1:    When the ambient temperature or circulating fluid temperature is 10
 o
C or below, refer to "3.2.2 Operation at low ambient temperature or low 
circulating fluid temperature". 
2: Use fluid for circulating fluid that conforms to: 
Clean water: Water Quality Standards of the Japan Refrigeration and Air Conditioning Industry Association (JRA GL-02-1994) 
15 to 40% ethylene glycol aqueous solution: Diluted with clean water, without any additives such as antiseptics. (Refer to "3.2.2 Operation at low 
ambient temperature or low circulating fluid temperature" for the concentration of the ethylene glycol aqueous solution.) 
DI water (pure water): Electrical conductivity 1 μS/cm or more (electrical resistivity 1MΩ・cm or less)

6: With pressure control function using an inverter.  When the pressure control function is not being used, the pump power supply frequency setting 
function can be used. 
7: Required flow rate to maintain the cooling capacity.  When the flow rate is lower than the rated flow, use a by-pass piping set. 
8: The anchor brackets (including M8 bolt x 6pcs.) are used for fixation with the skid when this product is packed. The anchor bolts are not attached.
