17InRow RC Installation
Connect piping
See “Piping Diagrams,” beginning on page 8, for recommended valve, flexible adapter, and
strainer installation locations.
1. Route all piping 1 to the InRow RC in compliance with all local and national codes.
Note: Circuit setters are required to regulate the flow of chilled water to each piece of
equipment. When a CDU is used in conjunction with the equipment, circuit setters are
not required, as the CDU provides the flow-regulating function.
Note: The figure shows a top piping installation with a PEX fitting. Bottom piping
installations or rigid piping fittings are handled similarly.
2. Disassemble the union on the entering or exiting water line:
a. Remove the nut 3 from the body 6.
b. Remove the disc 4 and gasket 5. Save the gasket.
c. The disc 4 prevents water flow through the union.
Discard the disc 4.
3. Repeat step 2 for the union on the other water line.
4. Assemble the union on the entering or exiting water line:
a. Use thread sealant and thread sealing tape in accordance
with local and national codes.
b. Slide the nut 3 onto the fitting 2.
c. Seat the gasket 5 into the body 6.
d. Tighten the body 6 onto the nut 3, using a properly-
sized open end wrench.
5. Repeat steps 1 through 4 for the union on the other water line.
