Maintenance
acid container. It is important to handle the quartz sleeve
with care to prevent breakage. Make certain that all finger
prints are wiped clean before reinstalling (see installation of
the quartz sleeve). Replace O-Ring [ATS8-544(1)] every
time a quartz sleeve is cleaned or replaced. We recommend
replacing the quartz sleeve once a year.
U.V. LAMPS:
INSTALLATION OF THE ULTRAVIOLET LAMPS:
**DO NOT PUT POWER ON AT THIS TIME!**
CAUTION: Never operate or look directly at U.V. lamp
outside the disinfection chamber.
Make sure unit is unplugged when installing or servicing
ultraviolet lamp. Remove any paper tabs on the U.V. lamp
and avoid allowing fingerprints and other debris to deposit.
Carefully place the lamp inside the quartz sleeve leaving
enough space to connect the socket connector to the lamp
pins. Then gently slide the brass dust cap over the end nut,
securing the lamp and protecting it from dust.
ULTRAVIOLET LAMP MAINTENANCE
REQUIREMENTS:
The U.V. lamp is rated for 9,000 hours of continuous use.
After this period of time, the U.V. lamp has undergone a
photochemical change. While the lamp will not normally
be burned out, the lamp quartz may no longer emit the
254-nm shortwave U.V. to effectively kill bacteria. Failure
to replace the U.V. lamps every 9,000 hours may cause
bacteriological breakthrough. Should the use of the
disinfection unit be intermittent, in no case should the
U.V. lamp be used for more than 24 months regardless of
the number of hours of operation due to normal shelf life
degradation of the U.V. bulb. Changing the quartz sleeve
should be done at the same time U.V. lamp replacement is
scheduled.
It is recommended that your water supply be tested
periodically (yearly) through your local health department or
approved certified laboratory.
ELECTRICAL:
The GDS series are furnished with 6’ line cord that will plug
into a 120V outlet. Electrical receptacles must be properly
grounded for safe operation. Improper grounding will void
any warranty.
When possible use a separate breaker to minimize voltage
fluctuations and avoid accidental shut off. After unit is
installed and water is turned on, plug the unit into 120V wall
receptacle. View lamp operation through safety Sight Port
lens. NOTE: Avoid exposing your eyes to U.V. light.
QUARTZ SLEEVE:
Installation of the Quartz Sleeve:
Always handle quartz sleeves carefully to prevent breaking
or chipping. The quartz sleeves are to be clean and free of
fingerprints before installing.
After unplugging the unit, remove the brass dust cap and
electrical connection. Then remove brass end nut. Install
the quartz sleeve through the stainless steel threaded nipple
until it is centered in the quartz spring. Use a small amount
of plumber’s grease and install the O-ring around the quartz
sleeve. Avoid riding the O-Ring on any threaded part of the
nipple. Hand-tighten the brass end-nut to form a compression
seal around the quartz sleeve. Avoid over tightening the nut,
which may cause a fracture on the end of the quartz sleeve.
Under normal operation conditions, hand-tightening will
provide a 100 psi seal. Do not use any devices to tighten end
nut.
After you have tightened the brass end nut and all other
plumbing connections, open the outlet valve. Slowly open
the inlet valve and flush out all remaining air. Then close
the outlet valve and slowly open the inlet valve fully. Check
the unit for leaks. If you find a leak at the brass end-nut,
tighten the brass end-nut further. If the leak continues, drain
the unit and inspect the quartz O-Ring and quartz sleeve for
proper seal. Once you complete checking the unit, reassemble
O-Ring and tighten brass end-nut. Repressurize the unit and
check again.
REQUIREMENTS FOR CLEANING THE QUARTZ
SLEEVE:
As water passes through the U.V., minerals, debris and other
matter in the water may deposit onto the quartz sleeve. After
sufficient film has formed on the quartz sleeve, the ability of
the ultraviolet germicidal rays to pass though the quartz sleeve
and into the water may be impaired. Therefore, it is necessary
to determine a cleaning schedule for the quartz sleeve. The
frequency will depend on the specific type of water conditions.
If the water has been processed through deionization, reverse
osmosis, or is distilled, cleaning may be required only once per
year. If untreated water is used, the cleaning frequency will
vary. A minimum of once yearly is standard recommendation
for cleaning and lamp replacement. Contact your local dealer
for scheduling this service. Your specific situation will vary the
frequency time according to the water quality of the home or
facility application.
QUARTZ SLEEVE CLEANING PROCEDURES:
To clean the quartz sleeve, turn off the water flow to the
disinfection unit, turn power off, and at a separate faucet or
valve relieve the water pressure from the UV. Then disconnect
the electrical service to the lamp pins. Carefully remove the
U.V. lamp. Loosen the end nut with O-Ring and remove the
quartz sleeve. The quartz sleeve may then be washed with a
mild soap and hot water solution and rinsed clean with hot
water. Should this be insufficient to clean the quartz sleeve,
a mild acid may be used (i.e. vinegar). Be certain to follow
all recommended safety and handling procedures on the
