3.1 Receiving Inspection
Inspect all material received for shipping damage. Confirm that your shipment includes all material
and options ordered. If materials are missing or damaged, the carrier that made the delivery must be
notified within 15 days of delivery in accordance with Interstate Commerce regulations in order to
file a valid claim with the carrier. Any damaged material including all containers and packing should
be held for carrier inspection. Contact our Customer Service Department, 6450 Dry Creek Parkway,
Longmont, Colorado 80503, phone 303-652-4400 if your shipment is not correct for reasons other
than shipping damage.
3.1.1 Damaged Material
Any damaged material, including all containers and packaging, should be held for carrier inspection.
If your shipment is not correct for reasons other than shipping damage, contact our Customer Service
Department, 6450 Dry Creek Parkway, Longmont, Colorado 80503, or telephone 303-652-4400.
3.1.1.1 International Shipments
If an airfreight forwarder handles the shipment and their agent delivers the shipment to customs the
claim must be filed with the airfreight forwarder.
If an airfreight forwarder delivers the shipment to a specific airline and the airline delivers the
shipment to customs the claim must be filed with the airline, not the freight forwarder.
3.2 Important Considerations for Installation of the Mini-Convectron Module
• It is recommended that the Mini-Convectron be installed with the port oriented vertically
downward to ensure that no system condensates or other liquids collect in the gauge tube. The
gauge tube axis must be horizontal if it is to be used at pressures above 1 Torr. Although the gauge
tube will read correctly below 1 Torr when mounted in any position, erroneous readings will
result at pressures above 1 Torr if the gauge tube axis is not horizontal.
• Do not use a compression mount (quick connect) for attaching the Mini-Convectron to the
system in applications resulting in positive pressures in the gauge tube. Positive pressures might
blow the gauge tube out of a compression fitting and damage equipment and injure personnel.
Pipe thread or flange mounting systems should be used for positive pressure applications. In any
case, the absolute pressure in the gauge tube should not exceed 1000 Torr.
• Do not perform electrical continuity tests on the Mini-Convectron gauge tube with instruments
applying voltages in excess of 1 volt when the gauge tube is at vacuum, or 5 volts when at
atmospheric pressure. Exceeding these voltages will damage the sensing element.
• Keep the gauge tube clean. Do not remove the mounting port cover until you are ready to install
the gauge tube.
• Do not mount the Mini-Convectron in a manner that allows deposition of process vapors onto
the internal surfaces of the gauge tube through line-of-sight access to the interior of the gauge
tube.
• Do not install the Mini-Convectron where high amplitudes of vibration are present. Excessive
vibration will cause forced convection at high pressure giving erroneous readings.
• Do not bake the Mini-Convectron Module at temperatures exceeding 85 °C.
