excessive vibration and warping which will damage the
quartz sleeve.
5Operational Guidelines
a) Release the pressure in the UV treatment chamber
before breaking the compression nut seals.
b) Disconnect all power to the UV unit before servicing.
c) Do not allow the inlet water temperature to drop
below 35ºF (2ºC).
d) Do not allow the flow rate to exceed 2 GPM.
e) Do not cycle the UV unit more than 3 “ON/OFF”
cycles in a 24-hour period.
f) Ensure all plumbing connections are tightly sealed
before applying pressure.
g) Before connecting the return tube, flush the unit to
rinse out any debris left from the installation process.
WARNING! UV LIGHT EXPOSURE CAN SEVERELY
BURN AND DAMAGE EYES AND SKIN.
WARNING! DO NOT look at the blue UV light. DO
NOT operate the UV lamp outside of the UV treatment
chamber.
CAUTION! The unit operates on high voltage and
must be serviced by qualified personnel only.
CAUTION! Standard flow rate are based on water
temperature 35ºF to 100ºF. If the inlet water
temperature exceeds 100ºF (38ºC), please contact
your local CSR.
CAUTION! Cycling more than 3 cycles will reduce
the end-of-life (EOL) output and/or cause premature
lamp failure.
6Preventative Maintenance
Follow the preventative maintenance procedures to
maximize the efficiency, reliable, and longevity of the UV
unit.
Refer to Table 2 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
6.1 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.
6.2 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.
6.2.1 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
