SAFETY PRECAUTIONS 3 SAFETY PRECAUTIONS Please read these "Safety Precautions" first then accurately execute the installation work. Though the precautionary points indicated herein are divided under two headings, WARNING and CAUTION those points which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the WARNING section.
SAFETY PRECAUTIONS WARNING When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant (please see nameplate) within the refrigeration cycle. Rupture and injury caused by abnormal high pressure can result from such mixing. Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result in water leakage, electric shock, fire and refigerant leakage.

l l l l l l l l l l l work is not met with the requirements, overturn of the unit will occur resulting in accidents. The wiring work shall be done by a qualified person and referred to the “technical standard of electric equipment”, “indoor wiring regulation” and what the manual specified. Do use special circuit. If the capacity of the circuit is not enough or bad work, electric shock, fire and other accidents will happen.
8.8 Special Work and Main Points in Installation Warning l l During installation, if refrigerant l leakage occurs, take ventilation measurement immediately. l As soon as the leaked refrigerant gas meets fire, poisonous gas will generate. After finishing installation, confirm the refrigerant gas does not leak. If the refrigerant gas leaks in the room, once it meets heater, burner and gas stove etc. fire source, the poisonous gas will generate. A.
(4) Pipe connection of the outdoor unit Referring to the installation diagram in page 4, connect the indoor unit, outdoor unit, branch pipe and electronic expansion valve together by using the pipe connection method and welding method. (5) Test of airtight quality After connection of the refrigerant pipes, carry out airtight quality test.
8.9 Test of leakage after wiring work is finished After connection of the refrigerant pipes, carry out leakage test. In this test, pressurize to the pipes as shown in the below figure by using nitrogen tank. Close the valves of the gas side and liquid side totally. The nitrogen may enter the cycle system of the outdoor unit, so that, before pressurizing, the valve rods must be fastened. (Both the gas side and liquid side).
c. Vacuumize 2~3 hours according to the length of the pipe. When vacuuming, confirm the gas side and liquid side of the 2-way valve and 3-way valve shall be in full close state. d. When it is not lower than 200Pa after 2 hours or more vacuuming, vacuums for another 1 hour. If after more than 3 hours vacuuming it is still not lower than 200Pa, the leak part shall be found. e.
8.11 Refrigerant MRV central air conditioner uses refrigerant “R22”. This refrigerant itself is innocuous, non-combustible safety refrigerant. But then, when arranging the air conditioner equipment, it is necessary to take some steps to take precautions against in case of the indoors refrigerant leakage. Such as, the room size shall be taken into account to avoid making the concentration of the refrigerant not exceed the concentration limit and other relevant steps.
8.12 Electric wiring Note: l l l l l l l The air conditioner must use special circuit (over 40A), and wiring by the qualified electrician according to the wiring rules specified in national standard. The grounding wire and the neutral wire shall be strictly separated. Connect the neutral wire with grounding wire is incorrect. The electric leakage breaker must be installed. All the electric wire must be copper wire.
Wiring method 1. Wiring method of orbicular terminals For the connection wire with orbicular terminals, its wiring method is as shown in the right figure: remove the connecting screw, put the screw through the ring on the end of the wire, then connect to the terminal block and fasten screw. 2.
2. Do not connect the power line with different dimensions to the same grounding wire end. Improper contact will affect protection. 3. Keep a proper distance between the communication wire and the power line. Otherwise, abnormal communication will occur because of disturbance. 4. Do not connect the power line to the connecting end of communication wire. Incorrect connection will cause damage of connected unit. 5.The communication wire must be shielding wire.

Installation of receive display Because of the temperature sensitive device, do not install the receive display at straight sunlight place, either in front of air outlet grill, for it is effected greatly from cool air and heat air, the receive display is at least 20mm distance to the air outlet grill. Since there is light sensitive device which receives wireless remote signal, so do not installed behind the window curtain or other obstacles, in order not to obstruct the signal.
Installation of the wired remote controlller a. Remove upper part of wire Remove upper part of wire controller PCB is mounted on lower part of wire controller, be careful not to damage Upper part of wire controller Lower part of wire controller b.

9.3 Defrost operation Flow Chart 1. The compressor operates heating over 25 minutes, after meeting the defrosting condition, it is permitted to enter defrosting. Defrosting process is unit-stop defrosting mode. Determining condition of defrosting is as follows: Unit-stop defrosting: (1) When outdoor ambient temperature is less than 2 , (outdoor ambient temperaturedefrosting sensor) is more than 9 , and keeping over 2 minutes, enter unit-stop defrosting.
2. Compressor control The compressor will start at 10Hz and running between 30Hz to 120Hz. In operation the compressor running frequency is determined by three elements : the number of indoor units in operation , the temperature difference of each indoor units between setting temperature and room temperature , the size of each indoor unit. 3.
10 DIAGNOSTIC INFORMATION (TROUBLE SHOOTING) 10.1 Fault Codes In order to make repair and maintenance convenient, we set “Automatic troubleshooting” function in indoor unit and centralized controller. If any abnormal phenomenon occurs in operation, you can determine the trouble part and condition from the display on the LED of outdoor PCB, or the trouble code on the wired controller.
10.2 AU48- diagnostic information and trouble shooting The failure code is displayed on the outdoor PCB; please diagnose the trouble according to the following code: Failure code Failure position Judgment measure 01 Outdoor defrosting sensor TE circuit 02 Ambient circuit temp. sensor TA Examine the sensor below 20H in cut circuit or over 1000H in short circuit for continuous 60 seconds, recoverable 03 Suction circuit temp.
minutes normally 14 Low pressure protection acts Cooling: examine Ps below 0.2kgG/cm2 for 30 （Ps） seconds continuously after compressor starts up; Heating: examine Ps below -0.2kgG/cm2 for 10 minutes continuously after compressor starts up; recoverable 15 High pressure protection acts （Pd） Examine sensor Pd over 27.5kgG/cm2 16 Suction temp. protection acts （TS） On compressor working, for continuous 10 minutes, examine sensor TS over 40℃, recover after 2 minutes.
10.3 Troubleshooting (1) Indoor unit trouble indication: timer indicator flashes (once, twice, 3 times, 7 times) Abnormal reasons: Heat sensitive resister is short circuit or open circuit The treatment to sensor output part in PC board is improper, such as poor contact of package part, the electrolytic capacitor for filtering is failed, etc. Treatment: Remove the heat sensitive resister, test and measure its numerical value.
Treatment: use the DC voltage grade of multimeter to test the plastic sealed motor to find if there is any feedback signal, determine if the plastic sealed motor is abnormal. If normal, change the indoor unit PC board. (6) Indoor unit trouble indication: Timer indicator flashes (12 times) Abnormal reason: Indoor unit PC board is improper Treatment: change the improper indoor unit PC board.
Refrigerant leaks Discharging air temperature heat sensitive resistor is improper Electronic expansion valve or 2-way valve is closed Treatment: check if there is leakage part, test system pressure in rated operation state to determine if there is leakage? Check the state of electronic expansion valve and 2-way valve. Test and measure the numerical value of discharging air temperature heat sensitive resister.
