Unpacking the AHU-CL1 and VacClean
CAUTION
Observe correct anual handling procedures when re oving the syste fro the packaging. The
syste will exceed the reco ended anual handling li it. The AHU-CL1 weighs 30KG
Depending on the quantity of units delivered at once there are different possible packaging methods.
The ystems will either arrive on a pallet base with a cardboard surround or in a wooden packing crate.
The removal of the system from both types of packaging is listed on the following pages.
Pallet Based Cardboard Container
This shipping method will be used for lower volume shipments. To open the box without causing
damage to the unit the following removal method should be used:
1. Inspect the package for any damage, if there is any please photograph before removing any of
the packaging
2. Remove the delivery note and any other required paper work from the sides and lid of the box.
3. Remove the banding and remove the lid from the box.

Page 16 of 102
4. Inside the container there will be several boxes which contain different parts of the system.
These will need to be removed to be unpacked. With care taken for the largest box which
contains the AHU-CL1 and will need to be removed by 2 people due to its weight. The easiest
way to gain access is to remove the box sides (one piece)
5. All of the boxes can then be un-packed and the goods removed. (see the section of ‘what is
Included’ to make sure all of the parts are included in the container)

Wooden Packing Crate
CAUTION
The etal clips are under tension. These are re oved by levering fro the tabs located on each end
of the clip. It is i portant to steady the other side of the clip to ensure it does not spring off.
This shipping method is used when larger quantities are consolidated into one container. To open the
crate without causing damage to the products or operator please follow the instructions below:
1. Inspect the crate for any damage, if there is any please photograph before removing any of the
sides or packaging inside.
2. Remove the delivery note and any other required paper work from the sides of the crate.
3. Remove the Lid with a removal tool or a pair of flat headed screw drivers

4. The side that needs to be opened first will be marked. It is usually the side marked with “open
this side first”, or has all of the paper work attached to it.
5. To remove the side, unclip the metal clips from around the outside of this panel only, make sure
you observe the caution at the start of this guide.
6. Once the side has been removed the boxes containing the system can be removed and
unpacked, checking for damage as they are removed.
7. To continue to flat pack the crate remove any shelves inside the crate, which will be screwed in
place. Then continue to remove the rest of the clips.

System Overview

AHU-CL1 Manual
Page 20 of 102
AHU-CL1
The main components of the AHU-CL1 are:
1.Touchscreen Control Interface
2. On/Off Isolator witch
3. 3 Phase Power Inlet
4. 16A Circuit Breakers
5. Cooling inlets
6.Vacuum Duct Connection
7. Positive and Cooling Air Connections
8. Filter Compartment
9. ignal interface
Function
The Vacuum pressure required to clean the web is produced by the AHU-CL1. The AHU-CL1 contains two
pumps that provide the pressure required for the cleaning. These pumps are controlled by the touch
screen which also monitors the condition of the integrated 5-micron filter bag.
The black carry handles need to be moved during install and mounting, which is shown above with the
red arrows.
