NOTICE:

Check around the quick connector for dirt or mud be-
fore this operation. Remove the dirt if necessary.

Be careful of mud because the quick connector has
an O-ring which seals the pipe and quick connector
that can be contaminated.

Do not use any tools in this operation.

Do not bend or twist the nylon tube. Protect the quick
connector by covering it with a vinyl or plastic bag.

When the pipe and quick connector are stuck, push
and pull the quick connector to release and pull the
quick connector out carefully.
(b) Disconnect the heater inlet water hose.
