2. DELIVERY AND HANDLING
2.1
Delivery method
All models of this series are delivered with the maximum possible elements mounted in our factory. Depending on the height of parts,
the unit will be divided in order to lower the transport costs. Generally the deliveries are carried out in two or more parts. To facilitate
the handling operation, the single parts are laid on a wooden pallet.
Connection elements to be used on site (gaskets, silicone, nuts and bolts) are supplied in a separate box.
2.1.1
Lower body
This is composed of the following elements:
•
Cold water basin with all its elements
•
Secondary circuit centrifugal pump (delivered loose in case motor power is over 5.5 kW)
•
Secondary circuit external pipe (lower part – delivered loose)
•
Air intake section
•
Coil primary circuit (if not delivered separated)
2.1.2
Middle body (if any)
This is composed of the following elements:
•
Coil primary circuit (if not delivered together with the lower body)

•
Air system (Fan(s), Motor(s))

WOOD SUPPORTS AS WELL AS THE PLASTIC OR CARBOARD SHEETS HAVE TO BE REMOVED BEFORE INSTALLING THE COOLING
TOWER IN ITS FINAL LOCATION. PARTICULAR ATTENTION HAVE TO BE GIVEN TO CHECK WATER BASIN, WATER PIPES AND WATER
DISTRIBUTION SYSTEM TO BE FREE OF ANY PARTS WHICH CAN CAUSE PROBLEMS OR DAMAGES TO THE NORMAL FUNCTION OF THE
COOLING TOWER.
ALL AUXILIARY MATERIAL NEEDED FOR ASSEMBLY ARE DELIVERED IN A BOX, INSIDE THE LOWER BODY.
2.2
Handling
To facilitate the handling of each single part, eyebolts are fitted, located at the top, so that lifting and handling, by crane, can be
carried out easily. This can be observed in figures 1 & 2.
THE EYEBOLTS ARE ONLY FOR USE IN TRANSPORTING AND HANDLING THE BODY THAT THEY ARE ATTACHED TO. ALL EYEBOLTS
MUST BE USED IN THESE OPERATIONS.
THEY MUST NEVER BE USED FOR MOVING THE TOWER ONCE IT HAS BEEN ERECTED AND
BOTH BODIES ARE ASSEMBLED.
The lower body handling will be carried out using all its eyebolts due to its weight, as indicated in fig. 1.
To move the upper body, all eyebolts will be used as well, as indicated in fig. 2
