Unpacking 2.1
•
Remove the transport packaging and check that the product has not been damaged
in transit and that the consignment agrees with the specifications.
•
When lifting the unit take care not to apply stress to pipes and heat exchanger as this
may weaken them. Avoid lifting the unit by holding the heat exchanger.
Note : Risk of injury lifting heavy objects.
Preparation 2.2
•
AL Mini City must be placed on a wall, in upright position. Use screws or bolts
suitable for the material of the wall and for the weight of the unit.
•
Choose a suitable installation area in accordance with official regulations.
The substation may generate sounds during operation caused by pumps, regulators
systems, flows etc. This should be taken in consideration during installation of the unit
so that possible operational sounds affect the surroundings as little as possible.
•
Alfa Laval recommends that the substation is mounted on well-insulated walls, such
as outer walls or on concrete walls.
•
Check the applicable regulations of the primary heating supplier.
The available differential pressure should be at least 50 kPa and at most 600 kPa.
•
Where the differential pressure is higher, a differential pressure controller should be
added to the installation.
Mounting the first fix-jig 2.3
•
Mount the first-fix-jig on the wall with two screws.
Make sure that there is enough space above for the substation and below for the
expansion vessel.
Alfa Laval recommends having 900mm from floor to upper edge of the first fix-jig.
