Install Aqua-Sensor

1. Measure the sensor cable length as shown in Figure 2 and Table 1 (the Aqua-Sensor cord is set
at the factory for a 9" tank).
Tank Model
9" Quadra-Hull™ Tank
10" Quadra-Hull Tank
12" Quadra-Hull Tank
14" Quadra-Hull Tank
NOTE Use only one Aqua-Sensor probe for HE Twin
applications.
2. Loosen the small Aqua-Sensor Plug; a needle-nose pliers works
best. See Figure 3.
3. Moisten the cable sheath and slide the cable grip up or down to
the proper cable length.
4. Tighten the small Aqua-Sensor plug so that the fitting cannot slide
along the cable.
NOTE There must be no kinks or bends in the cable.
5. Insert the probe and cable through the Aqua-Sensor port.
6. Tighten the Aqua-Sensor plug into the Aqua-Sensor port.
NOTE The media tank must be backwashed so that the Aqua-Sensor probe can
fall into the proper position. See "Recommended Aqua-Sensor® Start-Up
Procedure" on page <?>.
Mount the Control Valve
See Figure 4 for an illustration on mounting the control valve to the tank.
1. Assemble the O-rings, located in the parts pack, to the tank adapter.
2. The valve adapter O-ring sits on the first step on the adapter. See Figure 5.
NOTE Do not push the top O-ring down to the flange surface on the adapter.
NOTE The larger of the two O-rings in the parts should be positioned between the
adapter and the valve. Do not stretch the smaller O-ring onto the top of the
tank adapter.
3. Lubricate only the top O-ring on the tank adapter and the outlet manifold o-ring with silicone lubri-
cant.
4. Screw the adapter into the tank until the adapter bottoms out on the tank flange.
NOTE The adapter only needs to be tightened hand-tight to the tank flange.
5. Align the manifold with the center opening in the valve, and firmly press the valve onto the adapter.
NOTE Make sure to push the valve straight down onto the manifold. If the valve is
cocked, it may cause the O-ring to slip off the manifold.
6. Assemble the tank clamp to the control, and tighten the clamp screw.
