Do not plug the transformer into the receptacle yet. Make sure inlet and outlet valves are to their closed positions. If using
optional bypass, place in bypass position. Turn on main water supply. Open a cold water faucet. This will clear the line
of any debris (solder, pipe dope, etc.) that may be in the line. Let water run at faucet for a couple minutes, or until clear.
Turn off faucet. Now plug the transformer into a 120 volt receptacle (be certain the receptacle is uninterrupted). Within 5
seconds the control display and buttons will illuminate and the time of day screen will appear.

Mineral is dry, and filling to quickly with water will result in the mineral plugging the drain line and valve
assembly. Some minerals such as carbon and Filter Ag should not be backwashed immediately for extended
periods of time. These minerals need to soak in water for a 24-hour period before backwashing at full flow. Flow
water to drain very slowly, increasing the flow until the water runs clear.
FOR 7-LX125CTAIR, 7-LX125IMAIR MODELS-

User Displays
When the system is in normal service mode, one of up to four available User Displays will be shown. Pressing
NEXT
will
alternate between the following displays:
• Current time of day
• Treated water flow rate
• Service contact name and phone number (if entered)
• Remaining days to regeneration (if Day Override is
programmed)
To clear the Service Call reminder
, press the

buttons simultaneously while the number and banner text
screen is displayed.
If the system has called for a backwash that will occur at the preset time of backwash, the words REGEN TODAY will
alternate with the header on the display.
Utilizing the control valve’s built-in water meter, a water drop flashes on the display when water is being treated (i.e. water
is flowing through the system).
Note: As an energy saving feature, the control will automatically turn off all SOLID BLUE or SOLID GREEN
display illumination and keypad illumination after about 5 minutes of the last keypad button push. Any further
keypad touch will cause the re-illumination of the display and keypad, and re-activate keypad control.
