5. Description
Construction of Machine
The machine stands on four feet, adjustable for height
and is arranged for integration into a vacuum packing
line.
Principle of Operation
The VC999 85.47i Shrink Tank operates on the method
of shrinkage by brief immersion in hot water. Incoming
product is registered by the photo cell (21) and starts
the fully automatic immersion cycle. The product is
brought into the machine and immersed in the hot
water. This causes the shrinkable bag (especially
projecting portions) to fit closely to the product.
When the immersion cycle is complete the product is
automatically removed from the Shrink Tank.

8.1 Electrical Connection
WARNING
Electrical hazard! Danger of death –electric shock!
The machine may only be connected to the power
supply by a qualified expert (electrician) and in
compliance with local regulations!
The machine is supplied without connecting cable.
This 4-core connecting cable (3 phases + E) should
be measured by the electrician and connected to the
main switch.
The cable is brought into the machine from above
through the conduit gland (Fig. 1, Pos. 1) or from
below through the opening in the machine. In this
case the conduit gland (Fig. 1, Pos. 1) must be
exchanged for the closure plug in the main switch
box.
As well an earth potential differential cable has to be
installed. The wire must have the same section as the
main cable wire. A special terminal (54) is prepared
left of the air service unit.
• Check whether the local supply voltage, frequency
and fuse protection conform with the data on the
type label (19) or the technical data in chapter 4. If
not the machine should not be connected.
NOTICE
If the direction in which the platform moves does not
correspond to the installation of the equipment the
machine should be switched off and 2 or 3 phases of
the motor driving the platform have to be
interchanged.
NOTICE
The first switch-on of the machine must only be
done by the VC999 Customer Service.
8.2 Compressed Air Connection
• Remove back panel (22).
• Push the compressed air hose (ID 9 mm) on to the
nipple of the compressed (31) air maintenance unit
and secure with a hose clip.

• Replace back panel (22).
NOTICE
To keep to a minimum the amount of condensate
entering the service unit or the point of use an air
dryer must be installed in the air supply line.
Otherwise a water-trap at least is necessary. The
condensate which collects in the sight-glass (33) of
the service unit is vented automatically through the
valve (34) at every switch-on.

8.3 Water Connection
The VC999 85.47i Shrink Tank can be fed with cold or
warm water.
NOTICE
With hard water it is desirable to install a water softener
in the water supply line. This reduces lime deposits and
minimises cleaning.
For the water-pressure a manometer and a regulating
tap should be provided on site.
To clean the filter (38) the Shrink Tank must be
disconnected from the water supply by means of a
stopcock.
Clean the filter 1 day after first start-up according to
Section 13.1.2.
Water connection from above: Connect by flexible
hose to item 35, threaded joint R½“.

the supply line and that the water unit is not twisted
when tightening.
8.4 Steam Connection
Only for versions with steam heating:
NOTICE
A manometer (setting 6 bar max) and a safety value
set for 8 bar must be provided on site. To clean the
filter (40) it must be possible to isolate the shrink tank
from the steam supply with a steam valve.
WARNING
Risk of scalding from the discharge of hot steam!
