Next, familiarize yourself with the features and components
of the DSLR Cooler in Figure 2.
Compatible Cameras
At the time of this manual’s writing, the following Canon EOS
cameras are known to be compatible with the DSLR Cooler:
350D (XT) 550D (T2i)
400D (XTi) 1000D (XS)
450D (XSi) 1100D (T3)
500D (T1i)
Other Canon models and other brands of DSLR may not fit
physically in the Cooler due to their overall size or propor-
tions, or to the position of their lens opening relative to the
¼"-20 mounting hole on the bottom of the camera.
Installing the Camera in the DSLR Cooler
This section describes installing your compatible Canon
DSLR camera in the DSLR Cooler with a DC coupler, USB
cable, and shutter control cable, all of which are sold sepa-
rately.
1. Disassemble the two parts of the cooler housing by
unscrewing the four plastic connecting screws using a
flat screwdriver.
2. Attach a T-ring (sold separately) to your camera.
Before installing the camera in the cooling chamber, you
will need to insert the DC power coupler into the battery
compartment and attach all necessary cables to the
camera. We recommend powering the camera with an
external power source via a “DC coupler” (fake camera
battery) designed for your particular camera model
rather than the standard internal battery, for several
reasons:
a. Batteries lose charge faster in cold conditions, so
the internal battery may not last for an entire imaging
session before needing replacement or recharging.
An external marine cell battery or AC power source
has plenty of extra capacity to keep your camera
powered on continuously for extended periods of
time.
b. It is not possible to swap a discharged internal
battery with a fresh one without opening up the
cooler housing.
c. You won’t be able to see the battery charge indicator
on the camera’s LCD screen to know when the
battery is about to die!
3. Remove the plastic cable collar from the housing by
pushing it with a finger from the inside while pulling it
from the outside. You may have to twist it or rock it a bit
to dislodge it.
4. Insert the USB, shutter control, and DC coupler cables
through the hole in the housing (Figure 3a). Then, insert
the USB and shutter control plugs into your camera
and install the DC coupler in the battery compartment
(Figure 3b).
5. Now attach the camera to the floor of the cooling
chamber. Line up the threaded socket in the bottom
of the camera with the ¼"-20 stud in the bottom of
the housing. When they are lined up, the T-ring on the
camera should be positioned snugly within the circular
opening of the housing (Figure 4). Now thread the stud
Figure 4. With the camera installed, the T-ring on the camera
should be seated snugly in the aperture port of the housing.

coupler and other cables into the camera before installing the camera in the cooling chamber
