INSTALLATION
HFP & HFP-E SERIES HEAVY FUEL PREHEATERS
Scope
This document provides step-by-step instructions for installation of HFP (Fig. 1) and HFP-E (Fig. 2) preheaters. HFP models are heated by thermal fluid. HFP-E models are heated electrically. Preheaters are available as stand-alone units or as skid-mounted systems.

Intended users
Instructions in this document are intended for use by qualified installers. Qualified installers include licensed electricians and contractors who can make installations that conform with all local codes.
Use proper lifting lugs
When moving a stand-alone preheater, use its two lifting lugs (A and B, Fig. 3). One is mounted on the coil bundle flange, and the other is on the preheater shell. Do not lift preheater with straps around the shell. Doing so will damage the aluminum skin and the insulation.

When moving a skid-mounted system, use the special lifting lugs designed specifically for lifting the entire skid (A and B, Fig. 4). These special lugs are positioned for even weight distribution when lifting the entire skid. Do not attempt to lift the entire skid by the preheater’s standard lugs (Fig. 3), because the skid would not be evenly balanced and would be difficult to control.
Note: Some skids may have lugs mounted in different locations. Some skids may be fitted with forklift pockets for moving the skid by forklift.
