Receiving and Uncrating 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.
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.
Cam Lock Installation All panels are connected with a mechanical Cam lock which is activated by using a hex wrench (included with your shipment). There are both a male section, and a female section. The locks are foamed in place and securely anchored to provide a solid connection, when the locking arm is tightened around the locking pin which is located in the female section. To operate the latch, insert the wrench through the access hole which is located on the inside of each panel.
Installation of floor panels secured for seismic and wind - exterior applications After the floor is installed per the instructions above, obtain the hardware and tools for the application of “Tapcon” anchors. 1. 1/4" “Tapcon” Phillips flat head anchors or equal 2. “Tapcon” drill bit; 3/16" x 6 1/2" (No. 790-1036 or equal) Drill through the female cam lock located in the floor panel into the concrete pad to a depth of 2" or more to insure the anchor does not bottom out.
Wall Panel Installation See separate instructions for installation if box has multiple compartments (page 6-7) with a “Tee” panel. 1. Start installation at the corner panel nearest the door or, if cooler is to be installed in a corner, start with the corner located on the inside. (See Figure 7) Place the first corner panel into position. Be sure the ‘arrow’ is pointed up and the male tongue of the panel (edge w/cam locks) is on the right side when standing inside the walk-in. 2.
Top Panel Installation Standard Walk-In: Begin installation of top panels at either end. 1. Check the drawing sent with the walk-in and assemble the top as indicated on this drawing. See Figure #8 for typical top layout. 2. Do not lock the top panels to the wall panels until all panels are positioned and aligned. If top is too large to shift (on larger boxes), go ahead and align, then lock.
3. 4. 5. 6. After the floor panels are installed and level, erect the partition wall panels. After this the partition wall can be set in place and locked. Position the remaining wall panels and lock them all down. The top panels should be installed with the “Tee” Section first, then work toward the ends until all the tops are installed. 7. The combination walk-in must be level and square. Use the same methods as mentioned earlier in this manual.
• • • • Repeat this procedure on all four sides. Trim extra material prior to sealing. Cut, fold, and glue roof membrane using contact cement (not provided) Position flashing to corner and form to fit by applying hand pressure to outside edges. Secure the corner flashing to the sidewalls. Install to existing wall • Allow membrane to extend up the existing wall approximately 6". • Position 2 1/2" cove and fasten. Apply contact cement or caulk (not provided by W. A.
Fiber Cement Finish Panels Installation Fiber Cement panels are available in vertical siding and smooth styles. Smooth Fiber Cement is designed to have a Stucco finish applied in the field or to be painted. Vertical siding style is meant to be field painted to more closely match existing construction. See instructions below on painting Fiber Cement. Inspect all panels as outlined on page 1. All door sections and Buck Openings on Fiber Cement Walk-Ins are constructed using W.A.
Top Panel Installation Indoor walk-ins with dimensions of more than 15' 5" in both length and width (Figure #11) must have some type support for ceiling panels. Exterior beams, interior beams or column supports can be used. In these cases, it is imperative to properly install the rod assembly provided to properly support the ceiling panels and keep them from sagging. Failure to do so may result in an unsatisfactory installation.
Top Panel Trim Installation Installation of 1/2" x 5" Trim on Top Panels • Trim is used to finish off all Walk-In Cooler and Freezers other than Drop-Off units and is left to the installer, as not all field conditions are identical. Trim is packed with each shipment (as required) from W. A. Brown. • Install corner trim pieces first. Use four #6 self tapping screws supplied (See Figure 13-1). Install trim metal between corners. Overlap all joints by 1/2". Use one screw every 2' (See Figure 13-2).
EZ Pack Installation Instructions (See Installation Guide taped to top of each unit.) Installing the Refrigeration System A qualified technician should install the refrigeration. Contact the dealer from who you purchased your Walk-In for a qualified technician. Carefully raise refrigeration system to top of walk-in. Insert projecting sleeve of evaporator box in to cut out of panel. Install louvered grill on interior side of top panel. Grill should be installed with fan motors.
