hose included with your RV.

Close the fresh water tank shutoff valve (if so equipped). Valve should be located in the
vicinity of the water pump. Open siphon valve on the water pump with the clear hose
attached and insert the opposite end of the clear hose into a container of RV antifreeze

tor system. When winterizing the RV, antifreeze must be added to the macera-
tor system.

In order to create a suction all low point drains must be
closed.
NOTE:
Antifreeze should never enter the water heater, RV water
filter, refrigerator, refrigerator water filter, or fresh water tank.
Automotive antifreeze (ethylene glycol) and windshield washer antifreeze
(methanol) are poisonous. Never use these products in your fresh water sys-
tem. These products are harmful and may be fatal if swallowed.
