Lancaster 7-LXDAN-1B, Installation, Operating And Service Manual

PAGE 9

As noted on page 5 General Installation Instructions, allow lighter weight mineral such as Carbon to soak in 
water prior to start-up; recommend minimum 12 hours up to 24 hours for best results. DO NOT SOAK KATALOX-
LIGHT. Do not plug the transformer into the receptacle yet.

 Rotate the bypass handles to the

 BYPASS

 position (see 

figure 2 on page 4). Turn on main water supply. Open a cold water faucet. This will clear the line of any debris 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. The display will change color, from 

SOLID BLUE to SOLID GREEN.

•  The display will first read

 AIR RELEASE

 and count down 1 second.

•  The display will now read 

FILTERING

 and count down 1 minute.

•  The control valve will repeat this sequence two more times.

•  Wait until display reads 

BACKWASH

, the motor stops running, and numbers start counting down. Unplug the 

transformer so the filter control valve will not cycle to the next position. 

SLOWLY

 turn bypass valve to 

DIAGNOSTIC

 position (

see figure 3 on page 4

) to allow water to slowly enter filter in order 

to expel air.

CAUTION:

If mineral is dry, filling to quickly with water will result in the mineral plugging the drain line and control valve 

assembly. Some minerals such as Carbon should not be backwashed immediately for extended periods of time. 

For best results, soak Carbon 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.

CAUTION:
DO NOT SOAK KATALOX-LIGHT. Water pH increment might be observed with newly installed Katalox-Light 

(which eventually will stabilize to the inlet water pH with time). To prevent pH increment, allow the filter to 

backwash Katalox-Light for at least 60 minutes.

After at least an hour has passed (if using katalox-light) and when water is flowing steadily to drain, clear and without the 
presence of air, plug the transformer into the receptacle to restore power. Momentarily press 

REGEN

 again. Display will read 

REGENERANT DRAW DN; 

allow this 30 minute cycle to complete.

 This allows a head of air to form inside the filter 

tank for the air over mineral filter to function properly. The filter tank has an air blocker device installed inside the top dome 
that blocks air from re-entering the control valve body thereby reducing iron oxidation in the control valve and extending 
the valves service life. The filter control valve will automatically advance to the FILTERING position and the display will 
change color, from SOLID GREEN to SOLID BLUE. Place the bypass valve in the 

NORMAL OPERATION  MODE

 (

see 

figure 1 on page  4

).
