Installation Warnings and Guidelines
Air Flow Requirements
⚠️ DANGER: Insufficient air flow results in shortened lifespan and reduced cooling performance.
Observe the minimum spacings when installing the refrigerator to furniture or surrounding structures to ensure adequate ventilation.
- A (Front Airflow): Maintain a minimum clearance of 50 mm (2 in) in front of the unit.
- B (Rear Airflow): Maintain a minimum clearance of 50 mm (2 in) behind the unit.
- Ensure unobstructed air circulation around the refrigerator.
Diagrams show required clearances for proper ventilation.
General Installation Notices
- Electrical Safety: Ensure the unit is connected to a suitable power source. For AC operation, a 100-240V connection is required. For DC operation, use 12V or 24V systems. A Residual Current Device (RCD) is recommended for safety.
- Environmental Conditions: Avoid installing the refrigerator in direct sunlight or areas exposed to excessive moisture.
- Positioning: Do not expose the unit to water spray. Ensure the unit is not tilted beyond 30 degrees.
- Refrigerant: The unit uses R134a refrigerant.
Condensation Drain
Proper drainage of condensation is essential. Follow these steps:
- Connect the condensation drain tube to the designated outlet on the refrigerator.
- Route the drain tube to a suitable collection point or overboard, ensuring it is not kinked.
- Periodically check and clean the drain tube to prevent blockages.
Installation Procedures
Electrical Connections
The refrigerator can operate on DC (12V/24V) or AC (100-240V) power.
DC Power (12V / 24V)
Select the appropriate wire gauge based on the cable length to ensure efficient power delivery and prevent voltage drop.
| 12V System | 24V System | ||
|---|---|---|---|
| Cable Length (l/m) | Wire Cross-Section (Ø/mm²) | Cable Length (l/m) | Wire Cross-Section (Ø/mm²) |
| 0 - 2 | 2.5 | 0 - 4 | 1.5 |
| 2 - 4 | 4 | 4 - 8 | 2.5 |
| 4 - 6 | 6 | 8 - 12 | 4 |
| 6 - 8 | 8 | 12 - 14 | 6 |
| - | - | 14 - 18 | 10 |
Example: For a 12V system with a cable length of 5 meters, use a wire cross-section of at least 6 mm².
Example: For a 24V system with a cable length of 10 meters, use a wire cross-section of at least 4 mm².
Ensure correct polarity (+/-) when connecting to the DC power source. A 15A fuse is recommended for both 12V and 24V systems.
AC Power (100-240V)
Connect the refrigerator to a standard AC power outlet within the specified voltage range (100-240V) for the relevant region (America/Asia/Pacific).
Frame Installation
Mount the provided frame securely into the intended installation space. Ensure the frame is level and stable.
Diagrams show the frame being assembled and positioned.
Fixing the Refrigerator
Once the frame is installed, position the refrigerator within the frame. Secure the unit using the provided mounting hardware (screws) through the designated points.
Diagrams illustrate securing the unit with screws.
Sliding Hinge Installation
For refrigerators equipped with a sliding hinge mechanism:
- Attach the sliding rail components to the cabinet and the refrigerator door/body as indicated in the diagrams.
- Ensure correct alignment and clearance (typically 1-2 mm for the gap between door and cabinet, and 6-8 mm for the hinge mechanism itself).
- Slide the refrigerator into its final position, engaging the hinge mechanism.
- The maximum depth for the sliding mechanism is typically 40 mm (1.6 in).
Diagrams show the attachment of sliding rails and the unit being inserted.
Door Reversal (Hinge Side)
The refrigerator door can be mounted to open from the left or right. Follow these steps to reverse the door:
- Carefully remove the door from its current hinges.
- Disassemble the hinges and locking mechanisms from the original side.
- Reassemble the hinges and locking mechanisms on the opposite side of the refrigerator body.
- Attach the door to the new hinge points.
- Adjust the door alignment and ensure it closes properly. The door can typically be opened up to 180 degrees.
Diagrams illustrate the process of removing, transferring, and reattaching the door and hinges.
