ment parts or any other service calls or repairs. Products that are tampered with, damaged or defective due to malfunctioning appli-
ances are not covered under this warranty. This warranty DOES NOT cover the complete Power Venter if it is operative, except for
the defective part.

Tjernlund Products, Inc. will issue credit or provide a free part to replace one that becomes defective during the one year warranty peri-
