POSSIBLE CAUSES
REMEDY
PRESSURE DROP
• the sediment pre-filter is clogged
• replace filter cartridge with
appropriate five micron cartridge,
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 staining
problem
• the UV lamp is spent
• replace UV lamp
• change in feedwater quality
• have the source water tested to
ensure it is still within the allowable
parameters for use with this unit
• contamination after the disinfection
system
• it is imperative that the effluent
water stream be shocked with
chlorine after the water leaves the
disinfection system - the disinfection
system must have a bacteria free
distribution system to work
effectively
WARM PRODUCT
WATER
• common problem caused by
infrequent use
• 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 seals (on gland
nuts and/or sensor probe on
monitored units)
• ensure the o-ring is in place, check
for cuts or abrasions, clean o-ring,
moisten with water and re-install,
replace if necessary (Part# OR-212)
• condensation on reactor chamber
caused be excessive humidity
• check location of disinfection
system and control humidity
• inadequate inlet / outlet port
connections
• check thread connections, reseal
with Teflon™ tape and re-tighten
