The following table outlines the required water characteristics. 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 installed outdoors or in an unheated indoor area, the water in the circuit may freeze. To avoid this hazard, 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 the ambient temperature.

Before carrying out any operation on the electrical system, make sure that the appliance is disconnected from the electrical power supply. All electrical connections must comply with the applicable regulations in force in the country of installation.

Initial Checks

1) The power supply voltage and frequency must correspond to the values stamped on the chiller nameplate. The power supply characteristics must not deviate from the tolerance limits indicated on the electrical diagram (+/- 10% for voltage; +/- 1% for frequency).

2) The power supply must be symmetrical (effective voltages and phase angles of consecutive phases must be equal). The maximum permissible voltage imbalance is 2%.

Connection

1) The electrical power supply must be connected using a 4-wire cable (3 phase conductors and an earth conductor, with no neutral).

2) Pass the cable through the cable entry on the rear panel and connect the phase and neutral to the terminals of the main isolator switch (QS); connect the earth wire to the earth terminal (PE).

3) Ensure that the supply cable has at its source protection against direct contact of at least IP2X or IPXXB.

4) On the supply line, install a residual-current circuit breaker with a trip rating of 0.3A, with the current rating indicated in the reference electrical diagram, and an appropriate short circuit current rating. The nominal current (In) of the magnetic circuit breaker must be equal to the FLA with an intervention curve type D.

5) The maximum grid impedance value is 0.274 ohm.

Subsequent Checks

Check that the machine and auxiliary equipment are earthed and protected against short circuit and/or overload.

LED Indicators:

Attention: Wait for the “30 seconds” boot start up to complete.

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.

2. Start Procedure:

1. Switch on and wait for the “Status Unit: OFF” screen to appear.

2. Press the P2 button to enter the “main” menu.

3. The “Main menu” will appear. “On” should be selected.

4. Press the P6 button. The message “ON” will appear.

5. Press the P6 button again and the arrow will start flashing.

6. Press the P6 button one last time to start the chiller.

a) Temperature setting: To adopt a new setting, see heading 4.5.

b) Verify pump operation: Use the pressure gauge (read P1 and P0) and check the pressure limit values (Pmax and Pmin) on the pump data plate. The condition Pmin < (P1-P0) < Pmax should be met.

c) Verify correct pump operation under normal running conditions and check that the amperage is within the limits on the data plate.

d) Top up hydraulic circuit: Switch off the chiller and top up the hydraulic circuit at the “SET” temperature.

e) Check temperatures: Ensure the “treated” water temperature does not fall below 5 °C and the ambient temperature does not fall below 5 °C. If necessary, add glycol as explained in section 3.4.2.

1. From the main operating screen, press the P2 button to enter the “main” menu.

2. Use the P5 button to scroll down and select “OFF”.

3. Press the P6 button. The message “OFF” appears on the screen.

4. Press the P6 button again, and the arrow will start flashing.

5. Press the P6 button one final time to stop the chiller. The status will change to “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.

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

2. Use the P5 button to scroll down and select “DIrE”.

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

4. Use the P5 button to select the first parameter, which is the set point (“SEt Temperature Control Set Point”).

6. Use the P4 (up) or P5 (down) buttons to modify the value.

7. Press the P6 button to confirm the new value.

8. Press the P3 (Esc) button to exit.

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):

If set = 7°C and dif = 4°C, when the water inlet temperature reaches 9°C (7 + 2), compressor 1 starts. When it reaches 11°C (7 + 4), compressor 2 starts.

Example (Ambient temp. > 10°C):

If set = 7°C and 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 Circuit 1).

To clear the alarm, you must eliminate the cause of the fault and carry out the necessary repair. After the repair:

1. Press the P1 button.

2. If the message “noAL” appears, press the P1 button again to reset the alarm.

* 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.

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.

• Every 3 years: Installation of kit for maintenance.

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

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

If the compressor stops due to the high-pressure switch, check the following potential causes and remedies:

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

• Condenser fins dirty: Clean the fins of the condenser.

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

• Fan rotates backwards: Swap over the phase wires.

• Leaks in circuit, system discharged: Check for leaks, repair, and charge the circuit.

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

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

• Refrigerant filter clogged: Renew the filter.

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

• Thermostatic bulb discharged: Renew the valve.

• Thermostatic valve incorrectly calibrated: Recalibrate the valve.

If the compressor suction or liquid line is frosted, it may be due to a clogged refrigerant filter. The remedy is to renew the filter.

If the compressor runs for long periods and is noisy, it could indicate that the compressor components have deteriorated. The solution is to repair or replace the compressor.
