HEAT SHIELD EXTERNAL INSTALLATION OF REFRIGERATOR INSULATION LINER.
On the outside of the refrigerator box, One inch or 1/2 inch of foam should be applied with epoxy. The epoxy is used to keep moisture from coming through a fiberglass box. The foam is a thermal standoff between the Cold box and the heat shield refrigeration liner insulation. Once the foam has been placed on the box, the Insulation should be cut to go on the box. After cutting out each insulation panel, it should be sealed with material supplied according to instructions supplied. Then the sealed panels should be put onto the foam. This can be done with small areas of double sided tape. It is best to have as little contact surface area as possible between the foam and the inside of the liner. Marine caulk should be used join the inside of the corner joints where panels come together. The outside of joints where panels come together and the heat seal flange overlaps the adjoining panel should be taped across with the silver tape supplied. The silver tape should be used only to tape the outside of one panel to the outside of the next adjoining panel. Once the panels are installed on the foam, the whole refrig should be inserted into the cabinetry in such a manner that it has a free airspace all the way around the outside of all 4 sides and the bottom. This air space should be vented at the upper back and at the lower front to allow passive heat to be removed from the airspace thereby removing excess heat from the liner outer surface. Support for the refrigerator box can be provided by installing small squares of foam pads from the external cabinetry to the outer surface of the liner as long as these 5.
support pads do not constitute more than 6%
of the surface area of the liner and as long as they do not block
the free flow of air. Do not install the liner around the box and
foam the entire outer surface. The foam will build up conducted
heat energy and if compacted against the heat shield material
outer surface will greatly reduce the insulation value. The
bottom and top insulation panels should overlap all 4 side panels
to prevent convection entering side panels from below and prevent
infrared from entering side panels from above if possible.
