(8) The air conditioner can be cleaned only after it is turned off and power-disconnected.

(9) Do not alter the setting of the pressure sensor or other protective devices. If protective devices are short-circuited or changed against rules, fire hazard or explosion may occur.

(10) When installing or re-installing the air conditioner, keep the refrigerant circuit away from substances other than the specified refrigerant, such as air.

(11) The heat pump and the furnace cannot turn on the heating function at the same time, otherwise it will cause a safety failure.

(1) If a thermostat is to be used, it should be connected first before powering up the unit, otherwise the thermostat may not be able to use.

(2) Only use a soft dry cloth or slightly wet cloth with neutral detergent to clean the casing of the air conditioner.

(3) Before operating the unit under low temperature, connect it to power for 8 hours. If it is stopped for a short time (e.g., one night), do not cut off the power. This is to protect the compressor.

(4) To ensure reliability, the unit forces the compressor to run for at least 6 minutes every time it turns on. Therefore, it is necessary to select a thermostat with a minimum run time or a delay feature to avoid malfunction.

(5) To avoid unit abnormality caused by high pipe temperature, it is forbidden to use gas auxiliary when the outdoor unit is turned on.

(6) When welding the connecting pipe, the body of the cut-off valve should be wrapped with a wet cloth for protection to prevent damage to the O-ring seal.

(7) This product cannot be used in combination with other products, as it may cause performance, reliability, and safety problems.

The dimensions are provided in inches (mm).

The following table specifies the minimum installation clearances in inches.

For areas with frequent snowfall, please take the following precautions:

1) The outdoor unit does not have a TXV (thermal expansion valve). Ensure there is a throttling valve in the indoor unit (air handler or A coil).

2) Clean up snow in time to avoid covering the unit. It is suggested to raise the unit with support frames.

3) If possible, avoid locations that are likely to accumulate snow. If not, a snow guard should be installed on the unit to prevent snow accumulation on top.

4) 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.

5) Attach a snow hood and snow guard.

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

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

8) Plugs and drainage connectors are not recommended in snowy areas.

Connection pipe should adopt water-proof insulating material. Its wall thickness should be 0.5-1.0mm and the pipe wall should be able to withstand 6.0MPa. The longer the connection pipe, the worse the cooling and heating performance.

(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’s cut-off valves are closed and the outlet of the vacuum pump is away from fire sources and well-ventilated.

(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.

(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 should be kept closed.

(5) The evacuation duration is generally 45 minutes for the FXE36HP230V1R32AO. Verify that the pressure gauge at the low pressure side of the manifold valve assembly reads -0.1MPa. If not, there is a leak.

(6) After evacuation, close the switch fully and stop the vacuum pump. Wait for 10 minutes to see if the system pressure remains unchanged. The reading on the low-pressure gauge should not be larger than 0.005MPa.

(7) Slightly open the liquid valve to let some refrigerant into the connection pipe to balance the pressure. This prevents air from entering when removing the hose. The gas and liquid valves can be opened fully only after the manifold valve assembly is removed.

(8) Place back the caps of the liquid valve, gas valve, and also the service port.

The standard pipe length for the GREE FXE36HP230V1R32AO is 7.5m. No additional refrigerant is needed if the pipe length is up to 9.5m. If the pipe length exceeds 9.5m, you need to add an additional 20g of refrigerant for each extra meter of pipe.

NOTE: Compliance with relevant national gas regulations: Indoor refrigerant joints made on site shall be tested for tightness. The test method shall be leak detection with equipment with a sensitivity of 5g/year or higher at a minimum of 0.25 times the maximum allowable pressure. There shall be no leakage detection.

NOTE: All wires must go through the tube.

NOTE: The meanings of the terminals are 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.

RS485 mode wiring is not connected to Y, B, D, L. 24V mode wiring requires all connections.

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. Remove any irrelevant objects.

(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 the 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, stop the air conditioner immediately. Wait until the electric heating belt is heated enough, and then restart the air conditioner.

If your air conditioner fails to function normally, please check the following items before requesting maintenance.
