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

As noted on page 5 General Installation Instructions, allow lighter weight mineral such as Carbon and Filter Ag
to soak in water prior to start-up; recommend minimum 12 hours up to 24 hours for best results. 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.
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 and Filter Ag should not be backwashed immediately for extended
periods of time. For best results, 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.
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
OPERATION MODE (see figure 1 on page 4). Allow filter control valve to finish the RINSE cycle and automatically
advance to the FILTERING position.
