Before You Begin
The following will be needed for installing the UV system:
Tools
•Pipecutter,hacksaworotherspecializedtoolsrequiredtocutintoyourexisting
plumbing (e.g. if you have PEX piping)
•Solderingtools(torch,ux,emeryclothandsolderasrequired
- depending on plumbing.)
•Wrench(fortighteningttings)
Other Materials
• Inlet/outlet connections
•Teon™threadtape
Water Quality Parameters
UV disinfection is extremely effective 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 disinfection.
Treated water should be tested for at least the parameters listed below. If the
water exceeds the listed parameters Davey strongly recommends that appropriate
pretreatment equipment be installed (equipment required will depend on parameters
being treated):
Hardness: <120mg/L (7gpgUS) – if hardness level is 120mg/L (7 gpg)
  orslightlybelowthequartzsleevemustbecleaned 
  periodicallyinordertoensureefcientUVpenetration;if
above the water must be softened.
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 (transmittance): 85% (Please contact Davey if water has a UVT that is
less than 80% for pre-treatment recommendations)
You can have your water tested via your local dealer or a private analytical laboratory.
Itisalwaysrecommendedtoinstallpre-ltrationofatleast5microns(1micron
preferred for Cyst removal on Rain Water) prior to a Microlene Aquashield Centurion
UV disinfection system.

Location
Choose a location where the main cold water line is accessible. The system must
be installed after other water treatment equipment (i.e. softener), but before any
branches (See Figure 1).
Figure 1. Typical Installation
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InstallationFigure3).The
controller will require a Residual Current Device (RCD) outlet and should be mounted
beside or above the chamber.
IMPORTANT:
All Microlene Aquashield Centurion UV Disinfection Systems are intended to be
installed under a weather proof cover and should not be exposed to the elements.
MCS-C Weather proof cover (purchased separately)
• Protects the chamber and controller from rain and direct elements
• Enables the 3 Stage UV system to be set up left to right or right to left for ease of
installation.
• Mounting holes are aligned with the UV System
• Insert locking pin or screwdriver to lock
cover open during servicing
• Lamp change through side of the cover
holes, no disassembling required
• Made from: 1.2mm zinc-
titaniumlaminatezintek®
•Powdercoatedwithmattsatinblacknish

Orientation
This system has the ambidextrous capability of being able to have the main water
inlet enter from either the left hand side or right hand side of the unit. The unit comes
pre plumbed from the factory for a left hand water inlet.
To change to a right hand water inlet follow these simple steps (See Figure 2):
Step 1: Removethetwoblackltersumphousingsfromthelterheadandsetaside.
Step 2: Removethelterheadscrewsfromthetopmountingplate.
Step 3: Carefullylowerthelterhead(orheads)fromtherackassemblyandrotate
180 degrees. Reassemble onto the rack assembly and take note of the
arrowslocatedonthetopofthelterheadsindicatingwaterow(whichnow
shouldbeindicatingaowdirectionofright-to-left).
Figure 2. System Orientation (water inlet)
Step 4: Remove the stainless steel UV chamber from the two plastic clamps located
on the top of the rack. Carefully remove the top straps securing the chamber
with the aid of a standard (slot) screwdriver. Rotate the chamber 180 degrees
(with the inlet now facing to the left and the lamp connections located towards
theright)andplacebackintothecellclampsandreafxthetwotopstraps.
 Ineithertheleftorrightcongurations,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).
IMPORTANT:
All Microlene Aquashield Centurion UV Disinfection Systems are intended to be
installed under a weather proof cover and should not be exposed to the elements.

Installation
Step 1: Once both the orientation and location have been
selected, securely fasten the rack to a suitable
backing. As the rack system is extremely heavy
whenlledwithwater,itisimperativethatthe
rack be mounted with suitable fasteners for the
particular installation. Mounting to a plasterboard
backing is not suitable, unless the rack is
fastened directly to the wall studs.
Step 2: The use of a bypass 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particularMicrolene
systemisnotexceeded.Theowrestrictorshouldbeinstalledontheinlet
port of the chamber.
Step 4: It is recommended to have a licensed plumber connect the UV chamber 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
connections based on your particular plumbing requirements. The inlet port
ofthelterhousingisa1”FNPTconnectionandtheoutletportoftheUV
chamberisa1”MNPTconnection.
 TheseNPTthreadswillconnecttothesamesizeBSPthreadsonplastic
pipettings,alternativelyNPTtoBSPadaptersfromyour
local plumbing store can be used.
Step 6: Once the system has been plumbed in, gently remove the
quartzsleevefromitspackagingbeingcarefulnottotouch
the sleeve or lamp with your hands. The use of cotton
gloves is recommended for this procedure as oils from the
hands can leave residue on the sleeve and lamp which can
ultimately block the UV light from getting to the water.
Carefully slide the sleeve into the chamber until you can
feel it hit the opposite end of the chamber. Align the sleeve
so it is centered along the length of the chamber, then gently push it in to lock
it into the internal centering springs in the far side of the chamber. CAUTION:
Pushing too hard when the sleeve is not aligned can damage the centering
springs. Slide the o-ring onto the sleeve until it is butted up against the
chamber (See Figure 4).
Step 7: Handtightentheprovidedglandnutoverthequartzsleeveontothethreaded
endofthechamber.Ithasapositivestoptopreventovertightening.Arm
force may be required to fully tighten 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.Refertothe
specicationchartinthedatasheetorthisinstructionmanual.PLEASE
NOTE: This chart indicates the correct cartridge position for the default
“left-hand”orientationwiththewaterinletlocatedontheleftsideofthe

rack system. If the orientation was switched, the cartridge 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 5. Cartridge Removal
Step 9: Install the UV sensor (optional and only compatible with the MCXS
system, not compatible on the MCS standard controller).Aligntheat
portion so it faces the gland nut end and matches up with the half metal lip
on the sensor port (see Figure 6). Insert the sensor so it is fully seated and
hand tighten 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.
