Installation Procedure
Installation Procedure
Step 1: Unpacking.
Move the container to the installation location before removing the protective materials.
If the unit is damaged after opening the container, repack the unit in the original packing material(s). RETAIN ALL PACKING MATERIALS. In general,
freight damage claims will be denied if the original packing materials are not retained for the freight claim adjuster to inspect. Call your supervisor on
shipment.
1. Before opening the packaging, inspect it for damage.
2. Remove the protective cardboard and top sheet and place to the side.
3. Remove the electric preheater from the shipping carton and inspect the box for freight damage.
4. Place the box right side up on a solid level surface.
5. Check the unit nameplate data and model number. Verify that it matches the label on the box and the submittal data.
6. Locate and retain the installation manual.
Step 2: Location Selection (Remote Mounted Installations Only).
If the electric preheater is to be installed in a remote location where it is not directly connected to the LG Compact DOAS unit, choose a
location that conforms to the following:
Dos
• The structure will support the weight of the electric preheater.
• The structure allows the electric preheater to be easily hung in a level position.
• The structure provides proper clearance for removing and inserting filters.
Don't
Step 3: Apply Duct Sealant.
Apply duct sealant on the outer side of four (4) flanges cross-
hatched in the figure at right before attaching the electric preheater
to the inlet of the LG Compact DOAS unit.
