GENERAL

  • What services and support does Mitsubishi Electric Critical Power Solutions offer?
  • How often does my Mitsubishi Electric UPS and/or DX Cooling System need preventive maintenance?
    • To ensure optimal performance and functionality, we recommend a bi-annual preventive maintenance schedule for both systems.
  • I want to get the most out of my investment. How do I setup a maintenance schedule for my Mitsubishi Electric UPS or Cooling System?
    • Specific site requirements can vary. The best way is to consult with one of our Service Coordinators by submitting your inquiry here.
  • Will there be downtime when preventive maintenance is being performed on my Mitsubishi Electric Uninterruptible Power Supply?
    • In most cases, there will not be; however the UPS will likely be on utility power while the maintenance is in progress. If there is an external maintenance bypass with your system, we can place your critical load on generator or utility power during our annual preventive maintenance visit. Additionally, we can offer after hours service in a maintenance contract for a modest upcharge if needed.
  • Will there be downtime when preventive maintenance is being performed on my Mitsubishi Electric wall-mounted cooling system?
    • Yes. Maintenance will require some downtime as our Service Technicians need to do full checks and cleaning that requires the system to be shutdown.
  • Does Mitsubishi Electric Critical Power Solutions have Service Technicians across the United States?
    • Yes. We have Service Technicians throughout the United States in strategic areas to provide fast response time.

  • Do you have technicians in countries other than the United States?
    • Yes. We also have technicians in Canada and partners in Latin and South America. To find your local technician, give us a call at 800-887-7830.

 

PRODUCT LIFECYCLE MANAGEMENT & SPARE PARTS
