SITE SELECTION, BASE PREPARATION
WALK-IN COOLER WITHOUT A fLOOR INSTALLEd ON 1" vINyL SCREEd
IMPORTANT! Do not attempt to erect a floorless walk-in FREEZER on a existing building floor that has
not been specially prepared and adequately insulated for below freezing storage temperatures. Note: All
thermal breaks in floor slab must be exposed, including the partition wall.
To install a vinyl screed assembly on an existing floor, proceed as follows:
Locate the screed (floor sealer) diagram which was packed in the hardware box and, using it as a guide,
draw an outline of the outside dimensions of the installed screed directly onto the building floor where the
walk-in will be situated. These dimensions will be 1 1/2" larger than the overall 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) to allow
for irregularities of the building wall (s) and to permit a free flow of air between the two surfaces.
CAREFULLY CHECK FOR SQUARENESS by insisting that the two dimensions between opposite
corners are equal (Figure 1).
One of the most important procedures that will be encountered in the base preparation is
LEVELING THE SCREED. It must be PERFECTLY LEVEL! If it is not, the wall panels will follow the
irregularities of the building floor which will directly affect subsequent procedures such as panel latching,
panel gasket seal, ceiling panel assembly and others.
After the outline of the screed assembly is completed, locate the highest point within the outline on the
floor where the screed will be installed. Screed sections are 5 1/2" wide. A transit or surveyor's level is an
ideal instrument for this purpose. Mark the highest point on the floor (Figure 2) and, referring to the screed
diagram, identify and locate the appropriate screed section and position it directly over the highest point.
