4.3.1 Preparation of circulating fluid
 When the circulating fluid is a 60% ethylene glycol aqueous solution
Always check the concentration of the circulating fluid.
 When the circulating fluid is a fluorinated fluid
 When the circulating fluid is water

Circulating fluids to use vary with system models.
See section 8.1.1 “System specification” in Chapter 8 for the
designated circulating fluid for a specific model.
 Low concentration EG in the circulating fluid may cause system failure due to it being
frozen in the system.
 High concentration EG in the circulating fluid may cause circulating pump overload,
which triggers “Pump Breaker Trip FLT”.
 Potential cooling error may occur if the circulating fluid varies in concentration.
Make sure of no oil, moisture, and other foreign materials contaminate the
circulating fluid. Potential cooling error or system failure, due to contaminant
freezes internally, may occur if disregarded.
Attention should be taken on water quality. Ensure water quality is within specified
range, and other foreign materials contaminate the circulating fluid. Potential
cooling error or system failure, due to contaminant freezes internally, may occur if
disregarded.
