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.

•   Press and hold the 

REGEN

 button for approximately 5 seconds until the motor starts.

•   Wait until display reads 

BACKWASH

 and numbers start counting down. (7-LXCTAIR and 7-LXIMAIR models will 

have an 

AIR RELEASE

 cycle for 5 seconds then 

BACKWASH

 will appear.)

If using optional bypass 

SLOWLY

 turn bypass valve to 

DIAGNOSTIC

 position (

See figure 3 on page 4

) or slowly open 

inlet valve to allow water to slowly enter filter.

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-LXCTAIR, 7-LXIMAIR MODELS-
Momentarily press 

REGEN

 again. Display will read REGENERANT DRAW DN; 

allow this cycle to complete

. This allows an 

air pocket to form for the filter to function properly. Control will automatically advance to the FILTERING position. Open the 

outlet valve of the filter, or if using optional bypass place to 

NORMAL OPERATION  MODE

 (

see figure 1 on page  4

).

FOR ALL OTHER FILTERS-
When water is flowing steadily to drain without the presence of air, momentarily press 

REGEN

 again. Display will read 

RINSE

. Open the outlet valve of the filter, or if using optional bypass place to 

NORMAL OPERATION  MODE

 (

see figure 

1 on page  4

). Allow control to finish the 

RINSE 

cycle. Allow the control to automatically advance to the 

FILTERING

 

position.

PLACING FILTER INTO SERVICE

GENERAL OPERATION

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 

 and 

  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.
