YELLOW JACKET®

BRUTE™ II Test & Charging Manifold

OWNER’S MANUAL

Due to the unusually high pressures and hazardous gasses used in refrigeration and air conditioning, only TRAINED refrigeration and air conditioning technicians should use this equipment. Proper procedures must be used.

Section 608 of the Federal Clean Air Act requires that all persons who maintain, service, repair, or dispose of appliances must be certified since November 14, 1994. Failure to comply can cost you and/or your company as much as $25,000 per day, per violation. The EPA also offers a reward up to $10,000 for providing information concerning violations to the Act.
