TROUBLESHOOTING GUIDE
Possible Causes
clogged
stained or dirty
quality
lines after UV system
of sediment through
pre-filter
caused by infrequent
use of water
water lines
seal (on gland nut
and/or UV sensor)
reactor chamber
caused by excessive
humidity & cold water
port connections
supply
between lamp and
connector
connector may keep
lamp and connector
form making a solid
connection
Solutions
• replace filter cartridge with appropriate 5
micron cartridge
Note: check source water supply as
fluctuations may occur in source pressure
• flow regulator will result in pressure drop
when approaching full flow
• clean sleeve with scale cleaner and
eliminate source of staining problem
(ie. soften hard water)
• have source water tested to ensure that
water quality is still within allowable limits for
this 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
• 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)
• run water until it return to ambient
temperature
• run water until air is purged
• ensure o-ring is in place, check for cuts or
abrasions, clean o-ring, moisten with water
and re-install, replace if necessary (OR-212)
• check location of disinfection system and
control humidity
• check thread connections, reseal with Teflon
tape and re-tighten
• 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
• disconnect lamp from connector and
reconnect, ensuring that a tight fit is
accomplished
• eliminate chance of any moisture getting to
the connector and/or lamp pins
