Quartz Sleeves Maintenance:
As water passes through the UV treatment unit, minerals, debris and other matter
in the water will settle and deposit onto the quartz sleeves. This will impair the
ability of the ultraviolet rays to penetrate into the water. Therefore, it is imperative
to determine a cleaning schedule for the quartz sleeves. The frequency will
depend on the specific type of water being processed, i.e. its turbidity, its flow
rate, and on the duty cycle, i.e. 24 hour continuous or intermittent at planned or
random intervals. Replacement of the quartz sleeves should be completed every 2
years of operation.
For replacing, follow the installation procedure on page 16.
Inspect the quartz sleeves one month after the first installation for a good
indication of the degree of contamination you can expect over subsequent longer
periods. Then you will be able to determine a reasonable time schedule for
periodic cleaning.
If the water has been conditioned through deionization, reverse osmosis or
distillation, the cleaning frequency can be set at once per year. If clear, fresh
water is used, the cleaning frequency should be anywhere from once every thirty
days to once every six months. With super clean water, this can even be
extended further. Determine cleaning frequency by visually inspecting any one
quartz sleeve to see how much debris or film has settled on the outside of it.
Clean In Place (CIP) cleaning is sometimes effective in the removal of debris from
the sleeves. A test should be completed to determine the effectiveness of a CIP
cleaning. After a chemical CIP has been completed, the quartz sleeves should be
visually inspected for the removal of material. If CIP cleaning is not effective, then
a manual cleaning or replacement of the sleeves will be required
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 following procedures.
Should this be insufficient, they should be replaced.
To place an order,
please contact your local Aquafine
®
representative or call customer service.
1. Turn off the water to the unit.
2. Disconnect the electrical circuit.
3. Drain the UV Treatment Chamber.
4. Remove the socket cover.
5. Wear clean gloves to prevent contamination of the quartz sleeves and
UV lamps.
6. Remove the retainer caps and lamp sockets.
7. Remove the UV lamps from inside the quartz sleeves.
8. Using the appropriate compression nut tool, loosen the compression
nuts and carefully remove the quartz sleeves.
9. Wash the quartz sleeves with mild soap and water. Rinse in clean, hot
water.
10. The Detector window should be cleaned during quartz sleeve
cleaning and maintenance.
See page 35.
NOTE:
Failure to perform quartz sleeve cleaning maintenance may cause inadequate UV treatment
and low sensor values. The quartz sleeves maintenance is very important to the overall operation of
the equipment. If the quartz sleeves are not properly maintained, the UV efficiency will be reduced.
