Troubleshooting
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 infre-
quent 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 connec-
tions
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.
Loose connection between UV lamp
and connector
Disconnect UV lamp from connector and reconnect, ensuring that a tight fit is accom-
plished
UV lamp Failure Alarm
on - New lamp
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.
Press reset button for a deferred alarm, replace UV lamp
LED display is blank
Controller is in UV lamp failure mode.
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 UV lamp
