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.
8. Wash the Quartz Sleeve with mild soapy
water and rinse in clean hot water.
If dirt remains after rinsing, the quartz sleeve
should be replaced. Contact your local CSR to
order a replacement.
NOTE
! Failure to perform quartz sleeve
maintenance may reduce the efficiency of
the UV light to adequately treat water in
the treatment chamber.
Checking for Leaks : Visual inspect the UV unit
exterior for signs of leakage. The cause of any
leakage must be located and repaired.
If a leakage is detected, perform the following.
