The following is provided if heat trace is ordered as an option for the SCS:
• A bundle sleeve for the heat trace bundle to enter the SCS.
• A conduit hub to allow the heat trace cable to be routed to the exterior of
the SCS enclosure for power connection.
• A 1/4 in. tube bulkhead to interconnect the tube in the bundle to the SCS.
The customer is responsible for installing the heated tube bundle according to
the heat trace bundle sleeve manufacturer’s instructions.
Heated line seal installation
The heat-shrinkable entry seal Model NUS-4X supplied by Endress+Hauser
provides a waterproof fitting where the heat trace bundle enters the sample
conditioning system (SCS) enclosure. This seal consists of a three-part
assembly; a rigid plastic nylon nut, an O-Ring and the heat-shrinkable molded
area.
Tools
• Spanner wrench
• Heat gun
• RTV sealant
• Cable cutter
Use the following instructions to install this seal.
1. From the inside of the enclosure, place the rigid plastic nylon
threaded nut through the access hole to the exterior so that the nut
flanged end is up against the inside of the enclosure.
2. From the outside, place the O-Ring over the nut threaded end and
position against the enclosure.
3. Screw the shrinkable, internally threaded nose onto the rigid nut and
tighten using an appropriate sized spanner wrench.
Inserting the heat trace bundle
Refer to the manufacturers website for instructions on installing the heat trace
bundle.
All electrical connections must be made in a junction box supplied
by the customer and installed external to the SCS enclosure per
site requirements.
