Drain Line Flow Control
Disassembly and Inspection
Depending on the flow control installed on the unit, remove the red plastic retaining clip (plastic flow control) or the (4) screws
(stainless steel flow control) to expose the flow control and retainer. The flow controls can be removed by flexing the washer with
a small screwdriver being careful not to mar the plastic seat. The flow control and retainer may be chemically cleaned using dilute
sodium bisulfite or vinegar, do not clean with abrasive methods.
Reassembly
Insert the flow washers back into their respective bores, confirming correct flow control orientation (see diagram in the exploded
view section). Place back into the housing and reassemble the housing /fitting. Do not use Vaseline, oils or other unacceptable
lubricants on O-rings. A silicone lubricant may be used on the O-ring of the elbow or the retainer, but not on the flow control or its
seat.
