4 Unpacking and lifting
Always follow guidelines and instructions as given in the air cooler product manual AHE00042.
Optigo CC air coolers are delivered on a wooden pallet, either covered with a wooden folding box or a wooden reinforced crate. Handling and positioning can take place manually (smaller models) or with use of a forklift. When more than one cooler units are delivered in a single shipment, packed air coolers may be stacked during transportation.
Respect the maximum number of stacked air cooler units.
max. units floor stacking 251-254 : 5 301-403 : 4 404-504 : 2
max. 2
In order to avoid damage to the air cooler or falling of the unit, ensure that the lifting forks fully cover the support pallet.

Manually turn the air cooler into mounting position on a second wooden pallet. Use adequate protective material to prevent the driptray from damaging. The cooler is now ready to be lifted into mounting position.
CC400/500 & CCB400/550
Unpacked models 400/500 are in mounting postion. Remove driptray (supplied unmounted).
For CC400/500, turn mounting brackets into correct position and secure with supplied fixing materials.
The cooler is now ready to be lifted into mounting position.
