d. Secure the top coil assembly by attaching the lifting apparatus to the lifting hook installed on the top coil assembly. e. Remove the coil clamp bands that secures the top coil assembly to the lower coil assembly. f. Carefully, lift and remove the top coil assembly off the lower coils.

Install SE Coil Assembly (See Figure 1.)

a. Prepare the main heating section flange ring surface with a layer of G. S. Tef- lon Thread Sealing Compound. This will aid in adjusting the SE coil assembly into alignment with the main heating section. b. Lift the SE coil assembly up onto the main heating section.

NOTE If desired, the inner heater cover may be installed on the SE coil as- sembly prior to lifting it onto the main heating section.

c. Align the SE coil assembly’s bottom flange ring with the main coil section flange ring. d. Rotate the SE coil assembly, as needed, to align the feedwater inlet(s), as shown in Figure 2 and 3. e. Install the inner clamp bands around the main heating section flange ring and the SE coil assembly’s bottom flange ring. Secure the clamp bands with their attaching hardware. f. Place and align the inner heater cover on SE coil assembly. g. Install the inner heater cover clamp bands around the heater cover and the SE coil assembly’s top flange ring. Secure the clamp bands with their attaching hardware. Install Outer Shells a. Two-piece Outer Shells- Lift the rear outer shell piece (the shell piece with the cut-outs) up around the rear-side of the SE coil assembly and the feedwater inlet/discharge, allowing it to rest on the main outer shell below. Using a set of self-locking clamps, Vise-Grip ® pliers for example, clamp the SE outer shell to the main outer shell. Three-piece Outer Shells- Pre-assemble the front outer shell piece and the left outer shell piece while on the ground. The left outer shell piece consist of two cut-outs in the lower half. Screw the two shell ends opposite the cut-outs together. Lift these assembled outer shells up around the front and left side of
