PCU Safety Instructions
Before using your PCU, read the following safety instructions to make sure you use the equipment safely
and effectively.
• The electronics and heating element use dangerous electrical voltages. To reduce the chance of
personal injury or property damage, turn off and unplug the PCU when maintaining the system.
• Always turn off the PCU using the Heater switch on the control panel first. When the PCU
temperature reads less than 100
°C it is safe to turn off the PCU by the main power switch in the back
of the unit. Failure to follow this could result in a shortening of the life of the mechanism that moves
the plate through the PCU.
• The PCU heater reaches high temperatures during plate curing. Do not touch the slot area where the
plate comes out on the tray.
• Aluminum plates are hot when they exit the PCU. Let the plate cool before removing from the tray.
• Make sure the plate is dry when feeding it into the PCU; if the plate is wet, it could create steam and
cause burns.
• Do not open the PCU because of electric shock danger.
• Do not run the PCU with the protective cover open or removed.
• Place the PCU on a flat, level, stable surface that is larger than the unit. The PCU will not operate
properly if it is tilted or at an angle.
• The PCU weighs about 55 lb (25 kg) in the box and is bulky, so it should be handled by two people.
• Do not disable the safety mechanisms installed by the manufacturer in the PCU.
