Some 3-phase models utilize a 3-phase motor. The motor must rotate counter- clockwise when viewed from shaft end. To reverse rotation, disconnect power and reverse power leads L1 and L2.

5.Connect feed pumps

a.Install feed pumps (K) in component A and B supply drums. See FIG. 1 and FIG. 2, pages 14 and 15.

A minimum feed pressure of 50 psi (0.35 MPa, 3.5 bar) is required at both feed inlet pressure gauges (FP). Maxi- mum feed pressure is 250 psi (1.75 MPa, 17.5 bar). Maintain A and B feed pressures within 10% of each other.

b.Seal component A drum and use desic- cant dryer (M) in vent.

Setup

c.Install agitator (L) in component B drum, if necessary.

d.Ensure A and B inlet valves (FV) are closed.
