Cleaning of the Toilet Waste Lines with CELESTE Recirculation Cleaning Tool
WARNING:
MAKE SURE THAT YOU PUT ALL WATER SAMPLES IN SAMPLING CONTAINERS WHICH THE LABORATORY SUPPLIES. THESE SAMPLING CONTAINERS ARE SPECIALLY PREPARED TO DO MICROBIOLOGICAL TESTS. IF YOU DO NOT USE THE CORRECT CONTAINERS, THIS CAN CAUSE INCORRECT LABORATORY RESULTS. THUS IT WILL NOT BE POSSIBLE TO KNOW THE LEVEL OF CONTAMINATION IN THE POTABLE WATER SYSTEM.
WARNING:
WHEN YOU REMOVE A COMPONENT OF THE TOILET WASTE SYSTEM, ALWAYS DISINFECT THE PART BEFORE YOU PUT IT IN A PLASTIC BAG, THEN SEAL THE BAG.
DO NOT PUT DOCUMENTS INTO THE PLASTIC BAG. SEAL THE BAG FIRST,THEN ATTACH THE DOCUMENTS TO IT.
THIS WILL PREVENT INFECTION OR ILLNESS. CONTAMINATION FROM THE WASTE CAN BE DANGEROUS TO HEALTH.
WARNING:
DO NOT DO WORK ON THE TOILET WASTE SYSTEM AND THE POTABLE WATER SYSTEM AT THE SAME TIME. THIS WILL PREVENT CONTAMINATION OF THE POTABLE WATER SYSTEM. SUCH CONTAMINATION CAN BE DANGEROUS TO HEALTH.
WARNING:
BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
CAUTION:
USE ONLY THE SPECIFIED MATERIALS AND OBEY THE INSTRUCTIONS FROM THE MATERIAL MANUFACTURERS. OTHER MATERIALS CAN CAUSE DAMAGE TO THE SURFACE PROTECTION OF THE COMPONENTS AND THE RELATED AREA.
NOTE: Tasks 38-31-00-100-004, 38-31-00-100-015, 38-31-00-100-019 and 38-31-00-100-804 are alternative and interchangeable cleaning procedures to task 38-31-00-100-803.
