4. Push the tubing through the nut until it bottoms out in the elbow.
5. Remove the adapter nut, then install the o-ring on the tubing. Do not
push the backup or metal grab rings back on the tubing when
installing the o-ring on the tubing.
6. Install the adapter nut on the elbow and hand-tighten the nut.
Install a cartridge in the holder as follows:
1. Install the large o-ring (part no. 06419) on the cartridge holder. A
small o-ring should be on the bottom of the cell. The large o-ring is
packaged separately during shipment.
2. Install the fresh cartridge in an upright position, the large opening
toward the bottom. The lower tightening wheel should be turned
down to allow the cartridge to be centered between the top and
bottom o-ring.
3. Turn the lower tightening wheel until the cartridge seats against the
top o-ring.
Caution Do not apply a wrench to the nut - the nut should be hand-
tightened only enough to prevent leakage.
Caution Do not over-tighten the tightening wheel.
Note Water purified by the ion-exchange method is not necessarily free
from odor and color. In some instances, color or odor could be introduced
by trace quantities of free amines or low molecular weight polymers which
are present in fresh untreated resin. Generally, the amine odor lessens or
disappears after passing a few gallons of water through the holder.
