CONNECT DRAIN ASSEMBLY
If you are NOT using the Forward Flush Kit:
1.
Connect the Forward Flush Tube with Manual Shut-Off Valve (19) to the John Guest Elbow
at the bottom of the Lower Tank Assembly (10) on the assembled Membrane Vessel. Hold
the Lower Tank Assembly in your hand when you push the tube in so that you do not apply
pressure on the assembly that may break it. The Shut-Off valve should face forward and be
accessible for servicing.
2.
Connect the Upper Drain Assembly’s (12) John Guest Tee Connector to the tube at the top
of the Forward Flush Tube with Manual Shut-Off (Part #19). The John Guest elbow should
be located at the top. The 1” NPT threaded fitting should extend towards the wall and will
be later connected to the drain. This is the main drain port of the system.
3.
Rotate the Drain Flow Restrictor Assembly (11) so that it aligns with the John Guest elbow
at the top of the Upper Drain Assembly (12), ensuring that the Forward Flush tube (19) is
perfectly vertical (Drain Flow Restrictor Assembly is perfectly aligned with the elbow on the
Lower Tank Assembly). Connect them.
If you are using the Forward Flush Kit: (
UP-FF
):
1.
Connect the Forward Flush Tube (15) to the John Guest Elbow at the bottom of the Lower Tank
Assembly (10) on the assembled Membrane Vessel. Hold the Lower Tank Assembly (10) in
your hand when you push the tube in so that you do not apply pressure on the assembly
that may break it.
2.
Connect the Forward Flush Solenoid Valve (17) to the Forward Flush Tube (15) using the
Asco Quick Connect Fitting. Confirm that the flow direction on the solenoid valve is
upward by examining the arrow on the solenoid valve body. This is extremely important.
If installed backwards, the solenoid will not function properly. Also, note that the Back
Flush and Forward Flush solenoids, while they look virtually identical, have opposite
internal functions. Be sure that you install the correct valve.
3.
Connect the Upper Drain Assembly’s (12) John Guest Tee Connector to the tube at the top
of the Forward Flush Solenoid Valve (17). The John Guest elbow should be located at the
top. The 1” NPT threaded fitting should extend towards the wall and will be later
connected to the drain. This is the main drain port of the system.

perfectly vertical (Drain Flow Restrictor Assembly is perfectly aligned with the elbow on the
Lower Tank Assembly). Connect them.
