diffi cult.
3. Ultraviolet Sterilizer Assembly: Maintenance of the
U.V. Sterilizer will consist of lamp replacement and
quartz sleeve cleaning. Replace the lamp at the
interval suggested on the Maintenance Timetable, or
if the lamp fails to start, whichever comes fi rst. The
lamp becomes progressively weaker over time, so
after six months of use, it may be ineffective though it
still lights.
CAUTION: Make sure that system power
is turned off before beginning sterilizer
maintenance.
4. Product water delivery pump fl ow control switch: This
switch is a normally open (N.O.) electrical switch and
the electrical contacts of the switch close when there
is product water fl ow in progress. The switch is set
for a minimum of 1/2 gallon per minute fl ow. Upon
closing, the switch sends a 24 VAC signal to a control
relay, which in turn operates the pump contactor
relay.
5. Product water delivery pump (type SC-100 SS):
Replace the ceramic seal approximately every 2000
hours, or at the fi rst sign of leakage.
CAUTION: Switch the system disconnect
switch to the “OFF” position, lock and tag the
switch for
maintenance. Close the system shut-off
valve.
A. Disassembly:
1. Remove 8 volume bolts from volume. Volume may be
left in piping.
2. Remove pump assembly with motor if possible.
Observe and make mental note of all parts prior to
any further disassembly.
3. Remove impeller locking screw and washer from
shaft.
4. Remove impeller from motor shaft by clamping down
on shaft with a 6” pair of “C” clamp vise grips. Place
“C” clamp vise grips through vented slots in bracket
and clamp down on shaft. Take a heavy screw driver
or fi le and wedge it between veins of impeller. Turn
counter clockwise and unscrew impeller from shaft.
Note: If “C” clamp is not available and Allen
wrench inserted in one of the pump shaft
setscrews can be used to keep shaft from
turning.
5. Remove spring and spring retainer of seal. Using two
screwdrivers wedged in seal at 180 degrees pry off
seal. Remove 4 motor bolts, remove base and slide
bracket over shaft. Pry ceramic seat from seal cavity
in bracket. Do not attempt to salvage seal or seat.
the pulley. A degree of “drag” must be left between
the pump and its frame to counteract the imbalance
caused by the drag from the pulley belt.
d. Move the pump forward only enough to provide
correct tension. Ensure that the motor pulley is still
aligned correctly, square to the pump pulley.
e. Carefully tighten the hold down bolts.
f. Recheck pulley alignment and if proper, replace the
pulley guard.
4. High-pressure pulsation dampener: The high-
pressure pulsation dampener is of the in line type
which has no moving or repairable parts.
7.6 POST FILTRATION SUBSYTEM
1. Salinity probe: The salinity probe will require cleaning
approximately once a year.
a. To clean the probe, disconnect the three electrical
salinity probe leads from the electrical controller
taking care to note which color goes on which
terminal.
b. Unscrew the probe from its tee housing (counter
clockwise).
c. Using a soft bristle brush scrub the monel probes to
remove any built up debris.
d. Reinstall the probe assembly into the tee housing and
reconnect the electrical wires.
2. Charcoal Filter: A sulfurous smell (like rotten eggs)
from the product water indicates that replacement
of the activated charcoal is necessary. If no such
smell develops beforehand, the charcoal should be
replaced monthly. The charcoal fi lter elements are
not cleanable. To replace the charcoal fi lter elements
proceed as follows:
a. Unscrew the bowl from each of the charcoal fi lter
housings (counter clockwise). Do not lose the lid
O-Ring.
b. Remove the old charcoal elements and discard them.
c. Clean the lid O-Ring with a cloth and apply silicon
based O-Ring lubricant.
d. Clean the bowl with a mild detergent and rinse it out
thoroughly.
e. Insert a new charcoal fi lter element, SRC CFE/20, into
each of the three charcoal fi lter bowls.
f. Place the lid O-Ring into the groove in the bowl.
g. Screw the bowl onto the lid clockwise, hand tight, and
slightly snug by hand.
CAUTION: Do not over tighten the bowl onto
the base. Over tightening will cause cracking
of the lid or bowl and will make removal
