Air Filter/Regulator and Pressure Switch Replacement
Introduction
Purpose
This Field Service Bulletin describes the necessary steps to replace the air filter/regulator and pressure switch assembly
on Powermax30 power supplies.
This kit contains separate air inlet fittings for the Powermax30 and the Powermax30 XP. The fittings for the
Powermax30 XP will not work on the Powermax30 because they are too large to fit through the rear panel.
Powermax30 XP systems: Complete instructions for installing this repair kit are included in the Powermax30 XP
Service Manual (808150). To download the Service Manual, go to www.hypertherm.com and click the “Downloads
library” link.
Tools and materials needed
Assorted Phillips®and TORX®screwdrivers
1/2 inch wrench or adjustable wrench (CSA models only)
19 mm wrench or adjustable wrench (CE models only)
Thread sealant
WARNING!

Disconnect electrical power before performing any maintenance.
See the Safety and Compliance Manual (80669C) for more safety
precautions.
CAUTION!
