For ambient temperatures below 5° C (40° F), it is necessary to add ethylene glycol to
the water of the circuit.
The required ethylene glycol concentration is obtained according to the following chart.
Ambient temperature
Percent ethylene glycol
The ethylene glycol percentage of the total mixture, by weight, is given in the chart.
If any water is added to the mixture, the concentration of ethylene glycol should be
checked.
CAUTION Do not use automotive antifreeze. Use lab grade ethylene glycol, or refrifluid only! Do not use
an ethylene glycol concentration above 30 percent—this would damage the water pump.
