■ Field Assembly
If you choose to assemble your Aquatower at the job site,
your Aquatower will be shipped unassembled with complete
assembly instructions.
The following table shows the sizes and weights of the
largest Aquatower components for each model. You can
use this information to plan your rigging and transportation
needs.
Unassembled tower shipment may add 3 to 5 weeks to
normal lead times. Your Marley sales representative will be
glad to help you plan for your unique needs.
Volumes shown are maximums for the flowrate ranges indicated.
Actual volumes will usually be less. Contact your local Marley sales
representative for more specific information.
Note: For economical transportation, Aquatowers are normally
packaged unassembled when shipped from the UK by sea or air
freight.
