Yellow background with legends shall also be installed. The ironer shall also be equipped with a normal equipment stop button (colored RED). All operational and functional buttons/switches shall be labeled as to the function of the button or switch.Provide 4-Plex GFI receptacle at each equipment location for mechanics use.An hour meter shall be installed on each flatwork ironer that will show actual hours of run time of the ironers.Spreader Feeder machine, Thermal Fluid Ironer and folder cross folder with large piece stacker shall be inter-locked to make complete system that includes emergency stops and quality grading.The flatwork ironer shall be equipped with a totalizing non-resettable gas meter. The non-resettable gas meter is required for the flatwork ironer and heater to prove fuel consumption is less than the heat input limit in therms per year.Sufficient fresh air supply is essential to ensure optimum combustion and the area of air supply openings must be in compliance with applicable codes and regulations. Air openings must be kept wide open when the burner is firing and clear from restriction to flow.Proper venting is essential to assure efficient combustion. Insufficient draft or overdraft will promote hazards and inefficient burning. The successful contractor shall insure that vents are in good condition, sized properly and with no obstructions.All piping within the flatwork ironer will be insulated and wrapped in white textured aluminum, identified and have directional flow markings installed.Ordering Data Medium Production Folder Cross Folder with Large Piece Stacker Conveyor:Furnish and install one (1) each – Four lane primary and three cross fold combination folder-cross-folder. Folder shall be an integral unit equipped with a conveyor feed and capable of meeting ironer production requirements. Production requirements - 900 sheets per hour, 900 pillowcases per hour, 900 (36?inches X 36 inches) double thickness cotton surgical wraps per hour, 900 (24 inches X 24 inches) double thickness cotton surgical wraps per hour.The folder cross folder shall have a color touch screen controls & information system” that incorporate automatic/manual machine operation, self-testing, fault display and built-in bination folder-cross folder, four-lane.Four-lane folder cross folder shall be capable of receiving small pieces from the flatwork ironer.Electrical characteristics - 208 volts, 3 phase, 60 cycles.Folding machine shall be installed, leveled and have a leveling device installed on the machine.Folding machine, stacker and conveyor shall be equipped with four (4) lockable casters.Folding machine and conveyor shall be electrically interlocked to the ironing system.Each lane shall be equipped with a counter to determine the number of small pieces folded.Each folder shall be equipped with quality grading controls for rips, tears and stains and shall work in conjunction with the spreader feeder machine.The folding machine and stacker shall be equipped with an illuminating emergency stop buttons (colored RED) when activated, inter-locked with the entire ironing system and when activated shall render the entire ironing system (spreader feeder. ironer, folder cross-folder and stacker) inoperable. The folding machine and stacker shall also be equipped with a normal stop button colored Red. All operational and functional buttons/switches shall be labeled as to the function of the button or switch. Yellow background with legends shall also be installed.Folder shall have reverse jog capability.The folder cross folder control shall be a field programmable microprocessor or color touch screen control. The folder cross folder control shall be capable of changing the operation of the entire automated folder cross folder system to the required functional configuration for the specific item being processed by simply choosing the appropriate program. A lock out feature shall be included to prevent unauthorized programming.The folder cross-folder shall be equipped with trouble shooting for use in case of a component failure.The folder cross-folder shall be equipped with a totalizing digital display counter on each of the folding lanes.The folder cross folder shall operate compatibly with the flatwork ironer operating at a minimum speed range from 30 feet per minute to 170 feet per minute.The stacker conveyor shall operate as an integral part of the folder cross-folder.The stacker conveyor shall maintain the quality of the folded items during the stacking process.The stacker conveyor shall be capable of receiving folded flatwork from the folder cross-folder and drop release the flatwork into precise stack by using a combination centering conveyor.The stacker shall be microprocessor controlled.The stacker conveyor shall operate with a predetermined stack count of up to 20 large piece flatwork items and shall automatically transport in increments providing space for the next stack.The stacker conveyor shall have lockable casters and be of the modular concept so that it can simply be plugged into the folder cross-folder for utility connections by using quick disconnects.Electrical characteristics - 208 volts, 3 phase, 60?cycles.For allowing visual observation of the mechanical systems, install scratch and shatter-proof, clear (for the equipment life expectancy), Lucite side panels / doors on both the right and left sides of the folder-cross folder and stacker in lieu of metal side panels.Safety micro switches shall be installed on all doors of the folder cross folder and stacker so that when a door is opened, the machine shuts down.An hour meter shall be installed on each folder that will show actual hours of run time of the folders. ................
