or tap
nearest the pressure system and measure the amount of water drawn o unl the pump starts
again. Depending on the size of the container used, it is acceptable to turn the faucet on and o
to empty the container. This measurement is known as the draw down.
To calculate the pressure system ow rate divide the draw down by the cycle me and mulply
that by 60.
Draw Down__________÷ Cycle Time____________ x 60=__________Pumping Rate in USGPM
Locaon
Choose a locaon where the main cold water line is accessible. The system must be installed
aer other water treatment equipment (i.e. soener), but before any branches (See Figure 1).

PLEASE NOTE: All AQUA FLO UV disinfecon systems are intended for indoor use only as they
should not be exposed to the elements. The controller will require a ground fault circuit inter-
rupter (GFCI or GFI) outlet and should be mounted beside or above the reactor.
Orientaon
This system has the ambidextrous capability of being able to have the main water inlet enter
from either the le hand side or right hand side of the unit. The units comes pre plumbed from
the factory for a le hand water inlet. To change to a right hand water inlet follow these simple
steps (See Figure 2):
Step 1: Remove the blue lter sump housings (either one or two housings depending on the
model purchased) from the lter head and set aside.
Step 2: Remove the lter head screws from the top mounng plate (4 screws for a single lter
model and 8 screws for a double lter model).
Step 3: Carefully lower the lter head (or heads) from the rack assembly and rotate 180 de-
grees. Reassemble onto the rack assembly and take note of the arrows located on the top of the
lter heads indicang water ow (which now should be indicang a ow direcon of right-to-
le).
Step 4: Remove the stainless steel UV reactor from the two plasc clamps located on the top
of the rack. Carefully remove the top straps securing the reactor with the aid of a standard (slot)
screwdriver). Rotate the reactor 180 degrees (with the inlet now facing to the le and the lamp
connecons located towards the right) and place back into the cell clamps and re ax the two
top straps.
In either the le or right conguraons, to facilitate lamp removal, ensure there is enough space
at the lamp connector end to safely remove the UV lamp and/or quartz sleeve (See Figure 3).

Installaon
Step 1: Once both the orientaon and locaon have been selected, securely fasten the rack to
a suitable backing. As the rack system is extremely heavy when lled with water, it is imperave
that the rack be mounted with suitable fasteners for the parcular installaon.. Mounng to a
drywall backing is not suitable, unless the rack is fastened directly to the wall studs.
Step 2: The use of a by-pass assembly is recommended as it will allow you to isolate the UV
system This will allow for easier access in case maintenance is required.
Step 3: For water supplies where the maximum ow rate is unknown, a ow restrictor is rec-
ommended so that the rated ow of your parcular AQUA FLO system is not exceeded. The ow
restrictor should be installed on the inlet port of the reactor.
Step 4: It is recommended to have a licensed plumber connect the UV reactor to the water
supply and may be a requirement depending on where you are located.
Step 5: Connect both the inlet and outlet to the rack system with the applicable connecons
based on your parcular plumbing requirements. The inlet port of the lters is a 1” FNPT connec-
on and the outlet port of the UV reactor is a 1” MNPT connecon.
Step 6: Once the system has been plumbed in, gently remove the quartz sleeve from its pack-
aging being careful not to touch the length with your hands. The use of coon gloves is recom-
mended for this procedure as oils from the hands can leave residue on the sleeve and lamp
which can ulmately block the UV light from geng to the water.
Carefully slide the sleeve into the reactor unl you can feel it hit the opposite end of the reactor.
Align the sleeve so it centered along the length of the reactor, then gently push it in to lock it into
the internal centering springs in the far side of the reactor. CAUTION: Pushing too hard when the
sleeve is not aligned can damage the centering springs. Slide the o-ring onto the sleeve unl it is
bued up against the reactor (See Figure 4).

Step 7: Hand ghten the provided gland nut over the quartz sleeve onto the threaded end of
the reactor. It has a posive stop to prevent over-ghtening. A rm force may be required to fully
ghten the gland nut, but DO NOT USE TOOLS for this step. Insert the provided stainless steel
compression spring into the quartz sleeve. The spring works with the lamp and lamp connector
to create the proper lamp alignment. PLEASE NOTE: DO NOT install a UV lamp inside the quartz
sleeve without the sleeve spring in place.
Step 8: Install the lter cartridges in their appropriate housings. For the AQUA FLO branded
products, please refer to the chart located on page 12 of this manual. PLEASE NOTE: This chart
indicates the correct cartridge posion for the default “le-hand” orientaon with the water
inlet located on the le side of the rack system. If the orientaon was switched, the cartridge
placement must also be switched. Once the cartridges are in place, use the supplied lter wrench
to “snug” the lter housing onto the lter head (See Figure 5).
Step 9: Install the UV sensor (AQUA FLO6.0 systems only). Align the at poron so it faces the
gland nut end and matches up with the half metal lip on the sensor port (see Figure 6). Insert the
sensor so it is fully seated and hand ghten the sensor nut. Insert the sensor connector into the
IEP port located on the right side of the controller (Figure 7). For the sensor to be recognized by
the controller, the controller power must be plugged in last. Do not plug the controller power
cord in before the last step.
