Installation of HPS III valve gate hot runner systems
1. Check the clearance
∆S
between the surface of the
upper pressure pad (pos. 1.4) and the surface of the
nozzle retainer frame plate (pos. 53) and compare it to
the value given in the drawing provided by EWIKON.
2. Place cooling ring (pos. 14.1) flush with socket head
screws (pos. 14.3, ISO 4762 - 12.9) on the manifold
(Pos. 1) and tighten it with the matching torque. See
chapter „9. Tightening torques“.
3. Insert the socket head screws (Pos. 14.2, ISO 4762 -
12.9) from the back through the bores in the drive unit
housing (Pos. 14), screw them onto the cooling ring
(Pos. 14.1) and tighten them with the matching torque.
See chapter „9. Tightening torques“.

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.
Pressurised systems
During installation all hydraulic or pneumatic supply lines must be de-
pressurised.
•
Injuries caused by flying parts or "whipping" hoses.
• Injuries to eyes caused by escaping pressurised liquids.
WARNING!
All clearances must be checked in cold condition!
In case of deviatons the clearances must be adjusted in an appro-
priate way (e.g. by machining the nozzle retainer frame plate or the
pressure pads of the manifold).
Attention:
The adjustment must not have influence on the dimension
X of the nozzle!
Checking of clearance when using nozzles for front installation
When nozzles for front installation are installed the contour pla-
te (pos. 56) must be installed before the clearance ΔS is checked.
Otherwise the measurement is falsified.
NOTE!
