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 F
IG. 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 F
IG. 7.
c. Remove ferrule and apply oxide inhibitor to bare
wire. See F
IG. 8.
d. Reinsert wire in ferrule and apply more oxide
inhibitor to ferrule and wire end.
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 F
IG. 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.
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 F
IG. 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.
