Specifications
GENERAL
Walk-ins shall be constructed of prefab, precision-formed, modular panels designed for accurate, rapid field assembly. Walk-ins shall be test assembled at the
factory. Walk-ins shall be equal to those
manufactured by U.S. Cooler.
DRAWINGS AND INSTRUCTIONS
Each walk-in shall have a set of installation
instructions and lay-out drawing. All
panels shall have panel identification
corresponding with the lay-out drawing to
facilitate rapid and accurate field erection.
PANEL CONSTRUCTION
Each panel shall consist of inner and outer
metal skins, a 4" insulation core, and be
equipped with cam-action locking devices.
The locking devices shall be operable from
inside the walk-in and a hex-shaped
wrench shall be supplied. Press-fit plug
buttons shall be provided to seal wrench
holes after assembly is complete.
Construction shall be as approved by the
National Sanitation Foundation
International and shall bear the NSF®
Seal of Approval.
All panels shall be connected to one
another by placing the tongue of the
insulation core of one panel into the groove
of the core insulation of the adjacent panel.
The resultant tongue and groove joint shall
be sealed at both sides by double barreled
NSF® approved gaskets. In order to avoid
future swelling and mold formation, no
wood shall be permitted in the manufacture
of the tongue and groove panel profile.
PARTITIONS
When specified, walk-ins shall be divided
into compartments by the use of panels
that are constructed in accordance with the
specifications for all panels.
FLOOR SCREEDS
Floor screeds shall be provided for all
floorless walk-ins. The screeds shall be
vinyl, and have NSF® approved cove both
inside and out.

CFC free process, made from 60%
recycled materials and 100% recyclable.
Door insulation may be Polyurethane.
Coolers
Extruded Polystyrene: All wall and ceiling
insulation shall be 4” thick, high quality,
rigid extruded polystyrene, 1.6 lb density. K
factor of not more than .139 and an Rfactor
of not less than 7.2 per inch, initial
fresh R-28.8 minimum total wall R factor.
Vapor transmission shall be less than 1
perm and foam core material must meet
UL 5 flame spread rating with average
smoke rating less than 165. (UL 723)(UL 723)
Freezers
All wall and ceiling insulation shall be
4" thick, high quality, rigid Extruded
Polystyrene, 1.6 lb. density. K factor of not
more than .125 and an R factor of no less
than 8 per inch, initial fresh R-32 minimum
total walls R factor. Vapor transmission
shall be less than 1 perm and foam core
material must meet UL 5 flame spread
rating with average smoke rating less
than 165. (UL 723)
PASSAGE DOORS
(Standard door is 34"x76"; alternate sizes are available upon request).
Cooler Doors
Door shall be flush mounted, positioned and hinged per drawings. Doors shall be provided with suitable sweep and magnetic gaskets. Door shall be provided with door closer, one pre-wired vapor proof light fixture, light switch with pilot light, dial thermometer, manual internal lock override, chrome plated can lift hinges, and chrome plated door latches with strike. Doors on outdoor walk-ins shall have weather protected light switch and door drip cap.
Freezer Doors
Freezer doors shall be identical to coolers doors, but with the addition of UL approved heater wire on all four sides. Freezer doors shall include a heated pressure relief port in the adjacent panel.

Membrane material shall be provided in one complete roll designed for the size of the walk-in. No welding of seams shall be required for installation.
SLOPED ROOF PACKAGE
(When specified)
(For use on walk-ins installed outside) (May be required at certain snow loads; consult U.S. Cooler)
In order to form a sloped roof profile,
suitable quantities of sloped foam shall be
provided. The foam shall be cut in a
manner that upon installation, a ¼":1' slope
is obtained. The membrane roof shall be
increased in size appropriately, in order to
