This document is an Owner's Manual & Installation Manual for a One-way Cassette air conditioning unit from BLUERIDGE. It provides comprehensive information for both installation and operation, emphasizing safety precautions, technical specifications, usage features, and maintenance guidelines.
Function Description
The BLUERIDGE One-way Cassette is an air conditioning unit designed for indoor climate control. It operates in various modes including COOL, HEAT, and DRY, adapting to different environmental conditions. The unit features an electronic control box, air intake grille with an air filter, air vane, and a display panel for user interaction. It is designed to provide efficient cooling and heating, with specific considerations for energy saving and user comfort. The unit also includes a refrigerant leak detection system (for most models) and a three-minute protection feature to prevent immediate restarts after a power interruption, safeguarding the compressor.
Important Technical Specifications
The manual details operating temperature ranges for both indoor and outdoor units, crucial for optimal performance and to prevent safety features from activating.
- Room Temperature (COOL mode): 16°C-32°C (61°F - 90°F)
- Room Temperature (HEAT mode): 0°C -30°C (32°F - 86°F)
- Room Temperature (DRY mode): 10°C-32°C (50°F - 90°F)
- Outdoor Temperature (COOL mode): -25°C -50°C (-13°F - 122°F)
- Outdoor Temperature (HEAT mode): -25°C - 24°C (-13°F - 75°F)
- Outdoor Temperature (DRY mode): 0°C -50°C (32°F - 122°F)
- Fuse Specifications: T5A/250VAC and T10A/250VAC (printed on the circuit board).
- Pipe Lengths and Drop Heights: Detailed tables are provided for maximum refrigerant pipe lengths and drop heights based on capacity (Btu/h) and type (Inverter Split Type, Other Split Type). For example, a <15K BTU/h unit has a maximum piping length of 25m/82ft and a maximum drop height of 10m/32.8ft.
- Liquid Side Diameter: Φ6.35 (1/4 in), Φ9.52 (3/8 in), Φ12.7 (1/2 in).
- Refrigerant Type: R410A, with specific instructions for additional charging based on pipe length.
- Wall Hole Diameter for Drainpipe: 65mm (2.5in) or 90mm (3.54in) depending on models.
- Minimum Cross-Sectional Area of Power and Signal Cables: Ranging from 0.75 mm² for >3 and ≤6A to 6 mm² for >32 and ≤40A.
- Grounding Resistance: Must be less than 0.1Ω.
Usage Features
The unit incorporates several features to enhance user experience and energy efficiency:
- Display Panel: Shows temperature, operation features, and error codes. Indicators for electric heating, TIMER, unit on, alarm, wireless control, pre-heating/defrost, 8°C heating, Active Clean, WiFi AP mode, and forced cooling.
- Default Setting (Auto-Restart): After a power failure, the unit restarts with factory settings (AUTO mode, AUTO fan, 24°C/76°F) or previous settings if auto-restart is enabled.
- Sleep Operation: Reduces energy consumption during sleep by automatically adjusting the temperature (increasing by 1°C/2°F per hour for the first two hours in COOL mode, decreasing by 1°C/2°F per hour for the first two hours in HEAT mode). This function stops after 8 hours.
- Louver Angle Memory Function: Retains the previous horizontal louver position after a power failure.
- Active Clean Function: Automatically freezes and thaws frost on the heat exchanger to wash away dust, followed by hot air drying to keep the interior clean. The display shows "CL" during this 20-130 minute process.
- Lifting Panel Operation: Allows control of the grille's rise and fall via remote control for maintenance or access. The panel can reach a maximum height of 1.5 meters and has safety features to stop movement if blocked.
- Breeze Away: Prevents direct airflow on the body for a more comfortable experience.
- Energy Saving Tips: Recommendations include keeping doors/windows closed, using TIMER ON/OFF, not blocking air inlets/outlets, regular air filter cleaning, and proper louver adjustment.
Maintenance Features
The manual provides detailed instructions for cleaning and maintenance to ensure longevity and efficient operation:
- Safety Precautions: Emphasizes disconnecting power before any cleaning or maintenance, avoiding contact with internal components, and not using flammable sprays or excessive water.
- Air Filter Cleaning: Recommended every two weeks or more frequently in dusty areas. Instructions for removing the air filter (Model A and Model B) and cleaning it with a vacuum cleaner or water. For excessive dust, a soft brush and natural detergent can be used. Filters should not be dried under direct sunlight or with fire.
- Long Periods of Non-Use: Instructions to clean filters, run the FAN function to dry the unit, and then turn off and disconnect power.
- Pre-Season Inspection: Before frequent use, check for damaged wires, clean filters, and check for leaks.
- Troubleshooting Guide: A comprehensive table of common issues, possible causes, and solutions, including scenarios like the unit not turning on, mode changes, white mist emission, and various noises. It also addresses poor cooling performance.
- Water Discharge Test: Instructions to ensure the drainpipe is smooth and sealed, and to check for proper drainage during operation to prevent water level errors and overflow. Includes steps to manually drain accumulated water if necessary.
The manual also includes warnings regarding electrical work, fuse specifications, product installation, and refrigerant handling, stressing the importance of professional installation and adherence to local and national regulations.
