MANUAL DIAGNOSTICS

Use the following procedures to advance the unit through the regeneration cycles to check operation.

• Press and hold the (Set / Clear) button for 3 seconds until 18:88 shows in the display.

• Press the (Recharge Day) button to display the position switch open or closed indicator.
• The letter P and a dash or dashes indicate position switch operation. The letter shows if the switch is closed. A dash shows when the switch is open.

NOTE: The position switch is closed when the plunger is depressed, open when extended.

CORRECT SWITCH DISPLAYS	VALVE CYCLE STATUS
- -	Valve in soft water, backwash or fast rinse position.
- P	Valve rotating from one position to another.

To enter FILL cycle, press and hold the (VAC/RCHG) button for 3 seconds to start the motor.

• If the motor does not run, check the motor and all wiring connections.
• Check for fill water flow to the salt storage tank. If water does not enter the tank, look for an, obstructed nozzle and venturi fill flow plug or brine tubing.

After verifying fill, press the (VAC/RCHG) button to move the valve into brining (if the DOUBLE BACKWASH option is set, the valve will enter backwash and fast rinse before brining). A slow flow of water to the drain will begin. Verify brine draw from the brine tank by shining the flashlight into the brinewell and observing a noticeable drop in the liquid level after several minutes. Remove brine lline from the nozzle and venturi by loosening the ferrule nut. Place a finger on the nozzle and venturi opening and feel for suction.

NOTE: Be sure water is in contact with the salt, and not seperated by a salt bridge.

• If the unit does not draw brine, check for (most likely to least likely):
• Dirty or defective nozzle and venturi.
• Nozzle and venturi not seated on the gasket, or gasket defective.
• Restriction in valve drain, causing a back-pressure (bends, kinks, elevated too high, etc.).
• Obstruction in brine valve or brine tubing.
• Inner valve failure (obstructed outlet disc, wave washer defective, etc.).

Again press the (VAC/RCHG) button to move the valve into backwash. Look for a fast flow of water from the drain hose.

If flow is slow, check for a plugged drain hose, backwash flow plug or top distributor.

• Press the (VAC/RCHG) button to move the valve into fast rinse position. Again, look for a fast flow of water from the drain hose. Allow the unit to rinse for several minutes to flush out any brine that may remain from the brining cycle test.
• To return the valve to soft water position, press the (VAC/RCHG) button once again.
• Press the (Recharge Day) button to display 18:88.
• Press the (Set / Clear) button to return the present time.
