tool horizontally.

ordinary household detergent. Wait 10 minutes then
proceed to step 4.
4. Using garden hose, spray coil vertically downw;ard
with a constant stream of water at moderate pressure
(see Fig. 33). Keep nozzle at a 15 to 20 degree angle,
about 3-in. (76 mm) from coil face and 18-in. (457 mm)
from tube. Spray so debris is washed out of coil and
heat sink.
