INSTALL SUCTION LINE TO PUMP HEAD
1.
Uncoil the suction/discharge line. Use outside of solution tank as a guide to cut proper length of suction line
ensuring it will be 2-3" above the bottom of solution tank.
Allow sufficient slack to avoid kinks and stress cracks. Always make a clean square cut to assure that the
suction line is burr free. Normal maintenance requires trimming.
Suction lines that extend to the bottom of the tank can result in debris pickup leading to clogged injectors
and possible tube failure.

and ferrule and finger tighten to the corresponding
tube fittings.

Finger tighten nut to the threaded tube fitting while holding the tube fitting.
Over tightening the ferrule and nut may result in damaged fittings, crushed ferrules, and air pick up.
