Installation

This DM-3 meter can be configured in a variety of different ways depending on your needs. Typically, the IN line is connected to the source water and the OUT line is connected to the product water.

1. Start by inserting the two sensors fully into the bottom of two T-fittings (sold separately).
2. Orient the sensor pins so that they are perpendicular to the direction of the T-fitting. The water should flow over both pins equally.
3. Disconnect the water source.
4. Snip the source water tube at a point between the source and the filter. Insert both ends of the tube into the top of the IN line sensor's T-fitting.
5. Snip the product water tube at a point between the filter and a dispenser. Insert both ends of the tube into the top of the OUT line sensor's T-fitting
6. The DM-3 meter can be attached anywhere on or near your pure water system using the included mounting bracket, which can be secured by screws or adhesive tape.
7. Reconnect the water source.

Now you are ready to start using your TDS meter!
