4.3 Cooling Water Connections
Specifications The differential pressure required between the water inlet and outlet
connections is 30 to 45 psi (0.2 to 0.3 MPa). The maximum allowable
water pressure is 120 psi (0.83 MPa). The water supply must be capable
of providing water flow at a rate indicated in Table 1-1. See Table 1-2
for the maximum cooling water heat load.
Water connections Use a 1.5 in. (38 mm) water service hose to connect the water supply and
drain to the heat exchanger water inlet and outlet connections (figure
