General Safety Instructions
WARNING - to guard against injury, basic safety
precautions should be observed, including the
following:
1. READ AND FOLLOW ALL SAFETY
INSTRUCTIONS.
2. DANGER - To avoid possible electric shock, special
care should be taken since water is present near electrical
equipment. Unless a situation is encountered that is
explicitly addressed by the provided maintenance and
troubleshooting sections, do not attempt repairs yourself,
refer to an authorized service facility.
3. Carefully examine the disinfection system after
installation. It should not be plugged in if there is water on
parts not intended to be wet.
4. Do not operate the disinfection system if it has a
damaged power cord or plug, if it is malfunctioning or if it
is dropped or damaged in any manner.
5. Always shut off water flow and unplug the disinfection
system before performing cleaning or maintenance
activities. Never pull on the power cord to remove it from
an outlet. Grab the plug and pull to disconnect.
6. Do not use this disinfection system for anything other
than the intended use (potable water applications.) The use
of attachments not approved, recommended or sold by the
manufacturer / distributor may cause an unsafe condition.
7. Intended for indoor use. Do not install this disinfection
system where it will be exposed to the weather. Do not
store this disinfection system where it will be exposed
to temperatures below freezing unless all the water has
been drained from it and the water supply has been
disconnected.
8. Read and observe all the important notices and warnings
on the water disinfection system.
9. If an extension cord is necessary, a cord with a proper
rating should be used. A cord rated for less Amperes or
Watts than the disinfection system is rated for may cause
over heating. Care should be taken to arrange the cord so
that it will not be tripped over or accidentally pulled from
the outlet.
1. SAVE THESE INSTRUCTIONS.
2. WARNING: The ultraviolet light given off by this unit
can cause serious burns to unprotected eyes and skin.
Never look directly at a lit U.V. lamp. When performing
any work on the U.V. Disinfection System, always unplug
the unit first. Never operate the U.V. system while the
lamp is outside of the U.V. chamber.
3. WARNING: The U.V. lamp inside of the disinfection
system is rated at an effective life of approximately 9,000
hours. To ensure continuous water treatment, replace the
U.V. lamp annually with the appropriate Aqua Treatment
Services U.V. lamp. Failure to comply may present a re
hazard.

Function
Description
GDS ©2019 • www.aquat.com
The GDS series has an unique design with an ultraviolet germicidal lamp housed within a single quartz sleeve surrounded
by a stainless steel pressure chamber. The chamber is fabricated out of 304 Stainless Steel.
These units come with an ultraviolet lamp designed with four pins at one end.
The quartz sleeve is intended to be placed through the disinfection chamber and will slightly protrude through the
threaded nipple. The ultraviolet lamp is placed within this quartz sleeve. The U.V. light shines through this specially
designed hard quartz sleeve for maximum disinfection efciency to meet the requirements for bacteria reduction in
potable water.
The inlet is located on the bottom of the chamber and the outlet can be on either side dependent upon installation. A
sight Port is provided for safe and easy view of operation. A bracket is secured to the wall and the chamber is held in
place by tightening the lock nut to both mounting bracket and chamber.
The function of this ultraviolet disinfection unit is to provide in excess of 99.9% reduction of all water borne pathogenic
(disease causing) bacteria.
Model ATS series have a number code designation correspondent to the maximum GPM
(gallons per minute) flow rate of the unit. I.E,- GDS-8 has a maximum flow capacity of 8 GPM.
Applications: GDS Units are designed to destroy micro-organisms in water supplies. The Ultraviolet lamp peak
radiation of 254 nanometer wavelength (nm) destroys or inactivates the D.N.A. (deoxyribonucleic acid) which absorbs the
Ultraviolet radiation, preventing cellular reproduction GDS units meet minimum dosages of 30,000 microwatt second
per square centimeter.
MAXIMUM CONCENTRATION LEVELS BEFORE ULTRAVIOLET:
Turbidity.................................5 NTU Hardness..........................................7 gpg
Color.......................................None Iron...................................................0.3 ppm
Manganese........................0.05 ppm pH....................................................6.5 - 9.5ppm
Important Note - Pre-ltration equipment may be required if these parameters cannot be maintained. Flow rate must not
exceed rated capacity of the unit.

Installation
GENERAL CONSIDERATIONS FOR ALL
DISINFECTION UNITS:
1. When installing the equipment, it is necessary that the
unit be isolated from vibration, heavy equipment, and
poorly connected piping.
2. Incoming water temperature to the unit should not
exceed 35° minimum to 110° maximum degrees Fahrenheit.
3. The operating pressure should not exceed 100 psi.
4. Before putting the unit into final operation follow
sanitation procedures as outlined in this manual for proper
disinfection. Sanitizing all discharge piping and fittings
with household bleach from disinfection unit to point of
use removes existing contaminants and gives the unit a
“clean start.” Be sure to rinse with U.V. treated water.
5. A proper flow control, included with the unit, must be
used to insure only the designated flow through the unit.
6. It is recommended to use UV resistant materials when
initially installing unit. The UV light can cause PVC or
other plastic materials to degrade. Becoming brittle, this
can compromise the pipe or fitting structural integrity.
GENERAL PRECAUTIONS TO BE FOLLOWED
AT ALL TIMES:
1. Always disconnect electrical power to any U.V. unit
before servicing.
2. Under no circumstances should personnel look at a U.V.
lamp in operation (EXCEPT through an external sight Port
lens located on the outside of the unit).
3. U.V. disinfection units must always be properly grounded.
The GDS series are always placed after the pressure tank
and any other type of treatment devices (i.e. softeners,
lters).
These units are normally installed in a vertical position in
an enclosed area with good ventilation. Allow clearance of
at least the unit’s length at one end for quartz sleeve and
lamp replacement. Four (4) anchor bolt holes are provided
for proper wall support. Use anchors with screws for
sufficient support (not included).
If your piping system is subject to impulse pressure resulting
in a “water hammer” condition, a surge tank or other means
must be provided to remove this condition; otherwise, this
extreme shock pressure condition may rupture or fracture
the quartz sleeve.
Make all plumbing connections to allow for ease of service.
Be sure to follow all local plumbing codes and U.V.
restriction requirements where specied by local authorities.
STEP BY STEP INSTALLATION:
1. Turn off the water before cutting into the water line.
2. Assess the installation (i.e. type of pipe, size of lines,
etc.) and obtain necessary plumbing ttings for installation.
Inlets and outlets on GDS units are 3/4” FNPT and 1”
MNPT. Use Teon tape on all threaded connections and
avoid over tightening.
Note: The ow control is a press in type. Each unit has
a 3/4” FNPT and 1” MNPT inlet/outlet machined so
the ow control can be easily inserted into the feed inlet.
Make sure the rubber part of the ow control is facing
outward from the feed inlet. Simply hand press or slightly
tap in the ow control until it sits on the inside ledge of the
machined feed inlet.
3. Make sure to allow enough room to install, replace,
and clean the quartz sleeve and lamp. Installing a water
shut-off valve before and after the unit is recommended
to make servicing easy.
4. After mounting, install quartz sleeve, o-ring, and lamp
per instructions. Turn on the water slowly, check for leaks,
and repair as needed prior to full service operation.
5. After the unit is full of water, plug it into a grounded
110V outlet. Observe operation through the safety sight
port. The lamp will show a bright blue glow. If any
problems are noted, consult trouble shooting guide.

Sanitation Procedure
continue to run pump if water doesn’t ow.
B. The high level of chlorine required to sanitize
a water system is corrosive to most metals and
chlorine solution must not be allowed to remain in water
system more than 36 hours before being completely ushed
from system.
8. After system has been completely ushed, perform a
bacteriological analysis on the water following all applicable
procedures.
NOTE: Always follow the sanitizing procedure required by
applicable state or local laws.
EPA Registered: Well sanitizer pellets are EPA Registered
for sanitizing potable water. EPA Registration No. 50510-1
LARGE DIAMETER WELLS:Dug or bored wells
should be disinfected in the same way as a drilled one. Lower
the water level as much as possible, remove the sand, silt
and debris, and then treat with the chlorine solution. Mix
thoroughly by circulating the water back into the well and
use the hose to rinse the interior lining of the well. Do not
try to disinfect an unprotected, unlined well because new
seepage or surface contamination will flow into the water
nearby as fast as you can disinfect it. Disinfect the pipeline
distribution system as indicated for drilled wells.
SPRINGS AND CISTERNS: Mix about ½ cup of
household bleach in 5 gallons of water and use this to
scrub the walls of the spring box or holding tank. With
a constant ow of fresh water from the spring, there is
probably no way of detaining the chlorine solution in the
reservoir for more than a few minutes. However, the
chlorinated water should ow through the pipeline to
disinfect the distribution system. Cisterns can be disinfected
in the same way but a source of clean water will be needed to
ush the dirty waste out of the system.
For additional information about how to protect wells and
springs and keep them from becoming contaminated, call or
visit your local Cooperative Extension ofce, or your nearest
certied water treatment specialist.
TABLE 1** Quantity of solution mixed - 5.25% available
chlorine (laundry bleach) for disinfecting
wells, or 52,500 P.P.M..
WQA recommends 50mg/l or ppm chlorine concentration.
Formula - C2 X V2 / C1 = V1
C1= Household Bleach (52,500 P.P.M.)
V1= Chlorine Amount Needed
C2= 50 mg/L V2= 80 gallons holding time
I.E. 50-ml/g X 80 gal= 4000/52,500= .08 gallons of chlorine (5.25%)
.08 gal chlorine (5.35%) X 128 (oz/gal) = 10.24 oz (5.25%)
Dug Wells - 3 to 4 feet diameter - 4 cups per foot of water
Drilled Wells - 3 to 8 inch diameter - 1 cup per foot of water
HOW TO DISINFECT A WATER SYSTEM:
Every new well, or existing water supply system that
has been disrupted for service or repair, should be
disinfected before it is returned to use. Water in the
well and storage tank should be treated with a strong
chlorine solution to destroy disease organisms. All pipelines
and xtures in the distribution system should be rinsed
and ushed with chlorinated water. Upon installation of
a U.V. disinfection unit or yearly bulb replacement service,
disinfection with chlorine to initially ush the system is
recommended to assure line sanitation prior to U.V. start up.
The source of chlorine can be ordinary household liquid
laundry bleach (about 5.25% available chlorine). The
quantity required depends on the volume of water to be
treated. The United States Environment Protection Agency
(EPA) indicated that about 100 parts of chlorine, by weight,
mixed in a million parts of water will destroy essentially all
water-borne disease organisms. Table 1 shows the quantity
of liquid bleach required to disinfect wells of various
diameters and depths.
DISINFECTION PROCEDURE:
1. Remove the cap or seal from the casing and measure
the depth of the water in the well, then refer to Table 2 to
determine how many chlorine pellets should be used. In
some instances removing the seal to measure the water can
be a difficult task, and it is easier to estimate well and water
depth from well log or other records.
2. Remove well cap and determine if there is an unobstructed
path from the top of the well to the water level. If it is not
possible to remove the well cap, remove vent or sanitation
access plug.
3. Drop one pellet into the well and listen to hear if it hits the
water. If the pellet hits the water, drop one-half the number
of pellets determined to be needed into the well. These will
sink to the bottom and sanitize the lower part of the well.
4. Mix the remaining pellets in a few gallons of water in a
CLEAN plastic container and pour the solution into the well.
5. In order to mix the chlorine thoroughly throughout the
entire water system, it is necessary to re-circulate the water in
the well. This can be accomplished by connection a hose to
an out side faucet that is located after the pressure tank. Use
hose to run water back down the well (this also rinses upper
portion of well). After about 15 minutes of recirculation the
water, a strong chlorine odor should be apparent. Turn off
hose.
6. Bypass water softener and filters and open each water
outlet in the water system until chlorine is present in water.
This procedure assures that all the water in the system is
chlorinated.
7. Allow the chlorinated water to stand in the system for
at least one (1) hour, and preferable overnight. After this,
open an outside faucet system until water runs chlorine free.
Repeat flush operation on each faucet in system.
NOTE:
A. Chlorine may break loose iron deposits, slime and organic
material. This material will make the water discolored. The
material broken loose may plug pump screens. Do not

Sanitation Procedure Continued
TOO MUCH CHLORINE IS BETTER THAN
TOO LITTLE: **In situations where it is inconvenient
to determine depth of water or diameter of a drilled well,
a minimum of 1/2 gallon of household bleach may be
used for wells up to 8 inches in diameter with estimated
to be less than 80 feet deep; 1 gallon should be used for
similar size wells with water deeper than 80 feet. In case
of a well yielding more than 50 gallons per minute, special
procedures are required. Seek the advice of a certied
water treatment specialist.
Wait a day or two before you have another sample tested.
Do not take a sample for testing if the odor of chlorine is
still present in water.
REMEMBER - To make your water supply safe:
• Locate your well properly.
• Protect it from surface contamination.
• Test water periodically for coliform bacteria. (Home-
yearly, Farm-2X yearly)
• Chlorinate, or lter and disinfect the water if necessary.
Plumbing Line Sanitation Only:
When installing an ultraviolet disinfection system, a
prelter with sump may serve as a source to sanitize the
water lines only. For whole system disinfection follow
procedure as outlined above.

Agriculture Cooperative Extension.
TABLE 2:
NOTE:
Pellets Weight = 1.14 gram each, 25 pellets/oz., 400 pellets/lb.
1 cup of pellets = 1/2 lb., or 200 pellets, or 8 oz.
To produce a 400 P.P.M. chlorine concentration, to sanitize
a water system, use one-half (1/2) pound chlorination
pellets for each 100 gallons of water in the system (1/2
lb/100 gal= 8 oz/100 gal= 200 pellets/ 100 gal= 1 cup
pellets/100 gal). Table 1 shows how many pellets too use
per 100 feet of water in various diameter wells.

Maintenance
to prevent breakage. Make certain that all nger prints are
wiped clean before reinstalling (see installation of the quartz
sleeve). Replace o-ring [ATS8-544(1)] every time a quartz
sleeve is cleaned or replaced. We reccommend replacing the
quartz sleeve once a year.
U.V. LAMPS:
INSTALLATION OF THE ULTRAVIOLET LAMPS:
**DO NOT PUT POWER ON AT THIS TIME!**
CAUTION: Never operate or look directly at U.V.
lamp outside the disinfection chamber.
Make sure unit is unplugged when installing or servicing
ultraviolet lamp. Remove any paper tabs on the U.V. lamp
and avoid allowing ngerprints and other debris to deposit.
Carefully place the lamp inside the quartz sleeve leaving
enough space to connect the socket connector to the lamp
pins. Then gently slide the brass dust cap over the end nut,
securing the lamp and protecting it from dust.
ULTRAVIOLET LAMP MAINTENANCE
REQUIREMENTS:
The U.V. lamp is rated for 9,000 hours of continuous use.
After this period of time, the U.V. lamp has undergone a
photochemical change. While the lamp will not normally
be burned out, the lamp quartz may no longer emit the
254-nm shortwave U.V. to effectively kill bacteria. Failure
to replace the U.V. lamps every 9,000 hours may cause
bacteriological breakthrough. Should the use of the
disinfection unit be intermittent, in no case should the
U.V. lamp be used for more than 24 months regardless of
the number of hours of operation due to normal shelf life
degradation of the U.V. bulb. Changing the quartz sleeve
should be done at the same time U.V. lamp replacement is
scheduled.
It is recommended that your water supply be tested
periodically (yearly) through your local health department or
approved certied laboratory.
ELECTRICAL:
The GDS series are furnished with 6’ line cord that will plug
into a 110V outlet. Electrical receptacles must be properly
grounded for safe operation. Improper grounding will void
any warranty.
When possible use a separate breaker to minimize voltage
uctuations and avoid accidental shut off. After unit is
installed and water is turned on, plug the unit into 110V wall
receptacle. View lamp operation through safety sight port
lens.
NOTE: Avoid exposing your eyes to U.V. light.
QUARTZ SLEEVE:
Installation of the quartz sleeve:
Always handle quartz sleeves carefully to prevent breaking
or chipping. The quartz sleeves are to be clean and free of
ngerprints before installing.
After unplugging the unit, remove the brass dust cap and
electrical connection at each end. Then remove each brass
end nut. Install the quartz sleeve through the stainless steel
threaded nipples with 0.5” sticking out on each end. Use a
small amount of plumber’s grease and install the o-ring
around the quartz sleeve. Avoid riding the o-ring on any
threaded part of the nipple. Hand-tighten each brass end nut
to form a compression seal around the quartz sleeve. Avoid
over tightening the nut, which may cause a fracture on the end
of the quartz sleeve. Under normal operation conditions,
hand-tightening will provide a 100 psi seal. Do not use any
devices to tighten end nut.
After you have tightened the brass end nut and all other
plumbing connections, open the outlet valve. Slowly open
the inlet valve and ush out all remaining air. Then close the
outlet valve and slowly open the inlet valve fully. Check the
unit for leaks. If you nd a leak at a brass end-nut, tighten the
brass end-nut further. If the leak continues, drain the unit and
inspect the quartz o-ring and quartz sleeve for proper seal.
Once you complete checking the unit, reassemble o-ring and
tighten brass end-nut. Repressurize the unit and check again.
REQUIREMENTS FOR CLEANING THE QUARTZ
SLEEVE:
As water passes through the U.V., minerals, debris and other
matter in the water may deposit onto the quartz sleeve. After
sufcient lm has formed on the quartz sleeve, the ability of
the ultraviolet germicidal rays to pass though the quartz sleeve
and into the water may be impaired. Therefore, it is necessary
to determine a cleaning schedule for the quartz sleeve. The
frequency will depend on the specic type of water conditions.
If the water has been processed through deionization, reverse
osmosis, or is distilled, cleaning may be required only once per
year. If untreated water is used, the cleaning frequency will
vary. A minimum of once yearly is standard recommendation
for cleaning and lamp replacement. Contact your local dealer
for scheduling this service. Your specic situation will vary the
frequency time according to the water quality of the home or
facility application.
QUARTZ SLEEVE CLEANING PROCEDURES:
To clean the quartz sleeve, turn off the water ow to the
disinfection unit, turn power off, and at a separate faucet or
valve relieve the water pressure from the UV. Then disconnect
the electrical service to the lamp pins. Carefully remove the
U.V. lamp. Loosen the end nut with o-ring and remove the
quartz sleeve. The quartz sleeve may then be washed with a
mild soap and hot water solution and rinsed clean with hot
water. Should this be insufcient to clean the quartz sleeve,
a mild acid may be used (i.e. vinegar). Be certain to follow
all recommended safety and handling procedures on the acid
container. It is important to handle the quartz sleeve with care

Sterile Water Sample Procedures
SUGGESTED PROCEDURE FOR OBTAINING
STERILE WATER SAMPLES:
Prior to taking the water sample, be sure to have on hand an
adequate supply of sterile bottles (as shown in Fig 1). These
sterile bottles should be obtained from a reputable laboratory
and should have been autoclaved and contained within a
plastic outer wrapping.
1. Prior to taking the sample, it is imperative that the sample
valve, faucets, etc. be opened at full force for a complete three
and a half minutes.
2. After the valve has been fully opened for three and one
half minutes, reduce the flow to a reasonable stream of
water. Flow to drain an additional three minutes.
3. Open the sterile bottle or sterile container being used.
Holding the cap in a down position, the operator should then
hold his breath while taking the sample so as to avoid oral
contamination of the sample. The operator must not allow his
finger to touch the inside of the cap or the neck of the bottle.
4. After the sample has been taken, the cap should be tightly
placed on the sample container.
5. The sample container should be placed in a plastic wrapping,
kept cool, and should be taken to the laboratory for testing as
soon as possible following the above procedure.
We recommend duplicate samples be taken at each test station
during each specic test so as to avoid loss of sample through
laboratory error and to insure reasonable validity through
comparison.
Check with your local laboratory to assure proper sampling
and submittal procedure.
