Preliminary Note: The Wash can be open for this Procedure.
Items needed: TDS Meter Part # P-WAT-2836
Procedure:
- Run the Spot Free Rinse for a minimum of 5 minutes to ensure that fresh water from the RO Purified Water Tank is used and to allow the membranes to Stabilize.
- Using the cap from the TDS Meter, fill the cap with Water from the Spot Free Rinse arch. If the reading is less than 20 ppm, the system is functioning as it should. If the reading exceeds 20 ppm, then the Sediment Filter will need to be replaced (Part # P-WAT-2414).
- If the Readings are above 40 ppm, the membranes (P-WAT- 2402) will need to be replaced.
* The Membranes should be replaced every 600,000 vehicles but this may vary from site to site.
