Installation
General Precautions
• Do not use plastic/polymer or copper tubes for gas handling and
interconnectons. Use only stainless steel tubing with Valco gold-plated
ferrules.
• Do not turn the unit on until the helium discharge gas is flowing through
the detector.
• Do not shut off or disconnect the discharge gas when the detector is hot,
even if the unit is turned off. Turn off the discharge and allow the detector to
cool down naturally before disconnecting or shutting off the discharge gas.
• Do not cover the unit with materials or devices which would restrict air
circulation.
• Position the controller unit where the mains switch on the rear panel can
be reached easily.
Mounting the Detector on the GC
1. Remove the cover plates and insulation on detector position #4 (to the
right). Remove the heater block screw. (NOTE: The detector will also fit
in Postion #2, but the cover plate supplied with the detector will not fit.)
2. Place the detector on the top of the GC as shown in Figure 3 and secure
it with the heater block screw.
3. Install the cover plate provided by Valco as part of the detector system.
