X8 and X8-D Extension Installation

Before installing the X8 or X8-D, basin extension, the pump and cover
must be removed from an assembled PRO system.

1.) Remove the small access cover which is secured by 6
fasteners.

2.) Remove the QuickTree® (float rod and floats) from the basin by
lifting the unit out of its holder.

3.) Unscrew the fasteners securing the main cover to the tank. In
order to remove the main cover it must be separated from the
PVC discharge pipe. This can be done by rotating the cover
back and forth while pulling upward.

Re-assembly:

1) The short length of pipe and the coupling must be “glued” to the
current discharge pipe(s).

2) Place the pump(s) with pipe into the basin and position it within
the torque stops. (The torque stops are the three round pockets
located at the bottom of the basin.) Each leg of the pump should
be in side one of the pockets.

3) The gasket can now be placed onto the tank’s rim, match the
holes in the gasket with the threaded inserts in the tank.

4) Lower the extension onto the gasket carefully as to not disturb
the gasket.

5) Using the screws and washers provided, attach the
extension to the tank. Note: an XL system will require 16
screws to provide proper claming load. The torque on the
fastener should be 40 in*lbs IMPORTANT: do not over
tighten.

6) Re-attach the main cover. To facilitate assembly, the PVC
pipe should be wetted with soapy water and inserted into the
rubber seal under the cover. The cover can be twisted back
and forth while pushing down until the cover meets the
extension. Re-attach the cover with the same screws that
were removed. Note: XL-systems will have 16 screws.

7) A new longer QuickTree® rod is provided with the X8
extension. Remove the floats from the original QuickTree®
rod by loosening the screw on the clamp. (For systems with
an optional alarm, two floats need to be removed.)

8) Re-attach the floats to the new longer QuickTree® rod using the diagram (Figure 1 or 2)
below. IMPORTANT: It is critical that the tether length remains the same on re-

installation. The tether length is the distance of cord from the clamp to the top of
the float ball. See Figure 1 or 2. for proper lengths.

9) The new QuickTree® rod has four “flat” sections; the upper two are used in a P380
system and the lower two on a P370 system. The lowest float is the pump control
followed by the alarm float if the system is equipped with the alarm option.
