GREE Multi Variable Air Conditioners Indoor Unit INSTALLATION 43
GREE Multi Variable Air Conditioners Indoor Unit 1 Engineering Installation Preparation and Notice 1.1 Installation Notice All phases of this installation must conform to NATIONAL, STATE AND LOCAL CODES. If it is required for additional information, please contact your local distributor. Personnel and property safety are highly concerned during the entire installation process. Installation implementation must abide by relevant national safety regulations to ensure personnel and property safety. All personnel involved in the installation must attend safety education courses and pass corresponding safety examinations before installation. Only qualified personnel can attend the installation. Relevant personnel must be held responsible for any violation of the regulation. 1.2 Installation Key Points and Importance VRF air conditioning systems use refrigerant, instead of other agent, to directly evaporate to carry out the system heat. High level of pipe cleanness and dryness is required in the system. Since various pipes need to be prepared and laid out onsite, carelessness or maloperation during installation may leave impurities, water, or dust inside refrigerant pipes. If the design fails to meet the requirement, various problems may occur in the system or even lead to system breakdown. Problems that usually occur during installation are as follows: No. Installation Problem Possible Consequence 1 Dust or impurities enter into the refrigeration system. Nitrogen is not filled into the refrigerant pipe or insufficient Nitrogen is filled before welding. 2 3 The vacuum degree in the refrigerant pipe is insufficient. 4 Water enters into the refrigeration system. The refrigerant pipe specifications do not meet the configuration requirements. 5 6 Refrigerant pipe is blocked. 7 Refrigerant pipe exceeds the limit. 8 Incorrect amount of refrigerant is filled. 9 The refrigerant pipe leaks. CHAPTER 3 INSTALLATION Pipes are more likely to be blocked; air conditioning performance is reduced; compressor wear is increased or even hinder the normal operation of the system and burn the compressor. Pipes are more likely to be blocked; air conditioning performance is reduced; compressor wear is increased or even hinder the normal operation of the system and burn the compressor. The refrigeration performance is reduced. The system fails to keep normal operation due to frequent protection measures. When the problem getting serious, compressor and other major components can be damaged. Copper plating may appear on the compressor and reduce the compressor efficiency with abnormal noise generated; failures may occur in the system due to ice plug. Smaller configuration specifications can increase the system pipe resistance and affect the cooling performance; larger configuration specifications are waste of materials and can also reduce the cooling performance. The cooling performance is reduced; in certain cases, it may cause long-term compressor operating under overheat conditions; the lubricating effect can be affected and the compressor may be burnt if impurities were mixed with the lubricating oil. The loss in pipe is considerable and the unit energy efficiency decreases, which are harmful for long-term running of the system. The system cannot correctly control the flow allocation; the compressor may be operating under over-heating environment or running when the refrigerant flows back to the compressor. Insufficient refrigerant circulating in the system decreases the cooling performance of the air conditioner. Long-term operation under such circumstance may cause an overheating compressor or even damage the compressor. 44
GREE Multi Variable Air Conditioners Indoor Unit No. Installation Problem Possible Consequence 10 Water drainage from the condensate water pipe is not smooth. The ratio of slop for condensate water pipe is insufficient or the condensate water pipe is incorrectly connected. 11 12 The air channel is improperly fixed. The air channel will deform; vibration and noise occur during unit operating. 13 The guide vane of air channel is not reasonably manufactured. The refrigerant pipe or condensate water pipe does not meet the insulation requirement. 14 15 The installation space for IDU is insufficient. The IDU or the location of the air outlet or return air inlet is not designed reasonably. 16 17 The ODU is improperly installed. 18 Power cables are incorrectly provided. Unit components may be damaged and potential safety hazard may occur. Control communication cables are incorrectly provided or improperly connected. 19 20 Control communication cables are not properly protected. Understand the special requirement (if any) for unit installation before implementation to ensure installation quality. Relevant installers must have corresponding engineering construction qualifications. Special type operators involved in the engineering implementation, such as welders, electricians, and refrigeration mechanics must have relevant operating licenses and are accredited with vocational qualification certification. 2 Installation Materials Selection The materials, equipment and instruments used during air conditioning engineering construction must have certifications and test reports. Products with fireproof requirements must be provided with fireproof inspection certificates and must meet national and relevant compulsory standards. If environmentally-friendly materials are to be used as required by customers, all such materials must meet national environmental protection requirement and be provided with relevant certificates. (1) Only auxiliary devices approved by the appliance manufacturer or declared suitable with the refrigerant shall be installed in connecting ductwork; (2) Do NOT install operating ignition sources (example: open flames, an operating gas appliance or Residual water in IDUs can affect the normal operation of the system. The possible water leakage can damage the IDU's decoration. Reverse slop or inconsistent connection of condensate water pipe can hinder the smooth drainage and cause leakage of the IDU. Uneven air quantity allocation reduces the overall performance of the air conditioner. Water can easily condensate and drip to damage the indoor decoration, or even trigger the protection mode of system due to overheating operation. Since there is a lack of space for maintenance and checking, indoor decoration might need to be damaged during such operation. The air outlet or return air inlet may be short-circuited, thus affecting the air conditioning performance. The ODU is difficult to be maintained; unit exhaust is not smooth, which reduces the heat exchanging performance or even prevent the system from normal operation; in addition, the cold and hot air for heat exchange and the noise may annoy people in surrounding areas. The normal communication in the system fails or the control over IDUs and ODUs turn in a mess. The communication cables are short-circuited or disconnected, and the unit cannot be started up due to communication failure. 45

GREE Multi Variable Air Conditioners Indoor Unit 4 Installation of Connection Pipe ① Conform to the following principles during pipe connection: Connection pipe should be as short as possible, so is the height difference between indoor and outdoor units. Keep the number of bends as little as possible. Radius of curvature should be as large as possible. ② Weld the connection pipe between indoor and outdoor units. Please strictly follow the requirements for welding process. Rosin joint or pin hole is not allowed. ③ When laying the pipe, be careful not to distort it. Radius of bending parts should be over 200mm (8inch). Note that pipes cannot be repeatedly bent or stretched; otherwise the material will get harder. Do not bend or stretch the pipe for more than 3 times at the same position. 4.1 Flaring Process (1) Mechanical connectors used indoors shall comply with ISO 14903. When mechanical connectors are reused indoors, sealing parts shall be renewed. When flared joints are reused indoors, the flare part shall be refabricated. (2) Pipework shall be protected from physical damage. (3) Installation of pipework shall be kept to a minimum space required. (4) Do NOT re-use joints and copper gaskets which have been used already. (5) Joints made in installation between parts of refrigerant system shall be accessible for maintenance purposes. (6) Install the refrigerant piping or components in a position where they are unlikely to be exposed to any substance which may corrode components containing refrigerant, unless the components are constructed of materials that are inherently resistant to corrosion or are suitably protected against corrosion. (7) After completion of field piping for split systems, the field pipework shall be pressure tested with an inert gas and then vacuum tested prior to refrigerant charging, according to the following requirements; field-made refrigerant joints indoors shall be tightness tested. The test method shall have a sensitivity of 5 grams per year of refrigerant or better under a pressure of at least 0.25 times the maximum allowable pressure. No leak shall be detected. (8) Use pipe cutter to cut the connection pipe in case it is unshaped. (9) Keep the pipe downward in case cutting scraps get into the pipe. Clear away the burrs after cutting. (10) Remove the flared nut connecting indoor connection pipe and outdoor unit. Then use flaring tool to fix the flared nut into the pipe (as shown in Fig.4.1). (11) Check if the flared part is flaring evenly and if there is any crack. d2 d1 d2 90°±1° d1 Fig. 4.1 61
GREE Multi Variable Air Conditioners Indoor Unit
4.2 Pipe Bending
(1) Reshape the pipe by hand. Be careful not to damage the pipe.
(2) Do not bend the pipe over 90°.
(3) If pipe is repeatedly bent or stretched, it will get hard and difficult to bend and stretch againch
Therefore, do not bend or stretch the bend for over 3 times.
(4) In case that direct bending will open cracks to the pipe, first use sharp cutter to cut the insulating
layer, as shown in Fig. 4.3. Do not bend the pipe until it is exposed. When bending is done, wrap
the pipe with insulating layer and then secure it with adhesive tape.
Fig. 4.2 Fig. 4.3
4.3 Indoor Pipe Connection
(1) Remove pipe cover and pipe plug.
(2) Direct the flared part of copper pipe to the center of screwed joint. Twist on the flared nut tightly
by hand, as in Fig. 4.4 (Make sure indoor pipe is correctly connected. Improper location of the
center will prevent flared nut from being securely twisted. Thread of nut will get damaged if the
flared nut is twisted forcibly).
(3) Use torque wrench to twist on the flared nut tightly until the wrench gives out a click sound (Hold
the handle of wrench and make it at right angle to the pipe. as in Fig. 4.5).
①
Use sponge to wrap the un-insulated connection pipe and joint. Then tie the sponge tightly with plastic tape.
②
Connection pipe should be supported by a bearer rather than the unit.
③
The bending angle of piping should not be too small; otherwise the piping might have cracks. Please use a pipe
bender to bend the pipe.
④
When connecting IDU with connection pipe, do not pull the big and small joints of IDU with force in case the
capillary tube or other tubes have cracks and cause leakage.

For example: Keep pipe size equal to or greater than that of the connecting pipe. Install the drain piping as shown and take measures against condensation. Improperly rigged piping could lead to leaks and eventually wet furniture and belongings. When directly connecting a hard vinyl chloride pipe joint to the drain hose connected to the indoor unit, use a commercially available hard vinyl chloride pipe joint (nominal diameter 13mm (1/2 inch)). Drain hose connected to the indoor unit Commercially available hard vinyl chloride pipe joint (nominal diameter 13mm(1/2 inch)), Commercially available hard vinyl chloride pipe(nominal diameter 13mm(1/2 inch)) Do not connect the drain piping directly to sewage pipes that smell of ammonia. The ammonia in the sewage might enter the indoor unit through the drain pipes and corrode the heat exchanger. 63
GREE Multi Variable Air Conditioners Indoor Unit 5.2 Installing the Drain Pipes Insert the drain hose into the drain outlet, and tighten the clamp securely with tape. Tighten the clamp until the screw head is less than 4mm (3/16 inch) from the hose. Insulate the pipe clamp and the drain hose using heat insulation sponge. Install water trap as shown below. Install one water trap for each unit. Installation of water trap shall consider easy cleaning in the future.

ONLY authorized persons may replace the sensor. (2) The sensor has a lifetime of 15 years. At the end of sensor lifetime or when the sensor fault, the indoor unit or wired controller displays error code "yd", and emits an alarm sound. The alarm can be canceled by operating the “On/Off” button of the wired controller or remote control. The indoor unit fan will keep running and the system can not operate until the sensor is replaced. Please contact our designated dealer or local service center to replace the sensor. (3) The R32 refrigerant leakage sensor is a semiconductor detector which may incorrectly detect substances other than R32 refrigerant. Avoid using chemical substances (e.g. organic solvents, 83
GREE Multi Variable Air Conditioners Indoor Unit hair spray, paint) in high concentrations, in the close proximity of the indoor unit because this may cause misdetection of the R32 refrigerant leakage sensor. (4) When the sensor detects refrigerant leak, the indoor unit or wired controller displays error code "yb", and emits an alarm sound. The alarm can be canceled by operating the “On/Off” button of the wired controller or remote control. The indoor unit fan will keep running and the system can not operate until the leakage is repaired. Please contact our designated dealer or local service center. (5) If the indoor unit report a refrigerant leak and returns to normal after a while, it may be a misdetection caused by other chemical substances. 84
