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 is 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 Pulsar strongly recommends that appropriate pretreatment equipment 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 Pulsar 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 Pulsar UV disinfec-
on system.

System Sizing
All Pulsar UV systems are rated for a specic ow rate in water that meets the quality parameters
on page 5. 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 ow rate follow these simple steps:
Be sure no water is being used in the home. Open a faucet or tap nearest the pressure system
and run unl the well pump starts. 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.
Then using a container of known volume, preferably in US Gallons, open the faucet or tap near-
est 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
For Point of Entry (POE) systems, choose a locaon where the main cold water line is accessible.
The system must be installed aer other water treatment equipment (soener or lters), but
before any branches (See Figure 1). For Point of Use (POU) systems, install the unit just before
the faucet. Pulsar recommends that a 5 micron lter be installed before the UV system for a nal
polishing step before the water is disinfected.
Figure 1. Recommended POE Installaon Locaon

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 2). The controller will require a ground
fault circuit interrupter (GFCI or GFI) outlet and should be mounted beside or above the reactor.
PLEASE NOTE: All Pulsar UV disinfecon systems are intended for indoor use only as they should
not be exposed to the elements.
Installaon
Step 1: The reactor can be installed either horizontally or
vercally using the clamps provided. Vercal installaon is
the preferred method with the inlet at the boom (lamp
connecon at the top) as it allows any air that may be in the
lines to be easily purged from the system.
Step 2: The use of a by-pass assembly is recommended as
it will allow you to isolate the UV reactor. This will allow for
easier access in case maintenance is required (See Figure 3).
Step 3: Use the supplied fasteners to mount the UV reac-
tor to wood or drywall. If mounng to an alternate material
you will need to purchase the proper corresponding fasten-
ers.
Step 4: For water supplies where the maximum ow rate
is unknown, a ow restrictor is recommended so that the
rated ow of your parcular Pulsar system is not exceeded.
The ow restrictor should be installed on the outlet port of
the reactor.
Step 5: 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 6: Once the system has been plumbed in, gently remove the
quartz sleeve from its packaging being careful not to touch the length
with your hands. The use of coon gloves is recommended 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 wa-
ter.
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 inter-
nal 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.
Figure 4. Quartz
Sleeve Installaon
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 UV sensor (“300” series 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 5). Insert the
sensor so it is fully seated and hand ghten the sensor nut.
Figure 5. UV Sensor Installaon Figure 6. IEP Connecon
Step 9: The reactor is now ready for water ow. When all plumbing connecons have been
completed, slowly turn on the water supply and check for leaks. Make sure the by-pass valves are
funconing properly and that the water is owing through the reactor. The most common leak
is from the o-ring not making a proper seal on the reactor. For new installaons, review steps 6
and 7. For older systems drain the reactor, remove the o-ring, dry it and reapply silicon grease.
Reinstall the o-ring ensuring that it is properly sealed against the reactor and check again for
leaks.
Step 10: Mount the controller to the wall so it is above or beside the reactor to ensure that no
moisture can deposit on any of the connecons (see Figure 1). Always mount the controller ver-
cally. For monitored systems, insert the sensor connector into the IEP port located on the right
side of the controller (Figure 6). 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.

Step 11: Always hold UV lamps by their ceramic ends, not by the lamp quartz. Remove the lamp
from its packaging. Again, the use of coon gloves is recommended. Remove the lamp key from
the lamp’s connector and set it aside for the next step. Be careful to not touch the key’s exposed
contacts. Insert the UV lamp into the reactor, being careful not to drop it.
Step 12: Install the lamp key into the controller (“200” series, “300” series systems only). The
key always comes packaged with the lamp and sits on the connector. With the key removed from
the lamp, orient it so the label is upright and facing you. The key will plug into the lamp key port
on the right side of the controller (Figure 8).
Step 13: Plug the lamp connector into the lamp. Note the keying for proper alignment (see Fig-
ure 7a, 7b). Insert the lamp connector into the gland nut and turn the connector approximately
¼ turn to lock the connector to the gland nut as in Figure 9.
Figure 8. Lamp Key Installaon Figure 9. Lamp Connector
Step 14: Tighten the capve ground screw to the ground lug on the UV reactor to ensure proper
grounding.
Figure 10. Ground Screw Connecon
Step 15: Your system is now ready to be plugged into the appropriate GFCI protected outlet.
Refer to the following secon before any water is allowed to ow through the system.

System Disinfecon
With a new installaon, or any me the UV system is shut down for service, without power, or is
inoperave for any other reason, the lines in the home or facility could be contaminated. Use the
following steps to fully disinfect the lines throughout the enre home or facility.
Step 1: Check for and remove any “dead ends” in the lines throughout the home as these can
harbor bacteria. Plug in the UV system and wait unl it is ready for operaon.
Step 2: Remove the lter cartridge from the last sump and ll it with 1-2 cups of household
bleach (most are 5.25% chlorine). Replace the sump and slowly turn on the water supply.
Step 3: At a water outlet, run the water unl bleach can be smelled. Repeat this for all faucets,
toilets, shower heads, refrigerators, outdoor taps, the washing machine, dishwasher, etc. at the
home or facility. Once nished, wait a minumum of 30 minutes before connuing.
Step 4: Reinstall the lter cartridge into the sump and ush the chlorine soluon by opening
all faucets unl chlorine can no longer be detected. Your home has now been completely disin-
fected with your Pulsar UV system ready to inacvate any microorganisms that enter the home.
Cleaning the Quartz Sleeve
Depending on the water quality, the quartz sleeve may require periodic cleaning. At a minimum,
the quartz sleeve should be cleaned on an annual basis. The following steps outline a basic clean-
ing procedure.
Step 1: If a by-pass assembly is installed, shut the inlet valve o to prevent water ow through
the system. Otherwise, turn o main water inlet valve (and/or turn o the water pump).
Step 2: Disconnect power cord of UV system from electrical outlet.
Step 3: Release water pressure by opening a downstream faucet and then close the outlet
shut-o valve (if any). If there is no outlet shut-o valve, expect water to drain from the system
as the head pressure in the system will cause the water to ow back down.
Step 4: Remove the capve ground screw from the ground lug on the UV reactor.
Step 5: Remove the lamp connector from the reactor (gland nut) by pushing the lamp connec-
tor in and turning it ¼ turn counter-clockwise. Disconnect the lamp connector from the lamp.
CAUTION: the lamp may be hot!
Step 6: Being careful to touch only the ceramic ends, remove the lamp out of the reactor.
Step 7: Unscrew the gland nut from the reactor exposing the end of the quartz sleeve.
Step 8: Remove the quartz sleeve and o-ring by gently twisng and pulling the quartz sleeve.
Step 9: Using a so, lint-free cloth or towel wipe the sleeve down using a commercial scale
cleaner (i.e. CLR® or LIME-A-WAY®). This removes scaling or iron deposits that may be on the
outside of the quartz sleeve. Be careful not to get any moisture or liquids inside of the sleeve.
Step 10: Dry the sleeve with separate cloth.

13|Page
Step 11: Replace the o-ring and slide the sleeve back into the reactor following steps 7 and 8
from the installaon secon of the manual.
Cleaning the UV Sensor
Depending on the water quality, the UV sensor may require periodic cleaning. At a minimum,
the UV sensor should be cleaning on an annual basis. The following steps outline a basic clean-
ing procedure.
Step 1: If a by-pass assembly is installed, shut the inlet valve o to prevent water ow through
the system. Otherwise, turn o main water inlet valve (and/or turn o the water pump).
Step 2: Disconnect power cord of UV system from electrical outlet.
Step 3: Release water pressure by opening a downstream faucet and then close the outlet
shut-o valve (if any). If there is no outlet shut-o valve, expect water to drain from the system
as the head pressure in the system will cause the water to ow back down.
Step 4: Place something under the reactor to catch any water that may come out of the reac-
tor during the removal of the UV sensor.
Step 5: Unscrew (counterclockwise) sensor nut from the reactor and pull the sensor slowly out
of the sensor port.
Step 6: Holding the sensor in your hand wipe the at poron (sensor face) of the sensor with
isopropyl alcohol using a clean lint-free cloth.
Step 7: Replace sensor following step 9 from the installaon secon of the manual.
Operaon
Pulsar systems come with a feature laden controller that incorporates both the lamp driver (bal-
last) and control features in one water-ght case. Four main controllers are available for the
Pulsar systems (depending on your model). All four models feature a power factor corrected,
constant current lamp driver with a universal power input.
Please Note: While the LED or display screen is red and the buzzer is sounding the water from
the system should NOT be consumed. If any water does pass through the system during this
period, please follow the disinfecon procedure as outlined in this manual before the water is
consumed. For “100” series and “200” series systems, even though they have a visual and au-
dible warning built into the controller, a green LED or status screen does not necessarily indicate
that the water coming from this system is in fact potable (safe to drink). These systems do not
measure the level of disinfecon; they simply measure the “on-o” status of the lamp. Please
have your water checked for microbiological contaminants on a regular basis.

Simplisc in operaon, these systems feature a tri-color LED
that indicang system status and a 4-digit display to indicate
lamp life remaining. Pressing the buon will change the dis-
play to indicate total running me. When the UV lamp is on
and within its operang age, the LED will be green. When
the UV lamp is not on or the lamp life has expired, the LED
will be illuminated red and an audible buzzer will be sound-
ing. To remedy this condion, the UV lamp must be replaced
with a new genuine Pulsar UV lamp.

A full color LCD screen provides the user with a detailed de-
scripon of the system’s performance in addion to provid-
ing any applicable fault messages and system diagnoscs.
The controllers used in both the “200” Series and “300”
series are idencal. The dierence is that the “300” series
of products includes a UV intensity monitor. All “200” and
“300” series controllers include an “innite expandability
port” located on the right side of the controller. Simply plug
in an oponal UV sensor module into the expandability port
of a “200” series controller and the system will now monitor
the UV intensity of the system!
“200” & “300” Power-up Sequence
On start up, the controller will run through a diagnosc start-up and the sequence will be dis-
played as follows on the color LCD:
Next, the controller checks for and inializes any oponal modules that may be aached to the
system.

“300” Series Operaonal Screens
On systems with the UV monitor, the system will display the same screens as on the “200” series
except the UV Intensity replaces the home screen. The UV Intensity screen displays the level of
UV light detected by the sensor. UV intensity can be aected by poor water quality, scaling on
the quartz sleeve and/or sensor, lamp failure or lamp expiring. The following screens show the
UV Intensity dropping.
Below 56%, the numbers and warning sign turn red and an audible chirp is given by the ballast
every 15 seconds. Below 51%, the screen is solid red and a constant audible alarm is given. This
alternates with a screen indicang “water may be unsafe for consumpon”. With the solenoid
module, the controller de-acvates the solenoid valve, shung o all water ow.

“100” Series
At any point during this sequence, the audible chirp or alarm can be deferred for seven days by
holding the controller buon down for a period of ve seconds. The number of deferrals used
will be displayed as below. Once the deferral expires, the alarm will sound once again. The de-
ferral can be repeated up to three mes. PLEASE NOTE: At any point aer lamp expiraon, the
water may be unsafe for consumpon and should not be consumed without another form of
disinfecon.
Lamp Replacement (“100” Series Systems)
Aer the lamp is expired, it must be replaced with the same part number as indicated by the
label on the reactor. Begin replacing the lamp by unplugging the power for the controller, then
refer to Installaon, starng with step 11 (page 11) for instrucons on installing the new lamp.
To reset the mer in the controller, rmly hold down the buon on the controller for 10 seconds.
The controller will read “rSt3”, “rSt2”, “rSt1” and then beep. The buon can now be released, the
lamp countdown mer has been reset.
Lamp Replacement (“200” & “300” Series Systems)
Aer the lamp is expired, it must be replaced with the same part number as indicated on the
Maintenance Parts screen or on the label on the reactor. With the system powered down, re-
move and discard the lamp key from the controller. The replacement lamp is packaged with a
lamp key on the connector at the end of the lamp. Remove the key from the lamp and place it in
the controller. Refer to Installaon, starng with step 11 (page 11) for instrucons on installing
the new lamp.
QR Codes
A QR code (Quick Response code) is a matrix barcode rst designed for the
automove industry. Pulsar uses the QR code to store a link to a specic page
on our website. Users with a camera phone equipped with the correct reader
applicaon can scan the image of the QR code and over a wireless network
connect to a Pulsar web page in the phone’s browser. Pulsar’s QR webpage
has informaon on how to purchase replacement components as well as a
helpful video directory on system servicing (i.e. How to change a UV lamp
or quartz sleeve). To access the QR code on the Pulsar controller, press the
control buon unl the QR code screen appears.

System Troubleshoong
Hard Alarms: The following give a constant audible alarm. If present, the solenoid valve is closed,
and the 4-20, remote alarm and ethernet modules transmit the alarm.
System Display Problem Resoluon
The system has detected
a problem with the
lamp.
Reset lamp protecon circuit
-unplug unit for 10 seconds.
Replace the lamp with the
part as indicated on the
silver label on the reactor or
on the Maintenance parts
screen.
Although the lamp is
powered and visibly
illuminated, due to the
lamp’s age its UV output
is no longer sucient for
proper disinfecon.
Replace the lamp with the
part as indicated on the
silver label on the reactor or
on the Maintenance parts
screen.
Low UV Intensity.
Remove and clean the
quartz sleeve and sensor.
Check water quality meets
requirements on page 5 and
add ltraon as required.
Replace lamp.
Wrong lamp or sensor
installed.
Replace component with
proper model as indicated.
The UV sensor is no
longer communicang
with the system.
Ensure all modules are
connected properly to the
system and to each other.
Modules can be tested indi-
vidually by plugging in one at
a me and cycling power to
the system.
Replace any module that is
not detected when plugged
directly into the controller.
A bad connecon has
been detected in the IEP
port.
Missing or incorrect
lamp key.
Ensure the lamp key
(packed with the lamp, on
the connector) is installed.

Warning: Aer any hard alarm, the home or facility should be disinfected. Follow the steps un-
der the “System Disinfecon” heading.
Boil Water Advisory: If any failure occurs on a Pulsar UV system, the water
must not be used for human consumpon unl the system is returned to a
safe operaonal mode. If the water is used for human consumpon during this
period, the water must be boiled (minimum 20 minutes at a full boil) prior to
consumpon.

Temperature Management Devices
Your Pulsar UV system is designed to run connuously to ensure opmal disinfecon. However,
during periods when no water is drawn through the system, the energy from the disinfecon
process can cause the temperature of the water inside the chamber to rise. In extreme situaons
elevated water temperature or the uctuaon in temperature can lower the output of the UV
lamp. In these cases, or if the elevated water temperature is a nuisance, Pulsar recommends one
of the following forms of temperature management devices.
Cooling Fan
Designed for use on the Pulsar-HO systems, the fan runs connuously to cool the
water by forced convecon. The long-life fan is powered independently using a
compact modular power adapter that operates from 90-265V (47-63Hz). Order
PN 406-PUV-MD-FAN1 (only ts PUV-HO systems).
Temperature Relief Valve (TRV)
On reaching a higher temperature, the TRV is designed to drain a small amount
of water to allow fresh, cooler water to enter the system. The TRV works without
power and comes complete with 10’ of drain line. Order PN 130031 for 1/2”
ports, PN 130032 for 3/4” ports, PN 130033 for 1” ports and PN 130034 for 1
1/2” ports.
Expansion Modules
“200” and “300” series controllers incorporate an “Innite Expandability Port” (IEP) which al-
lows for expansion to the UV sensor and all other modules. Each module (including the sensor)
comes with both a male and female connecon. Connect any device to the controller and all
subsequent devices are then connected into the female end of last device added in a “daisy
chain” conguraon.
The following oponal expansion modules are available for use on “200” and “300” series UV
controllers. Contact your authorized distributor for purchasing informaon.
REMOTE ALARM CONNECTION MODULE: Al-
lows for a connecon to a remote device such as
a buzzer, light, alarm system, PLC, etc., via a pair
of contacts. In normal operaon the OK and COM
contacts will be connected, and in a fault condion
(Low UV, Lamp fail, Power Fail), the Fault and COM
contacts will be connected. Maximum Contact Rat-
ing is 1A-120V AC/DC (use 16-22 AWG). Order PN
406-PUV-MD-RAM.
