See “Piping Diagrams,” beginning on page 8, for recommended valve, flexible adapter, and

strainer installation locations.

1. Route all piping

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.

Condensate pump. The pump is factory-wired and piped

internally to the lower condensate pan. The pump is capable of

moving liquid a maximum of 15.2 m (50 ft), including

maximum lift of 4.9 m (16 ft). For example, if your lift is 3 m

(10 ft), you have 12.2 m (40 ft) of usable run. The pump also

uses an on-board condensate high level float switch, which is

wired into the InRow RC alarm input for local

and remote alarm capabilities.
