Site Survey, Installation & Commissioning


Site Survey – preliminary installation check

A professional preliminary inspection of the installation conditions avoids surprises on the day of installation. One of our Service Technicians will carry out a full site survey to ensure all the correct services are in place prior to installation; such as electric, gas and water supply, including adequate drainage and waste disposal.

  • A site survey provides the basis for trouble-free installation, avoiding delays and unnecessary extra costs.
  • Using an accredited RATIONAL Service Partner protects the warranty of your RATIONAL unit, as all site surveys and installations adhere to RATIONAL standards and specifications.
