7.3.1 Draining of Circulating Fluid Out of Tank

Use the clean container for circulating fluid recovery. Reuse of the
recovered circulating fluid with contaminated will cause insufficient cooling
and system failure.
Be sure to wait until the circulating fluid obtains room temperature for its
draining. Potential burns and dew intrusion may occur if disregarded.
1 Prepare the container for circulating fluid recovery at the back of this system.
2 Connect the drain hoses to the main and sub
tank drain ports each. Insert the tip of the hose
into the container.
Prepare a drain hose (Rc3/8-diameter) on your
responsibility.
3 Remove the cap of the circulating fluid fill port
4 Open the valves of the main and sub tank drain ports to drain the circulating fluid.
5
Apply air purge from the the circulating fluid return to push the circulating fluid
remaining in the heat exchange back in the tank and drain it.
If the recovered circulating fluid is contaminated by foreign substances,
completely remove them. Do not reuse comtaminated fluid.
Potential insufficient cooling, system failure and froth in the circulating
fluid may occur if disregarded.
Recovered circulating fluid must be sealed in a container to prevent
contamination from moisture or foreign substances.
Stored in a cool, dark place. Keep it from flame.
