PLACING UNIT INTO SERVICE: Make sure inlet and outlet valves are to their closed positions. Turn on main water
supply. Open a cold water faucet. This will clear the lines of any debris (solder, pipe dope, etc.) that may be in the line. Let
water run at tap for a couple of minutes, or until clear. Turn off faucet.
• Carbon should be soaked in water for at least one hour before backwashing at full-flow. The mineral is dry
and filling too quickly will result in the mineral plugging the drain line and valve assembly.
• Press and hold the ▲ and ▼ buttons. Advance to the BACKWASH position by pressing and releasing the ▲ button.
• Slowly turn the bypass valve to the DIAGNOSTIC MODE (Figure 2) to allow water to
slowly enter the system. The
mineral is dry and filling too quickly will result in the mineral plugging the drain line and valve assembly.
• Unplug the control valve to keep the valve in the backwash position.
• Flow water to drain very slowly, gradually increasing the flow until water runs clear. This may take up to 30 minutes.
• Plug in the control valve.
• Advance the control to the SERVICE position by pressing and releasing the REGEN button.
• Place the bypass valve in the NORMAL OPERATION position. (Figure 3)
• It is common to have some very fine particles visible in the service line immediately after loading new mineral even
after initial backwash. This is temporary and will clear up after a few gallons of water have passed through the filter.
A sediment cartridge filter can be installed after a backwashing filter to capture these particles if their presence is
objectionable.
