INSTALLATION (cont’d)
ENSURE THAT THE EMERGENCY (E-STOP) STOP IS NOT ENERGIZED
4. Three-phase Proportioner Only: Check the Electric Motor to ensure rotation is
clockwise. Remove the inspection cover from the motor bell housing when
viewing the end of the Electric Motor. A counter clockwise rotation indicates two of the
incoming power leads need to be reversed.
CAUTION! Ensure Main Power switch is OFF and incoming power is locked
OFF before reversing power leads.
Recheck the rotation before proceeding with Installation (3 Phase only).
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, which makes it difficult to swap connections.
NOTE! The material delivery Heated Hoses are caped 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 required 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.
