Circulation Pump
A calculation for proper pump selection must be performed for all installations. The pump(s)
should not be operated at maximum working pressures above 30 psi or maximum working
temperatures above 200°F and within limits advised by the manufacturer. The pump must not be
operated unless the system has been flushed, bled of all air and completely filled with water.
Recommended locations for the circulator, expansion tank, relief valve and other trim are
shown in Figures 1 - 7.
