Overview
System Description
The heated platen kit is a field installed kit to add heat to
the platen. The additional heat may change the viscosity
properties of the material and allow the material to flow
easier through the system.
The heat is controlled by Graco Control Architecture
components: High Power Temperature Control Modules
(HPTCM) and the display module. The display module
provides the user interface for the entire VPM system.
Power Requirements
A 20A (minimum) - 30A (maximum) circuit breaker must
be installed on the incoming power supply.
* Add to power requirements of VPM system. Amps
maximum per leg shown.

Adjust Rotary Switch
The rotary switch setting indicates which zone the tem-
perature control module will control in the system. The
high power module uses an 8-position rotary switch.
Set the rotary switch (S) to the specific selection accord-
ing to the settings listed in the following table.

Installation
Power Requirements
Ensure that the electrical panel located within the Power Distribution Box has the correct circuit breakers for installing
the kit. If the current Power Distribution Box does not have this configuration, contact your local distributor inquiring
about a Power Distribution Box upgrade kit.
Grounding
Ground the system as instructed within this manual.
Setup
1. Access the Platen
a. Perform Remove Drum Procedure found in
VPM Instructions manuals.
b. Perform Shutdown Procedure found in VPM
Instructions manuals.
c. Thoroughly clean all material that may be found
on the top of the platen.
d. Turn off all sources of power to the machine.
To avoid serious injury or machine damage, all
electrical connections need to be done by a qualified
electrician familiar with local codes.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
