cleaning the unit
The exterior surfaces of the Aquafine UV unit should
be kept clean as part of routine maintenance. Use a soft
cloth with soap and water or any commercial stainless
steel cleaner. Avoid scratching the Lexan instrument
window.
LED status display panel
Monitor the Status Display LED Panel daily.
Immediately replace any failed UV lamp.
UV lamp replacement
Replace UV lamps after 8,000 hours of use.
THIS IS BASED ON NO MORE THAN 3 ON/OFF
POWER CYCLES PER 24 HR. PERIOD.
Please follow the operating requirements outlined in
the warranty section of this manual.
Premature lamp failure or lamp life deterioration can
be expected if the UV unit is cycled on/off more than
three (3) times a day. To replace the lamps, follow the
procedures on page 10.
The Colorguard™ ultraviolet lamps are rated for 8,000
hours of continuous use or 24 months of intermittent
use, whichever comes first. After this time, the lamp
glass will photochemically change and no longer allow
sufficient 254-nm shortwave UV, the germicidal ray of
the lamp, through the glass to effectively kill bacteria.
Failure to replace the ultraviolet lamps on a timely
basis of at least once every 8,000 hours may cause the
equipment to fail. With intermittent use, in no case
should the ultraviolet lamp be used for more than 24
months of operation without replacement, regardless of
the number of hours of operation, due to normal
operational degradation of the UV lamp.
CAUTION! Prior to remov-
ing the cover to access the
lamps and quartz sleeves,
you must release all pres-
sure to the UV treatment
chamber. Drain the cham-
ber if required. Do not stand in a direct
line with the end of the unit; observe
from the front or back of the unit.
quartz sleeve cleaning
& replacement
As water passes through the ultraviolet treatment unit,
minerals, debris and other substances in the water will
settle and deposit onto the quartz sleeve. This will
impair the ability of the ultraviolet rays to penetrate the
water.
If the water has been processed through deionization,
reverse osmosis, or distillation, the cleaning frequency
can be set at once per year. If clear, fresh water is used,
the probable cleaning frequency will be anywhere from
once every thirty days to once every six months. You
can determine this cleaning frequency. This is done by
visually inspecting any one quartz sleeve to see if any
debris or film has settle on the outside of the quartz
sleeve.
Recent studies have shown that degradation of the
quartz sleeve from continuous exposure to UV reduces
the amount of UV radiation transmitted into the water
stream. Based on these findings, we recommend the
annual replacement of the quartz sleeves in addition to
routine cleaning.
cleaning the quartz sleeves
Visually inspect a quartz sleeve thirty days after use to
see if any debris or film has settled on the outside. If
dirty, use the cleaning procedures that follow.
