sealing tape to the threads. Screw the Product

High Pressure Gauge
[31]: If the pressure
gauge fails to register, the orifice may be
corroded with debris. Use a thin wire to
dislodge debris trapped in the orifice.
15. Back Pressure Regulator [33]: The Back
Pressure Regulator Stem does not require
maintenance. Should the O-Rings need
replacement, remove the control manifold
from the end of the Membrane Vessel
Assembly. Carefully unscrew the High
Pressure Gauge [31] and remove the cover.
Remove the Flow Meter to access the Back
Pressure Regulator shaft. Use customary
care when replacing the O-Rings on the Back
Pressure Regulator shaft.
16. Flow Meter [34 & 42]: Since the flow meter
body is clear, light penetrates it and supports
biological growth. To clean the flow meter
body, remove the top access fitting, the guide
rod, float and O-Ring bumpers and tube
stops. Clean the interior of the tube using a
bottlebrush, soft rag, cotton swab or other soft
item. Reassemble the unit.
17.
Salinity Probe
[41]: The salinity probe requires
cleaning once a year. To clean the probe,
unscrew the probe from its tee housing. Using
a soft bristle brush, scrub the probes to remove
any built up debris. Remove all old Teflon
tape from the male pipe threads of the Salinity
Probe and clean the threads before reinstalling
hand tight only.
18.
Charcoal Filter
[44]: A sulfurous (rotten
egg) smell from the product water requires
the replacement of the Charcoal Element.
Otherwise, the Charcoal Element should
be replaced every 3 to 4 months. It is not
cleanable.
To replace the element, unscrew the blue bowl
counter clockwise by hand. Avoid spilling
the product water from the bowl. Remove the
Charcoal Filter Element from the bowl and
discard. Remove the O-Ring from the bowl and
take care to not damage it. Clean the bowl with
a mild detergent and rinse out thoroughly.
Wipe the O-Ring with a damp cloth and
lubricate it sparingly with O-Ring lubricant
and reinstall. Rinse a new HRO CFE Charcoal
Filter Element with fresh water to remove the
carbon fines from the Element. Insert it into
the bowl. Screw the bowl on clockwise. Hand-
tighten only enough to seat the O-Ring.
CAUTION
: If the O-Ring is missing, not
properly seated, or if the bowl is over
tightened, leaks develop.
19.
Controller
[56]: The salinity controller does
not require any routine maintenance.
20.
UV Ultraviolet Sterilizer
[45]: Follow the
preventative maintenance procedures to
maximize the efficiency, reliable, and longevity
of the UV Sterilizer.
* Refer to Table on Page 8-20 for recommended
