Warnings and Cautions
We provide many important safety messages in this manual about your Walk-In. Always read and obey all safety messages.
This is the safety alert symbol.
This symbol alerts you to potential hazards that can kill, injure, or damage equipment.
All safety messages will follow the safety alert symbol and either the word “Warning” or “Caution.”
These words mean:
WARNING You can be killed or seriously injured if you don’t follow instructions.
CAUTION Equipment can be damaged or destroyed if you don’t follow instructions.
Important Safety Instruction—Read Prior to Installation
All safety messages will tell you how to proceed to reduce the chance of death, injury, or damage to the Walk-In.
To reduce the risk of re, electrical shock, injury, death, or damage when installing or repairing a Walk-In, follow basic
precautions, including the following:
WARNING: During installation, make sure that
equipment does not exceed oor rating. Note that oor
rating might be less than nished product rating until oor
installation is complete (for example, until wear surface is eld
installed). Plywood sheeting should be used to spread the load.
WARNING: Remove children and unnecessary adults
from the area when installing or servicing the Walk-In.
WARNING: Panel lifting methods and panel lifting
equipment must meet OSHA approved guidelines for the
designed loads and lifting methods intended.
WARNING: Temporary support of panels during
assembly is the responsibility of the general contractor
or the onsite installation contractor. Temporary support should
only be attempted by trained individuals familiar with the safest
methods possible for securing loose or otherwise unsupported
panels. Stacking, leaning or blocking of panels when not
permanently supported may result in hazardous conditions.
Personnel injury or panel damage may result.
WARNING: Improper wiring or lack of proper ground can
result in re, electrical shock, injury or death. Disconnect
power to the Walk-In before performing any electrical repairs.
Field wiring or electrical repair should be done by a licensed
professional electrician. Follow all local building codes and laws
for electrical installation.
WARNING: In case of electrical re, disconnect the
power supply. Do not use water on electrical res. Smother
the re with an extinguisher rated for C-class res.
CAUTION: Per NEC 300-7, all raceways passing from
different temperatures shall be sealed with putty or other
method to stop the travel of moisture. Furthermore, all junction
box cover plates shall be sealed. Verify these seals are in place
and functioning properly after performing any service on the unit.
WARNING: Walking, climbing, or standing on non-
permanently supported panels may result in hazardous
conditions including falling. Personnel injury or panel damage may
result.

Important Things You Should Know
Shipping and Packaging
Upon receiving freight, check the bill of lading for
the correct number of pallets and check the product
for any shipping damage. Take photos of damaged
goods. Report issues to both the trucking company
and Imperial Brown, Inc. Contact the freight company
directly, at time of delivery, to le a claim.
Product Storage
If panels are to be stored for any length of time
before installation, make sure that they are protected
from moisture, sunlight, and temperature extremes.
Exposure to sunlight or excessive temperature will
make protective plastic sheeting difcult to remove
and labels may dry out and peel off. Moisture trapped
between panels can cause corrosion, such as white
rust.
Permits and Engineering
Imperial Brown is not responsible for obtaining any
permit, unless otherwise noted on the Sales Order.
Specic local building code, engineering, or regulatory
requirements are to be communicated to Imperial
Brown when placing the order.
Electrical Requirements
Electrical requirements for each electrical component
are identied on the Shop Print. Component
instructions and electrical wiring information for
specic components is supplied along with each
component. Component instructions may also be
found online by searching for the component brand
and model number.
Inside Safety Release
Check to make sure the inside safety release on
the door works correctly and that all personnel
understand how to use it.
Swing Doors—All swing doors equipped with a
positive latch or lockable non-positive latch include an
inside safety release mechanism. The safety release
allows an occupant to open a latched or locked door
from the inside. Push or turn the knob to release
the door. Follow the directions printed on the safety
release label. This includes padlock hasps and fullwidth removable locking bars.
Sliding Doors—All electrically-driven doors have a
Manual Release mechanism that allows the manual
operation of the door. This can be used by turning the
inside release handle to disconnect the door from the
drive. The door can then be slid open and close.
Sliding Door with Padlock Hasp—Sliding doors
equipped with padlock hasp locking devices have an
inside release knob. Turn the knob to unscrew the
lock hasp system from the wall, in order to let the door
open.

Important Things You Should Know
Ceiling or Roof Loads
Each unit is designed to meet certain intended loads.
Specic load rating for each unit is indicated on the
Shop Print.
Live Loads—Limit number of workers on ceiling.
Workers should be evenly spread out across the
ceiling. Maintain perimeter loading in lieu of center
(mid-span) loading whenever possible. Do not exceed
maximum loading (see Shop Print).
Environmental Loads – Outdoor Walk-Ins are
designed for specic environmental loads like snow
loads, wind loads, etc. Walk-In must be installed at its
intended location or environmental load requirements
might not be met.
Equipment Loads—The Imperial Brown Design
Department requires review of all equipment,
including refrigeration, re sprinkler, air handling,
and others, before it is installed or attached to ceiling
panels. Failure to submit a list of equipment for review
will void any warranty and may lead to structure
failure.
Installation Outside
Design Loads —These units are designed for wind
load, snow load, and snow drift. Erecting another
structure near the unit location may affect the load
requirements, as loads and drifts may change.
Drainage – Make sure that rain drains away from the
unit.
Installation Above Ground
Installing a unit above ground, such as on the second
story of a building, always requires an insulated oor.
See Floor Installation.
Service Hot Line
800.238.4093
Construction Details
Tie-downs, hold-downs and other requirements must
be installed or performed exactly as shown in the
Shop Print, with no substitutions for fastener size,
spacing or embedment. Variations require permission
of the Imperial Brown Design Department.
Penetrations
Be aware that electrical or mechanical penetrations
through the Walk-In may need to be addressed as
the Walk-In is being erected, prior to losing access to
these items.
Installation Over Fresh Concrete
Out-gassing from curing concrete may cause damage
to the metal nish. To avoid, ensure proper ventilation
(i.e. an open door).
Installation Next To Existing Walls
Two inches of clearance is recommended for air ow
and to allow for wall surface irregularity.

Shipping List
The Shipping List included in the Parts Box identies
every item shipped and indicates in what parcel (pallet
or box) it is located. It also indicates if a parcel is
located in another parcel (for example, the Parts Box
being in a pallet).
Panels are stacked in the best way possible to
minimize the risk of shipment damage. They are not
stacked in order of panel numbers. Use the Shipping
List to easily locate panels and hardware.
Cam Lock Fasteners
Panels are joined, using a 3/8” hex wrench (supplied)
on a cam lock device. Imperial Brown cam lock
fasteners must be fully understood before assembling
prefabricated panels. All cam locks must be in the
Open position before placing
panels together. Fasten the cam
locks as follows:

Assembling Panels Together
Panel widths are shown along each panel on the
plan views. See the Shop Print. Standard joint width is
1/16” between panels. This width may be different for
certain special joint types. Verify actual joint size on
the Shop Print. When fastening panels together, be
certain that dimensions are respected. For example,
irregular or loose tightening of the cam locks may
cause overall wall width to increase. See Figure 6.
