FOAM PANEL STORAGE

If foam walk-in panels require storage at the job site prior to installation, the following steps must be taken to
protect the panels against both staining from moisture and sunlight, and denting by workers and traffic.

Whenever possible, the panels should be stored indoors, and should remain in the crating pallet they were
originally shipped in. If the panels were uncrated as they were unloaded from the delivery truck, and they are being
stored indoors, they should be stored vertically on skids with spacers between the panels.

When storing panels in a vertical position, always place the female rail (grooved) edge down (see illustration
below.) This method of storing panels will provide proper ventilation, permit drain-off of condensation moisture
and protect panels against the formation of white rust stains.

If the panels must be stored outdoors, follow the same procedure as indicated for indoor storage WITH THIS
ADDITION: Cover the panels completely with an opaque polyethylene water-proof material to protect against rain,
snow, heat and sunlight.

The illustration below shows the method for storage outdoors when panels are not left in palletized crates.

ERECTION DIAGRAM

The erection diagram, as furnished with each walk-in, is a
detailed plan that illustrates the placement of every wall, corner,
ceiling and floor panel that comprises a complete, individual
walk-in.

The erection diagram for all installations clearly shows the
direction of the male and female formed profile of every wall
panel and every corner panel.

Erection Diagram

All sections used to construct your walk-in are marked with
a specific part number on the section, corresponding with its
location on the erection diagram.

If the walk-in is floorless, then a diagram showing the vinyl
screed (floor sealer) arrangement is provided.

The vinyl screed combines the capability of retaining the wall
panels in place while providing the inner and outer cove at the
junction of the walls and the building floor (a requirement
of Standard No. 7 of the National Sanitation Foundation
(NSF).

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!

SECTION LATCHES

All wall, corner, ceiling and floor panels are joined and locked together by the
mechanical action of section latches which are integrally foamed into the panels
near the perimeter edges. A section latch consists of two halves – a lock housing
which contains a cam actuated locking arm, or hook, and a strike housing which
contains the engagement pin. Both housing halves are securely anchored in the
foam core of the panel. The lock housing is always located in the male-formed
edge and the strike housing will be found in the female-formed edge of the panel.

TO OPERATE LATCHES

secTion laTches

• Fully extended cam lock

Hex wrench provided in

1. Insert the hex wrench
(packed in the hardware
bag) through the access
hole in the interior
panel metal into the hex
opening of the section
latch. Turn wrench in
a counterclockwise
direction to ensure
that the lock is fully
unlatched

2. Push the sections
tightly together and turn
the wrench 1/4 turn in a
clockwise direction. This
will engage the locking
arm (hook) over the pin in
the strike housing.

3. Continue turning the
wrench to a full stop
(approximately 3/4 of a
complete turn from the
unlatched position) to
complete the locking
operation.

Latches on some panels
will have to be turned
counterclockwise to
activate the locking cam.
These latches will be
designated by a "TURN"

SITE SELECTION, BASE PREPARATION & LEVELING THE FLOOR
WALK-IN COOLER OR FREEZER WITH A FLOOR

One of the most important considerations in the erection of a walk-in cooler or freezer is the building floor or the surface
upon which the walk-in will rest. As with any structure, a firm and level foundation is essential to achieve a perfect
end result. If the surface is not perfectly level and smooth, appropriate steps must be taken to provide the proper
base. The positive
action of self-closing
doors, proper door
gasket seal and
condensate removal
all depend directly
upon the level and
plumb installation of
all panels.

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 WALK-IN 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.

NOTE: Indoor walk-in(s) must be in an environmentally controlled
space. Relative humidity should be kept between 30% - 60%,
maintaining a dew point of 50°F or less.

In some cases, the surface upon which the walk-in is to be installed
was especially prepared for installation and it is perfectly level and
smooth. The walk-in floor, in this case, may be installed without
further preparation. Before beginning, however, an appropriate
vapor barrier should be placed over the surface that the walk-in
will occupy. Asphalt felt paper (50#) or a 6 mil polyethylene film,
are suggested materials. These are provided by the installing

contractor.

FLOOR INSTALLATION (Shim Leveling Method)
For walk-ins subject to light to moderate loads

Locate the highest point within the perimeter lines. A transit or surveyor’s level or rotary laser level is an ideal
instrument to use for locating this point. When the highest point is
located, mark it directly on the floor and refer to the erection diagram
to determine where the high point is located with respect to the walk­in floor plan.

One of the most important procedures that will be encountered in
the erection of a walk-in with a floor is LEVELING THE FLOOR.
It must be PERFECTLY LEVEL! If it is not, the wall panel will
follow the irregularities of the walk-in floor which will directly affect
subsequent procedures such as latching, panel gasket seal, ceiling
panel assembly among others.

Using the erection diagram as a guide, select the floor panel that
will be located directly over the highest point and place it in that position while observing the drawn outline on the
building floor.

After the first floor
panel is positioned,
it must be properly
leveled. To achieve
this, shimming material
of varying thicknesses
must be used. Cedar
building shingles are
ideally suited for this
procedure.

IMPORTANT! EVERY
FLOOR PANEL MUST
BE SUPPORTED ON
ALL FOUR SIDES
AND THE ENTIRE
UNDERSIDE, AT
LEAST EVERY 12"
BY EITHER THE
BUILDING FLOOR
OR BY SHIMMING.

After the first floor
panel has been leveled perfectly, trim away the excess shim material so that none projects from the panel at any of
the four edges.

From the erection diagram, determine which floor panel will be installed next and where it will be situated on the floor
plan. Prepare shimming material for the second panel at each point where shimming material was used beneath the
first floor panel. The shimming material thickness must be such that it will support the
second floor panel at exactly the same height as the first panel along the entire length of the joint. NOTE: In many
cases, the shimming material will be the same thickness as the adjacent shimming under the first panel.

1/10 Rev. B 132617

flooR insTallaTion (shim levelinG meThod)

Place the second panel in position next to the first floor panel but

DO NOT LOCK!

Shim the second panel, where necessary, using the same procedure
as was used on the first panel. When all four edges of the second
floor panel are properly shimmed, lock the two panels securely
together. Using the same technique for leveling, check the levelness
of the two sections in all directions by placing the level across the
joint at several points and, again, check the levelness of the floor
panels in the direction of the panel joint.

Refer to the erection diagram and install the remainder of the floor
panels using the same procedure as was used for the first and
second floor panels. When all of the floor panels are installed and
leveled perfectly, check the section latches for full and complete
locking.

Trim excess vapor barrier.

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.
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.

Figure 3

After the first screed section is positioned, it must be LEVELED PERFECTLY not only over its length but,
across its width, as well. To achieve this, shimming material will probably be required. Vinyl floor tile is
ideally suited for this purpose. IMPORTANT! EVERY SECTION OF SCREED MUST BE SUPPORTED
AT LEAST EVERY 12’’ BY EITHER THE BUILDING FLOOR OR BY SHIMMING (Figure 3).

Assuming that the first screed section has been perfectly leveled, refer to the screed diagram and select an
adjoining screed section and level it perfectly in both directions, shimming wherever necessary. Continue
leveling the remainder of the screed sections until the entire assembly is in position. Check the assembly
to make sure that the outer edges are located exactly on the drawn outline on the building floor.

12

1/10 Rev. B 132617

Walk-in insTallaTion - siTe selecTion, Base PRePaRaTion

When the entire screed assembly is leveled and supported by shimming, as required,
CAREFULLY AND WITHOUT DISTURBING THE SHIMMING MATERIAL, lift the screed sections, tip
them upside-down and apply a heavy bead of construction sealant to the bottom of the screed section
along both of the edges that contact the building floor surface. The diameter of the sealant bead should
be larger than the thickest shimming material to ensure a complete, air-tight seal along the entire length
of the screed (Figure 4). NSF approved sealant is provided and will be found in the hardware box.

Immediately after applying the construction sealant to a screed section, replace the screed section to its
original location on the building floor WITHOUT DISTURBING THE SHIMMING MATERIAL and place a
sealer splice every joint in the screed assembly (Figure 4). Since the sealer splice is intended to keep
adjacent screed sections in alignment, approximately one-half of the sealer splice should lap each section.
It need not be fastened in place (Figure 4). NOTE: Seal all screed joints with sealant. Make a final
check for squareness, levelness and whether the screed assembly is located properly with respect to the
drawn outline on the building floor.

Follow by securing the screed assembly to the building floor with fasteners that are appropriate for the
building floor. These fasteners are not provided and must be obtained by others.

Fasteners should be applied down the center line of the inside of the screed at intervals of approximately
36’’; however, where shimming is used, apply the fasteners through the shimming material, NOT BETWEEN
the shimming. When the entire assembly is secured in position, trim away all excess construction sealant
and shimming on both edges of the screed. Trim flush with the sealant lip of the screed and touch up any
areas where the construction sealant is not making a perfect seal (Figure 4).

NOTE: In the event that the building floor was specially prepared for the installation and no low or high
points are detectable, it is possible that no shimming will be necessary. It will then only be necessary to
apply construction sealant to the bottom of the screed and secure the screed directly to the building floor.
The entire procedure, as described, must be followed explicitly, however, except for the details that pertain
to the shimming.

ALTERNATE SHIMMING METHOD FOR 1’’ VINYL SCREED

If the surface that the vinyl screed will occupy is level, except for an occasional low point, the screed
may be secured directly to the building floor and compensation for the low points may be achieved by
shimming the support shoulders on the inside of the screed.

When employing this method, the low points should be marked on the building floor in the vicinity of the
drawn outline for reference. After the screed has been sealed and secured, leveling may proceed with
special attention being focused in the areas marked as being low points.

Vinyl floor tile is often chosen as shimming material and strips (5/8’’ wide maximum) are cut and placed
on top the supporting shoulders of the screed to provide a level surface for the wall sections to rest upon.
Strips of tape should be applied to hold the shimming material in place (Figure 5).

IMPORTANT! Shimming the support shoulders on the inside of the screed is ideally suited
for minor irregularities on the building floor and has the advantage of complete screed-to-floor
contact over the entire perimeter of the assembly. IT IS NOT RECOMMENDED, HOWEVER,
FOR EXTREMELY IRREGULAR BUILDING FLOORS. Excessively thick shimming material on the
support shoulders may elevate the wall panels to a point where the effectiveness of the uppermost screed
sealing flanges would be compromised. Shimming thickness of more than 3/4’’ should be avoided! If
shimming the support shoulders of the screed is selected, the entire procedure, as described, must be
followed explicitly to ensure squareness and levelness over the entire screed assembly.

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).

One of the most important procedures that will be
encountered in the base preparation is LEVELING
THE SEALER (SCREED). It must be PERFECTLY

the screed (sealer) will be installed. (Sealer sections
are 4” wide). A transit or surveryor’s level is an ideal
instrument for this purpose. Mark the highest point
on the floor as illustrated on Figure 3.

After the outline of the sealer (screed) and the sealer
guide is completed, as shown in Figure 2, locate the
highest point within the outline on the floor where

16

1/10 Rev. B 132617

Walk-in insTallaTion - siTe selecTion, Base PRePaRaTion

SEALER GUIDE INSTALLATION

Locate the SEALER GUIDES. They are bundled
together and packed along with the walk-in corner
or wall panels and are labeled accordingly. Sealer
guides are strips of 3/8” plywood 2 1/4” wide as
shown in Figure 1.

Refer to the SEALER GUIDE DIAGRAM. Select
the proper sealer guides and position them as
shown by the circled letters on the diagram. Each
length of sealer guide is marked with a circled
letter that corresponds to the circled letters on the
sealer guide diagram.

Each sealer guide, when positioned properly, will
have its outer edge precisely over the INSIDE
OUTLINE drawn on the building floor, Figure 2,
and its outer edge will be exactly 7/8” from the
outline which represents the foamed sealer outer
edge. The quality of workmanship performed in
locating and securing the sealer guides will be
transmitted directly to the location of the foamed
sealers (screeds) and, subsequently, to the overall
erection of the complete walk-in. BE EXACT! Refer
to Figure 1 and Figure 2.

When all sealer guides are in position, make a
final CHECK FOR SQUARENESS and secure
them to the building floor with fasteners that
are appropriate for the surface. NOTE: If the
sealer guide is positioned over a polystyrene
or polyurethane thermal breaker, a compatible
construction adhesive may be used.

FOAMED SEALER (Screed) INSTALLATION

Refer to the FOAMED SEALER DIAGRAM.
Identify and locate the sealer section that will be
positioned directly over the highest point which
was determined earlier and marked on the building
floor (Figure 3).

NOTE: All foamed sealers are male-formed on
one end and female formed on the opposite end.
The configuration of the ends is clearly indicated
on the diagram. Also, make certain that the strike
housing portion of the section latches is visible on
the upper edge of the sealer when it is in position
(see Figure 1 and Figure 2).

1/10 Rev. B 132617

Walk-in insTallaTion - siTe selecTion, Base PRePaRaTion

Figure 5

After the first sealer (screed) section is positioned over the sealer guide and over the highest point, it
must be LEVELED PERFECTLY not only over its length but, across its width, as well. to achieve this,
shimming material will probably be required. Vinyl floor tile cut in strips 7/8” wide by 6” long make ideal
shimming strips that can be placed beneath the sealer, wherever necessary, to achieve levelness.

IMPORTANT: EVERY SECTION OF SEALER (SCREED) MUST BE SUPPORTED AT LEAST EVERY
24” BY EITHER THE BUILDING FLOOR OR BY SHIMMING. Avoid using shimming strips less that 6”
long whenever possible (see Figure 4).

Assuming that the first sealer (screed) section has been perfectly leveled, refer to the sealer diagram
and select an adjoining sealer section and level it perfectly in both directions, shimming wherever
necessary. NOTE: Sealer (screed) sections 8” high or more employ section latches for end-to-end
locking. CAREFULLY flush the upper edges and the inner or outer surfaces of adjoining sealer sections
while locking them together (Figure 5). Continue leveling the remainder of the sealer sections until the
entire assembly is in position.

When the entire sealer assembly is leveled, apply NSF approved sealant to achieve a vapor seal
between the bottom edge of the sealer and the building floor. This sealant is provided and is packed in
the hardware box. The sealant must be applied to the inner and outer surfaces of the sealer (screed)
assembly. Make certain that the sealant produces a complete, air-tight seal, without gaps, and that
special care is taken to seal the shimming material appropriately.

After the sealant has had an opportunity to set up, trim away all excess material flush with the edges
of the sealer (screed) assembly and touch up any areas where the sealant is not making a perfect seal
(Figure 5.).

WALK-IN INSTALLATION
Wall & Ceiling Panel Erection

The installation instructions that follow apply to any walk-in cooler or
freezer where the wall panels are supported either by foamed walk-in
floor panels or by a floor sealer (screed) assembly which has been
accurately located and properly leveled. NOTE: The procedure for
erecting wall and ceiling panels will be identical in all cases. NOTE:
The walls do not lock to vinyl sealers, but will lock to foam sealers when
used.

To aid in the erection process, the floor plan furnished with your walk-in
has part numbers listed for each wall, corner, ceiling and floor section.
Match the part number on the floor plan to the label on the interior of
each panel to determine the current placement for each panel.

Notice, also, that the section latch access holes on the vertical edge of
the panel are always on the interior of the panel.

Position the corner panel in the
proper location on the walk-in
floor or vinyl screed assembly
and, IF THE WALK-IN HAS A
FLOOR, flush the corner panel
with the corner of the floor panel
in both directions and lock it
securely to the floor panel.

Select the first panel to be installed,
normally begin with a CORNER PANEL.
Notice that the panel is labeled "Top"
along with a part number indicating that
when the panel is in its proper position,
the labeled end will be up.

Walk-in insTallaTion -Wall & ceilinG Panel eRecTion

If the first corner panel is supported by a 1" vinyl
sealer (screed), seek assistance to support the
corner panel in a vertical position until succeeding
wall panels are installed. Wall and corner panels
do not lock to the vinyl sealer (screed).

Select the next panel as indicated on the floor
plan and position it on the floor or sealer (screed)
close enough to the first panel installed so that
section latch engagement is possible.

Making sure that the two panels are perfectly
aligned at the TOP EDGE and that the VERTICAL
JOINT of the two panels are perfectly flush, turn
the section latches on the vertical edge of the panel until they are completely
engaged.

IMPORTANT! Insist that the top edges of the adjoining panels are aligned
perfectly.

If misalignment is encountered, merely lift the lowest panel edge while
locking to achieve alignment and, when all latches are engaged, permit the
locked panels to resume their normal position on the walk-in floor or sealer
(screed).

DO NOT SHORT-CUT! TAKE ENOUGH TIME TO PROPERLY ALIGN ALL
SECTIONS.

Walk-in insTallaTion -Wall & ceilinG Panel eRecTion

As each wall panel or corner panel is erected and locked in an
adjoining panel along the vertical joint, engage the section latches to
the floor panels by turning the hex locking wrench ONLY ABOUT 1/4
TURN CLOCKWISE.

Make certain that the wall or corner panel is perfectly aligned with the
floor panel or foamed sealer
before engaging the section
latches.

Continue erecting panels
according to the part numbers shown
on the floor plan, and follow, explicitly,
the technique described for panel
alignment.

CEILING PANELS will be erected at
specific intervals to facilitate the
installation. The intermittent ceiling
panel erection is scheduled to allow the
ceiling panels to serve as supporting
ties between opposite walls as the
installation progresses. CAUTION!
DO NOT SLIDE CEILING PANELS INTO POSITION! To avoid gasket damage,
elevate the ceiling section clear of the wall section while bringing it into position.

When adjoining ceiling panels are in position,
adjust the exterior edges so that they are
perfectly flush with one another and with the
wall panels directly below them. Lock the
ceiling panels securely to each other. DO NO
LOCK ceiling panels to wall panels at this time.

NOTE: If local conditions, such as existing
building walls, make it difficult to align ceiling
panels with each other from the exterior, locate
a step ladder near the interior walls to visually
inspect the alignment and adjust as necessary.

DOOR/DOOR SECTION

A standard door/door section consists basically of a single wall panel that
contains an entrance door and several accessories. The electrical
components contained in this panel were prewired at the factory. They
include the anti-condensate door opening heater, the pilot light, and switch
and a vapor proof interior light.

The door was factory installed on the door panel framing fixture, checked for
squareness and for proper operation under controlled conditions.

CAUTION! While installing the door/door section, extreme care must be
taken to avoid twisting the panel or handling the assembly in such a manner
that it is not square when it is installed. The self-closing feature, door closure
operation and a perfect gasket seal all depend a great deal upon a SQUARE
and PLUMB door/door section.

After all the wall and door panels have been erected and locked securely
together and all the ceiling panels have been positioned above the wall panels,
the ceiling panels have been locked securely to each other, re-check the
position of the ceiling panels with respect to the wall panels.

Now lock all ceiling panels securely to the wall panels.

Recheck the position of the wall panels with respect to the floor panels and
lock them securely together.

NOTE: When a 1" vinyl floor sealer (screed) is used, no attachment to the
wall panels is required.
