Owner's Manual for GREE 30,000-36,000 BTU Floor Ceiling Air Conditioner

Quick guide from the manual

This document provides essential information for the installation, operation, and maintenance of the GREE Floor Ceiling Type Air Conditioner (30,000-36,000 BTU). Key procedures include proper installation of the indoor unit, connection of refrigerant piping, vacuuming the system, and electrical wiring. Users should pay close attention to safety warnings regarding the use of R32 flammable refrigerant.

Safety Precautions

The unit uses R32 refrigerant, which is flammable. Installation, maintenance, and repair must be performed by qualified professionals. Ensure the installation room meets the minimum area requirements specified on the nameplate. Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacturer. Keep ventilation openings clear and avoid ignition sources in the maintenance area.

Unit Overview

The system consists of an indoor unit and an outdoor unit. Main components include the guide louver, air filter, and various connection pipes (gas and liquid). The unit can be controlled via a wired controller (optional) or a wireless remote controller.

Remote Controller Functions

The remote controller allows for various settings:

• Operation Modes: Auto, Cool, Dry, Fan, and Heat.
• Fan Speed: Adjustable from low to high, including Turbo and Quiet modes.
• Special Functions: X-FAN (dries the evaporator after shutdown), I FEEL (adjusts temperature based on remote sensor), Sleep mode, and 8°C heating function.
• Swing: Control of up/down and left/right air blowing angles.
• Child Lock: Prevents unauthorized changes to settings.

Installation

Installation must be carried out by authorized personnel in accordance with national wiring standards. Key steps include:

• Location Selection: Choose a location strong enough to support the unit's weight, away from heat sources, steam, or flammable gas.
• Pipe Connection: Use a pipe cutter to cut pipes, remove burrs, and flare the ends. Ensure pipes are not bent more than 90 degrees or repeatedly bent.
• Vacuuming: Use a vacuum pump to remove air from the system before opening the valves. Verify pressure gauge readings to ensure no leaks.
• Drain Pipe: Install with a downward slope of at least 1/100 to ensure smooth drainage.
• Electrical Wiring: Ensure the unit is properly grounded and connected to a dedicated branch circuit with a circuit breaker.

Troubleshooting

If the unit malfunctions, check the error codes displayed on the indoor unit or wired controller:

• E1: Compressor high pressure protection.
• E2: Indoor anti-freeze protection.
• E3: Compressor low pressure protection/refrigerant lack.
• E4: Compressor high discharge temperature protection.
• E5: AC over-current protection.
• E6: Communication error.
• EA: Refrigerant leakage alarm.
• EE: Loading EEPROM malfunction.

If the unit fails to start, check the power supply and leakage switch. For poor cooling or heating, check for dirty filters, open doors/windows, or refrigerant leaks.

Maintenance

Regular maintenance is required. Always disconnect the power supply before cleaning. Do not wash the unit with water. If the refrigerant sensor is damaged or reaches its service life, contact the after-sales service team for replacement.
