Troubleshooting
Symptom
Possible Causes
Solutions
Pressure Drop
Sediment pre-filter clogged
Replace filter cartridge and refer to
Section 2
.
Note: Check source water supply as fluctuations may occur in source pressure.
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. due to a power failure,
plumbing dead ends, etc.)
Refer to
Section 3.2
, Disinfection Procedure to disinfect your system.
Possible break-through of sediment
through pre-filter
Test source water 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).
Heated Product
Water
Common concern caused by
infrequent use of water
Run water until it returns to ambient temperature.
Install temperature management valve.
Water Appears
Milky
Caused by air in the water lines
Run water until air is purged.
Chamber Leaking
Water
Problem with O-ring seal (on retaining
nut)
Ensure O-ring is in place, check for cuts or abrasions, clean O-ring, moisten with water/ lubricant
and re-install, replace if necessary (Refer to
Section 2
for part number).
Condensation on 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.
Lamp Failure
Alarm on - New
UV Lamp
Loose connection between lamp and
connector
Disconnect the 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”
•
Lamp life expired - countdown is at “0” days
•
Press reset button for a deferred alarm, replace UV lamp (refer to
Section 4.1
).
LED display is blank
•
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 to power lamp
•
Check to see if there is sufficient power to the UV system
