This document is an owner's manual for a GREE Window Type Air Conditioner, model GJC08BK-A6NRNC5B. It provides comprehensive information on the unit's operation, maintenance, installation, and safety precautions.

Function Description

The GREE Window Type Air Conditioner is designed to provide cooling and dehumidification for indoor spaces. It features multiple operating modes including Auto, Cool, Energy Save, Fan Only, and Dry. The unit can be controlled via a control panel on the unit itself or through a remote controller.

Operating Modes:

Auto Mode: The unit operates automatically based on ex-factory settings, and the set temperature cannot be adjusted.
Cool Mode: The air conditioner operates in cooling mode. The cooling indicator will be on, and the fan speed can be adjusted.
Energy Save Mode (SE): The unit operates in energy-saving mode. The SE indicator will be on, and the fan speed can be adjusted.
Fan Only Mode: The unit only blows wind without cooling or heating. The fan indicator will be on, and the fan speed can be adjusted (no auto fan speed in this mode).
Dry Mode: The unit runs at a low fan speed for dehumidification. The corresponding indicator will be on, and the fan speed cannot be adjusted.

Timer Function: The unit features a timer function for both turning on (TIMER ON) and turning off (TIMER OFF).

TIMER ON: Can be set when the unit is off. The timer can be set in 0.5-hour increments below 10 hours and 1-hour increments for 10 hours or above, with a setting range of 0.5 to 24 hours.
TIMER OFF: Can be set when the unit is on. The timer can be set in 0.5-hour increments below 10 hours and 1-hour increments for 10 hours or above, with a setting range of 0.5 to 24 hours.

Fan Speed Adjustment: The fan speed can be selected from Auto, Low, Medium, or High settings. The remote controller offers four fan speeds (Speed 1, Speed 2, Speed 3, Speed 4), though the specific model GJC08BK-A6NRNC5B has three speeds.

Filter Check Function: After 250 hours of total fan operation, a lamp will illuminate to remind the user to clean the filter. Pressing the "Filter check" button clears the operation time and turns off the warning indicator.

Temperature Setting: The set temperature can be adjusted in 1°F (or 1°C) increments using the up/down buttons on the control panel or remote controller. The temperature setting range is 61~86°F (17~30°C).

I FEEL Function (Remote Controller): When activated, the unit will operate based on the ambient temperature value sent by the remote controller every 10 minutes. If no signal is received after 11 minutes, it reverts to using the AC's internal temperature sensor. This function is not memorized if power is lost.

SLEEP Function (Remote Controller): This mode adjusts the temperature to maintain comfort during sleep and is available in Cool, Save, Heat (for models with heating), or Dry modes.

Light Function (Remote Controller Combination Button): Holding the "up" and "down" buttons simultaneously for 3 seconds can toggle the lamp on or off. The lamp is defaulted to "on" when energized.

Child Lock Function (Remote Controller Combination Button): Pressing the "up" and "down" buttons simultaneously can activate or deactivate the child lock. When active, the LOCK indicator on the remote controller is ON, and the remote controller will not send signals.

Temperature Display Switch Over (Remote Controller Combination Button): While the unit is OFF, pressing the "down" button and the "up" button simultaneously can switch the temperature display between °C and °F.

Fan Direction Adjustment:
- Left & Right: An adjusting rod allows manual adjustment of the horizontal airflow direction.
- Up & Down: The air outlet frame can be manually adjusted to select the vertical airflow direction.
Power Failure Memory: If the unit is energized after a power failure, it will resume operation according to its status before the power failure.
Error Indication: In certain error conditions (e.g., remote controller signal issues), the buzzer will emit two sounds.
Malfunction Codes: The dual-8 nixie tube display will show specific malfunction codes (e.g., F1, F2, F4, FJ, EP, F0, H3) if an abnormal phenomenon occurs, indicating the need for professional service. EP code is for cooling-only units, while F1/F2/F4/FJ are for electric heating models.

Maintenance Features

Filter Cleaning:

Open the front panel by pulling the grooves on both sides.
Remove the filter.
Clean the filter using a dust catcher or water. For very dirty filters, use warm water with a neutral detergent and dry in a shady place.
Reinstall the filter and close the panel.

Frequency: Clean the filter approximately every three months, or more frequently in dusty environments.
Caution: Avoid touching metal fins, do not dry the filter with fire or a hair dryer, and do not operate the unit without the filter installed.

Panel Cleaning: Wipe the panel surface with a soft dry cloth or a wet cloth dipped in neutral detergent. Do not remove the panel for cleaning.

Outer Case Maintenance: Check the outer case once or twice a year for damage or rust. Contact the dealer if issues are found. A protective covering is recommended during off-season to prevent damage or rust.

Safety Precautions:

Always turn off the air conditioner and disconnect power before cleaning or maintenance to prevent electric shock.
Do not wash the unit with water.
Do not use volatile liquids (e.g., wax, thinner) for cleaning.

Power Cord Check: Periodically check the power cord's creepage protection device by pressing the "TEST" button (indicator turns OFF, sound heard) and then the "RESET" button (indicator turns ON). If the device fails to reset or trips frequently, the power supply cord must be replaced by the manufacturer.

General Troubleshooting: The manual provides a troubleshooting chart for common issues like the unit not operating, poor cooling, fan not blowing, temperature not adjustable, odors, abnormal sounds, and remote controller insensitivity, along with suggested solutions.
