All,

The freon115 cylinder is approaching empty and it is time to switch to
freon22. If the pressure gauge is to be believed, the gas will run out
in five weeks. I wish to switch to freon22 on May 23 and avoid any
unscheduled gas outages. Please plan accordingly. Etch testing on
freon22 has been completed and is awaiting Jim McVittie's blessing.

Thanks,

Dick
