4.Connect the Union (37) to the Coupler (34). Make sure to hand tighten only. Over-tightening may cause the Union to crack. Then, connect a 1-1/2”diam- eter Discharge Pipe to the Union. NOTE: Make sure the Discharge Pipe is secured to a solid surface, with appropriate hardware (not included), to ensure the stability of the Pump. (See Figure E.)

5.Install an additional union (not included) or other means of separating the Dis- charge Pipe just above the floor to facilitate removal of the Pump if necessary.

(See Figure E.)

6.A check valve (not included) is recommended just above, or in place of, the Union to prevent the backflow of water after each pump cycle. If a Check Valve is used, a 1/8” diameter air bleed hole should be drilled through the Discharge Pipe just above the lower Union (37) to prevent Pump “airlock”. A small spray of water out of this hole is normal while the Pump is running. (See Figure E.)
