TOTAL DAYS OF OPERATION
The controller also displays the total running time of the controller. To obtain this reading, press the
push-button once. The total running time of the controller will be numerically displayed in days. This
information will remain displayed for ten seconds and will then revert back to the lamp life remaining
default screen. It should be noted that this value cannot be reset.
LAMP FAILURE (BLANK SCREEN)
When the system recognizes UV LAMP FAILURE (no current running through the lamp), the display
will be blank (no default UV LAMP LIFE REMAINING screen) and the system will sound an intermit-
tent audible tone (1 second on,1 second off). The system will remain in this state, until this condition
is remedied.
SYMPTOM
Sediment pre-filter clogged
Pressure Drop
Flow regulator
Quartz sleeve is stained or dirty
Change in feed water quality
Contamination in water lines after UV
High Bacteria counts
system
Possible break-through of sediment
through pre-filter
Common problem caused by
Heated Product water
infrequent use of water
Water Appears milky Caused by air in the water lines
Problem with O-ring seal (on retai-
ning nut and/or UV sensor)
Unit Leaking water Condensation on chamber caused by
excessive humidity & cold water
Inadequate inlet/outlet port connec-
tions
Interrupted controller
System Shutting down
intermittently
Loose connection between lamp and
connector
Lamp Failure Alarm
Moisture build up in connector may
on - New Lamp
keep lamp and connector from
making a solid connection
- Lamp life expired - countdown is at "0" days
LED display reads "A3"
- Press reset button for a deferred alarm, replace UV lamp
- Controller is in lamp failure mode
- Power system down, allowing it to reset itself; apply power in order to confirm that the controller is able
LED display is blank
to power lamp
- Check to see if there is sufficient power to the UV system

TROUBLESHOOTING
POSSIBLE CAUSES
DISPLAY FAULT MODES
SOLUTIONS
Replace filter cartridge with appropriate 5 micron cartridge.
Note: Check source water supply as fluctuations may occur in
source pressure.
Flow regulator will result in pressure drop when approaching full flow.
Clean sleeve with scale cleaner and eliminate source of staining
problem ie. soften hard water.
Have source water tested to ensure that water quality is still within
allowable limits for this system.
It is imperative that effluent water stream be shocked with chlorine
(bleach) before water leaves UV system - disinfection system must
have a bacterial free distribution system to work effectively.
Have source water tested for turbidity - may need stepped filtration
in order to catch all sediment entering water system (20 micron filter
followed by a 5 micron filter followed by UV system).
Run water until it returns to ambient temperature.
Run water until air is purged.
Ensure O-ring is in place, check for cuts or abrasions, clean O-ring,
moisten with water/ lubricant and re-install, replace if necessary
(410867).
Check location of disinfection system and control humidity.
Check thread connections, reseal with Teflon® tape and re-tighten.
Ensure system has been installed on its own circuit, as other equip-
ment may be drawing power away from UV (ie. pump or fridge).
• UV system should not be installed on a circuit which is incorporated
into a light switch.
Disconnect lamp from connector and reconnect, ensuring that a tight
fit is accomplished
Eliminate chance of any moisture getting to the connector and/or
lamp pins
