OPERATING PRINCIPLES
In order to maintain and troubleshoot the Comet Executive™ Gas safely and eectively, it is necessary
to understand how the unit works. This chapter is divided into four operating systems and a review of
how these system are controlled to iron atwork:
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 ironer, and the controls, sensors and
switches operating the unit.
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 atwork nish and deliver it to the front of the unit.
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 each of the
ironer’s phases of operation: Stand-By, Jog Reverse Operation;
Mechanical Start-Up, and Burner Operation. Refer to the schematic
diagrams in the SCHEMATIC PARTS LIST to follow the
timing and sequence of events.
