8. Maintenance

The CS705 requires regular site visits. The number of required visits mainly

depends on snowfall. Frequent or heavy snows require more site visits.

During site visits, verify the slot in the top of the overflow tube is free from ice

or debris and remove any debris from the catch orifice. If the slot in the

overflow tube becomes plugged, the overflow tube may create a siphon and

draw down the antifreeze level.

The PGE solution gets diluted as precipitation is captured and mixed. Initially,

the CS705 is charged with a pure antifreeze mixture giving it a 1:0 antifreeze to

water ratio. The ratio increases to 1:1 with the equivalent of six inches of

liquid, 1:2 with eight inches, and 1:3 with nine inches. The 1:1 solution

becomes slushy at a temperature of ≈–35°C, the 1:2 solution becomes slushy at

≈–20°C, and the 1:3 solution at ≈–10°C (McGurk, 1992). Ratios greater than

1 2 ... 10 11 12 13 14 15 16 17 18 19 20 ... 27 28
