review with all appropriate personnel to
ensure continuous compliance.
These safety requirements are
MANDATORY.
Failure to carefully follow these re-
quirements can cause injury to the
operator and damage the UV unit.
1. Release the pressure in the UV treatment chamber
before attempting to remove the protective covers
and sealing items.
2. Disconnect all power to the UV unit before
servicing. The unit operates on high voltage and
should only be serviced by qualified personnel.
3. Do not look at the lighted blue ultraviolet lamps.
Do not operate the ultraviolet lamps outside of the
UV treatment chamber. Exposure can severely
burn and damage eyes and skin.
4. Supply the unit with the correct voltage and
frequency as indicated on the nameplate decal,
ensuring the unit is wired in accordance with local
electrical codes.
5. Properly ground the unit. Failure to comply may
result in severe or fatal electrical shock.
6. Install the unit away from undue vibration that can
damage the electrical components and UV lamps.
7. Ensure all water connections (flanges and compres-
sion nuts) are tightly sealed before applying
pressure to the UV unit. Do not stand in a direct
line with the end of the unit when inspecting for
water leaks; observe from the front or back.
8.Do not allow the unit to overheat by operating
without water flow. Normal operating temperature

SL series
The SL Series is the appropriate choice for many low
volume indoor applications because it offers a compact
footprint and easy installation. All three models
combine the electrical components and the treatment
chamber in one integral unit.
SL-10A
This unit mounts vertically. Inside the cabinet housing
are the ballast and the UV treatment chamber. The
housing has a front cover which allow access to all
interior components. On the side of the treatment unit is
a knockout for electrical input power.
SL-1
This unit mounts vertically. Inside the cabinet housing
are the ballast and the UV treatment chamber. The
housing has a front cover which allows access to all
interior components. On the side of the unit is a
knockout for electrical input power.
MP-2-SL
This unit mounts horizontally. Inside the electrical
housing are the ballast and two UV treatment chambers.
They operate serially, as this is the most efficient
design. The housing has a front cover which allows
access to all interior components. On the back is a
knockout for electrical input power.
treatment chamber
On both ends of the UV treatment chamber are gasketed
end plates which contain the stainless steel nipples,
compression nuts, O-rings and lamp socket retainer
assemblies. (This option is for RA finish cylinders).
Each treatment chamber is fitted with two raised-face
stainless steel flanges (in the case of the MP-2-SL, each
chamber has one flange each). The bottom flange is
always designated as the inlet, while the top flange is
the outlet.
Inside the inlet flange is a helical baffle that prevents
laminar flow and maximizes the unit’s performance.
The quartz sleeves fit inside the UV treatment chamber
through the threaded nipples. The UV lamps fit inside
the quartz sleeves. The lamp sockets connect to the
lamps, providing a waterproof seal and a vibration-proof
grip.

Aquafine equipment is guaranteed to be free from
defects in materials and workmanship (excluding
ultraviolet lamps) for a period of one year from the
date of purchase. Any part suspected of being
defective should be returned prepaid to Aquafine
Corporation. If upon our inspection, the part(s)
proves to be defective, it will be replaced or repaired
(our option) and returned to sender prepaid.
Before returning any part, contact Aquafine
Corporation for return authorization and shipping
instructions. This guarantee is void if the equipment
has not been installed and maintained in accordance
with instructions. This guarantee is in lieu of all other
warranties, expressed or implied.
To keep your warranty valid and to ensure peak
performance, fill out and return your warranty
registration card (located in the back pocket of
this manual) and use only genuine Aquafine
replacement parts.

operating pressure
Standard units are rated for a maximum operating
pressure of 120 psig (8.24 bar).
If your unit has the High Pressure Modification option
(model number suffix “HP”) operating pressure may
increaseto150psig (10.34 bar).
heat sanitization
Forheat sanitization(temperaturesexceeding 170°F
(77°C)uptoamaximumof 194°F(90°C)),itisrecom-
mended that stainless steel compression nuts be used in
place of CPVC compression nuts.During heat sanitiza-
tion the S-254 probe must be removed. (Adaptor
available for maintaining Hydrostatic seal during
sanitization.) The selection of the elastomers should
be considered.
intermittent operation
Never operate the unit without water flow. Permanent
damage is caused to the UV lamp(s), electronic ballast
and related components without water flow.
Operating the ultraviolet unit without water flow
through the chamber automatically voids the war-
ranty.
If operated without water flow, the fluid within the
ultraviolet chamber will become hot causing the UV
lamp(s) to lose effectiveness. The heat can permanently
damage the ultraviolet lamp(s). The heat can also damage
the lamp ballast and related instrumentation.
Should the unit be used for specific batch flow opera-
tions, it can be turned “on” and “off” manually. Make
sure the unit is allowed to warm up for at least one
minute before use, and make sure the unit is turned
“Off” after each session. Do not exceed 3 on/off cycles
per 24 hour operation.
If you need help to determine the best method of operat-
ing your UV treatment unit under intermittent conditions,
contact your local representative or the factory.
An optional Temperature Safety Control Device is available
to prevent the overheat problems described above.
where to install the unit
Install the UV treatment unit in a horizontal position
in a sheltered area with ample ventilation. Ambient
temperatures surrounding the unit should be between
35oF (2oC) and 110oF (43oC). Should your requirements
differ, contact the factory for assistance.
As an ultraviolet UV treatment unit does not introduce
any chemical residue within the water, it is desirable to
install the unit as close as possible to the point-of-use in
order to avoid potential recontamination by discharge
pipes, fittings, etc. The base of the UV treatment unit
should be mounted on suitable support to avoid undue
strain on the unit or your related pipes and fittings.
Verify the location is free from vibration which could
be caused by proximity to heavy equipment, erratic or
improper pumps. Excessive vibration will damage
internal electrical components and cause premature
failure of the UV lamps.
Allow sufficient service access clearance. In making
your plumbing connections, provide unions, valves,
bypass and drain.
Please allow at least 40” of clearance on the lamp
changing end of the unit.
how to protect your unit
The location should be free from undue vibration which
could be caused by proximity to heavy equipment,
erratic or improper pumps. Excessive vibration will
damage internal electrical components and cause
premature failure of the UV lamps.
Limit overhead piping load to 10 lbs (4.54 kg) per
flange. 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 the extreme momentary
pressure may rupture and fracture the quartz sleeves.
A parts check list was included when this unit
was shipped. Please refer to this list and note
that some parts are small and can be easily
overlooked when discarding packaging.

special piping requirements
for users of ultrapure water
Ultrapure water users have reported that over time,
exposure to ultraviolet light may photochemically
degrade nonmetallic piping materials, including most
or all fluoro-polymers, resulting in material breakdown
and/or structural failure.
Should your water application and piping material be so
classified, we recommend you install “UV light traps”
to isolate any such susceptible material from direct
exposure to the ultraviolet light. One common practice
is to install stainless steel 90oelbows at the inlet/outlet
of the UV treatment chamber prior to the connection of
any nonmetallic materials. UV light traps protect
nonmetallic piping. Should you require any additional
assistance, please contact your local Aquafine represen-
tative or the factory directly.
wiring the unit
A 1/2” conduit knockout (7/8” dia.) has been provided to
attach a field installed junction box. This box should be
directly attached to the enclosure. All wiring connec-
tions must be made within this junction box. The size
and type of junction box should be made in accordance
with local and applicable codes.
GROUNDING
IT IS IMPERATIVE THAT THE UNIT BE
PROPERLYGROUNDEDFORSAFE AND PROPER
OPERATION.
Failure to properly ground the UV treatment unit
automatically voids all equipment warranty.

these quartz sleeve installation procedures:
1. Turn off all power to the unit.
2. Wear clean cotton gloves to prevent contamination
of the quartz sleeves.
3. Carefully remove the quartz sleeve from the factory
packaging. Handle with care as they are fragile.
4. Visually inspect all quartz sleeve(s) for cracks or
other damage. Do not install damaged quartz
sleeve(s).
5. Remove the covers from the treatment chamber.
6. Remove all compression nuts and any packaging
material from the end plate (if installed).
7. Place the end of the quartz sleeve into the threaded
nipple and slowly push the sleeve into the chamber
through to the second end plate.
8. Install the compression nut and o-ring by placing
the o-ring into the internal relief of the compression
nut below the threaded area. The o-ring should fit

CAUTION! Prior to energiz-
ing the ballasts and lamps,
ensure there is no water
leaking into the quartz
sleeves and compression nut
cavities by properly installing
these components. Even a small leak can
flood a quartz sleeve and compression nut
cavity.
During operation, high voltage is present
at the lamp pins and receptacles of the
lamp connectors. Prolonged flooding of a
quartz sleeve and compression nut cavity
can cause premature failure of the lamp
due to repeated arcing, overheating of
the lamp connector cable, and may result
in a meltdown of the cable insulation.
installing the UV lamps
Once is has been verified that there are no leaks in the
system, the UV lamps are ready for installation.
1. Removeall power to theUVunit.
2. Depressurize the system.
3. Wear clean cotton gloves to prevent contamination of
the UV lamps.
4. Carefully remove the UV Lamp from the factory
packaging. Handle the lamp with care, as it is fragile.
5. Insert one UV lamp into each open quartz sleeve
and push it about 2”-3” (51-76mm) out beyond the
opposite compression nut, so as to be able to hold
the lamp with one hand.
6. Unscrew and pull back the retainer cap from the
rubber lamp socket.
7. Insert the lamp base into the rubber socket. Push
until you feel a firm “bottomed out” connection.
8. Carefully slide the rubber boot portion of the lamp
socket over the end of the lamp. CAUTION: DO
NOT INSERT UV LAMPS WITH OPPOSING
RETAINER CAP IN PLACE. Verify no portion
of the rubber boot has folded under during this
process.
9. Screw the slotted retainer cap clockwise onto
the compression nut, making sure the number
on the socket lead wire and the end plate
correspond.
10. Connect the right side rubber lamp sockets and
spring-loaded lamp socket retainer assemblies onto
each lamp. Pay special attention to match the
numbers on the retainer assemblies with the
numbers beside each steel nipple on the end plate.
11. Carefully pull out each rubber lamp socket from
each spring-loaded socket retainer assembly.
12. With one hand, push the rubber socket boot onto the
end of each ultraviolet lamp. When properly
attached, a slight “snap” can be felt, which indicates
a proper connection.
13. Carefully slide each lamp socket retainer assembly
up and over the rubber lamp socket boot, until the
retainer assembly reaches the male-threaded portion
of the compression nut.
14. Then, turn clockwise until the socket retainer cap
bottoms out against the compression nut. Avoid
overtightening.
Step5: Insertlampinto quartzsleeve.
Step13:Slidelampsocket retainerassemblyoverboot.
Step 8: Slide boot onto lamp socket assembly.

UV lamp operational
display panel
To verify that all the UV lamps are operating properly,
your UV treatment unit has been provided with a UV
Lamp Operational Display Panel. The panel consists of as
many LED indicators as there are ultraviolet lamps. Each
LED indicator is electrically connected to the lamp
circuitryof a specific UVlamp.TheLED indicators are
intended to operate “on” when the UV lamps are also
turned “on”.
Should any UV lamp fail to operate electrically, the
correspondingLED willautomaticallyturn “off”.
Each UV lamp is numbered at the end of the UV
treatment chamber, and the corresponding LED light
carries the same number on the display panel; thus, if
one or more LED lights fail to operate, you can easily
determine which specific lamp requires attention.
We recommend you monitor the LED Panel daily to
ensure proper performance.
Runningtime meterwithlamp LEDindicator.
prior to turning on the
UV unit, verify the following:
• With water flowing through the system, ensure there
are no system leaks and no piping connection leaks
• All earth ground connections are properly made
• All lamp connections are properly made
1. Verify that all incoming power conductors, including
the ground conductor, are properly terminated.
CAUTION! Rapid succes-
sive cycling of the power to
the ballasts can cause
premature failure of the
system components.
running time meter
Your ultraviolet treatment unit has been furnished with a
Running Time Meter, located on the front instrument
panel. This non-resettable running time meter will log
up to 99,999 hours. It is intended to remind you of the
number of operating hours on the equipment, as certain
maintenance functions need to be performed at certain
time intervals.
A maintenance log is attached to the unit for your use. It
should be kept current. This provides an immediate
maintenance reference: when it was performed and
when the next service is due. Additional service logs are
available from Aquafine, and are intended to be placed
on top of the existing service logs.
2. Turn on the electrical power to the UV unit.
3. Turn the power off until actual operational start up
begins.

model S-254 UV optical sensor
The optional S-254 UV optical sensor measures the
relative output of ultraviolet
light within the UV treat-
ment chamber. Degradation
of the UV lamps, fouling of
the quartz sleeves, and
increased turbidity of the
water will affect the sensor
reading.
The UV meter assembly and
instrumentation setpoint
potentiometers are located on
the electrical enclosure.
The peripheral alarm
contacts are accessible
from the back side of the
meter. A shielded signal
cable connects the sensor
meter assembly to the sensor probe. The sensor probe
is located in the sensor port fitting on the UV treatment
chamber.
The meter must be reset after the first 100 hours of
operation on new UV lamps, both at the time of installa-
tion and each time the UV lamps are replaced.

ALARM CONTACTS (OPTIONAL)
Normally Closed and Normally Open alarm contacts are
also provided for use with user-supplied peripheral
equipment, such as remote alarms or solenoid valves.
Dry relay contacts are rated as follows: 0.52 AMP 120
VAC., 0.25 AMP 240 VAC
If your application requires higher contact ratings,
use a slave relay. Connection of peripheral equip-
ment is the responsibility of the user.
See wiring schematic in back pocket of this manual
SENSOR ALARM
The S-254 UV optical sensor provides information
about the relative amount of UV passing through the
water. The reading is affected by quartz sleeve fouling
and/or the germicidal lamp efficiency. The UV sensor is
sensitive to, and reflects changes in, UV transmission
when a substantial change occurs in the normal
operating flow rate, temperature, operating pressure, or
quality of the fluid flowing in the system.
When the UV intensity falls below the minimum
standard due to any of the above conditions, the sensor
alarmlight(red LED) will come“on”andcorrective
action must be taken to optimize the performance of the
UVtreatmentunit.
1. Examine your system for any significant changes in
normal operating conditions.
2. Verify that all UV lamps are operating. Verify the
quartz sleeves are clean.
If quartz sleeve fouling has caused the optical sensor
alarm to activate, the quartz sleeves must be cleaned.
At the same time, you must clean the sensor probe
quartz window. Please find this information in the
maintenance section of this manual.

4-20 mA sensor signal
option
This option works with the optional S-254 optical
sensor. It generates a 4-20 mA output signal based upon
the relative UV intensity which may be monitored at a
remote control panel or control PC. The customer is
responsible for providing an appropriate 4-20 mA
display instrument and connecting it.
A second NEMA-rated enclosure is provided and
connected to the remote sensor enclosure. The cus-
tomer is responsible for bringing peripheral instrument
wires through the 1/2” electrical knockout on the bottom
of the dedicated NEMA enclosure and connecting it to
the indicated terminals.
T-120 temperature safety
control option
The Temperature Safety Control consists of a heat-
sensing probe. This device protects against inadvertent
overheating inside the UV chamber, which can damage
the UV lamps and the ballast/LED Display Panelcircuitry.
The Temperature Safety Control senses raised water
temperature and assumes the UV lamps are operating
“on” with no water flow.
STANDARD UNITS
The device automatically turns the UV lamps off when
thewater temperature reaches120ºF(49ºC)and auto-
matically turns the UV lamps back on when the tempera-
turefallsto100ºF(38ºC).
HIGH TEMPERATURE (HT) UNITS
The device automatically turns the UV lamps “off” when
thewater temperature reaches170ºF(77ºC)and auto-
matically turns the UV lamps back “on” when the
temperaturefallsto150ºF(66ºC).
This temperature spread prevents excessive stop/starts
during no flow conditions, and it protects the UV lamps
and the electrical components from overheating damage.
The temperature probe is located in the inlet riser. No
operator intervention is required other than periodic
visual verification that the UV lamp(s) are properly
operating during normal water flow conditions.
The cutoff temperature has been preset at the factory.
Should you require a different set point, please contact
Aquafine for assistance.
lamp out alert indicator
option
Lamp Out Alert is an optional accessory package that
activates a relay when a UV lamp fails to operate.
A visual inspection of the LED UV Lamp Display Panel
will indicate which lamp has failed. Dry contacts are
provided for customer connection. The dry contacts are
ratedat3.0Ampsmaximum @ 120 volts.
If the unit is equipped with the Lamp Out Alert Option,
thethree wires (COM,NC,NO) terminating fromthe
LOA must be filed terminated within a filed installed
junction box.
A main disconnect switch is also required, so that the
electrical power can be completely isolated from the unit
during servicing.
It is absolutely necessary that the unit be properly
grounded for safe and proper operation.

14
using the LED display
If an LED bulb does not light after you replace a UV lamp,
you need to verify the electrical output of the ballast
connected to that specific UV lamp. This is done by
testing the ballast open circuit voltage. This should be
done by an electrician or qualified facilities personnel.
Follow these recommended procedures:
1. Turn power “off” to the UV unit.
2. Remove the cover.
3. Identify the “faulty” UV lamp which corresponds to
the number on the LED display.
4. Remove the lamp socket(s) from the “faulty” UV
lamp base.
5. Use a voltmeter and set an operating range at >700
VAC.
6. Measure the open circuit voltage:
Fordouble-ended/andhigh-temperaturelamps:
connect one end of the voltmeter to one end of the
lamp socket and the other end of the voltmeter of the
opposite end of the lamp socket.
7. Turn power “on” to the UV unit.
8. Record the reading.
9. Turn power “off”.
10. Listed below please find the open circuit volt-
ages for the various ballasts:
If the voltage reading is zero or a number above or
below the acceptable ranges, this indicates a ballast
fault, and the ballast connected to the “faulty” UV lamp
must now be replaced.
If the voltage reading is within acceptable ranges but
the LED does not light, the LED board has failed and
needs to be replaced.
Refer to the Replacement Parts Lists in the back of this
manual to identify the proper ballast and/or LED part
number.
CAUTION! Avoid
touching the lamp tip
after you remove the
rubber lamp socket.
This is a shock hazard.

cleaning the unit
The exterior surfaces of the Aquafine UV unit should
be kept clean as part of routine maintenance. Use a soft
cloth with soap and water or any commercial stainless
steel cleaner. Avoid scratching the Lexan instrument
window.
LED status display panel
Monitor the Status Display LED Panel daily.
Immediately replace any failed UV lamp.
UV lamp replacement
Replace UV lamps after 8,000 hours of use.
THIS IS BASED ON NO MORE THAN 3 ON/OFF
POWER CYCLES PER 24 HR. PERIOD.
Please follow the operating requirements outlined in
the warranty section of this manual.
Premature lamp failure or lamp life deterioration can
be expected if the UV unit is cycled on/off more than
three (3) times a day. To replace the lamps, follow the
procedures on page 10.
The Colorguard™ ultraviolet lamps are rated for 8,000
hours of continuous use or 24 months of intermittent
use, whichever comes first. After this time, the lamp
glass will photochemically change and no longer allow
sufficient 254-nm shortwave UV, the germicidal ray of
the lamp, through the glass to effectively kill bacteria.
Failure to replace the ultraviolet lamps on a timely
basis of at least once every 8,000 hours may cause the
equipment to fail. With intermittent use, in no case
should the ultraviolet lamp be used for more than 24
months of operation without replacement, regardless of
the number of hours of operation, due to normal
operational degradation of the UV lamp.
CAUTION! Prior to remov-
ing the cover to access the
lamps and quartz sleeves,
you must release all pres-
sure to the UV treatment
chamber. Drain the cham-
ber if required. Do not stand in a direct
line with the end of the unit; observe
from the front or back of the unit.
quartz sleeve cleaning
& replacement
As water passes through the ultraviolet treatment unit,
minerals, debris and other substances in the water will
settle and deposit onto the quartz sleeve. This will
impair the ability of the ultraviolet rays to penetrate the
water.
If the water has been processed through deionization,
reverse osmosis, or distillation, the cleaning frequency
can be set at once per year. If clear, fresh water is used,
the probable cleaning frequency will be anywhere from
once every thirty days to once every six months. You
can determine this cleaning frequency. This is done by
visually inspecting any one quartz sleeve to see if any
debris or film has settle on the outside of the quartz
sleeve.
Recent studies have shown that degradation of the
quartz sleeve from continuous exposure to UV reduces
the amount of UV radiation transmitted into the water
stream. Based on these findings, we recommend the
annual replacement of the quartz sleeves in addition to
routine cleaning.
cleaning the quartz sleeves
Visually inspect a quartz sleeve thirty days after use to
see if any debris or film has settled on the outside. If
dirty, use the cleaning procedures that follow.

1. Shut off the flow and release the pressure.
2. Shut off all power to the UV unit.
3. Remove the coaxial cable by pushing and turning
the BNC terminal counterclockwise. The connector
willslideoff.
4. Twist and pull the probe from the sensor fitting.
5. Use a lint-free cloth with alcohol and very carefully
wipe the lens face on the front of the probe. Failure
to do so may result in false readings.
6. Replace the probe and the coaxial cable.
7. Turn the power on and resume operation. Whenever
new lamps have been installed, follow instructions
on page 12 under “Setting the UV Meter.”
ballast replacement
Ballast replacement is not part of the UV unit’s routine
maintenance. However, in the event that a ballast needs
to be replaced, the following procedure should be
followed:
1. Power down the UV unit by turning the unit isolator
switch, if installed, to the “OFF” position. If not,
ensure that power to the unit is removed by opening
the switch or breaker upstream of the UV unit.
2. Locate the old ballast to be replaced. Refer to the
electrical diagram, if necessary.
3. Isolate the old ballast from rest of system by discon-
necting the ballast connector.
4. Using 5/32 L-shaped hex wrench completely
remove the bolt securing the ballast to the sub
panel. Put the bolt aside.
5. Remove the old ballast by pulling it towards you.
Discard the old or defective ballast.
6. Install the new ballast, securing it with the bolt
removed earlier.
7. Tighten the bolt with 5/32 L-shaped hex wrench.
8. Reconnect ballast.
9. Restore the power to the UV unit by turning the unit
isolator switch to the “ON” position or by closing
the upstream switch or breaker.
measuring performance
Every UV treatment unit should be tested periodically to
verify actual efficiency. Regardless of the intended
application or any optional equipment which may have
been provided with your UV unit, the most accurate and
dependable procedure is to conduct post-UV sample
analysis in accordance with standard testing methods.
Periodic sample collection and testing should be
scheduled as often as the user deems sufficient to be
assured the quality of the Aquafine ultraviolet unit
effluent is acceptable.
obtaining proper
water samples
Our experience has shown that the vast majority of
unsatisfactory post-UV bacteriological samples are
directly related to improper sample-taking techniques.
There are a variety of commercial sample collection
apparatuses available, and should you choose one, be
sureto followthemanufacturer’s recommended
procedures.
1. Turn off the water to the unit.
2. Disconnect the electrical circuit.
3. Drainthe UV treatmentchamber.
4. Wear clean cotton gloves to prevent contami-
nation of the quartz sleeves and UV lamps.
5. Remove the lamp sockets.
6. Remove the ultraviolet lamps from inside the
quartz sleeves.
7. Using the appropriate compression nut tool,
loosen the compression nuts and carefully
remove the quartz sleeves.
8. Wash the quartz sleeves with mild soap and hot
water and rinse with clean, hot water.
Should this be insufficient to clean the quartz
sleeves, they should be replaced. To place an order,
contact Aquafine or your local representative. To
replace the quartz sleeves, follow the procedures on
page 9.

We have provided 1/4”NPT threaded fittings on both
the intake and discharge UV chamber flange risers. We
recommend you use these fittings to collect “before and
after UV” water samples to eliminate the possibility of
contamination by nearby piping, fittings, etc.
We recommend you select a valve with a discharge
orifice no larger than1/4”(6mm).
sampling procedures
The following procedure is recommended for collecting
samples for bacteriological analysis when sample valves
are installed:
1. Prior to taking the water sample, have on hand an
adequate supply of sterile bottles. These should be
obtained from a source laboratory and should have
been autoclaved and contained within a plastic outer
wrapping.
2. The inside diameter of a sample valve must not exceed
1/4”(6 mm)toensure proper velocity.Priorto taking
the sample, it is imperative that the test sample valve
be fully opened under full pressure for a full three and
one half minutes. Temporary tubing or some other
material may be used to direct the water to a container
or drain to avoid unnecessary spillage.
3. After the valve has been left fully open for three and
one half minutes, reduce the flow to a reasonable
streamofwater(notlessthan 50% of full flow).
Continue flowing to drain three additional minutes.
4. Remove any temporary tubing used for flow diver-
sion.
5. Open the sterile bottle. Holding the cap in a down
position, the operator should then hold his breath
while taking the sample so as to avoid atmospheric
contamination of the sample. The operator must also
not allow his finger to touch the inside of the cap or
the neck of the bottle.
6. After the water sample has been taken, the cap should
be immediately secured on the sample container.
7. The sample container should be labeled and placed in
a plastic wrapping and must be taken to the laboratory
for plating as soon as possible. Processing should
begin within three hours of sample collection and
should comply with accepted standard methods.
The above procedure was developed by a leading national
pharmaceutical firm after an 18-month study. It has been
more
found that virtually all removable debris which may
accumulate within a sample valve can be mechanically
flushed during the procedures detailed above.
We recommend duplicate samples be taken at each test
station, during each specific test, to avoid laboratory
error and to ensure reasonable repeatability and validity
through comparison.
