Electrical Connection –access from rear of case. Plug and lead is coiled up underneath the case, next to bottom
electrical box.
figure 3 rear view of case with electrical plug
Operating Environment
Cases have been factory tested to AS1731, 25C at 60% RH. For a better performance and having operating
safety margin, store condition is recommended to be operating at or below 24C at 50% RH. Otherwise an “air
ventilation kit” may be required to avoid under or rear cabinet sweating
Air circulation gaps between the wall and the back of the case are shown in Figure 1 & 2, but reference should be made
to the PED for the latest, up to date information.
Cases must not be positioned in areas that may be subject to heat 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. If fitted within a gondola run refer to appendix 2
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.

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 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
CAUTION
Ensure the lifting capacity of the trolley, etc if used is
sufficient for the case. Refer to the product engineering
data tables at the front of this manual for case weights
and Risk Analysis (page 14).
To position the cases:
Once case is in position adjust the feet so the case is fully supported by the feet and level (Ensure the case is level
to within +/- 1.5mm from front to back and side to side and chassis of case is NOT twisted).

Monthly
A thorough condenser clean and maintenance check should be carried out on a monthly basis by qualified and approved
refrigeration and electrical engineers. The following procedures should be undertaken as a minimum.
Cleaning
1. Clean the condenser unit with a soft brush or a vacuum cleaner. The dust and fluff obstructs the good air
circulation. To reach the condenser unit, remove the protection grill, clean it very carefully (avoid touching other
components) and put the grill back in its place.
Six monthly
A thorough cleaning and maintenance check should be carried out on a six monthly basis by qualified and approved
refrigeration and electrical engineers. The following procedures should be undertaken as a minimum.
Inspection
1. Check that all case panels and trims are secure and undamaged
2. Check for rust and paint damage
3. Ensure all cable connections, including screw terminals, earth leads and straps are secure
4. Ensure insulation to all electrical components including solenoid valves, fans, heaters, controls, earth terminals
and lights are sound
5. Carry out electrical safety tests, including earth continuity and insulation resistance
6. Check the defrost water dissipater tray heater is de-activated. When empty the water level is below the sensor tip.
7. Ensure that there are no refrigerant leaks.
8. Check that all fans, valves, lights and controls are working
Clean
CAUTION
