Section 6 Troubleshooting
Green LED indicates UV lamp “ON”.
Symptom Possible Causes Solutions
Pressure Drop
Sediment pre-filter clogged
Replace filter cartridge with appropriate 5 micron cartridge.
Note: Check source water supply as fluctuations may occur in source pressure.
Flow regulator Flow regulator will result in pressure drop when approaching full flow.
High Bacteria
Counts
Quartz sleeve is stained or dirty
Clean sleeve with scale cleaner and eliminate source of staining problem (ie. soften hard water,
refer to
Section 4.2 .
Change in feed water quality
Have source water tested to ensure that water quality is still within allowable limits for this
system.
Contamination in water lines after UV
system (eg. power failures, plumbing Disinfection system must have a bacterial free distribution system to work effectively. Refer to
Section 3.2
Possible break-through of sediment
through pre-filter 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
Heated Product
Water Common problem caused by infrequent
use of water
Run water until it returns to ambient temperature.
Water Appears
Milky
Caused by air in the water lines Run water until air is purged.
Unit Leaking Water
Problem with O-ring seal (on retaining
nut and/or UV sensor) 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).
Condensation on UV chamber caused
by excessive humidity & cold water
Check location of disinfection system and control humidity.
Inadequate inlet/outlet port connections Check thread connections, reseal with Teflon
®
tape and re-tighten.
System Shutting
Down Intermittently
Interrupted controller
• Ensure system has been installed on its own circuit, as other equipment 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.
UV lamp Failure
Alarm on - New
lamp
Loose connection between UV lamp
and connector
Disconnect UV lamp from connector and reconnect, ensuring that a tight fit is accomplished
Moisture build up in connector may
keep UV lamp and connector from
making a solid connection
Eliminate chance of any moisture getting to the connector and/or lamp pins
DISPLAY FAULT MODES
LED display reads “A3”
• UV lamp life expired - countdown is at “0” days. Refer to Section 5.1.2 , Understanding your A3 Code.
• Press reset button for a deferred alarm, replace UV lamp
LED display is blank
• Controller is in UV lamp failure mode. Refer to Section 5.1.5 , UV Lamp Failure. Replace UV Lamp, refer to Section 4.1 .
• Power system down, allowing it to reset itself; apply power in order to confirm that the controller is able to power UV lamp
• Check to see if there is sufficient power to the UV system
Green LED off (12 VDC
only)
• UV lamp failure. Replace UV Lamp, refer to Section 4.1 .
• No input voltage to controller
