Antifreeze of circulating fluid

This unit is resistant to freezing of the circulating fluid during wintertime and nighttime.

Ensure the following measures are taken in advance if potential frost damage may occur in response to changes in the installation and use environments (including operating period and weather).

1. Leave the power on (the [POWER] lamp remains on, and the [RUN] lamp remains off).

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.

zContact 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 unit (such as a commercial tape heater).
