 The electrical facilities should be installed and wired in accordance

with local laws and regulations of each country and by a person who has knowledge and experience.

 Check the power supply. Operation with voltages, capacities and

frequencies other than the specified values can cause fire and electric shock.

 Wire with an applicable cable size and terminal. Forcibly mounting

with an unsuitably size cable may result in heat generation or fire.

Be sure to connect the power supply cable from the product side first,

and then connect the breaker of the facility power supply (the user’s

machine power supply).

 When the panel is removed or mounted, be sure to wear protective

shoes and gloves to prevent injury with the edge of the panel.

4.3 Preparation of Circulating Fluid Supply to User’s Equipment

Circulating fluid is supplied only inside of the product at the time of installation of the thermo-chiller.

When the product starts operation in this condition, circulating fluid level will be reduced as the fluid in the level gauge goes down due to the fluid supply to the user's equipment from the thermo-chiller, and the additional fluid needs to be supplied to the thermo-chiller.

Follow the instructions below to supply additional fluid:

1. Press the [PUMP] key on the operation panel (press the [RUN/STOP] key and [MENU]

key simultaneously).

The pump operates independently while the [PUMP] key is being pressed. The [RUN] light (green) blinks while the pump is operating independently and the circulating fluid in the tank is supplied to the user’s equipment and piping. This finds out leakage from the piping as well as discharges air from the piping. If the fluid level in the tank reaches the lower limit, a buzzer will be generated, and the alarm number “AL01 (low level in tank)” is displayed as PV on the digital display. The [ALARM] light (red) blinks, the [ ] light turns ON, and independent operation of the pump stops. For alarm reset, refer to step 2.

 This function can be activated only when the power supply is ON

and the thermo-chiller is not operating.

 Fully open the valve or manual bypass valve that is arranged by the

user to make it possible for the circulating fluid to circulate when the pump starts automatic operation.

 In extremely cold weather, the heat generated by the pump

operation may not be enough to prevent freezing of the circulating fluid.

 During the automatic operation, the pump does not stop even if the

"RUN/STOP" key is pressed. To stop the pump, turn the power supply OFF or turn this function OFF.

 This function does not prevent the automatic water fill circuit from

being frozen. Countermeasures against freezing of the automatic water fill circuit should be taken with the user's equipment.

Keep the power supply ON for this function. This function does not start when the power is OFF.

5.11 Anti-freezing Function

5.11.1 Anti-freezing function

This function prevents freezing of the circulating fluid while the product stops operation in the winter season with heat generated by automatically operating the pump.

When there is a possibility of the circulating fluid freezing due to changes in the installation or operating environment (e.g. season, weather), set this function ON in advance.

● If the circulating fluid temperature falls down to 3 oC or less, the pump starts operation automatically.

● Heat generated by the pump operation warms up the circulating fluid. When the circulating fluid temperature reaches 5 oC or higher, the pump stops operation automatically.

● Repeated automatic operation start and stop of the pump maintains the circulating fluid temperature to 3 oC to 3 oC to prevent the circulating fluid from being frozen.

HRX-OM-Q026

When the anti-freezing function is set ON, the [RUN] light blinks every 2 seconds while the pump is in the standby state (while the pump stops operation). The [RUN] light blinks every 0.3 seconds during the automatic operation of the pump. The default setting of this function is “OFF”.

This function does not prevent the automatic water fill circuit from being frozen. Countermeasures against freezing of the automatic water fill circuit should be taken with the user's equipment.

Note that when the warming up function is ON, the warming up function has a priority over the anti-freezing function, and the anti-freezing function will not be activated. (See “5.18 Warming Up Function”)
