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 RMS 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 RMS 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 RMS UV disinfecon
system.

Assembly
The RMS rack-mount UV system is designed as a do-it-yourself (DIY) system with a single inlet
and outlet port. Unpack the system and ensure all the components are included in the box. Your
system is shipped with the following components:

7|Page
System Sizing
All RMS UV systems are rated for a specic ow rate in water that meets the quality parameters
on page 5. PLEASE NOTE increasing the ow above the system 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).
Figure 1. Typical Installaon

8|Page
PLEASE NOTE: All RMS 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 interrupter
(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).
Figure 2. System Orientaon (water inlet)

9|Page
Installaon
Step 1: Once both the orientaon and locaon have
been selected, securely fasten the rack to a suitable back-
ing. 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 fas-
tened 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 recommended so that the rated ow of your parcular RMS
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 packaging being careful not to touch the length
with your hands. The use of coon gloves is recommended for this pro-
cedure 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).
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 lter cartridges in their appropriate housings. For the RMS branded prod-
ucts, please refer to the RMS Rack-Mount UV System Specicaon chart. 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 car-
tridge 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).
Figure 3. Lamp Removal Spacing

Figure 5. Cartridge Removal
Step 9: Install the UV sensor (RMS-S 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 sen-
sor 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.
Figure 6. UV Sensor Installaon Figure 7. IEP Connecon
Step 10: The system 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 system. 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. To help vent the pressure from the system while the system is lling up with water, it is a
good idea to twist open the pressure relief valve located on the top of the lter head. Close the
valve once water appears at the port. If the system has two lters, perform this funcon on the
housing closest to the water inlet rst and then on the next lter in sequence.
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.

11|Page
Step 12: Install the lamp key into the controller (RMS5 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 9).
Step 13: Plug the lamp connector into the lamp. Note the keying for proper alignment (see Fig-
ure 8a, 8b). 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 10.
Figure 9. Lamp Key Installaon Figure 10. LUMI-Loc™ Connector
Step 14: Tighten the capve ground screw to the ground lug on the UV reactor to ensure proper
grounding.
Figure 11. 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.
Note: Installaon of your RMS disinfecon systems shall comply
with applicable provincial/state & local regulaons.

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 minimum 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 RMS 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 LUMI-loc
connector 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
RMS 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 RMS
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 RMS4 & RMS5 systems, even though they have a visual and audible 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-colour
LED that indicang system status and a 4-digit display to in-
dicate lamp life remaining. Pressing the buon will change
the display 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
sounding. To remedy this condion, the UV lamp must be
replaced with a new genuine RMS UV lamp.
RMS5/RMS5-C Controllers

A full colour LCD screen provides the user with a detailed
descripon of the system’s performance in addion to pro-
viding any applicable fault messages and system diagnoscs.
The controllers used in both the RMS5 and RMS5 are iden-
cal. The dierence is that the RMS6series of products in-
cludes a UV intensity monitor. All RMS5 RMS5-C 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 RMS controller and
the system will now monitor the UV intensity of the system!
RMS5/RMS5-C 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 colour LCD:
Next, the controller checks for and inializes any oponal modules that may be aached to the

RMS5/RMS5-C Operaonal Screens
On systems with the UV monitor, the system will display the same screens as on the RMS 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.

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 (RMS4/RMS4-C 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 lamp countdown mer is then
reset.
Lamp Replacement (RMS5/RMS5-C 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. RMS 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 RMS web page in the phone’s browser. RMS’s QR webpage has
informaon on how to purchase replacement components as well as a help-
ful video directory on system servicing (i.e. How to change a UV lamp or

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
to 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.
Unplug and reinstall the key.
Ensure the key part number
matches Lamp on Mainte-
nance Parts screen.

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 RMS 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 RMS RMS 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, RMS recommends one
of the following forms of temperature management devices.
Cooling Fan
Designed for use on the RMS-C 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 MOD-FAN-RMS (only ts “-C” variants and RMS-20 series).
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 RMS-TRV-1 for 1”
ports.

Expansion Modules
All controllers (with the excepon of the “-E” variants), incorporate an “Innite Expandability
Port” (IEP) which allows 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 RMS 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
MOD-RAM-RMS.
SOLENOID CONNECTION MODULE: Connects a
NORMALLY CLOSED line voltage solenoid valve to
the system. On a non-monitored system, the sole-
noid will only close on a lamp failure error. On a
monitored system, the solenoid is closed when the
UV level drops below 50%. Also note that in cases
where emergency use of untreated water is re-
quired, the controller can be placed into a manual
override mode allowing for the ow of water in an
alarm condion. Order PN MOD-SOL1-RMS.
4-20 mA MODULE: Outputs a 4-20mA signal of the
UV output to a remote device such as a data logger
or computer. Order PN MOD-420-RMS.
ETHERNET MODULE: Allows for all controller func-
ons to be connected to a computer via an Ether-
net cable.
