Part Number GENERAL
Thank you for choosing Hussmanns Innovator
Cooler Door System. This document provides
information necessary for successful installation
and operation of the door system.
The door nameplate is attached to the top of the
door, handle side, behind the magnetic gasket.
The frame nameplate is located on the top left
near the switch.
ALWAYS*CLEAR GLASS
Hussmann recommends using a soft cloth with
isopropyl (rubbing) alcohol to clean the inside
(coated) glass surface. Isopropyl alcohol does not
freeze and evaporates without leaving residue.
Always allow the surface to dry before closing
the door. Use of abrasives may damage the
coated surface and void the warranty. Labels
(stickers) applied to the coated surface will cause
damage and oid the warranty.
APPLICATION
The Innovator Cooler Door System is designed
for installation in new medium temperature or
low temperature walk-in coolers with insulated
structural walls. To maintain structural integrity
of the cooler wall and the door system. the cooler
wall must be manufactured with a reinforced
opening to match the door frame.
Frames may be joined when more than a 5 door
length is needed. Frames to be joined are manu-
factured without the vertical outside frame
flange.

Innovator Cooler Door System
Standard Reinforced Opening
Door systems manufactured with
Innovator or Innovator II doors have
an anti-arc ballast. When re-starting
lamps, turn power off then on. ELECTRICAL SPECIFICATIONS
Appropriate electrical power must be available
for the door system, including lighting and
heaters. Check the nameplate for minimum
circuit ampacity and maximum overcurrent
protection device. Always follow NEC guidelines
and local codes.
SPECIFICATIONS FOR OPENING
Each door frame is 1 to 5 doors wide. Several
standard frame heights are available. Always
compare the wall opening dimensions with the
frames to be installed.
SHIPPING DAMAGE
All equipment should be thoroughly examined for
shipping damage before and during unloading.
This equipment has been carefully inspected at
our factory. Any claim for loss or damage must be
made to the carrier. The carrier will provide any
necessary inspection reports and/or claim forms.
PREPARATION
Clear an area outside the wall opening to lay the
frame flat and work around it. Gather tools need-
ed for installation.
Doors are shipped separately from the frame. Set
doors aside until frame is installed. Lay the frame
face down. Remove all packing materials, pack-
aged parts and tape. Take care not to scratch or
otherwise damage frame face.

Typical Tools Needed to Install
Innovator Cooler Door System INSTALL FRAME
Apply Sealant
Apply field-supplied silicone sealant between
edge of gasket and outside edge of frame.
Check Frame and Opening for Square
Verify the frame is not racked (out of square) by
measuring from one corner diagonally to the
other. The measurements must be the same.
Verify that the opening is large enough for the
frame. Use a long level (4 ft
(1220 mm)
or more)
to determine if the opening is level side to side. If
shims are needed, they must be used under the
frame at the bottom of the opening, or at the
sides.
Place Frame in Opening
Lift frame by mullions to avoid gaskets and
sealant. Position bottom of frame in opening and
then tilt top of frame toward opening. Take care
that wiring from wireway at top of frame is not
damaged.

Add Shims
When Needed Use the level to ensure the frame is plumb within
the opening. Use shims as needed below and to
the side to keep the frame level.
Once the frame is properly positioned, large
clamps should be used to hold frame in position.
Fasten Frame to Cooler Wall
Use screws provided to fasten the bottom frame
to the wall.
Verify frame is still square.
Fasten side frame to wall with screws provided.
Use shims as necessary. Do not distort frame by

Frame sides to be joined will have no front face
flange
Install the first frame as above, and prepare the
second frame. Apply 1 in. wide gasket between
wipes of each frame side to be joined. Lift the
second frame into position and fasten the bottom
as above.
Verify the second frame is still square.

Do not distort frame sides or top.
Once all frames are installed, verify overall frame
is square and plumb.
SEAL INSIDE FRAME PERIMETER
Apply a small continuous bead of silicone sealant
around the inside of the frame to seal the frame
to the wall.
ATTACH DOOR HANDLES
Carefully lift the magnetic gasket away from the
frame nearest the handle location to expose the
mounting screw holes as shown in below.
Install handle and screws carefully (if gasket is
damaged, it must be replaced). After installing
screws, gasket should again lie flat
