2.5 WATER INLET AND OUTLET PIPING
The locations of the 2" NPT cold water inlet and hot water outlet piping connections are shown
in Figure 2-3a. Flow rates through the unit are limited to 50 gpm continuous.
Shut-off valves and union connections must be installed in the inlet and outlet lines for
maintenance. The use of dielectric unions is recommended.
NOTE
All piping must be arranged so that it does not interfere with
removal of any covers, inhibit service or maintenance, or prevent
access between the unit and walls, or another unit.
