SUBJECT:
Platinum Corona Wire
--When to install the platinum corona wires-
The platinum corona wires do not have to be cleaned as often as the tungsten wires
(point 1). For this reason, the platinum corona wires are most suitable in cases where a
machine is installed in a relatively inaccessible location (far from a service center) and
service calls are difficult to make.
The platinum wires can be installed in the field on the following models:

When installing the platinum corona wires, please take the following actions:
1. Clean the corona casings, end blocks, and new platinum wires with damp cloth.
2. Confirm VSG.
