Congratulations! You have purchased a brand new W.A. Brown & Son, Inc. Walk-In Cooler or Freezer. To ensure
proper set-up and many years of trouble free use, read and follow these instructions carefully before and during
installation. This manual covers the basic installation of a standard walk-in. See sheets enclosed with shipment for
installation instructions for items not covered in this manual.
If You Have Freight Damage:
Brown walk-ins are shipped on pallets with shrink wrap, in dedicated trucks or in specially marked and designated
cartons. These methods have been chosen to decrease the possibility of freight damage; however, each shipment
should be inspected for exterior damage. If damage is found, please note it on the delivery freight bill and call
W. A. Brown Customer Service. Under NO conditions may a damaged unit be returned to W. A. Brown & Son, Inc.
without first obtaining permission.
Checklist Suggestions:
Read and understand the installation manual and cooler drawings before attempting to install the walk-in.
Make sure you have the number of pallets or crates listed on the Bill of Lading.

Remove all panels from their shipping cartons and stack them in rows of like panels; wall panels in one
row, ceiling panels in another, etc. Panels with a 6" yellow sticker are non-standard panels and have a
particular location in the walk-in. This number can be found on the drawing identifying the location of these
panels. All standard panels are interchangeable. You do however, have to put the proper size in the proper
location.
The refrigeration should be inspected upon receipt.
Check the shipping list to insure you have the correct number of panels, doors and accessories. If any prob-
lems are found, please contact the factory as soon as possible.
Locate accessories box for buttons, assembly wrench and a drawing.
Panels that have a PVC protective covering on the metal skins should have the PVC removed as the panel is
selected for installation. This will make removal of the PVC easier.
It is recommended to use two people to handle panels. For door sections and larger panels a dolly or pallet jack
may be useful.
If panels must be stored on a job site prior to installation, it is recommended that they be stored inside. Panels
received on skids or in cartons, should be stored as received, provided the skid or carton is on a level
surface and kept free from moisture. If the panels are received without crating, they should be stored on edge
with the female edge of the panel down. (Stacking may cause damage.)
Your door and section will be labeled with an ID# such as 1D, 1D1, 2D, etc. This ID# along with your drawing
will help you locate the door and section in the proper position.

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.

Installation of floor panels
Installation of the floor may begin when the floor leveling is complete. Refer to the floor panel layout drawing which

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.
