Installation of HPS III valve gate hot runner systems
1. Install the drive unit with pre-installed valve pin (pos. 11).
Insert the valve pin carefully into the valve pin seal in the
manifold. Apply axial load only. Tilting or bending caused
by lateral load must be avoided. Slowly push the valve
pin through the manifold and the valve pin guide in the
tip insert of the nozzle until the drive unit sits flush in the
cutout of the clamping plate (pos. 51).
2. Insert the socket head screws (pos. 11.3, ISO 4762 -
12.9) from the back through the bores in the drive unit
and screw them into the clamping plate (pos. 51).
Tighten with matching torque.
See chapter „9. Tightening torques“.
3. Wire the electric drive units according to the wiring sche-
me provided by EWIKON.
4. Wire the nozzles and the manifold according to the
wiring scheme. Please pay attention to the notes in
chapter „5.6 Electrical connection of hot runner sys-
tems“.
5. In order to clearly identify the hot runner system attach
the type plate included in the delivery prominently to the
operator side of the mould.

installation in the clamping plate
When the hot runner system is not filled the valve pin can be installed
in cold condition.
If the hot runner system is filled it must be heated to operating tem
-
perature before the valve pin is installed.
NOTE!
Connected power supply during installation
Risk of deadly electric shock or severe injuries due to live compo-
nents.
• The hot runner system and the mould have to be disconnected
from the voltage source during installation.
HAZARD!
Sharp edges and heavy components
• Cut injuries to body and extremities, mainly to the hands.
•
Crushing of fingers or hand.
Control of live components before installation
The electrical equipment of the hot runner system should be
checked, especially those areas which will no longer be accessible
after installation. Physical injuries such as an electric shock can be
prevented that way.
Please check
• if cables are kinked or squeezed.
• if cable insulations are undamaged.
