Installation

NOTE: Be careful not to cut or nick copper strands. If more than five strands are cut or nicked, trim wire and re-strip.

New hoses are pre-stripped at correct length; remove insulation to expose bare wire.

a.Ensure strip length is correct by fitting ferrule over exposed wire. Ferrule should be flush with wire end. See FIG. 7.

NOTE: On some older heated hoses wire insulation will not fit inside ferrule insulator. In these cases, use scissors to split and remove ferrule insulator.

b.If wire is short of ferrule end, adjust strip length accordingly. If bare wire is protruding from fer- rule, trim flush to ferrule end. See FIG. 7.

6.Pair electrical wires as follows: A-Hose to A-Hose; B-Hose to B-Hose.

NOTE: When connecting first hose section to pro- portioner, wire pairing does not make a difference.

a.Insert one wire from heated hose into connec- tor. Ensure that ferrule is mating with connector insert. See FIG. 9.

b.Thread in setscrew and use hex wrench to torque setscrew to 60 in-lbs (6.78 N•m).

NOTE: To reach approximately 60 in-lbs (6.78 N•m), complete 4.5 revolutions with hex wrench after set- screw comes in contact with ferrule.

FIG. 10: Torque Setscrew

c.Insert remaining wire from pair into connector; ensure proper insertion depth. Thread setscrew and torque to 60 in-lbs (6.78 N•m); see sub-step B. See FIG. 9 and FIG. 10.

d.Repeat sub-steps A through C for remaining wire pair.

e.Re-torque all setscrews to 60 in-lbs (6.78 N•m).

NOTE: When torqued to 60 in-lbs (6.78 N•m) set- screws will be approximately flush with connector. See FIG. 11.
