This document serves as an operating manual for the CAPRI series of refrigerated wall-sited undermount cabinets, specifically the 0.7 SK slide and 1.12 SK slide models. These cabinets are designed for the demonstration, short-term storage, and sale of pre-cooled (or frozen) food products in trade and public catering enterprises. The device consists of a case and a refrigerating unit located in the lower part of the cabinet.
Function Description
The primary function of the CAPRI refrigeration cabinet is to maintain a set temperature range for storing products. It is equipped with an undermount refrigerating unit and is designed for medium temperature applications, with an effective volume temperature ranging from 0 to +7°C when the environment temperature is 25°C and relative humidity is 60%. The controller automatically maintains the set temperature level in the refrigerated enclosure and manages the evaporator defrosting process. A switch controls the internal lighting of the cabinet.

The device utilizes the inflammable refrigerant R-290. It is crucial to prevent any damage to the refrigeration circuit. The climatic categories for the device, according to GOST IEC 60335-2-89-2013, indicate its suitability for various environmental conditions, with humidity levels up to 80% and temperatures up to 40°C. Condensation on the external surface due to high humidity is not considered a malfunction.
Usage Features
- Installation: Installation, commissioning, technical maintenance, and repairs must be performed by specialist technicians from a specialized organization (service provider) in strict compliance with labor safety standards. No alterations to the product design are permitted.
- Placement: The device should be placed on a wooden pallet for movement with a forklift. A minimum 100mm gap must be maintained between the device's back wall and any adjacent wall. It should not be installed closer than 2 meters from heating units, under direct sunlight, or in areas with strong air drafts (exceeding 0.2m/s) or humidity levels outside the specified limits.
- Leveling: The device must be placed in a stable horizontal position, angled 3° away from the customer. This ensures zero-noise performance, correct condensate accumulation, and eliminates potential skewness or gaps between doors.
- Initial Power-Up: If the device has been tilted by more than 15°, it should not be powered on for a full day to prevent oil from the compressor crankcase spilling into the suction intake, which could lead to device failure. If stored or transported in temperatures below 12°C, it must be kept at a temperature above +12°C for at least 12 hours before connecting to the power grid to prevent compressor jam.
- Loading: Before loading, power up the device and wait for the internal temperature to reach the set parameter. Load pre-cooled (or frozen) products evenly, leaving no empty spaces, and avoid overloading shelves.
- Air Circulation: Maintain at least a 10mm gap between products, and between products and side walls. The gap between products and the back wall should be at least 25mm. Loading height should be 25mm less than the distance between adjacent rack-shelves. A minimum 50mm gap is required between products and air outlets. Do not obstruct air paths with paper, plastic film, or other air-proof materials. Failure to follow these rules can impair air circulation and device performance, potentially spoiling food.
- Safety: Do not store explosive items or aerosol sprays with inflammable liquids. Avoid stepping on the device to prevent deformation, overturning, or injuries.
- Power Connection: Connect the device to the power grid via an automatic electromagnetic protection shutoff and a differential switch (GFI). The automatic shutoff should have the nearest trip setting value, and the differential trigger amperage should be higher than the automatic trigger, with a nominal shutting differential amperage of 30mA. The device has a power cord with a grounding contact. Do not use the device without proper grounding, automatic shutoff, circuit breaker, or with faulty/removed control equipment, insufficient wiring insulation, or damaged parts. Do not use an extension cord. After turning off the power, wait 5 minutes before powering the device on again.
- Controller: The controller's settings are optimized by the manufacturer. Any changes must be made by qualified technical personnel according to the controller manual.
- Door Usage: Frequent door opening can increase internal temperature. For two-door models, open only one door at a time when loading to minimize temperature fluctuations.
- Personnel: Only enterprise employees who are medically examined, instructed on safety measures, and skilled in operating the device according to this manual should operate it.
Maintenance Features
- Regular Cleaning: Clean (wash) the inner and outer surfaces and removable parts with a neutral detergent and warm water, then dry with a soft cloth. This should be done at least once every two weeks for inner surfaces and removable parts (leaving slide-doors open to dry), and at least once a week for outer surfaces. Always disconnect the device from the power grid before cleaning.
- Monitoring: Regularly observe the temperature in the refrigerated enclosure, inspect the device's condition, correct loading, and the melt-water draining system.
- Abnormal Performance: If abnormal performance is noticed or the inside temperature rises above acceptable limits, disconnect the device from the power source, remove stored items to prevent spoilage, and call a technical specialist.
- Monthly Maintenance (by Service Provider): To ensure stable and reliable performance, a service provider must conduct monthly maintenance, which includes:
- Visual inspection of the device's technical condition and completeness.
- Checking grounding, its components, connections, and contact resistance (should not exceed 0.1 Ohm).
- Checking lighting.
- Checking automatic defrosting system performance in the evaporator and condensate draining system.
- Cleaning the condenser from dust and dirt.
- Checking the integrity of the refrigeration system.
- Ensuring the leak current is below 3.5mA.
- Disconnect the device from the power grid for procedures a, b, e, f, and g.
- Warranty: The warranty period is 12 months from the date of sale, but not longer than 18 months from the manufacturing day. Warranty is valid during maintenance, but maintenance itself is a paid service. Warranty liabilities are nullified if the device operation violates manual requirements, sustains damage from improper handling/transportation/storage, incorrect connection/setup, abnormal operation, voltage fluctuations, natural calamities, altered design, unauthorized repairs, mechanical damage, chemical exposure, or operation in conditions not specified in Article 1.3. Plastic/rubber parts, sealants, gaskets, price tag holders, light sources, and expendable materials are not covered by warranty.
- Disposal: After the service life expires, the device should be disposed of according to local environmental law. Before moving to a waste disposal site, fully drain the refrigerant and oil. Burning the thermal insulation (polyurethane foam) is prohibited; such materials must be buried in a special waste site at least 2 meters deep. Do not release refrigerant into the environment or dump oil into the ground, water, or holding ponds.
