TROUBLESHOOTING GUIDE
Symptom
Possible Causes
Solutions
Pressure Drop
Sediment pre-filter
clogged
• Service pre-filtration
Note:
check source water supply as
fluctuations may occur in source pressure
High Bacteria
Counts
Quartz sleeves are
stained or dirty
• clean sleeves with scale cleaner and
eliminate source of staining problem (ie.
soften hard water, see page 8)
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
• shock with chlorine (bleach) downstream of
U\V system - disinfection system must have
a bacterial free distribution system to work
effectively (see page 6)
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 system)
Heated
Product Water
Common problem
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
Unit Leaking
Water
Problem with o-ring
seal (on gland 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
reactor chamber
caused by excessive
humidity & cold water
• check location of disinfection system and
control humidity
Inadequate inlet/outlet
port connections
• Ensure flange seals are correct and not
deteriorated. Clean and re-install. If leaks
persist, replace flanges/seals
System
Shutting Down
Intermittently
Interrupted power
supply
• ensure system has been installed on its own
circuit, as other equipment may be drawing
power away from UV
Lamp failure
alarm is on
(blank display)
Loose connection
between lamps and
connectors
• disconnect lamps from connector and
reconnect, ensuring that a tight fit is
accomplished
Moisture build up in
connectors may keep
lamp and connectors
from making a solid
connection
• eliminate chance of any moisture getting to
the connectors and/or lamp pins
