The following table outlines the required characteristics for inlet water and inlet condensation water. If not provided in the supply, fit a mesh filter on the water inlet.

Please note that for special water types such as demineralized, deionized or distilled it is necessary to contact the manufacturer to verify which kind of chiller should be used since the standard material may not be suitable.

If the PARKER HYPERCHILL ICE310 is installed outdoors or in an unheated indoor area, the water in the circuit may freeze when not in operation. To avoid this, you can add an appropriate quantity of antifreeze (ethylene glycol) to the water in circulation. The required percentage depends on the outlet water temperature and ambient temperature.

Follow these steps to start the chiller:

1. Compressor Heating: Connect the power supply to the machine by turning the main isolator switch QS [P0] to ON. For the FL2 option, the crankcase heater must be activated 24 hours before starting the machine. Incorrect operation can damage the compressor.

3. Press the [P6] button. The message “OFF” appears with a flashing arrow.

4. Press the [P6] button again to confirm.

5. The chiller will stop, and the display will show “Status Unit : OFF”.

Warning: Do not turn off the main switch QS [P0] to ensure that any antifreeze protection devices will still receive electrical power.

Follow these steps to change the temperature set point:

1. Press the [P2] button to enter the “main” menu.

2. Press the [P5] button to scroll and select “DIrE”.

3. Press the [P6] button. The message “DIrE” appears.

4. Press the [P5] button. The first parameter shown is the set point (SEt – Temperature Control – Set Point).

5. Press the [P6] button to enter the parameter setting mode.

6. Press the [P4] or [P5] buttons to modify the value.

7. Press the [P6] button to confirm the new setting.

8. Press the [P3] button to exit (ESC).

The ON/OFF of the compressors depends on the water outlet temperature (b1) with reference to the “set” and “dif” parameters. The compressor ON/OFF logic also depends on the ambient temperature.

Example (ambient temp. <10°C, set = 7°C, dif = 4°C):

• when the water inlet temperature reaches 9°C (7 + 2): compressor 1 starts;

• when the water inlet temperature reaches 11°C (7 + 4): compressor 2 starts.

Example (ambient temp. >10°C, set = 7°C, dif = 4°C):

• when the water inlet temperature reaches 11°C (7 + 4): compressors 1 and 2 start.

Warning: A compressor can only restart after a stop of 6 minutes.

When the [P1] button is red, an alarm is present. Press the button to see the type of alarm (e.g., HP1 High pressure Alarm). To clear the alarm, you must first eliminate the cause of the fault and carry out the repair. After the repair, press the [P1] button again. If the message “noAL” appears, press [P1] one more time to reset the alarm.

Digital Input Alarms

* HP1/HP2: once the cause of the outage has been eliminated, there is a button on the pressure switch to press to reset the component, then it is necessary to perform the reset from the display; this type of intervention requires qualified and specialized personnel.

Analog Input Alarms

To guarantee lasting maximum chiller efficiency and reliability, carry out the following:

• Every 4 months: Clean the condenser fins and make sure compressor electrical absorption is within the dataplate values.

• Yearly – W version: In case of encrustations inside the condenser, introduce and circulate a specific detergent liquid.

During periodic maintenance, the electrical system on the machine and the electrical panel must also be checked in accordance with local legislation. Additionally, a visual inspection of the equipment and electrical conductors should always be performed where possible, and the correct tightening of the terminals of the power components must also be verified.

• Every 3 years: Installation of kit for maintenance every 3 years.

If the outlet water temperature exceeds the set value, it may be due to excessive water flow or a high thermal load. The remedy is to reduce the flow rate of the water being cooled.

If the compressor stops due to the operation of the high-pressure switch, check the following potential causes and apply the corresponding remedy:

• Cause: High ambient temperature. Remedy: Return the ambient temperature to below the specified limit.

• Cause: Condenser fins are dirty. Remedy: Clean the fins of the condenser.

• Cause: Condenser surfaces are clogged. Remedy: Clear the front surface of the condenser.

• Cause: Fan rotates backwards. Remedy: Swap over the phasewires.

• Cause: Pressure switch is broken or incorrectly calibrated. Remedy: Replace the pressure switch.

If the compressor stops due to the operation of the low-pressure switch, investigate the following potential causes and remedies:

• Cause: Refrigerant filter is clogged. Remedy: Renew the filter.

• Cause: Insufficient water flow. Remedy: Increase the flow rate of the fluid to be cooled.

• Cause: Thermostatic bulb is discharged. Remedy: Renew the valve.

• Cause: Thermostatic valve is incorrectly calibrated. Remedy: Recalibrate the valve.

• Cause: Leaks in the circuit, or the system is discharged. Remedy: Check for leaks, repair them, and charge the circuit.

A frosted compressor suction line can be caused by several issues. Check the following:

• Cause: Insufficient water flow. Remedy: Increase the flow rate of the fluid to be cooled.

• Cause: Thermostatic bulb is discharged. Remedy: Renew the valve.

• Cause: Thermostatic valve is incorrectly calibrated. Remedy: Recalibrate the valve.

If the compressor runs for long periods and is noisy, it could be due to one of the following reasons:

• Cause: Compressor components have deteriorated. Remedy: Repair or replace the compressor.

• Cause: The refrigerant filter is clogged. Remedy: Renew the filter.

• Cause: There are leaks in the circuit, or the system is discharged. Remedy: Check for leaks, repair them, and then charge the circuit.

The refrigerant and the lubricating oil contained in the circuit must be recovered in conformity with current local environmental regulations. The refrigerant fluid is recovered before final scrapping of the equipment.

Equipment containing electrical components must be disposed of separately and collected with electrical and electronic waste according to local and current legislation.
