  • Page 9 Normal Phenomenon that Are Not Air Conditioner Faults The following phenomena are normal during operation of the air conditioner. They can be solved according to the instructions below or do not need to be solved. The IDU emits white mist 1.
  • Page 10: Display Panel Description

    In winter, the outdoor temperature is low, and the heating effect may be decreased 1. During the heating operation of the cooling and heating type air conditioner, the air conditioner absorbs heat from the outdoor air and releases it to heat the indoor air. This is the heat pump heating principle of the air conditioner.
  • Page 11: Installation

    If installed improperly, fire, electric shock, injury, or water leakage may occur. For optional accessories and accessories that are sold separately, use only the products specified by Midea. The installation of these accessories must be carried out by professionals. Improper installation may cause fire, electric shock, water leakage and other hazards.
  • Page 12 Before and after installation, exposing the unit to water or moisture will cause electric part short-circuit. Do not store the unit in a humid basement or expose it to rain or water. Make sure the installation base and lifting are robust and reliable; Insecure installation of the base may cause the air conditioner to drop leading to accidents.
  • Page 13 Forbidden Installation Sites [ Warning ] Do not install or use the air conditioner in the following places: A place filled with mineral oil, fumes or mist, like a kitchen. Plastic parts will age and the heat exchanger will be dirty, eventually causing the air conditioner to fall or leak water.

    Install the panel. Drain side Bolts and washers Make sure the two hooks are well secured. Panel hook (two) Tighten the screws under the panel hooks until the thickness of the sealing sponges 1 and 2 between the IDU and the panel outlet is reduced to about 4-6mm.
  • Page 28 [ Caution ] Improper screw tightening may cause the failure shown in the figure below. After tightening the screws, if there is still a gap between the ceiling and the panel, the height of the IDU must be readjusted. If the lift level of the IDU and the drainage pipes are not affected, you can remove the panel and readjust the height of the IDU.
  • Page 29: Refrigerant Connecting Piping Installation

    Refrigerant Connecting Piping Installation Length and level difference requirements for the pipe connections of IDU and ODU When connecting different ODUs, the length and level difference requirements for the pipe connections are different. For details, please follow the installation instructions of the ODU. [ Warning ] During installation of the connecting pipes, do not allow air, dust, and other debris to penetrate the piping system, and make sure the interior of the pipes is dry.
  • Page 30: Pipe Connection

    Steps of pipe connection Connect the IDU first, then connect the ODU. Before tightening the flare nut, apply refrigeration oil on the outer surface of the pipe flare and the conical surface of the connection nut (you must use refrigeration oil compatible with the refrigerant for this model), and tighten it by hand for 3 to 4 turns.
  • Page 31 Nitrogen Displacement Before welding the refrigerant connecting piping, carry out nitrogen replacement first, or fill the refrigerant piping with nitrogen during welding, and finally connect it to the IDU using the pipe socket. [ Warning ] When it is necessary to fill the piping with nitrogen during welding, the pressure must be controlled to 0.02MPa with a pressure relief valve.
  • Page 32: Air Discharge

    Pipe size (mm) Tightening torque [ N.m (kgf.cm)] [ Note ] According to the installation conditions, excessive torque will damage the pipe socket, and too small torque may cause air leakage due to loose screw tightening. Refer to the table above to determine the tightening torque. Refrigerant piping fixing Angle iron brackets or round steel hangers should be used for fixing.
  • Page 33: Drainage Pipe Installation

    Drainage Pipe Installation [ Caution ] Before installation of the condensate pipeline, determine its direction and elevation to avoid intersection with other pipelines to ensure that the slope is smooth and straight. The highest point of the drainage pipe should be provided with a discharge port to ensure the smooth discharge of condensate water, and the discharge port must face downwards to prevent dirt from entering the pipe.
  • Page 34 The connection between the two ends of the drainage pipes and the connection of the water pump outlet only need to be fastened with a cable tie, together with PVC/rubber adhesives. Pay attention to the instructions for use of the adhesives to prevent continuous corrosion to the EPDM rubber. Use hard PVC adhesives for connecting to other water piping.
  • Page 35 The end of the drainage pipe must be more than 50mm above the ground or from the base of the water discharge slot. In addition, do not submerge it in water. To discharge the condensed water directly into a ditch, the water discharge pipe must bend upwards to form a U-shaped water plug to stop the odour from entering the room via the water discharge pipe.
  • Page 36 Water Discharge Test Before the test, make sure that the water discharge pipeline is smooth, and check that each connection is sealed properly. Conduct the water discharge test in a new room before the ceiling is paved. The drainage pipe can be made of PVC pipe (outer diameter: 25mm). Based on the actual installation circumstance, users can purchase pipes with appropriate length from a sales agent or the local after-sales service center, or purchase directly from the market.
