P. INSTALLATION TROUBLESHOOTING
Problem: Leak at the feed water tapping valve.
Cause: Tapping valve is not clamped tightly enough.
Solution: Tighten the tapping valve clamp screws evenly and firmly keeping both halves of the bracket parallel. Be sure not to deform tubing.
Problem: Leak at the drain saddle.
Cause: Drain saddle not clamped tightly enough.
Solution: Tighten the drain saddle screws evenly and firmly.
Problem: Leak at the fittings threaded connection.
Cause: Fitting is improperly taped or not tightened sufficiently.
Solution: Retape the threaded portion with Teflon® tape and thread it in firmly. Do not over tighten.
Problem: Leak at the fitting's push-in connection.
Cause: Tubing is defective if there is a tubing misassembly.
Solution: Remove the tubing. Squarely cut off 1/4 inch from the end of the tubing using a sharp razor knife and reinsert it into the fitting. Make sure that the tubing is pushed in completely until it seats.
Problem: Leak at the filter cartridge head.
Cause: Defective or misaligned
Solution: Close the feed water tapping valve and the storage tank valve. Lift up on the faucet handle and drain the tank a minimum of 5 minutes. Remove the filter cartridge and check the condition of the
Problem: The faucet leaks from the spout with the handle down.
Cause: An obstructed or defective valve seat in the faucet mechanism.
Solution: Remove the faucet spout with a twisting/lifting motion and slide the faucet handle forward over the spout hole to gain access to the faucet valve. Unscrew the
Problem: No steady drip from the open faucet after the tank is drained.
Causes:
•The feed water tapping valve is not open.
•The feed water tapping valve is not installed properly.
•A leak from any product water fitting connection.
•The icemaker valve was left open before the
•Air is still trapped in the system.
Solutions:
•Open the feed water tapping valve completely.
•Check the feed water tapping valve installation to make sure that the needle has pierced the tubing.
•Correct the fitting leak as outlined above.
•Close the icemaker valve and wait until the faucet drips.
•Wait for the air to be purged from the system.
Problem: Water leaks from air gap module opening. Causes:
•The drain line tubing is looped, kinked, or has a low spot.
•The drain line is blocked or the drain hole is not drilled through completely.
•Air is locked in the air gap outlet.
•There is excessive RO reject flow.
Solutions:
•Trim any excess tubing to obtain a short,
•Check to see that the drain line is clear of any obstruction and remove the drain saddle fitting to verify that the hole is drilled through completely.
•Blow air into the air gap outlet using a short length of tubing.
•Disconnect the red SFC reject tubing from the faucet air gap inlet tubing and check the reject flow rate. It should be less than 175 ml/min. If it is greater than 175 ml/min., replace the red SFC reject tubing with the new one of proper length.
Problem: Too little or no reject flow.
Causes:
•Red SFC reject tubing is plugged or defective.
•The feed water tapping valve is not open.
•An obstruction in the faucet air gap module.
Solutions:
•Replace the SFC reject tubing with one of proper length.
•Open the feed water tapping valve completely.
•Remove the air gap module and inspect the internal flow path. Replace the air gap module if necessary.
Problem: Chlorine or other unpleasant taste/odor is evident after the initial tank filling.
Cause: Residual preservative/sanitizer is still in the water.
Solution: Drain and fill the storage tank several times if necessary.
Problem: Noise in the drain (gurgling or dribbling sound).
Cause: The reject water is dripping into the standing water in the drain trap.
Solutions:
•Make sure that the 3/8" black drain tubing from the faucet air gap module slopes continuously downward to the drain saddle without any loops or low spots.
•Angle the drain piping so that the reject water runs down the side of the drain pipe.
•Change the location of the drain saddle to the horizontal drain pipe or any alternate vertical drain pipe which is farther from the trap. Properly plug the original hole. Caution: Make sure the drain saddle is always installed above (before) the trap.
