INSTALLATION AND OPERATING INSTRUCTIONS

MODEL AD-1400 MONOBED DEMINERALIZER

Maximum operating pressure: 125 PSI

Maximum operating temperature: 90 degrees F

The AD-1400 Demineralizer will work with either bulk resin (#RR-1400) or the resin cartridges

(#NGDI-20). The resin refill or the resin cartridges are not supplied with the basic unit and must
be ordered separately and loaded into the unit prior to use.

The system consists of the blue filter housing assembly with a tapped head, a 200,000 Ohm test
light, mounting bracket, 2 wall mounting screws, 2 hose elbow fittings (3/4” NPT x 3/8” hose
barb), and a distribution tube assembly.

INSTALLATION

The unit must be installed with a shutoff valve on the inlet to facilitate the changing of the
exhausted resin. Locate the unit in a place where it will be convenient to service, allowing at least
6” below the unit to remove the housing sump.

Install the test light into the hole on the top of the black filter cap. Please be sure to use ptfe
tape to prevent water leakage.

The mounting bracket should be securely fastened to the wall for support with the 2 mounting
screws. Attach the black filter head to the wall bracket with two 3/8th hose barb connectors. Use

ptfe tape on the threaded side of the connectors to prevent leaks.

Run either plastic tubing or rigid plastic piping to the inlet supply to the inlet side of the filter cap.
Run either plastic or rigid plastic piping from the outlet side of the filter cap to the supply source.

The plumbing line must be able to withstand the full line pressure of the supply feed.

LOADING BULK RESIN

After the unit is completely installed, turn on the water supply to check for leaks. When satisfied
that there are no leaks, turn off the inlet valve and open the out let valve to relieve the pressure in
the unit. Grasp the housing and turn counter-clockwise to loosen and remove the sump. Remove
the housing carefully so as not to damage the distributor tube inside the unit. The o-ring may lift
out of the grove or stick to the cap; it should be free of debris and re-installed in the grove.

Before loading, make sure the bottom strainer of the distributor tube is inserted into the socket at
the bottom of the sump.

Carefully pour in the resin from one jar into the sump; the distributor should be installed in the
sump at this time. After loading, clean the threads, and the o-ring to be sure there is no resin
present. If the resin beads are not properly cleaned off, a leak may occur. Screw the housing onto

the cap until tight. Do not over tighten-should be hand tightened only.

LOADING RESIN CARTRIDGE

After checking for leaks, grasp the housing and turn counter-clockwise to loosen and remove the

sump. Remove the center distributor tube inside the sump; this part is only needed for the bulk
resin. Install the resin cartridge into the sump with the larger black cap up. Re-install the sump
onto the cap until tight. Do not over tighten-should be hand tightened only.

IMPORTANT: DO NOT DISTURB the RED plug located inside the top cap of the

cartridge. It will damage the cartridge and renter it unusable.

PLACING UNIT INTO SERVICE

Plug the electrical cord from the test light into a wall outlet. Slowly open the inlet water supply
until water flows freely out of the faucet and the air is purged from the unit. The conductivity
light will turn on and your unit is now ready to provide high quality water.

WHEN TO CHANGE BULK RESIN OR CARTRIDGE

When the conductivity light goes out with water running, this is an indication the quality of

the water has dropped below 200,000 Ohms (above 5 microhos). You will need to replace either
your bulk resin or the resin cartridge. Follow the above procedures to replace the resin in your
current unit. The exhausted resin can be disposed of into any waste container, as there is no
danger or any hazard.

TEST LIGHT

The unit should be monitored while the water sample is flowing to obtain the greatest accuracy.
In sensitive applications it is recommended that the unit be periodically cleaned and tested for
accuracy with a standard solution of known resistivity equivalent to the specified threshold value.
The electrodes should appear clean; shiny; free of deposits and microbiological growth.

THIS MONITORING DEVICE SHOULD NOT BE USED AS THE PRIMARY
INDICATOR FOR CRITICAL OR MEDICAL APPLICATIONS.
