SYMPTOM
PROBABLE CAUSE
REMEDY
Lamp Cycling
Systems in which the UV is turned “ON“
and “OFF” frequently (more than 3X) will
cause lamp filament damages.
Electrical Power
Low equipment power will cause damage
to the electrical equipment. The electrical
power should be within 5% of the
nameplate voltage. Small transformers
may be required to boost low voltages.
Electrical Connection
Vibration can cause the electrical
connections to become loose. The
connections should be inspected and
repaired if damaged.
Heat
Excessive heat from “no flow conditions“
can damage the lamps.
Mechanical Vibration
Vibration from “water hammer”, pumps
and unsupported piping can cause excess
stress to the lamp filament and
equipment.
Compression Nut
Inspect the compression nut and O-ring to
insure that they are installed properly.
PREMATURE (LESS
THAN 9,000 HOURS)
LAMP FAILURE
Over Pressure
System pressure greater than the design
pressure will cause the sealing material to
fail.
Gasket Failure
The gasket and O-rings should be
inspected for deterioration. These
materials can be subjected to UV, ozone
and heat, which is damaging to the
material.
O-Rings
O-rings, which are not compressed
properly, will cause the quartz sleeves to
leak. Reinstall and replace the O-ring.
Sealing Material
O-ring and gasket material that are
damaged due to UV, ozone and physical
damage, will result in leaking. The
material should be changed.
“Water Hammer”
“Water hammer” pressure can be 5 -10X
higher than the static pressure of a water
system. “Water hammer” can cause
leaking and breakage to the quartz
sleeves.
Broken Quartz Sleeves
The ends of the sleeves should be
inspected for cracks and chips. Any
broken sleeves should be replaced.
LEAKING
Heat Damaged Part
If the unit is operating with compression
nuts manufactured with CPVC (gray
plastic) and has been exposed to elevated
temperatures, the compression nut may
be damaged. Excessive heat can distort
the plastic material, resulting in a loss in
compression of the O-ring seal. Change
compression nuts to stainless steel.
