WARNING: Failure to follow these safety instructions may result in personal injury or damage to the equipment.

• Feu funcionar la unitat sempre sobre una superfície estable i anivellada.
• Assegureu-vos que hi hagi una ventilació adequada al voltant de la unitat per evitar el sobreescalfament.
• Do not operate the unit without proper fluid levels in the bath.
• Use only recommended heat transfer fluids. Consult the fluid manufacturer's safety data sheet (SDS) for handling precautions.
• Desconnecteu l'alimentació abans de realitzar qualsevol manteniment o neteja.
• Avoid direct contact with heated or cooled fluids and surfaces.
• Do not immerse the controller or electrical components in fluid.
• Ensure the power supply matches the unit's requirements (120V/60Hz).

3. Desembalatge i configuració

3.1 Desembalatge

Carefully remove the unit from its packaging. Inspect for any signs of shipping damage. Retain packaging materials for future transport or storage.

3.2 Col·locació

Place the circulating bath on a sturdy, level surface. Ensure there is sufficient clearance (at least 15 cm or 6 inches) around all sides for proper air circulation, especially for the WhisperKool Environmental Control System and Cool Command modulated refrigeration system. The unit's dimensions are approximately 21.3"D x 8.7"W x 25.4"H.

3.3 Fluid Filling

The bath has a 7-liter capacity. Fill the bath with the appropriate heat transfer fluid (e.g., distilled water, ethylene glycol/water mixture, silicone oil) to a level between the minimum and maximum fill lines. Ensure the fluid level is sufficient to cover the pump and heating/cooling coils.

3.4 Connexió d'alimentació

Connect the power cord to a grounded electrical outlet (120V/60Hz). Ensure the power switch is in the OFF position before connecting.

4. Instruccions de funcionament

4.1 MX Controller Overview

The MX Controller features a large, universal icon and English display for easy readability. It provides intuitive control over temperature settings and operational parameters.

4.2 Configuració de la temperatura

1. Enceneu l'interruptor principal.
2. The display will show the current bath temperature and the setpoint temperature.
3. Use the arrow keys on the controller to adjust the setpoint temperature to your desired value within the range of -20°C to 135°C.
4. Press the ENTER key to confirm the new setpoint.
5. The unit will begin heating or cooling to reach the setpoint. The Cool Command modulated refrigeration system will optimize cooling performance.

4.3 Calibració

The MX Controller offers single-point calibration capability. Refer to the detailed controller manual for specific instructions on performing calibration to ensure temperature accuracy.

5. Manteniment

5.1 Fluid Management

• Regularly check the fluid level and replenish as needed to prevent damage to the pump or heater.
• Change the heat transfer fluid periodically (e.g., every 3-6 months, depending on usage) to maintain optimal performance and prevent algae growth or contamination.

5.2 Neteja

• Exterior: Netegeu les superfícies exteriors amb adamp drap i detergent suau. Eviteu els netejadors abrasius.
• Bath Tank: Drain the bath and clean the interior with a non-abrasive brush or cloth. Rinse thoroughly with distilled water.
• Condensador: Periodically clean the condenser fins (located on the side/rear) with a soft brush or vacuum cleaner to ensure efficient refrigeration.

5.3 Emmagatzematge

If storing the unit for an extended period, drain all fluid from the bath and ensure it is clean and dry. Store in a clean, dry environment.
