4. Setup and Installation

The SRK-12J3 Remote Condenser is intended for installation away from the ice maker. Proper installation is crucial for optimal performance and longevity.

4.1 Site Preparation

• Ensure the installation location provides adequate ventilation and clearance for airflow.
• The surface must be level and capable of supporting the unit's weight.
• Consider the distance from the compatible ice maker (KMS-1122MLJ-3).

4.2 Refrigerant Line Installation

• Brazing and refrigerant charging are required for installation. This must be performed by a certified refrigeration technician.
• Tubing kits (25', 35', 55' lengths) are sold separately and must be selected based on the required distance between the condenser and the ice maker.
• For installations exceeding the standard tubing kit distances, contact Hoshizaki Technical Support for guidance.
• The unit uses R-404a refrigerant, with a charge of 15 lbs. 14 oz. (7200 g).

4.3 Electrical Connection

• The SRK-12J3 operates on Three Phase, 230V/60Hz power.
• The unit must be hardwired at the installation site. A 4-wire connection, including ground, is required.
• If a neutral wire is not available at the installation site, a transformer kit (Hoshizaki part number HS-5030) is required.
• All electrical work must comply with local and national electrical codes and be performed by a licensed electrician.

5. Operating Instructions

Once properly installed and connected to a compatible Hoshizaki ice maker, the SRK-12J3 Remote Condenser operates automatically in conjunction with the ice maker. There are no user-adjustable controls on the condenser itself. Ensure the area around the condenser remains clear of obstructions to allow for proper airflow and efficient heat dissipation.

6. Maintenance

Regular maintenance is essential to ensure the long-term performance and efficiency of your Hoshizaki SRK-12J3 Remote Condenser. All maintenance procedures should be performed by qualified service personnel.

6.1 Routine Checks

• Condenser Coil Cleaning: Periodically inspect and clean the condenser coils to remove dust, dirt, and debris. Blocked coils reduce efficiency and can lead to increased energy consumption and potential unit damage.
• Fan Operation: Verify that the condenser fan is operating smoothly and quietly. Any unusual noises or vibrations should be investigated.
• Refrigerant Leaks: Regularly check for any signs of refrigerant leaks around connections.
• Electrical Connections: Ensure all electrical connections remain secure and free from corrosion.

Refer to the specific maintenance schedule provided in the ice maker's instruction manual for integrated system maintenance.

7. Troubleshooting

If the remote condenser or the connected ice maker is not functioning correctly, perform the following basic checks before contacting service personnel. For complex issues, always consult a qualified refrigeration technician.

• No Power: Check the circuit breaker and ensure the unit is properly hardwired.
• Reduced Performance: Verify that the condenser coils are clean and free of obstructions. Ensure adequate airflow around the unit.
• Unusual Noises: Investigate the source of any abnormal sounds. This may indicate a fan issue or other mechanical problem.

Do not attempt to repair the unit yourself. Contact Hoshizaki Technical Support or a certified service provider.
