belt (part # 4612) supplied with the climate control devices,
or the 36501 vinyl belt which may be ordered separately.
1. Determine whether the climate control device will be
worn vertically or horizontally on the waist.
2. If the device will be worn in the horizontal position, align
the tube on the heat shield as shown in Figure 3. If the
tube will be worn in the vertical position, align the tube
on the heat shield as shown in Figure 4.
3. Lace the belt supplied with your climate control device
through both the heat shield slots and the climate control
belt bracket slots.

Air Supply Hose
To maintain proper cooling to the vest, use Bullard V10 Series airline hose(s) in lengths of 25 ft. to 300 ft. or Bullard
V5 Series airline hose in lengths of 25 ft. and 50 ft. between the cool tube’s quick-disconnect fitting and the point-of-
attachment to the air supply. Bullard V11 hose-to-hose adaptors may be used to connect V10 hose lengths together.
Secure the connections until they are wrench tight.
NOTE: COMPRESSED AIR MUST BE DRY ENOUGH TO PREVENT ICE BUILDUP IN COLD AIRSTREAM. ICE
COULD HAMPER THE PERFORMANCE OF THE COOLING SYSTEM.
