UV LIGHT MAINTENANCE
Follow the preventative maintenance procedures to maximize the efficiency, reliable, and longevity of the UV unit.
Refer to Table 1 Periodic Maintenance Table 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.
