Cleaning of Vacuum Waste Lines with Waliclean Recirculation Cleaning Tool

WARNING: ALWAYS USE RUBBER GLOVES WHEN YOU DO WORK:
  • ON THE TOILET WASTE SYSTEM, OR
  • ON PARTS THAT HAVE CONTAMINATION FROM THE WASTE SYSTEM.
WHEN YOU COMPLETE THE WORK PROCEDURE, CLEAN YOUR HANDS WITH SOAP AND WATER. THIS WILL PREVENT INFECTION (TOILET WASTE IS DANGEROUS FOR HEALTH).
