c) Connect the ground wire on the gun hose to the ground point on the TSU.
d) Connect the heated hose assemblies to the TSU, taking care not to cross-thread
or over-tighten the fittings, thereby ensuring a leak-proof chemical connection.
e) Connect the TSU harness to the TSU. To ensure a secure electrical connection,
place the protective electrical isolator boot over each plug and tape together.
f) Cut the isolator in half crosswise and secure the two pieces in place between the
hydraulic fittings.
g) Connect and tighten the air hoses.
h) Plug the Power-Lock hose heat connectors together. Secure the connection in
place with the cable tie provided; failure to do so could cause a disruption in the
hose heat system should the connectors separate.
6. Install the optional hose scuff jacket, if used, over the hose lengths.
7. Connect the coupling block to the gun whip hose and make sure that the manual
valves are closed.
