Maintenance, Continued
Cleaning the quartz sleeve, headpiece, & O-Ring
The quartz sleeve must be kept clean to kill bacteria effectively. Your water
quality and mineral content will determine cleaning frequency. Perform a
visual inspection after thirty (30) days of operation. If the sleeve is dirty,
shorten cleaning intervals. If the sleeve is clean, lengthen cleaning intervals.
At this time, clean the headpiece and O-Ring also.
Step Action
1 Fill bucket or other receptacle with warm, soapy water.
2 Follow Steps 1 through 5 for replacing the lamp (see previous page).
3 Unscrew the headpiece and carefully remove the quartz sleeve from the disinfection chamber.
IMPORTANT! The quartz sleeve may stick to the headpiece. Be sure to hold both pieces
carefully so they don’t separate during removal.
3 Take the headpiece and O-ring off the quartz sleeve. Clean the headpiece, O-Ring, and quartz
sleeve with a mild soap and hot water solution. If the sleeve is still not clean, use a mild acid
(citric acid or Lime-Away), then rinse with hot water.
4 Push the O-Ring a few inches down on the quartz sleeve and lower the sleeve into the
chamber.
5 Screw the headpiece onto the disinfection chamber to secure the quartz sleeve and O-Ring in
place.
6 Carefully reinstall the UV lamp and the Glo-Cap (see directions for installing the UV lamp).

Replacing the O-Ring
Sanitizing the system
General maintenance for the O-Ring requires that you replace it every 365 days. If,
however, during routine cleaning of the quartz sleeve, you find the O-Ring cut,
damaged, or extremely dirty, then it should be replaced at this time. To replace the
O-Ring, follow the directions for cleaning.
Before initial use of your UV unit and after routine maintenance procedures, you
should sanitize your water system to ensure that no organisms are present.
Step Action
1 Pour household bleach into your water system. If you have a filter container, fill it
with bleach. If you have no filters then introduce chlorine directly into your well.
The amount of chlorine depends upon the diameter and depth of your well.
(Generally, use ½ gallon to treat an 8” diameter/80’ deep well and one gallon for
anything larger.) You may contact your State Extension Service or a water
treatment specialist for additional information.
2 Open hot and cold water taps throughout the house and let the water run until you
detect a chlorine odor. To ensure that the hot water heater is also purged, allow
the hot water to run until the water becomes cold.
3 Turn off the taps and allow the water to stay in the pipeline for about six hours or
overnight but not more than 36 hours to avoid corrosion.
4 Open hot and cold water taps throughout the house and let the water run until the
chlorine odor disappears.

performance
Power fails
Display screen is blank
Unit gives faulty alarms
You miss the 5 second
window for resetting unit
The troubleshooting guide gives you suggestions for resolving problems.
• Ensure that the headpiece is tight.
• Verify that inlet water pressure is not >125 psi.
• Ensure that headpiece O-ring is seated properly.
• Lubricate O-ring (use food-grade silicone).
• Check O-ring for cracks or rips. Replace if necessary.
• Check quartz sleeve for possible cracks. If sleeve is cracked, call distributor for
replacement.
• Verify that all electrical connections are correct.
• Replace lamp. If problem is solved, resume unit operation.
• If lamp still does not light, electrical control box may need to be replaced. Call distributor
for replacement information.
• Replace lamp if it is more than 365 days old or nearing the end of its lamp life.
• Perform routine maintenance.
• Check water quality. If water quality has changed then you may need to install filters or
other disinfection units to ensure that water supply does not exceed recommended
maximum concentration levels (shown in Step 1 of Pre-Installation Instructions).
• Verify flow rate using the flow rate table found in the Technical Specifications at the back
of the manual.
• The unit will restart automatically and the internal Days counter will be the same as before
the power failure. If the unit has an optional solenoid valve installed, the valve will open 5
minutes after power is restored to the unit.
• Upon restart if unit stays in alarm disconnect the power for 30 seconds. Restart the unit
by pressing the reset button within 5 seconds.
Note: The unit is designed for continuous operation. Never connect the unit to a timer or other
device, which will cause the unit to cycle on and off. Excessive cycling of the power will
reduce lamp life.
• Ensure that the unit is assembled and installed correctly. In the case of improper handling
or assembly during installation and/or servicing, the unit will turn off power to the lamp
and display a blank screen.
• Check for damage to the lamp filament elements, quartz sleeve, or electrode connectors.
Applying power to a unit with such damage will cause a blank display screen. Damage
may be caused from shipping, overheating the lamp by operating the unit with no water in
the chamber, introducing debris into the unit from the water source, or improper handling
or assembly during service or installation.
Note: Units with the optional solenoid valve installed will turn off. In most cases, replacing
the lamp, and/or quartz sleeve will return the unit to proper operation. If the unit fails to
resume operation, notify your distributor.
• The ballast or control circuit may be faulty. Call distributor for replacement information.
• If you miss the 5 seconds allotted to reset the unit, it may not calibrate properly.
Disconnect the power for 30 seconds. Then supply power and restart the unit by pressing
the RESET button within 5 seconds.
