Operating Environment
All Hussmann Cases have been factory tested to AS1731, 25C at 60% RH. Hot food display cabinet is also tested to
AS4322.
Cases must not be positioned in areas that may be subject to cold or air currents such as ventilation ducts, open doors or
windows, direct sunlight, electric fans or ovens, etc. Otherwise the cabinet may show poor temperature performance or the
operating life is affected.
NOTE
Refer to product MSDS for all hazardous substances used
during installation in relation to their application, PPE, first aid,
disposal and emergency management. Refer page 20 (Risk
Analysis)
For MSDS sheet contact your Hussmann Representative
Handling and Transporting cases
Case dimensions can be found in the product engineering data sheets.
(This manual is a guide only. Always refer to the latest case information available from Hussmann Customer Service)
Always ensure that the moving device is of a suitable type, and has sufficient lifting capacity for the case weight and
dimension. Always lift cases from the underside.
Refer to and follow the manual handling policies of your Company when moving cases.
CAUTION
Care must be taken to avoid damage to drainage
outlets and electrical equipment mounted under or
at the rear of cases.
Shipping Damage and Shortages
If possible, it is recommended that packaging be removed from the cases before they are moved into the store.
After removing packaging, inspect the case for any shipping damage and ensure that all case inclusions, such as trims etc
are accounted for. Immediately report any shipping damage to the carrier and inform Hussmann Customer Service of any
short supplies.

Installation
NOTE
Information in this manual is to be followed in conjunction
with specifications, work practices and regulations of the
customer, installing company and relevant industry.
Positioning and Levelling
Each case has a unique identification number as follows:
##### - ## - ##
Job no. Line-up no. Case sequence no.
(within line-up)
Example: 106076.42.4 identifies this case in the 4th sequence of the line 42 for the job 106076.
As well as on the packaging, the case identification number appears as a serial number on the rating plate (most commonly
located on the ceiling panel left hand end of the case) refer to Fig (3) and is printed on a decal on the rear of the case ref
Fig (4). The case sequence number is also written on a ticket on the front panel.
Fig (3) Rating Plate
Fig (4) Decal rear of case with case sequence number

PRODUCT INSTALLATION MANUAL DH13 HOT FOOD
_________________________________________________________________________________________________________________________
Page 6 Hussmann
Cases must be positioned so that line-up numbers and case sequence numbers run in succession left to right standing in
front of the cabinet.
CAUTION
Ensure the lifting capacity of the trolley, etc. is
sufficient for the case. Refer to the product
engineering data tables and Risk Analysis (page 20).
To position the cases:
1. If the plinth surface is level, position the case designated as line up number 1 and case sequence number 1 in the
required position.
2. If the plinth surface is not level, determine where the highest point of the plinth is, and position the case allocated
to this position first.
3. Adjust the case height using the adjustable feet (if fitted) or metal shims (do NOT use timber) to ensure the case
is level to within +/- 1.5mm from front to back and side to side and chassis of case is NOT twisted. Maximum
25mm adjustment.
Fig (5) Levelling feet adjustment
NOTE
It is important that all cases are level for correct case joining and operation. If
cases are not properly levelled and positioned, door misalignment will be evident,
resulting in the job needing to be redone at complete cost to the installer.
Hussmann is not liable or responsible for the cost involved in fixing
problems arising directly from the installers’ failure to follow the
requirements outlined in this manual.
DO NOT SET CASE LEVELS OFF THE PATCH END fitted to a case.

Operation
Loading Merchandise
Cases should only be stocked with merchandise for which they were manufactured as indicated by the case model number
on the rating plate (see Fig (15): Rating Plate) that is typically located, on the rear back panel at the lower right hand end
as viewed by the operator.
Fig (15): Rating Plate
Use only fittings and accessories supplied with the case or approved by Hussmann.
CAUTION
Do not climb in or on the case as this may result
in personal injury and/or case damage.
Cleaning and Maintenance
Daily Checks
•If an alarm system is not part of the refrigeration installation, the temperature of each case should be checked on
a daily basis via the thermometer that may be located inside the product area or via another reliable method.
The case temperature should be in the range of 60C - 65C when stabilised.
Up to three separate readings may have to be taken to ensure all the case temperature aren’t being taken during
thermostat cycling.
If it is consistently outside this range, contact Hussmann or your service contractor.
•Visually check the case for damage or spills and take appropriate remedial action.
CAUTION
If any damaged electrical components are
identified during inspection isolate case
power and contact service contractor.
•Visually inspect drain strainer and drain for any debris which could result in the drains becoming blocked with the
possibility of spilling on the floor creating a slip hazard

cleaning.
Important Notes
•Do not use hot water on cold glass surfaces as the glass may shatter and cause serious injury.
•Do not use abrasive, solvent, ammonia or oil-based cleaners.
•Do not use steam or a high-pressure system to clean the case.

Appendix 3 Setting Table –Part of PED.
Appendix 4 Attaching case ends
Appendix 5 Top glass horizontal adjustment
Appendix 6 Front glass door camber adjustment
Case ends are normally fitted in the factory; however, they occasionally need to be attached to a case on-site. Use this
procedure when an end attaches to a single case and when it is common to two cases.
Ensure that correct and appropriate manual handling techniques are applied when fitting a patch end.
Cases must be sealed before attaching case ends.
To attach a case end
1. Carefully run a knife around the inside rim of the end trim, taking care not to scratch the case end surface, and
remove the case end membrane.
2. To assist in screwing in the Lag screws, drill a 6mm hole in the mounting positions shown, using the 10mm diameter
fixing hole location. Ensure you do not drill completely through the End. see Fig (16)

3. If the end is common to 2 cases, repeat step 2 for the other side of the case end.
4. Insert 2 hex nuts onto one of the lag screws, lock nuts together and drive screw through the hole at the top of the
case end until the lag is fully embedded in the end.
5. Remove the nuts from the lag screw and repeat step 4 for the remaining holes.
6. Pull up the case ends lightly against the case.
7. Adjust the case so that the end fits comfortably around the canopy and the top of the case and is level, from front
to back with the case roof.
8. Secure the case end with the lag screws and bolts
9. Apply either black or white silicon (depending on the interior colour of the case) all the way along the inside joins
between the case end and end frame. see Fig (17)
Fig (17) Silicon ends to case
10. Applying slight pressure, run your finger along the length of the silicon.
11. Remove all remaining packaging material from the case end and case and trim
12. Attach the end kickplate and, if required, silicon seal to the floor.
