SECTION 12. SUGGESTED THIRD-PARTY
COMPONENTS
Note:
These are guidelines useful for many installations, but selection of third-party
components is at the discretion of the system installer or vehicle manufacturer.
A. Suggested components for CAFS discharges:
The installer must provide fittings and tubing to connect the CAFS components to the
vehicle's discharge outlets. These are suggested parts for the common discharge
sizes. If the planned discharge system is not covered in this guideline, please
contact Waterous.
Note: Waterous strongly suggests that every CAFS discharge have an air check valve
and a water check valve, as shown below.
The air check valve prevents foam solution from back-flowing into the compressor
and contaminating the oil. The water check valve isolates the discharge, preventing
CAF from back-flowing into the foam solution manifold and exiting through another
discharge. This makes it possible to flow solution through one discharge and CAF
through another.
