CHANGING THE MEMBRANE
TROUBLESHOOTING
Replacement TFC membranes come with complete changing instructions when ordered.
LEAKS
1) Filter sump: The O-ring in the sump may not be making firm contact, have dirt or hair on it or be stretched. Clean or
replace O-ring and tighten sump to make firm contact with cap.
2) Fitting Connection: Compression - Check that the fitting is tightened with all parts in proper place (refer to Fig. #8).
NO WATER OR SLOW FLOW
1) The system requires 2 hours from start-up to be fully charged and will take longer if it is hooked up to a refrigerator ice
maker.
2) The storage tank can hold up to 2.5 gallons and with heavy use can be depleted to zero. If this occurs, the system will
be fully charged in 2 hours and it becomes a recurring event an additional tank may be added, or a higher production
membrane may be needed.
3) Check colored tubing for correct connections.
4) Check the saddle valve at the water supply adapter is turned all the way counterclockwise for feed water and that
there is no restrictions along the green tubing.
5) Check for restrictions along the blue and yellow tubing and the storage tank ball valve handle should be parallel
(open) to the valve body.
6) Check the pre-filter, if it has a heavy dirt load it can restrict water flow to the system. Change sediment pre-filter
regularly.
7) If the storage tank is heavy with water and will not empty it has lost its air charge and needs to be serviced or
replaced. The air charge in the tank should be 5-7 psi with the tank empty of all water.
CUSTOMER SATISFACTION IS OF PRIMARY CONCERN, PLEASE CALL IN THE EVENT THERE
