When selecting a location for your GREE FXE60HP230V1R32AO, follow these guidelines:

The unit must be installed where it is strong enough to withstand its weight and be fixed securely to prevent toppling or falling.

Install the air conditioner at a place where the inclination is less than 5°.

Do not install where there is a danger of combustible gas leakage.

Ensure noise and air flow produced by the outdoor unit will not disturb neighbors.

Select a location that is safe and away from animals and plants. If necessary, add safety fences to protect the unit.

Install in a place with good ventilation. Ensure the outdoor unit is in a well-ventilated place with no obstacles that may obstruct the air inlet and outlet.

The location should be able to withstand the weight and vibration of the outdoor unit and allow for safe installation.

Avoid installing at a place with leakage of inflammable gas, oil smoke, or corrosive gas.

Keep it away from strong wind, as this can affect the outdoor fan’s performance.

Install the outdoor unit at a place where condensate can be easily drained.

For areas with frequent snowfall, take the following precautions for your GREE FXE60HP230V1R32AO:

1) Install the air conditioner on a stand that is more than 20 in. (500mm) higher than the expected snowfall to prevent it from being covered by snow.

2) Attach a snow hood and snow guard.

3) Do not install the air conditioner at a place where a snowdrift is generated.

4) Remove the air inlet grille to prevent snow from accumulating on it.

5) Plugs and drainage connectors are not recommended.

The unit should be raised with support frames. If possible, avoid locations that are likely to accumulate snow. If not possible, a snow guard should be installed on the unit to prevent accumulation of snow on the top of the unit.

(1) Cut the connection pipe with a pipe cutter.

(2) The mouth of the connection pipe should face downward. Remove burrs from the cut surface so that chips do not enter the pipe.

(3) Remove the cut-off valve of the outdoor unit and take out the flare nut from the bag of indoor unit accessories. Then fit the flare nut on the pipe and use a flaring tool to flare the mouth of the connection pipe.

(4) Check whether the flaring part has cracked.

(5) If you replace the outdoor unit, you need to weld an additional dry filter at the gas pipe.

Before vacuum pumping, ensure the unit cut-off valves are closed.

(1) Remove the caps of the liquid valve, gas valve, and also the service port.

(2) Connect the hoses at the low pressure and high pressure sides of the manifold valve assembly to the service ports of the unit’s gas valve and liquid valve. The gas and liquid valves should be kept closed to prevent refrigerant leak.

(3) Connect the hose used for evacuation to the vacuum pump.

(4) Open the switch at the lower pressure side of the manifold valve assembly and start the vacuum pump. The switch at the high pressure side of the manifold valve assembly should be kept closed.

(5) The evacuation duration for the GREE FXE60HP230V1R32AO is generally 45 minutes. Verify if the pressure gauge at the low pressure side of the manifold valve assembly reads -0.1MPa. If not, there is a leak. Close the switch fully and then stop the vacuum pump.

(6) Wait for 10 minutes to see if the system pressure can remain unchanged. The pressure gauge reading should not be larger than 0.005MPa.

(7) Slightly open the liquid valve and let some refrigerant go to the connection pipe to balance the pressure inside and outside, preventing air from entering when removing the hose.

(8) Place back the caps of the liquid valve, gas valve, and also the service port. Note that the gas and liquid valves can be opened fully only after the manifold valve assembly is removed.

NOTE: All wires must go through the tube.

The terminal letters for the GREE FXE60HP230V1R32AO are defined as follows:

Y: Compressor control signal.

B: 4-way valve control signal (energized under the heating mode).

D: Defrosting signal.

R: 24V AC power supply.

C: 24V common.

L: Refrigerant leakage protection signal.

NOTE: RS485 mode wiring is not connected to Y, B, D, L. 24V mode wiring requires all connections. When the outdoor unit defrosts, terminal D will send a 24V signal to avoid cold winds. As for indoor units which do not include D, there is no need to connect the D terminals. L must be connected to the indoor machine.

Preparation before connecting the power:

(1) Power must not be connected if the installation work is not completed.

(2) Control circuit is correct and all the wires are firmly connected.

(3) Cut-off valves of the gas pipe and liquid pipe are open.

(4) The inside of the unit and the duct of the indoor unit should be clean. Take irrelevant objects out if there is any.

(5) After checking, re-install the front side plate.

Operation after connecting the power:

(1) If all the above works are finished, power on the unit. Otherwise, it is forbidden to power on the unit.

(2) If the outside temperature is more than 30°C, heating mode can’t be enabled.

(3) Before test operation, make sure the unit is powered on and the compressor has been preheated for more than 8 hours. Touch the unit to check whether it’s normally preheated. Start test operation after the unit is normally preheated, otherwise the compressor might be damaged. Debugging must be performed by professional technicians.

(4) Make sure the units can run normally.

(5) If there’s a sound of liquid shock when the compressor is running, then stop the air conditioner immediately. Wait until the electric heating belt is heated enough, and then restart the air conditioner.

If abnormal things (for example, awful smell) occur, please stop the unit immediately and disconnect power. Do not repair the air conditioner by yourself. If the LED displayer on the mainboard of the outdoor unit displays an error code, please refer to the following table:

Only professionals are allowed to carry on daily maintenance. Before cleaning, make sure the unit is stopped and the power is cut off.

Heat Exchanger of Outdoor Unit:

Clean the heat exchanger of the outdoor unit periodically, at least once every two months. Clean the dust and sundries on the surface of the heat exchanger with a dust collector and nylon brush. If there’s a compressed air source, use it to blow the dust off the surface of the heat exchanger. Do not use tap water for cleaning.

Drainage Pipe:

Periodically check if the drainage pipe is blocked to ensure smooth condensate water flow.

Notices at the Beginning of the Using Season:

(1) Check if the air inlet/outlet of the units are blocked.

(2) Check if the ground connection is reliable.

(3) Check if the air filter screen is properly installed.

(4) If starting up again after a long-term shutdown, set the power switch to “ON” for at least 8 hours before operation to preheat the crankcase of the outdoor compressor.

(5) Check if the installation of the outdoor unit is firm.

Maintenance at the End of the Using Season:

(1) Cut off the main power of the air conditioner.

(2) Clean the dust and sundries in the outdoor unit.

(3) If the outdoor unit is rusty, coat the rusty location with paint to prevent it from expanding.

Servicing a system with flammable refrigerants requires special procedures to ensure safety. The following must be adhered to:

Checks to the Area: Prior to beginning work, safety checks are necessary to ensure the risk of ignition is minimized. The area shall be checked with an appropriate refrigerant detector before and during work.

When removing refrigerant from the GREE FXE60HP230V1R32AO for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely.

Removal and Evacuation:

For flammable refrigerants, it is important that best practice be followed. The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be purged with oxygen-free nitrogen to render the appliance safe. This process might need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant systems.

Decommissioning:

Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details.

(1) Become familiar with the equipment and its operation.

(2) Isolate the system electrically.

(3) Ensure mechanical handling equipment is available, all personal protective equipment is available and being used correctly, and the recovery process is supervised by a competent person.

(4) Pump down the refrigerant system, if possible.

(5) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.

(6) Make sure the cylinder is situated on the scales before recovery takes place.

(7) Start the recovery machine and operate in accordance with the manufacturer’s instructions.

(8) Do not overfill cylinders (no more than 80% volume liquid charge).

(9) Do not exceed the maximum working pressure of the cylinder, even temporarily.

(10) When cylinders have been filled correctly, remove them from the site promptly and close all isolation valves on the equipment.

Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.
