IMPORTANT SAFETY INFORMATION
WARNING
Indicates information important to the proper operation of
the equipment. Failure to observe may result in damage to
the equipment
In addition to the warnings and cautions in this manual, use
the following guidelines for safe operation of the unit.
• Read all instructions before using equipment.
• For your safety, the equipment is furnished with a properly
grounded cord connector. Do not attempt to defeat the
grounded connector.
• Install or locate the equipment only for its intend-ed use as
described in this manual. Do not use corrosive chemicals in
this equipment.
• Do not operate this equipment if it has a damaged cord or
plug; if it is not working properly, or if it has been damaged or
dropped.
• This equipment should be serviced by qualified personnel
only. Contact the nearest Roundup authorized service facility
for adjustment or repair.
HOT SURFACE WARNING.
Indicates information important to the handling of
equipment and parts. Failure to observe caution could
result in personal injury.
The following warnings and cautions appear throughout this
manual and should be carefully observed.
• Turn the unit off, disconnect the power source and allow
unit to cool down before performing any service or
maintenance on the unit.
• The procedures in this chapter may include the use of
chemical products. These chemical products will be
highlighted with boldface letters followed by the abbreviated
HCS (Hazard Communication Standard). See Hazard
Communication Standard manual for the appropriate
Material Safety Data Sheets ( MSDS).
• The equipment should be grounded according to local
electrical codes to prevent the possibility of electrical shock.
It requires a grounded receptacle with separate electrical
lines, protected by fuses or circuit breaker of the proper
rating.
• Do not block or cover any openings on the unit.• Do not
immerse cord or plug in water.• Keep cord away from
heated surfaces.• Do not allow cord to hang over edge of
table or counter.

TECHNICAL THEORY OF OPERATION
When the power switch is on, line voltage flows to the primary side of the step down
transformer. The transformer’s secondary side supplies 12 & 24 VAC to the control board.
Once powered, & provided that the generator temperature is below 380 F, the control board
calls for heat by supplying 7-10 VDC to the solid state relay terminals 3 (+) 4 (-). Once
powered, the relay closes terminals 1 & 2, which allows line voltage to flow to the generator.
As the generator begins to heat up, a type “J” thermocouple monitors the internal generator
temperature. As the heat continues to increase, so does the thermocouple’s DC millivolts.
Once the generator’s temperature rises to 380-420 F (193-215 C), the thermocouple is
generating approximately 10-12 DC millivolts. The control board receives these millivolts &
proceeds to remove the 7-10 VDC to the solid state relay since the heating circuit has now
become satisfied. Then, relay terminals 1 & 2 open up, and the generator stops heating.
The heating circuit will cycle on & off as needed, even at idle. When the cycle start
(Momentary) button is pushed, it signals the control board to initiate a steam cycle.
The control board then supplies 24 VAC to the solenoid valve for approximately one second.
The solenoid opens, and allows a shot of water (approximately 25 ml or ¾ oz) to flow onto
the generator surface for steaming. Since the generator has an oval cover that is secured in
place with a wing nut, the steam is forced downward through the generator steam ports &
onto the product. This control board incorporates several Led’s for status & diagnostic
purposes. See “Led Layout” in Troubleshooting section of the technical manual. An audio
signal will sound for 3 seconds at the end of the cycle. If the heating circuit continues to call
for heat and the generator overheats, an automatic reset hi-limit will trip and open the
generator & transformer circuit. Once it cools down, the hi-limit will reset automatically.
NOTE: If this condition should repeat, the root cause must be determined & corrected.
