13. Identify a location downstream of the VREL control valve after secondary cooling.
14. Once the tubing is cut, deburr all cut edges to prevent shavings from entering sample
lines.
15. Paying attention to the direction of ow listed on the ow meter (if listed), install the
ow meter.
 NOTE
Since each panel is unique, the complexity of ow meter installation will vary.
16. Install the provided cable gland in the 1-7/64-inch hole.
17. Once the ow meter is mounted, carefully route wires over to the back of the
AutoVREL ow controller and slide them through the cable gland and wire channel
until they are exposed to the front of the drive unit. This will be connected to the
controller.
Take care when installing connectors. They are delicate and can be damaged easily.
18. With the AutoVREL ow controller in one hand, carefully connect the wire harnesses
to the connectors on the back side of the controller. The TSV switch wiring should be
made to the Alarm Conn header pins 4 and 6.
