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.

Power Requirements

A 25A (minimum) - 30A (maximum) circuit breaker must be installed on the incoming power supply.

*Add to power requirements of ExactaBlend AGP Advanced Glazing Proportioner system. Amps maxi- mum per leg shown.

**190-264 voltage range acceptable.

Installation

To avoid serious injury or machine damage, all electrical connections need to be done by a qualified electrician in compliance with local codes.

Grounding

Ground the system as instructed within this manual.

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.

Maintenance

Platen Maintenance

Remove and Reinstall Platen Wipers

Refer to Supply Units Repair-Parts manual for instruc- tions.

If the platen does not come out of the pail easily when the pump is being raised, the air assist tube or check valve may be plugged. A plugged valve prevents air from reaching the underside of the plate to assist in raising it from the pail.

1.Turn off main disconnect at the machine.

2.Allow equipment to cool.

3.Relieve pressure and disassemble air assist valve. Refer to Supply Systems Repair-Parts manual.

4.Clear air assist tube in platen. Clean all parts of valve and reassemble. Refer to Supply Systems Repair-Parts manual.

5.Remove bleed stick from platen. Push bleed stick through bleed relieve port (P) to remove material residue. See FIG. 3.

6.Remove platen covers. See FIG. 3.

a.Remove platen cover fasteners (F).

b.Remove both platen covers (C) and ground wire from platen.

7.Remove any excess fluid. Use a soft wire brush on heater coils (H). See FIG. 3.

8.Inspect platen heater blocks (B) or heater (H) for burn or melt spots. Replace platen heater if neces- sary. See FIG. 3.

9.Check for loose connections and damaged wires.

10.Follow steps in reverse order to reassemble platen.

NOTE: Torque platen cover fasteners (F) to 60 +/- 10 in-lbs (6.8 +/- 1.1 N???m) for 55 gallon platen.
