INSTALLATION
STEP 5: Connect the Drain Line
If the drain line is a 5/8" flexible poly tube, slide the nut onto
the poly tube, then place the poly tube insert into the end of
the poly tube and tighten the nut on to the 3/4" drain line fit-
ting. The nut is only designed for use with flexible poly tube.
Use other nuts if attaching different materials. Run line to a
drain. Making sure you have a 1 1/2" airgap. You may use a
floor drain, standpipe or any open type drain (see Fig 10).
Do not use Vaseline, oils, or other unacceptable lubricants on
o-rings. A silicon lubricant may be used on the black o-ring.
Use a pliers or crescent wrench to tighten or unscrew the nut.
Do not use a pipe wrench to tighten or loosen nut. Do not use
pipe dope or other sealant on threads. Use Teflon tape on the
threads of the drain line control fitting when installing 3/4"
NPT or 1" straight fitting.
Figure 10: Also be sure drain line has an air gap.

STEP 5: Start-up
Place the bypass valve in the “bypass” position or mode
(see figures 12-14 below.)
Open the main water supply valve.
Open a couple of cold water faucets that are to be conditioned
and let run until air is expelled and pipes are full.
Open the outlet valve of the bypass.
Close the bypass valve.
Press and hold the regen button on the keypad for 3 seconds.
This will put the valve in manual mode. Now press the Regen
button twice.This will put the system in backwash. Slowly open the
inlet valve. (Open the valve a little at a time, pausing several times
to allow the unit to fill slowly and expel air.) When the tank has filled
and a steady flow to the drain is achieved, let the system run until
clear water can be seen coming from the drain line. When water is
clear press the regen button 4 times. This will take the valve back
to service position. Open several cold water and hot water faucets
and let run until hot water heater is full and cold water faucets have
expelled trapped air. Turn electrical power back on or re-light the
hot water heater. Now continue with control valve setup.

Start Up
1. Confirm that the bypass valve is in the bypass position (see im-
ages
9, 10 & 11 below)
2. Place the bypass valve in the “bypass” position or mode (see
figures 12-14 below.)
3. Open the user supplied feed water valve. Check for leaks and
repair as needed.
4. Open the outlet valve of the bypass.
5. Open a couple inside hot and cold faucets until all air has been
purged from the plumbing system. then close the faucets.
6. Initiate an Immediate Manual Regeneration by pressing and hold-
ing the “REGEN” button for 3 seconds. This will place the system
into “Backwash” mode, unplug the system from its electrical
outlet once it has cycled into the backwash position. This will stall
the unit in the “Backwash” mode so all air can be purged from
the tank.
7. Close the bypass valve.
8. Adjust the user supplied feed water valve to 1/4 open and place
the bypass valve into the “Service/Operating Mode” position.
9. Air will come out of the drain line until the backwashing tank is
completely purged of air. Then water will flow to drain. Allow
water to flow to drain for 15 minutes or until the water to drain is
clear of resin color throw.
10. Plug the system back into the electrical outlet and manually cycle
the control valve through the remaining regeneration steps by
pressing the “Next” button until it arrives in the Service position.
11. Check for system for leaks and repair as needed.
12. Installation is now complete and the system is ready for program-
ming.
