5. Insert the CS705 antifreeze reservoir into the rain gage funnel.
Wear safety glasses during handling and pouring of
antifreeze. CAUTION
6. Fill the reservoir with PGE antifreeze (pn 10869) until a small amount
flows out the overflow tube. The reservoir holds ≈2.5 gallons.
7. Add ≈8 ounces of a low-freezing-point, environmentally-safe oil to the
antifreeze reservoir. This oil prevents the antifreeze solution from
evaporating. The oil should cover the entire liquid surface. Some
unscented baby oils (lightweight mineral oil) work well.
8. Stretch the second black band over the lip of the antifreeze reservoir.
9. Insert the catch tube into the antifreeze reservoir.
10. Reposition the two black bands to cover the joints between the catch tube
and the antifreeze reservoir and between the reservoir and the rain gage
funnel.
