important to understand that the input regulator for GAS 2 must be of the
relieving type for safety reasons; once a pressure is set with the regulator,
reducing the setting with the acid system in operation will release a small
quantity of acid gas into the machine enclosure.
3.3.2 Cooling Water Supply
Turn on the cooling water supply or optional cooling water chiller and pump. If
the coolant flow alarm has been disconnected from the system this step will not
be required.
3.3.3 Main Disconnect
Turn on the main disconnect switch on the rear electrical enclosure.
DANGER! Dangerous voltages are now present throughout the
machine enclosure.
3.3.4 Control Power Switch
Turn on the Control Power Switch. The Control Power Indicator (green lamp)
illuminates. The ¼ DIN Ramping Controller boots up and the Main Page
appears on the Lower Display.
3.3.5 Vacuum Pump
Turn on the vacuum system or optional vacuum pump.
3.3.6 Tool Installation
Open the Lid
• Press the Lid Cycle Switch. A timed Exhaust Cycle will be followed by
a timed Vacuum Cycle.
• Pull the handle forward and move it to the UP position.
• Press the Lid Cycle Switch. A timed Backfill Cycle will return the
chamber to atmospheric pressure.
• Raise the lid to the open position.
Install Tool
The test tool used with the machine test profile must be comprised of a bare
target plate, SST #35228.
• Ensure that the heating element has been installed (see Section 2.2.4).
• Align the tool with the four tabs of the radiation shield.
• Carefully lower the tool until it touches the tabs.
Install Control Thermocouple
The control thermocouple must be in continuous contact with the tool for the
temperature control system to function. Holes are drilled in the long edges of the
tool (one on each side), so that one hole will be available for the thermocouple
