Key:

RMain Disconnect Switch - Controls power to all circuits. It must be ON for proportioning unit to operate. Temperature displays are lit when main switch is ON.

SMain Air Filter - Filters system air supply.

TResin (B) Pressure Gauge - Displays pressure in resin proportioning system (B side).

UResin (B) - Inlet Supply Valve

VResin (B) Fluid Y-Strainer

WISO (A) Pressure Gauge - Displays pressure in isocyanate proportioning system (A side).

XISO (A) - Inlet Supply Valve

YISO (A) Fluid Y-Strainer

ZISO (A) Pump Lube System - (A side only)

AAISO (A) - Packing Nut and Lube Cup - (A side only)

*ABPressure Limit Switches - Factory set to turn off air drive system when proportioning pump exceeds designed operating pressure limit.

*ACPrimary Heater Thermocouple - Senses temperature of primary heater and inputs that information.

AD FTS Jumper Harness - Carries electrical signal from FTS sensor in isocyanate hose to hose temperature controller.

*AEAir Motor Reversing Switch - (Front of air motor) Energizes and de-energizes air solenoid valve coils to reverse direction.

*AF Primary Heater - Heats material to required dispensing temperature.

AG ISO (A) - (Isocyanate) Proportioning Pump - Draws in and dispenses a fixed volume of isocyanate to gun.

Component Identification

AH Resin (B) Proportioning Pump - Draws in and dispenses a fixed volume of resin to gun.

AI Power-Lock™Hose Heat Connection - Connects
