Layout of the Floor

Floor Preparation and Installation

Installation instructions are provided for walk-ins with insulated floor panels or walk-ins set on spline. Instructions are also provided for the application of walk-ins in areas requiring adherence to wind or seismic loads.

Warning! A level walk-in is essential. If the floor is not level, the vertical panels will not be plumb and the hinged door will not operate properly and panels will not seal properly.

Check the floor plan of the walk-in for the exact location of the floor panels as indicated on the floor panel layout drawing which

is furnished with each walk-in. The building area on which

the walk-in is to be erected should be chalked to the
base of the box. If the walk-in is to be erected
next to an existing wall a 2" clearance should
be allowed for surface irregularity. Set-up
‘Builders Level’ per instructions. Take readings at
selected intervals on a story pole to determine the
highest point of floor assembly. Mark the high point
and shim to this level.	Shim

Shims of 24 to 12 gauge sheet metal or cedar wood are
recommended. Shims should be cut a minimum 4" x 4". Shims	Level
must extend under the whole section, not just the edges. Shims should	Level
be at each end, at all wall seams and at each floor seam. All shims
should be no further than 12" apart. Shimming will reduce load limits. Shims are

not supplied with shipment. An alternate method of leveling is to level the unit by filling in with a level bed of sand. Cover the sand with a poly film or asphalt paper before installing the floor. See Figure #1.

Installation of floor panels

Installation of the floor may begin when the floor leveling is complete. Refer to the floor panel layout drawing which has been furnished with the walk-in. Begin installing the floor with an end panel. Continue until all panels are set and are level. Engage all cam locks as the panels are installed. Recheck levelness of the floor panels after all are complete.

Warning! Position the floor panels per the drawing to ensure that the door will be properly placed. In multiple compartment walk-ins with a partition section, it is imperative that the panels be located in proper position and turned correctly so that walls and tops will lock securely.

Warning! Attention Floor Contractors: Some chemicals and vapors in field applied floor materials can cause metal corrosion. Use extreme care to keep these materials off of metal surfaces and to keep doors open fully and the cooler ventilated until inside flooring is cured.

Diamond Aluminum Treadplate Overlay Instructions

All treadplate material will be cut to size, to match the entire interior surface less 1/2" on all four sides.

1.Clean and dry subsurface

2.Apply silicone to underside of treadplate

3.Begin laying first row of Treadplate Overlay 1/2" away from the edge of the floor according to the Drawing and secure the subsurface with sheet metal screw/anchor.

4.All sheets must be flush as possible with one another.

5.All sheets can be secured using a sheet metal screw every 24".

6.Continue to follow the layout of treadplate according to the drawing until all sheets are flush and secure to the subsurface.

7.Caulk all seams and edges of treadplate layout.

8.Allow 1-3 hours to dry before resuming use of walk-in.
