After turning the Cooler on, you should see a temperature
drop of 17°C to 20°C (30.6°F to 36°F) within 30 minutes,
with a possible further decrease that levels off after about
an hour.
NOTE: The digital thermometer on the DSLR Cooler dis-
plays the internal temperature as “OUT” and the outside
(ambient) temperature as “IN” (Figure 10). We know, it’s
wacky!
2. After your imaging session, press the ON/OFF button
again to turn the Cooler off. You’ll know it is off when the
fan on the back of the housing stops rotating.
To prevent condensation from forming on the cold camera,
it is best to either:
a. Leave it in the closed Cooler for a half hour or so
before removing it, to allow the camera to warm up
slowly, or
b. Remove it from the Cooler while still outside and
immediately place the camera into a plastic bag and
seal it. (A large zip-lock freezer type food storage
bag is ideal.) This way the condensation will form on
the plastic bag, not on the camera itself.
Power Consumption
Drawing 3.7 to 4 amps of current, the DSLR Cooler requires
lots of power. We recommend running it on at least a 30
amp-hour (AH) deep-cycle marine battery or, if possible, on
household 110V power via an AC-to-12V DC adapter rated
for at least 4 amps (both sold separately). A 30AH battery
will provide power for up to 7.5 hours of continuous opera-
tion, theoretically (30AH ÷ 4A = 7.5H); a 55AH battery will
allow nearly 14 hours of continuous operation.
We do not recommend use of the Orion Dynamo Pro 12AH
or 17AH batteries, since they would power the DSLR Cooler
for only about 3 or 4 hours, respectively, on a full charge.
Figure 10. On the LCD temperature gauge, the IN reading
is really the outside temperature and the OUT reading is the
temperature inside the Cooler! That’s what happens when you
repurpose an indoor/outdoor car thermometer.

from the ceiling of the housing.

with cables passing through the cable collar. The cable plugs are a
tight fit!
