Heated Hose Installation
CAUTION! The material delivery Heated Hoses are color coded Red and
Blue allowing the user to recognize them. The Red corresponds to the
Isocyanate (Iso, A) and the Blue to the Polyol (Poly, R). To avoid connection
errors, the Coupling Connections of the Iso (A) and Poly (R) Heated Hoses
are also different sizes to ensure correct orientation.
NOTE! The material delivery Heated Hoses are capped at the ends to
prevent absorbing moisture. Do not remove caps until the Heated Hoses are
going to be installed on the Proportioner.
1. Lay out all the Heated Hose assemblies end to end aligning the Iso “A” (red) and Poly
“R” (blue) and connect the respective Coupling Connections using the appropriate
sized open-end wrench after ensuring Heated Hose assemblies lay flat.
CAUTION! Take care to not cross-thread or over-tighten the Coupling
Connections. Thread seal tape or compound is not recommended for this
tapered seat Coupling Connections.
2. Connect the material Heated Hoses to the outlets of the respective Heaters i.e. Iso (A)
Heated Hose to the Iso (A) Heater and the Poly (R) Heated Hose to the Poly (R)
Heater ensuring Heated Hose assemblies lay flat.
3. Connect Air Hose Coupling Connections.
4. Connect the Heated Hose power wires to the “Fast-Lock” Connector (Part # KT-
00029A) coming from the Hose Heat Transformer as follows:
a. Loosen the Socket Head Set Screw to allow
insertion of the Heated Hose electrical wire
Terminal.
b. Insert the Terminal into the “Fast-Lock”
Connector Body.
c. Securely tighten the Socket Head Set Screw.
d. Install electrical tape around Connector Body.
NOTE! A good practice is to add some
dielectric grease (Permatex 67VR or equivalent) to the outside of the
Terminal, where the electrical connection is made, prior to insertion.
Repeat the above steps to connect the “Fast-Lock” Connectors that you will find on all
Heated Hose power wire.
CAUTION! Ensure the proper mechanical and electrical connections of the
Heated Hoses are made to avoid possible material leakage and Hose heat
problems.
