Be sure to get the face and the threads. Hand tighten
the quick connect, making sure they thread correctly.
Tighten with the correct wrenches (13/16", ¾", and
15/16"). Tighten to 10-12 ft-lbs.
note:
Any hissing that is heard during the tightening process,
is caused by the fittings that are not quite in line. DO
NOT STOP TIGHTENING. Keep tightening, and the
hissing will stop.
Connect the TSEP (temperature sensor cord located
on CHEB) to the PLB. Connect the electrical connec-
tors between the CHEB and PLB (the ones in the split
loom). Route and clip to prevent chafing.
Connect the ductwork to the CHEB, use the hose
clamps to secure. It may be difficult to get the 6" duct
on, but it will connect. Use only as much duct as you
have to, as extra duct will impede air flow.
Install the 3/8" drain fitting into the bottom of the
CHEB from the under side of the truck, finger tighten.
Place the hose clamp over the end of the P-trap.
Push the end of the P-trap over the drain fitting, and
tighten clamp.
