The UV rack system has been designed to be installed on the cold water line only.
NOTE: The UV System should remain on continuously to ensure protection of your water system. During normal operation of the
system, the green power LED will be illuminated. And a glow will appear through the VuCap®. When there is no flow in the system, the
water in the Greenway® UV disinfection chamber will be warmed by the UV lamp. Running a cold water tap for about 30 seconds will
eliminate all of the warm water.
The presence of small air bubbles in the water system may occasionally give tap water a milky appearance, but air bubbles will not affect
water quality or taste. Initially, filtered water may appear cloudy due to the release of air trapped within the filters and throughout the system.
Dependant upon your use of the system, this condition should disappear within a few days to a few weeks following system installation.
Always perform the following start-up procedure when starting your UV rack system for the rst
time or after a dormant period:
1. Shut off the main water supply valve.
2. Mount the UV rack system to the wall. Please note that due to the weight of the UV rack, it is essential that the unit is mounted
directly to a concrete wall (screws and washers not provided) or directly into framing studs (screws and washers provided).
Do not mount the unit directly on dry wall.
3. Check to be sure that the O-ring(s) are on the filter housing(s). It may have dropped into the housing during transportation of
package. Lubricate the O-ring with water and place on housing. Place the filter(s) into the housing(s) and mount the housing(s)
to the filter head. Use the wrench supplied to tighten the filter housing(s). The double filter housing models GAUVR10-20S,
GAUVR10-20H and GUVR10-20S the 10” 5 micron filter and housings is always mounted on the right side (when facing the
front of mini rack) of UV rack. Then the 20” 5 micron carbon block filter and housing are mounted on the left side.
4. The filters are wrapped and the wrapping around the filter(s) has to be removed. Mount the filter(s) and housing(s) on the UV
rack system.
5. Hook up inlet water connections and the outlet water connection. For ease of installation and service it is recommended using
union couplings on both the inlet and outlet lines.
6. Confirm that all of the plumbing connections are secured. Partially open the main supply valve while releasing air from the
system by opening a downstream faucet.
7. Plug in the Greenway® UV disinfection system and confirm that the UV lamp is illuminated; (purple glow through the VuCap®.
8. If no leaks are visible at low flow, then fully open the main supply valve. Check for leaks.
9. For chlorine disinfection of household water distribution system, follow procedures outlined in section 3.3.
10. Open a downstream tap and flush the system for 15 minutes prior to initial use.
11. Your UV rack system is now ready for use.
The following instructions have been provided to assist with general maintenance of the system; UV lamp replacement and quartz sleeve
cleaning/replacement. All other system repairs must be completed by an accredited service technician.
Your UV rack uses a dual treatment process involving both filtration and an optical system to disinfect water using ultraviolet light. The
water filters, quartz tube and UV lamp require regularly scheduled replacement / service in order for the UV rack to provide maximum
performance.
The UV lamp has an approximate life of 9000 hrs. (one year of continuous use). Replacement UV lamps and quartz sleeves are available
from an authorized dealer. Use only Greenway® UV lamps and sleeves to ensure maximum system performance.
Replacement UV lamp and quartz sleeve can be found on page 8 (section 5.5) of this manual.
Your Greenway® UV disinfection system in equipped with a visible/audible UV lamp failure indicator. In the event of a failure of the UV
lamp, the red LED light will flash and a loud beeping will be audible from the electronic ballast of the unit. Please note that if these conditions
occur and you are on a non-municipal supplied water source, you should immediately stop using the water for potable applications until the
UV lamp is replaced and disinfection of the distribution lines is completed.
