Please contact the factory concerning any questions or assistance that may be
The QU-series models are designed for low-flow rates and for specification
requirements listing alternatives to stainless steel wetted parts. The liquid
passes through a quartz sleeve disinfection chamber. The ultraviolet lamp is
located in close proximity to the furthest distance or outer wall of the quartz
sleeve chamber. Units can be mounted vertically or horizontally.
The ultraviolet disinfection chamber is quartz material with removable gland nuts.
The ends have CPVC threaded nipples, through which the quartz sleeve is
inserted and then tightened by use of o-rings and gland nuts. The ultraviolet
lamp is located outside the quartz sleeve. The inlet/outlet connections are ½ or
¾ inch FNPT and can be installed with liquid flow in either direction.
The QU series is fully customizable and can be configured as a single pass
system, 2 pass system, 3 pass system, or 4 pass system. The CPVC threaded
nipples are held in place with locknuts and can be added or removed at will.
The QU series enclosure is a powder-coated, galvanized steel enclosure with a
removable top panel. The top panel has a lamp view port and is safety
interlocked to de-energize power to the ultraviolet lamp when the top panel is
removed. The electronics are situated on a removable tray located inside the
enclosure, designed for quick removal/replacement for repair by field personnel.
1. Vibration of ultraviolet equipment will damage lamps and lead to
premature system failure. Choose a location for your UV Superstore
unit isolated from vibration. Potential vibration sources include heavy
equipment, poorly connected pipes and erratic or improper pumps.
2. Install the unit as close as possible to the point of use. Operating
pressure should not exceed 125 PSI. A water hammer may cause o-ring
failure. If your system is subject to water hammer conditions, we
recommend that you install a water surge suppressor.
3. The unit is designed to be installed vertically or horizontally with a
clearance at one end at least equal to the overall length of the chamber
plus 4” for removal of the quartz sleeve.
4. Temperature: Inlet water temperature should not exceed 100 degrees F.
Ambient temperatures in the area surrounding the Ultraviolet unit should
be between 25-90 degrees F.
5. Check ultraviolet unit and components. Lamps and quartz should be
handled with clean cotton gloves. Care should be taken that fingerprints
are not left on lamps and quartz. Clean with denatured alcohol
6. Be sure transmission of water meets acceptable standards.

7. Flow rate must not exceed rated capacity.
8. Before using the ultraviolet treatment unit, sanitize the unit through all
the discharge piping and fittings to the point(s) of use. Using a sanitizing
solution to remove any existing contaminants will give the unit a “clean
start”. Once sanitized, turn on ultraviolet unit and flush out the sanitizing
solution with ultraviolet treated water.
9. Adhere to the Maintenance Procedures as provided.
The units are designed to be installed in a vertical or horizontal position. The
quartz sleeve can be removed from either end.
The unit should be mounted properly to support the base of the unit while
eliminating possible strain on the mating pipe fittings. This unit comes with four
mounting holes. It is recommended when designing the plumbing schematic that
the units are installed using a union, by-pass valve system on both the inlet and
outlet connections.
Remove the gland nut(s) from each end of the disinfection unit. Slowly and
carefully slide the quartz through the DPVC nipple until it protrudes beyond the
nipples of both ends of the unit an equal distance. Place a lubricated o-ring over
each end of the quartz, and push the o-ring back until it stops at the nipple.
Be very careful when installing the gland nuts over the quartz sleeve. Tighten
the gland nuts by hand. NEVER USE PLIERS OR A CHANNELLOCK.
Gradually alternate tightening each end of the quartz sleeve. Fully tightening one
end first may cause the quartz sleeve to shatter. Make sure as you tighten the
gland nut that you maintain a clearance between the stop ridge machined in the
gland nut and the edge of the quartz sleeve. Hand tightening will provide the
required 125 PSIG seal.
After you have tightened the gland nuts and all other plumbing connections, open
the outlet valve. Slowly open the inlet valve and flush out all remaining air.
Then, close the outlet valve and slowly open the inlet valve fully, and check the
unit for leaks. If you find a leak at the gland nut, tighten the nut further. If the
leak continues, drain the unit and inspect the quartz o-ring and quartz for
possible damage. Once you complete checking the unit, carefully reassemble oring, and tighten gland nut. Re-pressurize the unit and check again for leaks.
If it becomes necessary to clean the lamp due to dust or fingerprints, please refer
to the Lamp Cleaning Procedure.
Insert the ultraviolet lamp into the lamp fixture. First insert one end of the
ultraviolet lamp into the spring activated lamp socket. Next, place the other end
of the ultraviolet lamp into the fixed lamp socket and allow the spring tension to
hold the lamp in place. The ultraviolet lamp is now installed.
The QU series is designed to be a highly flexible unit with additional passes
easily added for a higher flow rate, additional UV dosage, or in multiple vending
applications, to disinfect a different type of water (flavored water, vitamin added
water,, etc.).
An additional pass kit consists of the following components:
locknuts, 2 O-Rings, 2 Gland Nuts, and a Quartz Sleeve
2 nipples, 2
The QU series comes with 4 pass holes pre-punched on both ends of the unit to
accommodate up to four passes. To add a pass, unplug the power cord from the
end of the unit, open the cover and remove the lamp, and set it aside in a safe
place in order to avoid breaking the lamp when adding the pass. Choose a pair
of holes and remove the hole plugs from the ends of the unit. Insert the nipples
into the holes from the outside of the unit with the long end of the nipple facing
outward until the stop on the nipple butts up to the outer case of the unit. Secure
the nipple by tightening the locknut onto the short end of the nipple on the inside
of the unit. If hand tightening the nipple is not enough to secure the nipple,
gently tighten the locknut by tapping one of the tabs of the locknut with the end of
a screwdriver. Be careful to not over tighten the locknut as this can cause
the nipple to break. Once both nipples have been fastened into place, install
the quartz sleeve following the directions provided in the previous section.
The QU series comes with a standard output (400ma) lamp. However, in keeping
with the philosophy of having maximum flexibility, an optional high output
(800ma) lamp is available for the QU series. If you initially ordered the QU with
the high output option, no further wiring is needed.
If you desire to change the lamp from standard output to high output, or from high
output to standard output, some wiring modification will be needed. The ballast
used in the QU series will power either a standard output lamp (GS 692) or a
high output lamp (GS 692-HO). To power a standard output lamp, only one red
wire need be connected from the ballast to the lamp socket. To power a high
output lamp, both red wires need to be connected from the ballast to the lamp
For the high output lamp, both red wires with the female quick connect terminals
coming out of the ballast need to be connected to the two black wires with the
male quick connectors leading to the lamp socket.
The standard output lamp needs only one red wire connected to one black wire,
the other pair should be tied off. Do not connect both red wires when using a
standard output lamp. It will overdrive the lamp and cause premature failure.
Once again, no wiring need be changed, unless you are changing the type of
lamp from the one that was provided with your unit.
Keep a record of ultraviolet lamp replacement dates and servicing
We recommend sanitizing of the entire system after shutdown or
Lamp Replacement
The ultraviolet lamps are rated to provide 9,000 hours of continuous use.
After 9,000 hours the lamp hard glass sleeve will photo-chemically change
and the lamp will not allow sufficient amount of the ultraviolet wavelength
to destroy the bacteria. The lamps should be replaced when any one of
the following conditions occurs: 9,000 hours of use have elapsed or 12
months have passed.
Lamp Cleaning
If it becomes necessary to clean the lamp due to dust or fingerprints, the
lamps can be cleaned with denatured alcohol. Use clean cotton gloves
and a clean cloth when cleaning the lamps. Wait for lamps to cool before
Quartz Cleaning
Significant film or debris deposits formed on the quartz sleeves will impair
the ability of the ultraviolet rays to penetrate through the quartz and into
the fluid. To a great extent, your frequency of cleaning will depend upon
the water quality (i.e. amount of minerals present in the fluid). The more
minerals present in the fluid the more frequently the quartz will require
A periodic visual inspection of the quartz will be necessary to determine
the frequency of cleaning. Initial inspection should take place after thirty
(30) days of operation. If the quartz is dirty, shorten the cleaning intervals.
If the quartz is clean, lengthen the cleaning intervals.
To clean quartz sleeves, depressurize the unit by first turning off the
isolation valves on the inlet and then the outlet of the vessel. Remove the
power cord from the unit. Remove the gland nuts and o-rings from the
end nipples. Slowly and carefully slide the quartz sleeve(s) out either end.
The quartz sleeves may be cleaned with denatured alcohol. If this is not
adequate, a mild non-abrasive solution can be used. FRAGILE: Be
careful when handling quartz.
Whenever a quartz sleeve is cleaned, the quartz O-rings should be
replaced. Install the quartz sleeves with clean cotton gloves.
Removable Electronics Tray
The QU Series is equipped with a removable electronics tray for easy servicing.
It can either be removed for easy access for repair, or to be replaced with
another tray and the repairs done at another location.
To remove the electronics tray:
1. Disconnect the power cord from the end of the unit.
2. Remove the top cover from the unit.
3. Remove the four Phillips head screws holding the electronics tray to the
ends of the QU unit.
4. Disconnect the quick connect terminals from the lamp sockets on either
end of the unit. Remove the female spade terminal from the end of the
fuse. The tray can be slowly lifted out, exposing spade terminals
connected to the power cord housing. Remove the terminals connecting
to the power cord housing, and the tray can be removed. Caution! Be
sure to remove the power cord from the end of the unit. Voltages will
be present on some terminals if the power cord is not disconnected!
With the tray removed, internal parts are easily accessible. Replacement of the
tray is the reverse of removal
