1.3 Instructions for storage, transport, loading and unloading of
the unit
CAUTION
Outdoor units must be moved and stored vertically to prevent oil from leaking from the compressor.
Delivery inspection
The unit should be carefully inspected for visible damage or abnormalities as soon as it is received.
Any abnormalities or damage to the unit should be communicated to both the transportation and
insurance company in writing.
Storage instructions
The unit should be stored in a place suitable to the purpose (warehouse or similar), protected from the
weather, water, humidity and dust.
Cover the unit with a canvas of a suitable size.
The unit should be appropriately protected from knocks and dust, ensuring the protective parts it was
supplied with remain in place. Where these are not in place, establish the necessary protections and/or
barriers to keep vehicles or fork-lift trucks away.
Transport, loading and unloading of the unit
The units should only be handled by personnel from the company responsible for their installation.
Transport of the unit should be in such a manner that no damage is caused by faulty or inadequate
mooring to the bed or body of the vehicle.
Where necessary, protect all of the edges of the unit against knocks and scratches and moor it to the
bed or body of the vehicle using suitable textile belts or slings to keep it perfectly still.
Loading and unloading the unit from a truck or trailer should be on flat, solid ground using an appropriate
crane with sufficient capacity.
1.3.1 Hoisting points
The points designed for hoisting the unit are located on the beams on its base.
Before hoisting the unit, check that the cables or slings are firmly hooked to these points and make sure
the crane and the cables or slings are capable of lifting the weight.
Place spacers at the top of the unit to prevent the cables or slings from touching it.
Attach guide ropes so that the unit does not rotate freely.
The cables or slings should be long enough to form an angle of over 45º to the horizontal plane. Hoist
the unit keeping it in a horizontal position.
DANGER
There should not be onlookers within a radius of 10 m of the unit when it is being hoisted.
