DESCRIPTION of ESP101 modication: The wiring modication (interconnect plug reversal) redirects the control signal
from the ESP-101 internal solenoid, to the pins within the torch connection panel receptacle. The control signal is then
diverted to the solenoid within the Remote Junction Box.
The hose modication (solenoid air bypass) directs the system air supply to the solenoid within the Remote Junction Box.
This ensures air at a sucient pressure is immediately available to the PT-37 torch.
SECTION 3 INSTALLATION
