Preventive Maintenance - Toshiba VP 300 Installation Instructions Manual

5.1

PREVENTIVE MAINTENANCE

Preventive maintenance consists of periodic visual inspection of fan operation, cleaning the air filter, and
listing the System Performance Tables. The frequency of this maintenance depends on the operating
environment provided for the VP 300. Based upon the environment, the local service company should
determine the maintenance interval required.
Use of a wrist grounding strap prevents damage to sensitive electronic components.
Before handling any electronic equipment, including the Power Supply Unit and cables,
attach one end of the strap around your wrist and the other end to any unpainted surface
of the VP 300 inner metal cabinet.
