When you are done adding RV antifreeze:
1.
Turn the water pump OFF. Turn siphon valve OFF. Remove the clear hose from the
container of RV antifreeze. Leave the water tank shutoff valve (Valve E if equipped)
closed to keep antifreeze out of the fresh water tank. See Water Heater Bypass Dia-
gram.
2.
Pour 1 cup of RV antifreeze into the sink drain P-trap.
3.
To prevent staining, wipe the RV antifreeze out of the sinks, shower (or tub) and toilet
using a soft, dry cloth.
De-winterize the macerator system: Emptying the black tanks in the spring will flush
antifreeze out of the macerator system.
NOTE: In the spring when flushing antifreeze out of the water lines
make sure to turn the water tank shutoff valve back ON. After flush-
ing out water lines the water filter should be re-installed.

the water begins to flow. Hydrogen gas may be present even after water
has been drained from the water heater tank. Open the faucet at the sink
and allow the system to vent for five to ten minutes. Do not smoke or
have any open flame near the open faucet while venting. On DSI water
heater models, make sure the switch is OFF.

on your water heater. Accessories marketed for recreation vehicles, such
as an "add-on" electric heating elements, are not recommended by the
