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. Insert the heater and temperature probe into the detector’s heater block.
2. Install the detector on the GC using two screws. Refer to Figure 3 or 4,
