•
Use an appropriate work area and location when
performing repairs. You will find that it is easier to
repair undercounter units if they are set on a raised
platform or workbench.
•
Always wear protective safety glasses and gloves
when working on any Viking product.
•
Any refrigerant, whether CFC, HCFC, or HFC (R-12,
R-22, or R-134a), must be recovered. Federal
regulations prohibit the intentional venting or release
of refrigerants during the service repair or disposal
of an appliance.
