6 RECEIVING & STORAGE / INSTALLATION Receiving and Storage Ensure that the protective caps placed over the ends of the bundle are firmly in place to protect from moisture. CAUTION: Fire hazard in hazardous locations. The insulation resisitance test can produce sparks. Be sure there are no flammable vapors in the area before performing this test. Insulation Resistance Criteria A clean, dry, properly installed circuit should measure thousands of megohms, regardless of the heating cable length or measuring voltage. The following criteria are provided to assist in determining the acceptability of an installation where optimum conditions may not apply. All insulation resistance values should be greater than 1 gigaohm (1000 megohms). All bundle ends must be sealed at all times. Protect from mechanical damage. Temperature Range - Storage -60 F to 140 F (-50 C to 60 C) TPU Jacket -30 F to 140 F (-35 C to 60 C) SV47 Jacket Minimum Installation Temperatures Minimum Minimum Identifier Description Installation Service Temperature Temperature S SV47-10 F (-23 C)* -30 F (-35 C) U TPU -40 F (-40 C)* -60 F (-50 C) *Allow tube bundle to rise above the minimum installation temperature if overnight temperatures fall below the minimum installation temperature. Electrical Insulation Resistance (Megger ) Test CAUTION: High voltage testing of electrical insulation poses potential shock hazard and should only be performed by qualified personnel. Frequency Electrical insulation resistance testing is recommended before installing the bundle, prior to initial start-up after bundle installation and as part of regularly scheduled maintenance. Procedure Insulation resistance testing (using a megohmmeter) should be conducted at 500 and 1,000 Vdc. First measure the resistance between the heating cable bus wires and the braid. 1. De-energize the circuit. 2. Disconnect the thermostat or controller if installed. 3. Disconnect bus wires from terminal block if installed. 4. Set test voltage at 0 Vdc. 5. Connect the negative (-) lead to the heating cable metallic braid. 6. Connect the positive (+) lead to both heating cable bus wires simultaneously. 7. Turn on the megohmmeter and set the voltage to 500 Vdc; apply the voltage for 1 minute. The meter needle should stop moving. Rapid deflection indicates a short. Record the insulation resistance value in the Inspection Record. 8. Repeat Steps 4-7 at 1000 Vd. 9. Turn off the megohmmeter. 10. If the megohmmeter does not self-discharge, discharge phase connection to ground with a suitable grounding rod. Disconnect the megohmmeter. 11. Reconnect the thermostat if installed. Planning Installation and Determining Length Route along existing structures such as beams and columns to provide support. Avoid areas where the ambient temperature may exceed 110 F (45 C). Maintain 1 /2" (12mm) minimum air gap between bundles. Measure square into corners. (The length required to make a 90 degree bend is about 13" (330mm). Measuring square into the corner will give you 16" (410mm). The extra 3" (80mm) is part of your safety factor to ensure you have enough length.) Allow 12" - 18" (300mm to 450mm) of straight tubing bundle before connecting to fittings. Allow enough heater cable to reach the junction box and make connections inside considering the minimum length requirements of applicable national and local electrical codes. If the bundle contains a JNx, JVx, T18, TN18 or TY18 heater see special instructions on the following page about locating first and last nodes. If the bundle is supplied with factory finished ends or factory installed temperature sensor, the "Power End", "Probe End" and "Temperature Sensor" location will be marked and must be installed as indicated. Uncoiling and Straightening Method 1 - Roll it out on the floor or other flat surface. This will leave a slight bow that can be taken out by hand. Method 2 - Use a second smaller spool to straighten the product as it is taken off of the larger shipping spool. 6

7 Instructions on this page are for Installation of STACKPAK with zone heaters. JNx, JVx, T18, TN18 and TY18 ONLY - DISREGARD FOR ALL OTHERS. + Buss Wires - Zone heater cables have a series of heater zones. The junction between zones are called NODES. See separate heater cable power and termination kit instructions for information on how to locate node. YOU MUST LOCATE THE FIRST AND LAST NODES TO CORRECTLY INSTALL THIS PRODUCT. Node Zone nodes must also be located when installing splice and tee connections. Do not exceed the maximum circuit length of the heat trace. Refer to the heat trace cut sheet. Only connect bundles of the same model. Insulate the Splice/Tee area to the same physical size. Completely weather seal the area, paying particular attention to the exit points of the tracer. Apply RTV sealant around this area to prevent moisture ingress. See page 9 for sealing product options. Node Zone Length Node When installed, the first node must be a minimum of 6" (150mm) away from the junction box entry gland or the end termination fitting. The heater cable from the cut end to the first node will be unheated. Splice 6" (150mm) Min. Splice Kit 6" (150mm) Min. Node Location Jacket Patch Kit Junction Box Entry Gland Heated Node Location 6" (150mm) Min 6" (150mm) Min End Termination Tee 6" (150mm) Min. Tee Kit 6" (150mm) Min. Allow enough tubing to reach process connections at each end. Bundle length may need to be adjusted to insure that the ends of the tubing are in contact with a heated zone.

8 Minimum Bend Radius Minimum bend radius for all products with 5 /8" (16mm) and smaller diameter tubes is 8" (200mm). Minimum bend radius for all products with 3 /4" (19mm) and larger diameter tubes or 2 1 /2" (65mm) and larger bundle diameter is 12" (300mm). To bend on the other (larger) dimension: Method 1 - Make two back to back bends on small dimension and twist the bundle in the direction you want it to go. Bending The jacket will wrinkle when the bundle is bent. This is a normal condition and does not affect the performance or life of the bundle. Applying silicone spray on the bundle jacket will help the bundle slide in the mandrel, especially in cold temperatures. Bend on the small dimension. The bundle will tend to twist and then bend on this dimension naturally. Method 1 - Use O'Brien BB8 or BB12 bundle bending tool. Method 2 - Grasp the bundle firmly and twist it 90. Then make the bend. This technique may also be used to position the tubing for process connection. Method 2 - Use mandrel or spool hub with minimum or larger diameter hub. 8

9 Vertical Runs Two methods are used, one pulls the probe or process end of the bundle into place and the other lifts the product spool to the highest point and lowers the instrument or analyzer end. Lowering Bundle from Top Down If the bundle has factory finished ends or factory installed temperature sensors the probe and power ends will be labeled on the bundle.
