Likewise, if the pipe is not completely full of water or air bubbles are present, the flow meter should be
installed in the side or bottom of the pipe to prevent interference. Lastly, the flow meter cable is 8m (26.4 ft)
and may be cut or extended up to 15m (48.7 feet) as needed. The distance to the controller must not exceed
this maximum.
6.4.2 Hardware and Plumbing Installation
1.
Drill an appropriate size hole (based on the saddle clamp and flow meter) in the main return
pipe from the filter based on the criteria listed in 0.
2.
Install the saddle clamp
3.
Lubricate the sensor o-ring with a silicone lubricant. DO NOT use a petroleum-based lubricant,
as this may deteriorate the o-ring.
4.
Insert the flow meter into the saddle clamp, aligning the tab on the flow meter with the notch on
the saddle clamp.
5.
Hand tighten the flow meter cap. DO NOT use tools or over tighten.
6.4.3 Electrical Installation
1.
Pass the flow sensor cable through an open glad on the bottom of the controller.
2.
Connect the three wires from the sensor cable to the last terminal block on the lower right
corner of the I/O Module, following the color order indicated on the module.
The sensor cable may be cut or extended up to a maximum distance of 15m (48.7 feet) as needed.
