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

PAGE 11

As noted on page 5 General Installation Instructions, DO NOT SOAK KATALOX-LIGHT in water prior to start-up.  Do 
not plug the transformers into the receptacles 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 filter control valve 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. Also, now plug the transformer supplied with the Enhanced Oxidation Generator (EOG) into a 
120V uninterrupted receptacle and the male DC plug end into the female DC jack located at the back of the EOG.

•  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 filter control 

valve transformer so the filter 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:The Katalox-Light  mineral is dry, and filling to quickly with water will result in the mineral plugging the drain 
line and control valve assembly. 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 and when water is flowing steadily to drain, clear and without the presence of air, plug the 
control valve transformer into the receptacle to restore power. Display will again read 

BACKWASH 

and resume counting down. 

Momentarily press 

REGEN

 again. Display will read 

REGENERANT DRAW DN; 

allow this 30 minute cycle to complete.

 This 

allows a head of ozone to form inside the filter tank for the ozone over mineral filter to function properly. The factory installed 
Enhanced Oxidation Generator (EOG) is activated by the filter control valve’s programmed timing schedule...

EOG ON: Approx. 1 minute after the

 REGENERANT DRAW DN 

cycle begins - the EOG Green LED light will blink quickly 

(up to 3 seconds), then solid; CD cell producing ozone.
EOG OFF: Approx. 1 to 2 minutes before the REGENERANT DRAW DN cycle ends - the EOG Green LED light will blink 
slowly; unit is powered but in standby mode.

The EOG generator is an enhancement of the air over mineral filter; the controlled amount of ozone in the filter will increase the 
oxidation process while providing anti-microbial protection  against “nuisance” bacteria* slime buildup within the filter tank and 
the odors related to the buildup. The filter tank has an air blocker device installed inside the top dome that blocks ozone from 
re-entering the control valve body thereby reducing iron oxidation in the control valve and extending the valve’s service life. The 
filter control valve will automatically advance to the FILTERING position and the display will change color to SOLID BLUE. Place 
the bypass valve in the 

NORMAL OPERATION  MODE

 (

see figure 1 on page  4

).

Refer to the EOG ozone generator manual provided with 7-LXKATAIRO3 models for EOG operation, maintenance and trouble 
shooting instructions.

* Nuisance bacteria refers to iron and sulfate reducing bacteria which is harmless to human health.
