  1. How do I obtain technical assistance?

    • Contact you local distributor. The distributor has a Service Coordinator who will be able to provide technical assistance on a local basis.
    • If the Distributor Service Coordinator is not available you must have a representative from the distributor place a conference call to the Call Center. With the Distributor Representative involved with the call a technician will offer assistance.
  1. What information is required for prompt technical assistance?

    • The complete model and serial number of the equipment in question.
    • A accurately completed Job Site Information Sheet on the product in question is the first step. The information in these sheets will help the Inside Technical Representative determine possible solutions.
    • Provide information regarding the installation of the equipment.
  1. What is a triple evacuation?

    • Higher efficiency equipment, much like a modern automobile is a complex system where everything must be finely tuned.
    • A triple evacuation begins with the installation or replacement drier and a good vacuum pump with fresh oil.
    • The technician will perform a deep vacuum, down to 500 microns. He will then break the vacuum with nitrogen. The nitrogen will then be released and another deep vacuum will be pulled to 500 microns again. Once more the vacuum will be broken with the nitrogen. A third and final vacuum will be pulled, again to 500 microns. This time the vacuum will be broken with refrigerant.
