2. Fully open valves laid with pipes on your unit to allow the circulating fluid to flow upon

automatic pump operation.

 Antifreeze function (automatic pump operation)

(1) After performing steps 1.and 2., automatic pump operation takes place when the circulating

fluid drops 3°C or below.

(2) The circulating fluid is heated by pump power output.

The pump comes to an automatic stop when the circulating fluid reaches 5°C or higher.

(3) The circulating fluid is allowed to be in the 3- to 5-°C range in temperature that is resistant to

freezing.

z Contact expert engineers.

Complete prevention of freezing the fluid may if the unit is installed
in an intensely cold place.
The above usage conditions require an addition of other antifreezing
