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
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
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).
