Kits of preformed 1/4" or 3/8" tubing are available as a sep-

arate item at a nominal cost; application instructions and a

detailed template are included. The kits can be used with

either SAE Flare or ODF Solder type See•Alls.

REPLACEMENT INDICATOR PAPER — Sporlan kit K-SA-4

consisting of a slotted cylinder and indicator paper assem-

bly is available for replacing the indicator in the fused glass

style Sporlan See•Alls (1/4" thru 1-1/8" sizes). Replacement

is through the bottom (see Figure 1). If the indicator

becomes damaged, it is generally recommended that the

entire See•All be replaced. However

, the parts kit can be

used in situations where it is difficult to remove the

See•All.

removal of the cartridge from the brass saddle adaptor before

brazing. The cartridge is shipped hand tight for easy removal.

The See•All may be installed anywhere in the the liquid

line, but preferably after the Catch-All Filter-Drier and

ahead of the metering device.

The indicator element of the See•All prior to installation

will be yellow, indicating a wet condition. This is a normal

situation since the air in contact with the element is above

0.5% Relative Humidity. This does not affect the operation

or calibration of the See•All. As soon as it is installed in a

system, the indicator element will begin to change according

to the moisture content of the refrigerant. Some change may

take place rapidly at the start-up of a new system or after

replacement of a drier on existing installations. In some

cases the See•All will change in as short a time as 15 min-

utes. However, it is

recommended that the equipment

operate for about 12 hours

to allow the moisture in the sys-

tem and the See•All color to come to complete equilibrium.

The action of the indicator element is completely reversible

and will change color as often as the moisture content of the

system varies.

The drying of the system should be continued until the indi-

cating element changes from chartreuse to green. The actu-

al moisture content of the refrigerant will be in accordance

with the above table.

For best results with the nickel plated SAE flare fittings

that are used on See•Alls,

lubr

icat

e the flare surface

and

the back of the flare nut with refrigerant grade oil during

assembly. This is particularly necessary to avoid leaks if the

See•All is being assembled to another plated steel flare fit

ting, such as the Catch-All Filter

-Drier

On systems having liquid lines larger than 2-1/8'' O.D., the

See•All should be installed in a bypass line. During the oper-

ating cycle this will provide sufficient flow to obtain a

satis-

factory reading for both moisture and liquid indication.

Best results will be obtained if the bypass line is parallel to

the main liquid line and the take off and return tubes pro-

ject into the main liquid line at a 45° angle.

While satisfactory liquid and moisture indication will

generally be obtained in any position, the preferred methods

of installation are shown in Figure 2.
