Pump automatic running and stopping is repeated to prevent freezing by maintaining circulating fluid temperature at 3C to 5C. Pump automatically starts operating if the circulating fluid temperature drops below 3C. Circulating fluid is heated by the pump power generated by pump operation.

If the fluid temperature is less than 5C, the moisture in the circuit could freeze, causing damage to the seals and leading to equipment malfunction. Therefore, take appropriate measures to prevent freezing. Maintenance Operating environment Warning Warning 1. Follow the procedures given in the operation manual to perform a maintenance inspection.
Take measures to prevent freezing fluid when below 5C, since this may cause damage to the switch and lead to a malfunction. Never use the switch in an environment where there are drastic temperature changes even when these temperatures fall within the specified temperature range. Wiring Warning 1. Verify the color and terminal number when wiring.
Since moisture in the fluid can freeze when used at 5C or below, causing damage and malfunction of switches, consider measures to prevent freezing. The installation of an air dryer is recommended to remove drainage and moisture from circuits.

When the ambient temperature is 20C 5C and rated voltage is applied. Changing coils from AC to DC and vice versa is impossible, because of different core shapes. VXD21 0, 22 0, 23 0 are possible to exchange coil from AC to DC, but impossible from DC to AC. (Hum sound may generate because of no shading coil for DC.)
