Operating Environment

All Hussmann Cases have been factory tested to AS1731, 25C at 60% RH. For best performance, store temperature

should be maintained at or below 24C at 50% RH, otherwise an “air ventilation kit” may be required to avoid under or rear

cabinet sweating.

To avoid condensation build-up, cases should be positioned to allow air to freely circulate around the underside and rear

of the case. Ideally, the floor will be levelled.

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.

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 27 (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.

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 27).

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.
