Freezing point/°C
Mantenere asciutto
If no glycol is added, the water must be drained out when there is a power failure.
Water may enter into the flow switch and cannot be drained out and may freeze when the temperature is low enough.
The flow switch should be removed and dried, then can be reinstalled in the unit.
WARNING
Ethylene Glycol and Propylene Glycol are TOXIC
The concentrations mentioned in the table above will not prevent freezing, but will prevent the hydraulics from bursting.
NOTE
CounterclockWise rotation, remove the flow switch.
Drying the flow switch completely.
CAUTION
Use of glycol
Glycol use for installations with a domestic hot water tank: Only propylene glycol having a toxicity rating or class of 1, as listed in
"Clinical Toxicology of Commercial Products, 5th edition" may be used. The maximum allowed water volume is then reduced
according to the figure on page 45.
If there is too much pressure when using glycol, connect the safety valve to a drain pan to recover the glycol.
