General Safety Information
Read this manual carefully before beginning the installation and operation of the unit.
Scan the QR Code below to view the Basic Walk-In Installation Service Video.
Special attention is required to all sections identified with the following warning and
caution notices:
WARNING
Text in a Warning box alerts you to a potential personal injury situation. Read each
Warning statement before proceeding and work carefully.
CAUTION
Text in a Caution box alerts you to a situation in which you could damage the unit. Read
each Caution statement before proceeding and work carefully.
Disregarding these special notices may result in personal injury and/or damage to the
unit.
Safety Notices:
Installation and maintenance/servicing are to be performed only by trained and
qualified personnel familiar with commercial walk-in products.
Ensure that all field wiring conforms to the equipment requirements and all
applicable local and national codes.
Disconnect all power sources before servicing the unit.

Receiving Inspection
Check the shipment carefully and compare to the bill of lading. Account for all items
listed and inspect each container for damage. Carefully inspect for any concealed
damage. Report any shortages or damages to the carrier, note on the bill of lading, and
file a freight claim.
Damaged material cannot be returned to the manufacturer without prior approval. A
Return Material Authorization (RMA) must be obtained. Contact a sales representative
at 800-826-7036.
Panel Count and Hardware
Using the packing list and skid documentation, count the wall panels, corners, ceilings,
doors, and floors where applicable. Locate and verify the accessory and hardware
package(s).
WARNING
Do not attempt to lift the panels or accessories by yourself. Always have adequate
lifting equipment or manpower available to accomplish the task safely.
Do not unwrap the skids and leave the panels in a position that they could fall over or
blow over and cause an injury. Be sure that panels are adequately restrained at all
times.
CAUTION
Acids and oils on hands and fingers could discolor wall panel finish. Make sure to wear
appropriate gloves that are free from residue while handling wall and ceiling panels.
CAUTION
Make sure to store the panels as noted below if necessary to ensure that they are not
damaged prior to being installed.
Panel Storage
If the walk-in panels must be stored on a job site before installation, store them inside if
possible.
The PVC protective panel covering should only be removed after final assembly of the
walk-in. Gloves should be worn to prevent acids and oils on hands/fingers from creating
smudges on panel surface.
The panels may be stored on skids as received, provided the skids are on level surface
and kept free of moisture.

If the panels must be stored outside, store them on edge with the grooved side (female
rail) facing down. Kiln-dried wood spacers provide a ventilation gap to prevent moisture
stains from forming on the panels’ metal skins. Cover the panels with black plastic to
keep out sunlight and moisture. Be sure the plastic does not touch the ground, allowing
air circulation.
Panel identification
Each panel is labeled to aid in identification and proper placement. Panel item numbers
are referenced on the product assembly drawing showing proper location for intended
installation within the unit.

Site Preparation
CAUTION
Ensure that the area for installation is level and clear of all debris before beginning
assembly. If care is not taken to assure a level base, wall and ceiling panels will not
align properly, causing problems in installation and operation of door panels, and
potential performance issues due to escessive air leaks. The two recommended
techniques to level the floor area are self-leveling epoxy and/or asphalt shingles.
For concrete slabs, above grade is recommended. A slab below grade is not permitted.
A 2” minimum clearance is required between the unit and any adjacent structures to
allow for wall surface irregularities and for air circulation. Air circulation around the
walk-in of 5 CFM per 100 Sq. Ft. of wall area is recommended. Failure to allow for this
clearance and air flow may result in performance issues such as excesive moisture
and/or condensation in the unit or adjoining areas.
Using the supplied assembly drawing (in hardware box), mark the perimeter of
screed, wall, or floor sections on the existing building floor using a chalk line.
Perimeter lines must be square and parallel. Use the 3, 4, 5 rule of squaring.
After the first two lines, measure and establish the rest of the perimeter.

www.kolpak.com 800-225-9916 7
If the installation area is not level, find the high point of this perimeter line. The
floor, floor screed and wall must be leveled to this point.
Use a 4’ level to determine floor levelness. Be sure to check both directions for
floor levelness.
Cam Action Panel Fasteners
Before starting to assemble the unit, be sure to familiarize yourself with the operation of
the panel fasteners.
To operate the cam locks, insert a 5/16” hex wrench (packed in hardware box)
through the access hole in the panel interior skin, and into the hex opening in the
fastener. Turn the wrench clockwise approximately 3/4 of a turn to put the cam
hook into the locked position.
If a problem should occur, such as having to unlock a panel that was not properly
positioned, you must turn the handle counterclockwise until it stops, in order to
reset the cam position.

Scan the QR Code below to view Operating The Cam Lock Service Video.
CAUTION
Using a hammer to drive the hex wrench into the panel fastener can result in damaging
the interface surface, rendering the lock unusable. Clear the hole of any debris if the
wrench cannot be fully inserted with normal hand pressure.
General Installation Guidelines
All insulated panels have a tongue and a groove perimeter edge. This interlocking
design and the panel edge gaskets will result in an air-tight walk-in when installed
square and level. Refer to the assembly drawing for the general layout and specific
panel placement and markings.
The tongue side of the panel and cam lock holes is on the left of each seam when
viewed from the interior of the walk-in (standing on the inside and looking out). The
exact location of the tongue (M) and groove (F) for ceiling and floor panels, if required,
will be shown on the assembly drawing.

Screed Identification And Installation
There are many styles of screeds used in floorless walk-in coolers and freezers. The
types of screeds furnished with your unit will be identified on the unit assembly drawing.
Breaker strips (thermal breaks) are used to prevent heat transfer between the
cooled side and the ambient side of a concrete floor. Without these thermal
barriers, heat transfer through the concrete layer is relatively rapid, causing a
greater likelihood of condensation and icing outside of the unit, as well as
increased energy consumption and cooling load on the refrigeration system.
CAUTION
When having a product installed with a thermal break, make sure that the contractor
leaves the top of the thermal break exposed for later inspection, not covered by
concrete. If there are performance issues after installation, it may be necessary to
inspect the position and condition of the thermal break.
Standard screeds are available in both vinyl (with integral floor coves) and metal
versions. Vinyl screeds cannot be used in outdoor applications due to potential
issues with UV degradation caused by sunlight. Most thermal breaks are
installed to be level with the concrete surface. Heights for vinyl screeds are 1.5”
or 4”, while metal screeds are available in various heights as necessary for the
application. Standard screeds are pre-cut with intended installation locations
shown on the assembly drawing.

www.kolpak.com 800-225-9916 10
U-shaped screeds are available for customers who desire to use a vinyl screed,
but need either a lower profile or need a special height finished unit, and would
prefer to use a standard sized wall panels. U-shaped screeds are factory cut to
length and mitered on the corners, with intended installation locations shown on
the assembly drawing.
Flat-bottom walls are available for configurations that require a metal screed, do
not have an integral cove, and will be anchored by an exterior (or interior)
mounting angle. Mounting angles are supplied in 10’ lengths and field cut to fit
the dimensions of the enclosure as necessary.
Screed Installation
Place the screeds on the floor using the chalk lines as guides. Where factory cut
screed is used, screed sizes and layout are identified in the assembly drawings.
