1. The above picture shows the installation of a typical disinfection system and the related components that may be
used for the installation. The use of a by-pass assembly is recommended in case the system requires "off-line"
maintenance. If this is the case, it must be noted that the system will require supplementary disinfection of the
distribution system if any water is used during this by-pass condition. In addition, during by-pass, the water will NOT
be disinfected. Please refer to the complete disinfection procedure as outlined on page 8 of this document. If the
water is to be consumed while the system is off-line, the water must be boiled for twenty minutes prior to consumption.
2. Select a suitable location for the disinfection system and its related components. As it is recommended to install a
ground fault protected circuit (GFCI), make sure that this is taken into consideration prior to any installation. The
system can either be installed vertically( inlet port at the bottom), or horizontally, however the vertical installation is
the most preferred method. When selecting a mounting location, you must also leave enough space to allow for the
removal of the UV lamp and/or quartz sleeve (minimum clearance equal to disinfection system overall length; refer to
dimensions page).
3. Install the quartz sleeve as outlined on page 9.
4. Mount the system to the wall using the supplied clamps. Various connection methods can be used to connect the
water source to the system, however union type connectors are recommended. The use of a flow restrictor device is
strongly recommended when installing your system in order to maintain the manufacturer's rated flow rate. The flow
restrictor should be installed on the outlet port and is designed to be installed in one direction only. Ensure that the
flow of the water matches the flow direction as indicated on the flow restrictor. DO NOT SOLDER CONNECTIONS
WHILE ATTACHED TO THE SYSTEM AS THIS COULD DAMAGE THE O-RING SEALS.
5. Mount the electronic ballast controller horizontally to the wall, near the UV reactor chamber. Ideally place the controller
above the reactor and away from any water connection point, to prevent any water from potentially leaking onto the
controller by means of a leak at a connection point or a "sweating" system. Make sure you allow for a "drip-loop" on
the lamp power cord, again to prevent any water from potentially entering the controller. A ground stud and nut are
provided on the UV reactor chamber. Attach the supplied 3 foot long, #14 AWG green ground wire to this ground stud
using the ring terminal end. Attach the fork teminal end of the ground wire to the electronic ballast controller ground
screw.
6. Install the UV lamp as outlined on page 9.
7. When all plumbing connections are made, slowly turn on the water supply and check for leaks. The most likely cause
for leaks is from the o-ring seal. In case of leak, shut water off, drain chamber, remove the gland nut assembly, wipe
the o-ring and threads clean and re-install. Refer to exploded view diagram page.
8. Once it is determined that there are no leaks, plug the system into the GFCI, and check electronic ballast controller
to ensure the system is operating properly. The controller is designed to detect both power to the system and lamp
illumination. It is important to NEVER LOOK DIRECTLY AT THE GLOWING UV LAMP.
9. Allow the water to run for a few minutes to clear any air or dust that may be in the UV chamber.
PLEASE NOTE: When there is no flow, the water in the chamber will become warm, as the UV lamp
is always on. To remedy this, run a cold water tap anywhere in the house for a minute to flush out the
warm water.
