Installation
Step 5. Cold Water Pipe Grounding
WARNING:
The house cold water pipe (metal only) is often used as a ground for the house electrical system.
The 3-valve bypass type of installation, shown in Figure 2, will maintain ground continuity. If you
use a plastic bypass valve at the unit, continuity is broken. To restore the ground, do the following.
Install a #4 copper wire across the removed section of main water pipe, securely clamping at both ends, see
Figure 9 (parts not included).
NOTE:
Check local plumbing and electrical codes for proper installation of the ground wire.

Step 6. Install Valve Drain Hose
NOTE:
See valve drain options on page 9.
1. Connect a length of 3/8” or 7/16” I.D. hose (check codes) to the valve drain elbow, on the controller, see Figure
4. Use a hose clamp to hold the hose in place. Route the hose out through the notch in the Faceplate Cover.
2. Run the hose to the floor drain, and as typically shown in Figure 2, tie or wire the end to a brick or other heavy
object. This will prevent ‘‘whipping’’ during regenerations. Be sure to provide a 4 cm minimum air gap, to
prevent possible sewer water backup.
NOTE:
In addition to a floor drain, you can use a laundry tub, or standpipe as a good drain point for this hose.
Avoid long drain hose runs, or elevating the hose more than 2.5 meters above the floor.
Step 7. Install Salt Storage Tank Overflow Hose
1. Connect a length of 3/8” I. D. hose to the salt storage tank overflow elbow and secure in place with a hose
clamp (see Figure 2).
2. Run the hose to the floor drain, or other suitable drain point no higher than the drain fitting on the salt storage
tank. (This is a gravity drain.) If the tank overfills with water, the excess water flows to the drain point.
NOTE:
Route the tubing neatly out of the way and cut it to the desired length.
DO NOT connect the valve drain tubing from step 6 to the salt storage tank over flow hose.
