Error Codes

The following table lists common error codes and their descriptions:

Normal Operation Codes

Maintenance & Service

Air Filter

It is important to check and clean the air filter as per the maintenance Schedule. A dirty air filter will not allow the correct amount of clean air to pass through your air conditioner, resulting in poor performance and increased running costs. You should ask the installer to show you where the air filter is located.

To clean the air filter, it should be removed and then cleaned with a vacuum cleaner. If it is very dirty, wash it with soapy water and then wipe off. Make sure it is completely dry before refitting it. You should never operate the air conditioner without the air filter in place.

Indoor Coil

It is advisable to have the drain connections checked on an annual basis (as set out in the Maintenance Schedule). Drains can be blocked by all types of insects, and rats have been known to chew through the drain to get to the water in the pipe.

Outdoor Unit

The Outdoor unit has either one or two fans; it draws air through the appliance to expel the heat generated during the cooling cycle. It is recommended to check that plants haven't grown into or around the air intake or outlet, along with other debris that may build up over time, namely, leaves and the like.

Refrigerant

The refrigerant is the lifeblood of your air conditioning unit. Not only does the correct refrigerant charge provide reliable and economical cooling, it also provides the air conditioning for the compressor. A lack of refrigerant, due to a leak, will cause the compressor to overheat and expire prematurely. You will notice a decline in air conditioning effect and an increase in power consumption. Therefore, having a qualified, licensed technician service your appliance will save you money in the long term.

Maintenance Schedule

Items to be done by the Home Owner/User:

• Air filter cleaning (Monthly, Annually)
• Air filter replacement (Annually)
• Maintain required clearance around Outdoor unit (Annually)

Items to be done by a Qualified Licensed Technician:

• Check, clean or replace filter (Annually)
• Check drain from indoor coil (Annually)
• Check Outdoor unit clearances – maintain garden and debris (Annually)
• Check refrigerant charge (Annually)
• Check refrigeration connections for soundness (Annually)
• Check outdoor fans (Annually)
• Check electrical connections (Annually)
• Check overall installation (Annually)
• Report to the home owner/user all tasks that require attention (Annually)

The Maintenance Schedule covers Year 1 to Year 6. It is strongly recommended to continue to maintain and service the Gree Ducted Inverter Air Conditioning appliance as per the items and frequency set out in the Schedule.

Operation Tips

The following events may occur during normal operation:

• 1. Protection of the air conditioner: The compressor cannot restart for 3 minutes after it stops.
• 2. A white mist coming out from the Indoor unit: A white mist may generate due to a large temperature difference between air inlet and air outlet on COOL mode in an indoor environment that has a high relative humidity.
• 3. Low noise of the air conditioner: You may hear a low hissing or gurgling sound when the compressor is running or has just stopped running. This is the sound of the refrigerant flowing or coming to a stop. You can also hear a low "squeak” sound when the compressor is running or has just stopped running. This is caused by heat expansion and cold contraction of the plastic parts in the appliance when the temperature is changing.
• 4. Dust is blown out from the Indoor unit: This is a normal condition when the air conditioner has not been used for a long time or during first use of the appliance.
• 5. A peculiar smell comes out from the Indoor unit: This is caused by the Indoor unit giving off smells permeated from building material, from furniture, smoke (for example if someone is cooking food, candles, incense), or from the duct work.
• 6. FAN operation during COOL mode: When indoor air temperature reaches the setting on the wired wall control, the compressor will stop operating and after approximately 60 seconds the indoor fan will stop blowing air. Unless X-Fan has been activated where the indoor fan will continue for some minutes to dry the coil of the indoor unit. When the room temperature rises back to the set point, the indoor fan and the compressor will start again.

Clearances

Diagrams and tables indicate required clearances for the outdoor unit. Note: Distance in front of the outdoor may be reduced with the use of the Gree air deflection grilles. Consult your installer for more information.

Filter Cleaning Reminder

This chart provides accumulated operating time based on pollution level for filter cleaning reminders.

DRED

For national power shortage, this function responds to DRED signal within 1 second. Where DRED function is connected, the power supply authority may limit the amount of power being consumed by switching the DRED signal on the appliance.

I-DEMAND

Satisfies basic cooling requirements while saving power up to 25%. After setting, the fan speed is fixed at AUTO. This function limits power usage to 75%, which may make cooling or heating take longer, but reduces power consumption. Under I-Demand, the set point is fixed at 27°C and the indoor fan is fixed at AUTO.
