Leveling
IMPORTANT! IT IS IMPERATIVE THAT CASES BE
LEVELED FROM FRONT TO BACK AND SIDE TO
SIDE. A LEVEL CASE IS NECESSARY TO INSURE
PROPER OPERATION, WATER DRAINAGE,
GLASS ALIGNMENT, AND OPERATION OF THE
HINGES SUPPORTING THE GLASS. LEVELING
THE CASE CORRECTLY WILL SOLVE ALL HINGE
OPERATION AND GLASS ALIGNMENT
PROBLEMS.
NOTE
A. TO AVOID REMOVING CONCRETE FLOORING,
BEGIN LINEUP LEVELING FROM THE HIGHEST
POINT OF THE STORE FLOOR.
B. WHEN WEDGES ARE INVOLVED IN A LINEUP,
SET THEM FIRST.
IF A WEDGE IS USED IN THE MIDDLE OF A LINEUP,
THE WEDGE MUST BE SET ON THE
HIGHEST POINT ON THE FLOOR FIRST, WITH THE
REST IF THE LINEUP BEING LEVELED FROM
IT. THE Q3-DC CASE HAS ADJUSTABLE LEGS TO
ALLOW FOR LEVELING.
Q-3 Glass Adjustment
Proper adjustment of the side-to-side position on the
glass clamp on Vieler Streamline hardware such as used
on Hussmann Q series service cases is critical to proper
operation of the glass hardware. Failure to properly adjust
the glass clamp can result in failure of the hardware and
possible injury to personnel.
When setting or repairing cases, the glass clamp is
frequently adjusted from side to side once the cases are
set in order to control glass gaps or compensate for poorly
installed case line ups. Due to the unique design of this
type of hardware, using practices common to other types
of hardware can result in the above failures.
Step 1: Level Case
The canopy hardware and glass gaps are set at the factory
for proper !t with the Cases Square and level. Before
attempting to do any adjustment of the canopy hardware,
ensure that the cases are set square and level. Additionally,
the adjoining cases must be pulled together tightly.
To adjust the front glass please follow these steps
Before you start any adjustments make sure the cases are
level, Front to Back and side to side
Figure 5
Figure 6
Step # 2
To level the cases remove the front and rear close-offs, You
can adjust the Height by turning the base leg adjusters
Figure 7
When you turn the leg adjuster clock-wise the case will
go up.
When you turn the leg adjuster counter clock-wise the
case will go down.
Installation (Cont'd)

IMPORTANT: Attempting to compensate for poor
installation practices by manipulating the canopy
hardware will result in unsatisfactory workmanship
and possibly cause hardware failure and/or injury.
Step 3: Adjusting Glass Height
After the cases are set and level, rear covers must be
removed to access the glass height adjusters
Figure 8
Some cases have wrapping boards installed, the wrapping
boards need to be removed to be able to remove the small
rear covers. Unhook at K-99 bracket.
Remove the small rear covers under each rear canopy arm
to access the arm adjusters.
Step 4:
Make sure
these bolts at
the bo!om
are "ght
Figure 9
Loosen the two lock screws on the side (do not remove)
Figure 10
To properly adjust the height of the glass requires that both
hinge arms of each section of glass be loosened before
attempting to change the glass position.
Turning the bolt clock-wise, the front glass will go down.
Turning the bolt counter clock-wise, the front glass will
go up.
Figure 11
After all the glass height has been adjusted, go back and
tighten all the lock screws.
Installation (Cont'd)

15
Glass Height should be centered
on “V” glass seal
Figure 12
Glass must be parallel to ledge when viewed from front.
IMPORTANT: Attempting to compensate for poor installation practices by manipulating the canopy hardware
will result in unsatisfactory workmanship and possibly cause hardware failure and/or injury.
Step 5: Glass Side to Side Adjustment
The glass gaps can be slightly optimized by moving the glass and glass clamp assembly side to side. This should be
done as the !nal adjustment only after the glass/canopy height of the cases are set and leveled to each other. The canopy
hardware on adjoining Q Series cases should be screwed together with the ¼”-20 THD screws included with the cases.
There are threaded holes provided in the stationary portion of the top hardware for this purpose.

To properly adjust the glass gaps requires that both hinge arms of each section of glass be loosened before attempting
to change the glass position.
To shift the glass side to side or front to back at the glass clamp open the glass and loosen the TORX T-15 screw.
To shift the glass side to side
or front to back at the glass

Torque Specs:
3Nm= 2.21 Foot-pounds
8Nm= 5.9 Foot-pounds
IMPORTANT: Attempting to change the glass position by loosening only one side or by forcing the clamp
sideways will result in damaging the hardware and its eventual failure. Loosening the hinge arms requires
loosening the attachment screws and setscrews on both hinge arms on the section of glass.
IMPORTANT: It is critical to use the proper size Torx or Hex wrench for the fasteners to avoid stripping the
fasteners.
Installation (Cont'd)

18
Loosen the fasteners only as needed to allow the glass clamp to slip to the desired position.
Reposition the glass and glass clamp assembly as needed and verify its position by carefully closing the glass to check
clearances.
Once the glass is in the desired position, retighten the fasteners at the hinge arms with the proper wrench.
Recheck the glass position and double check that the fasteners are properly torqued.
IMPORTANT: It is critical that the hinge arm washers or bushings that fasten the hinge arms to the stationary
portion of the upper glass hardware do not have any side pressure on them. Even the slightest side pressure
will result in the failure of the hardware. If the retaining clips or hinge arm washers or bushings at each hinge
arm have any side pressure it is necessary to repeat the adjustment procedure.
When properly adjusted, the hinge arm washers or bushings will have a slight side-to-side free play.

Q-3 Shelf Adjustment
Proper leveling and adjustment of the Shelves is critical to
the aesthetics of the case. Failure to properly adjust the
shelves can result in failure of the hardware and possible
injury to personnel. When setting or repairing cases, the
shelves are adjusted vertically. Due to the unique design
of this type of hardware using practices common to other
types of hardware can result in the above failures.
Step 1: Level Case
Ensure case is leveled if not done so already.
IMPORTANT: Attempting to compensate for poor
installation practices by manipulating the shelf
hardware will result in unsatisfactory workmanship
and possibly cause hardware failure and/or injury.
Tools needed for shelf adjustment:
T-25 STAR Allen Wrench
Step 2: Adjust Shelf Height
After case has been set and level, loosen torx screws in
demonstrated location below.
Loosen
Torx Screws
After Torx screws have been loosened slide shelf brace
vertically along the Key Rail to the designated height of
preference and tighten torx screws to hold in place.
Repeat exact steps to opposing case side.
Step 3: Level Shelf
Once all height adjustments have been made ensure to
level the adjusted shelves from one side of the case to
the other.
For Shelf Removal
Loosen Torx screws as shown on step 2 to both ends
of the feet to the keyrails and slide up. There is enough
clearance between the top key rail and the canopy of the
case to remove without any disassembly of the case.
