8.4 UV STERILIZER MAINTENANCE
Follow the preventative maintenance procedures
to maximize the efficiency, reliable, and longevity
of the UV Sterilizer.
Refer to Table on Page 8-18 for recommended
maintenance schedule.
WARNING
! The most important
consideration is operator safety. The
following directly relates to operator
safety. All personnel must review and
comply with the following.
CAUTION ! Operators must observe
Safety Requirements at all times
Safety Requirements
The following safety requirements are mandatory.
Failure to comply can cause injuries and/or damages
to the UV unit.
1.
Never look directly at the blue ultraviolet lamp
when it’s “ON”. Never operate the ultraviolet
lamp outside the stainless steel cabinet. UV
light exposure can severely burn and damage
eyes and skin.
2. Properly ground the UV unit. Failure to properly
ground the UN unit can cause severe electrical
shock hazard.
3. Provide watertight piping and compression nut
seals. Failure to provide watertight seals can
cause damage to electrical components or cause
electrical shock hazard.
4. Disconnect power before servicing the UV unit.
The UV lamp and electrical components operate
with high voltage electrical power. Do not attempt
to service the UV unit without first disconnecting
the power source. Shut off the source of power
at the main panel breaker and use appropriate
tag-out or lock-out procedures to prevent
accidental power-up.
5. Only qualified service personnel should perform
services to the UV unit.
6. Remove pressure before servicing the UV unit.
7. Never operate the UV unit for more than 30
minutes without water flow. Elevated water
temperature can damage the UV unit.
8. Do not exceed 3 “Start/Stop” cycles per 24-hour
period. Exceeding 3 cycles will subjected the lamp
filament to excessive thermal stress leading to
premature failure of the UV lamp.
Unit Maintenance
The exterior surfaces of the UV unit should be kept clean
and dry. In most cases it may be necessary to clean the
exterior of the unit once a month. Use soft cloth and
soapy water, or any commercial stainless steel cleaner.
Interior of the ballast box should be inspected for debris.
Any debris should be removed using vacuum.
Quartz Sleeve
Debris and other matter in the water will settle onto
the quartz sleeve and eventually block the ultraviolet
rays from penetrating into the water. It is necessary to
determine a cleaning schedule for the quartz sleeve. The
frequency will depend on the specific type of water being
processed and the duty cycle of the unit.
Inspect the quartz sleeve 30 days after initial installation
to assess the amount of contamination collected over the
30-day period. Use the finding to determine a reasonable
schedule and frequency for periodic cleaning.
Clean-In-Place (CIP) cleaning is sometimes effective
in removing debris from the quartz sleeve. Conduct a
CIP cleaning test to determine its effectiveness. If CIP
cleaning is not effective, then a manual cleaning or
replacement is required.
When the quartz sleeve is due for cleaning, use the
following procedures.
1.
Turn off the water source to the UV unit.
2. Disconnect the power source to the UV unit.
3. Drain the UV treatment chamber.
4. Remove the ballast box cover.
5. Remove rubber boot and carefully pull out the UV
lamp through the compression nut pass-thru.
6. Use a channel lock to remove the compression nuts.
7. Remove the Quartz Sleeve carefully.
i) Screw the bowl on clockwise.
j) Hand snug to seal the O-Ring, do not use a
wrench or other tool to tighten, do not over
tighten. Over tightening causes stress to the
lid and bowl threads resulting in damage,
breakage, or cracks and subsequent
removal difficult.
