Page 33: Control Overview
CONTROL OVERVIEW Light Switch Controls the oven chamber light. Power Switch Controls all power to the oven and its systems. Set Temperature Display and Controls Shows the current chamber temperature. The Up and Down arrow buttons are used to access the Temperature Set Point (SP) or Calibration Offset (C O) display modes and input the temperature set point or calibration adjustment value. - Page 34 CONTROL Vacuum Gauge This gauge is set at the factory to show the chamber vacuum level relative to sea level atmospheric pressure in inches of mercury (inHg). The display range is 0 to -29.9inHg. Zero is the room atmosphere pressure at sea level and -29.9inHg a near-perfect vacuum. See page 44 for how to display other units of measurement or zero the gauge to your local altitude.

Page 35: Operation
OPERATION Safe operation of the oven is dependent on the actions and behavior of the oven operators. Operating personnel must read and understand the Safety Guidelines and Operating Precautions in this section prior to operating the oven. The operators must follow these instructions to prevent injuries and to safeguard their health, environment, and the materials being treated in the oven, as well as to prevent damage to the oven. -

Page 37: Theory Of Operation
OPERATION HEORY OF PERATION Vacuum Vacuum is supplied by an external vacuum supply (a pump or building system) connected to one of the oven vacuum ports. Vacuum levels obtained in the oven chamber are dependent on pump type and performance, valve settings, and the nature of the application or process, including the volume of materials outgassed. - Page 38 OPERATION Heating Control The oven controller monitors the chamber shelving temperature using a thermocouple temperature probe extending into the chamber from the back wall. In a vacuum environment, the probe senses the temperature of the shelf placed immediately above it. Placement of a shelf in close proximity to, but not in contact with the probe, is crucial for accurate measurement of the shelving temperature in the vacuum chamber.

Page 45: Maximum Obtainable Vacuum
OPERATION AXIMUM BTAINABLE ACUUM The maximum vacuum obtainable, as measured by the oven gauge, is in part a function of altitude While a vacuum pump will evacuate the same percentage of atmosphere from the oven chamber at higher altitudes, less overall pressure is expelled because of the reduced density. Put differently, at sea level there are 29.9 inches of mercury pressure that can be drawn out of the oven chamber by a vacuum pump. -
Page 46: Oven Cooldowns
OPERATION OOLDOWNS The oven chamber is well insulated and requires a significant length of time to cool down while remaining sealed. • 6 hours may be required to cool down from 150°C to 100°C. • 16 hours may be needed for the oven to return to room temperature cooling from 150°C. •... -
