OPERATING PRINCIPLES
In order to maintain and troubleshoot the GL16 safely and effectively, it is necessary to understand
how the unit works. This chapter is divided into the five operating systems and individual components of
the unit:
5.1 Electrical System
5.2 Mechanical System
5.3 Exhaust System
5.4 Heating System
5.5 Sequence of Operation
Electrical System: This section reviews incoming power requirements, how power is distributed
throughout the unit, the controls, sensors and switches used to operate the
unit, and the safety buttons and switches used to provide a safe system.
Mechanical System: This section reviews the drive mechanisms which power all rotating and moving
parts and how they enable the ironing cylinder to produce the flatwork finish.
Exhaust System: This section explains how the exhaust blower and sail switch work together in
the exhaust canopy to provide ventilation for the unit.
Heating System: This section reviews incoming gas requirements, how gas is used to heat the
ironing cylinder, and the control, safety buttons, and switches used to provide
a safe combustion heating system.
Sequence of Operation: This section provides a step-by-step guide to the unit’s four stages of operation:
Stand-By, Mechanical Start-Up, Heating System Normal Operation, and
Heating System Fail-Safe Protection. Refer to the diagrams in the
SCHEMATICS section of this manual to follow the timing and sequence of
events.
5.1 Electrical System
Components that make up the electrical system are located in the following areas:
• Main Electrical Box
• Right End Frame
The following schematic references are found on the schematic diagrams in this manual. For more
