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 cooler units are delivered in a single shipment, packed air coolers
may be stacked during transportation.
In order to avoid damage to the air cooler or fall-
ing of the unit, ensure that the lifting forks fully
cover the support pallet.
