DO NOT attach the heater body sections together on the ground and attempt to hang the entire system at onetime. The weight of the individual heater body sections can cause misalignment and damage to the heater. 3. Join the body sections together and secure with tube couplings as follows: AWARNING: The following coupling tightening instructions must be followed properly to avoid future problems. a. Place the compression coupling over the end of the tube from one body section, with the tightening bolts located on the bottom and facing the installer. NOTE: There is a small hole at the centerline of the coupling that can be used to sight the end of the tube. b. Partially tighten the bolt nearest the end of the tube (approximately half closed). c. Slide the ends of the tube from the opposite body section into the coupling. Make sure both tube ends are butted together. d. Finish tightening both bolts to 40-60 ft.lbs. torque to ensure a complete seal. e. Check to ensure that the hardware is completely closed and that the band is seated on the reaction block and interference pins as illustrated below. f. Check to see if the reaction block is firmly seated on the tube. g. Self-drilling screws are provided to prevent any possible movement of the tubes from the coupling. Install the screws as shown using an electric or air screwdriver with approximately 2500 rpm speed. Pre-punched holes in the coupling make it easier to install these self-drilling screws. h. Once all the heater body sections are attached, make sure that the heater system is level. If it is not, slight adjustments can be made using the turnbuckles. (See Section 17.) !IMPORTANT: NEVER REUSE A COUPLING. Always install a new coupling only and torque as per Instructions above and the diagrams that follow. Form #43155010 Feb-04 -7- INCORRECT INSTALLATION CORRECT INSTALLATION TUBE COUPLING Self-Drilling Screw (Qty. 2) Tube Support/Hanger Bracket 4. The tube at the coupling joints must be covered. Slide the reflectors together and provide a one-inch overlap. (This will allow for the natural expansion and contraction of the heater when in operation.) Secure reflectors together by sliding speed clips on the reflector joint edges. One speed clip is required for each side of the reflector. Tighten the reflector clamps. !D0 NOT OVER-TIGHTEN! Make sure that the reflector can slide under the clamp during heater operation. 12) ADDING OPTIONAL 90° ELBOW (LTS ONLY) 1. The optional 90° elbow must be located a minimum of 10 ft. after the control box. 2. Hang the body sections in a 90° ("L") shaped pattern. Allow spacing for the elbow. The distance from one end of the elbow to the centerline of the opposite leg is 13" as shown. 3. Join the tube ends of the body sections and the elbow together and secure with tube couplings as described in Section 11. (Optional) 13) ADDING OPTIONAL CORNER REFLECTOR (LTS ONLY) 1. Place the corner reflector over the reflectors of both body sections. ...
