II. Unpacking Your Cabinet
This chapter aims to provide relevant information on how to handle the cabinet properly upon receipt. Failure
to follow these instructions may damage the cabinet. We strongly advise you to read this chapter carefully
before proceeding further.
2.1 Step-By-Step Procedure
1. Inspecting the Crate, Pallet, Boxes.
»Upon receipt of your new cabinet, inspect all cartons. If there is any visible damage to the exterior please
refer to Damaged Freight Claim Information on our website.
2. Moving the Pallet.
»The pallet is designed to protect our cabinet from any foreseeable circumstances. However, excessive
impact onto the boxes or pallet may also damage the cabinet. Prevent any direct impact or hitting to the
pallet when moving.
»Whenliftingthepallet,alwaysensurethattheoorjackormechanicallifttruckhasfullyenteredunder
the pallet in order to achieve stability. Failure to do so will increase the risk of the pallet falling off the
oorjackormechanicallifttruckduringhandling.Pleaseuseasuitableextensionbarwhennecessary.
3. Opening the Boxes.
»If you did not receive one or more of the parts listed on the packing checklist, or if any of the items are
damaged, please refer to the Damaged Freight Claim Information on our website.

Information on our website.
»We recommend leaving the cabinet secured with straps to the pallet until the cabinet is located in its
approximatenalpositiontofacilitateeaseandsafetyinhandling.
Note: Choosing the best location for your cabinet in order to achieve optimum operating performance
is determined by a number of factors. Please refer to the next chapter for some guidelines.
5. Moving the Cabinet.
»Whenliftingthepalletwiththecabinet,alwaysensurethattheoorjackormechanicallifttruckhasfully
entered under the pallet. This is to increase the stability of the cabinet and reduce the risk of the cabinet
falling down. Please use a suitable extension bar when necessary. During the moving of the cabinet,
ensure there is enough distance between the supports of the pallet and the ground. Dragging the pallet
against the ground will damage the pallet and possibly your new cabinet.
»When removing cabinet from pallet or placing cabinet onto pallet, use at least two people.
6. Removing the Strapping.
»Remove the strapping by cutting it at a safe position to prevent any scratching the surface of your new
cabinet.
»Do not discard the packaging material for your cabinet until you have checked all of the components,
installed and tested the unit.
7. Lifting the Cabinet.
»The cabinet can be lifted in two sections: The HEAD unit and ENCLOSURE.
»Install the cabinet on the existing work surface or Air Science support stand (if ordered).
Note:
»When installing the cabinet onto an existing work surface, ensure that the structure can safely support
thecombinedweightofthecabinetandanyrelatedequipment.Somemodicationstotheworksurface
may be necessary.
»The work surface should be smooth, non-porous and resistant to the disinfectants and chemicals used
in conjunction with the cabinet.
