SITE SELECTION, BASE PREPARATION
WALK-IN COOLER OR fREEZER WITHOUT A fLOOR INSTALLEd ON fOAMEd SEALERS
IMPORTANT! Do not attempt to erect a floorless walk-in FREEZER on an existing building floor that
has not been specially prepared and adequately insulated for below freezing storage temperatures.
To install a foamed sealer (screed) assembly on an existing floor, or on a properly prepared floor
for freezers, proceed as follows:
Locate the floor sealer (screed) diagram that was packed in the hardware box and, using it as a
guide, draw an outline dimensions of the installed sealer (screed) assembly directly onto the building
floor precisely where the walk-in will be situated. These lines will be exactly the same dimensions
as the dimensions of the walk-in in both directions. If the walk-in is to be installed next to an existing
building wall(s), make sure that a MINIMUM OF 2” REMAINS BETWEEN THE DRAWN OUTLINE
AND THE BUILDING WALL(S). This space will allow for irregularities in the building wall(s) and
will permit a free flow air between the two surfaces. CAREFULLY CHECK FOR SQUARENESS by
insisting that the dimensions between opposite corners are equal (Fig. 1).
Since the foamed sealer (screed) is retained in position by a 3/8” thick plywood sealer guide, which
will be secured to the building floor, it is imperative that the sealer guide be accurately located, as
well, on the building floor. Refer to the sealer guide diagram which was also packed in the hardware
box. On the diagram, you will notice that the sealer guide is located 78” INSIDE the drawn outline
which represents the outside dimensions of the sealer (screed) assembly. Further, Fig. 1 illustrates
that the sealer guide is 2 1/4” wide centered beneath a 4” wide sealer leaving a border of 7/8” along
each edge. Draw another outline of the outside dimensions of the sealer guide directly onto the
floor. There should be exactly 7/8” between the new sealer guide outline and the previously drawn
sealer (screed) outline (Fig. 2).
