Troubleshooting:
TRoUBLESHooTING GUIDE
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, 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
• 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 (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 return 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 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
(OR-212)
Condensation on
reactor 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 Shut-
ting Down
Intermittently
Interrupted power
supply
• 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 Lamp
Loose connection
between lamp and
connector
• disconnect lamp from connector and
reconnect, ensuring that a tight fit is
accomplished
Moisture build up in
connector may keep
lamp and connector
from making a solid
connection
• eliminate chance of any moisture getting to
the connector and/or lamp pins
