Installation Instructions
For use on Refrigeration and/or Air Conditioning Systems ONLY
GENERAL – The See•All
®
Moisture &
Liquid Indicator may be installed any-
where in the liquid line. When located
between the Catch-All
®
Filter-Drier and
the expansion device, bubbles indicate a
shortage of refrigerant or a restriction in
the liquid line such as a plugged drier.
Change the drier when the color is in
the caution or wet range. When
received, the indicator may not indicate
dry. This in no way affects operation or
calibration of the indicator. The action
of the indicator element is complete-
ly reversible and will change color
whenever the moisture content of
the system changes.
The indicating element may change color
rapidly on some installations, while others
may take a much longer period of time.
New systems or systems where the drier
has been replaced will cause the indicator
to start changing color almost immediately.
However, it is recommended that the
equipment operate for 12 hours to allow
the system to reach equilibrium before
deciding if the drier should be changed.
The drying of the system should be con-
tinued until the indicating element stays
Dark Green.
The moisture change level of the refriger-
ant in Parts Per Million (PPM) for the
various See
•All Moisture Indicator colors
is shown below.
BRAZING INSTRUCTIONS – See
•All Moisture
& Liquid Indicators with 1/4” through
1-1/8” ODF connections are ready for braz-
ing as received. Avoid overheating the
body since extreme heat could damage
the glass joint. If a wet rag is used it
should be wrapped around the fittings
and bottom of the body, but not around
the top of the See
•All body. In this way,
any moisture inside the See
•All will not
condense on the cool glass surface and
wash away the color indicator material.
The indicator cartridge must be
removed from the SA-211, SA-213 and
SA-217 (1-3/8”, 1-5/8” and 2-1/8” line sizes)
See
•All indicators before brazing into the
liquid line. It is shipped hand tight.
All See
•All indicators with sweat fittings
are suitable for use with any of the com-
monly used brazing alloys including silver
solder, Sil-Fos, Phos-copper or Sta-Brite.
BRAZING TECHNIQUE –
1. Fittings are clean and ready to braze as
received. Avoid excessive polishing
with steel wool since this may rub off
the copper plating on models with plat-
ed steel fittings, making brazing more
difficult.
2. During brazing, bleed an inert gas (dry
nitrogen or CO
2
) through the tubing
and See•All.
3. Use a torch that is large enough to rap-
idly heat the line size being used.
