(4) Handling of the circulating water cooler
Handle the circulating water cooler and the cooling water according to an instruction
manual of the circulating water cooler.
Proper performance may not be achievable if a non-recommended circulating water
cooler is used.
(5) Start water cooling and water cooping in operation
• Confirm the water is flowing before starting the camera cooling and that the camera
does cool.
• Keep 1.0 L/min flow rate for water circulation.
• Do not stop coolant while the camera is working.
(6) Cooling water hose
The hose has a blue hose (Internal diameter: 4 mm / External diameter: 6 mm) and a
gray hose (Internal diameter: 8 mm / External diameter: 13.5 mm). (Figure 8-1)
If the hose size on circulating water cooler is the same as blue hose, remove gray hose
from the joint part. The gray hose can be removed when blue hose is pulled with
pushing the button of the joint on gray hose. (Figure 8-2)

power of the camera and the circulating water cooler.
• Confirm that cooling water stops.
• Prepare water absorption sheet (such as Waste, Towel or so) and catch pan in order
to avoid water drop or water splash.
(8) Deterioration of the cooling water hose
Replace the water hose with a new one whenever it cannot keep the Keep 1.0 L/min
flow rate for water circulation due to the hose deterioration.
