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: 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).

WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.

WARNING: BE CAREFUL WHEN YOU REMOVE OR INSTALL THIS EQUIPMENT. THIS EQUIPMENT IS HEAVY (MORE THAN 12 KG (26.5 lb)) AND CAN CAUSE INJURY AND/OR DAMAGE.
