following procedure:

1. Heated applicators: disconnect and lock out input electrical power from the applicator.

NOTE: Do not remove the module from the regulator body or applicator adapter body

unless applicator location prohibits easy access.

2. If location requires the AG900+/AG900+S module to be removed from the regulator or

adapter block to access components, do so by removing the two socket head screws

from the front of the module and pulling it free.

NOTE: Module must be pulled straight away to avoid damage to locating dowel pins

on back face of module.
