WARNING

This system should be applied to places of office, restaurant, residence and the like. Appliaction to inferior environment such as engineering shop could cause equipment malfunction. Please entrust installation to either the company which sold you the equipment or to a professional contractor. Defects from improper installations can be the cause of water leakage, electric shocks and fires. Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage, electric shocks and fires. When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration. In regards to preparing this countermeasure, consult with the company from which you purchased the equipment, and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold concentration does occur,there is the danger of a resultant oxygen deficiency accident. For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result from a falling of the unit. Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit. For electrical work, please see that a licensed electrician executes the work while following the safety standards related to electrical equipment, and local regulations as well as the installation instructions, and that only exclusive use circuits are used. Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks and fires. Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to the terminal connection part, through properly securing it. Improper connection or securing can result in heat generation or fire.

Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation can

also result in heat generation or fire.

(4) Watch the status of outdoor unit compressor, disconnect the general power supply for the air conditioner assembly after the compressor unit starts.

If the hi-pressure valve of the outdoor unit is 3-way valve: Without starting the machine, simply exhaust to vacuum (vacuum degree<200Pa) directly from hi-presser and low-pressure valves(strictly in compliance with operation steps defined in instruction manual for outdoor unit) after machine connecting pipe is well done.

Vacuumize 2~3 hours according to the length of the pipe. When vacuumizing, confirm the gas side and liquid side of the 2-way valve and 3-way valve shall be in full close state. When it is not lower than 200Pa after 2 hours or more vacuumizing, vacuumize for another 1 hour. If after more than 3 hours vacuumizing it is still not lower than 200Pa, the leak part shall be found. When it is lower than 200Pa after more than 2 hours vacuumizing, close both the valve VL and VH of the diverter, then close the vacuum pump. Place it there to observe if the vacuity changes. If it changes, it indicates leakage exists, so the leak part shall be found. After finishing the above vacuumizing work, replace the vacuum pump with refrigerant tank and turn to the refrigerant charging procedure.

V Charging of refrigerant

1.Calculation of additional charging amount of refrigerant

After finishing vacuumizing work, replace the vacuum pump with refrigerant tank and turn to the refrigerant additional charging procedure.

Calculation of additional charging amount of refrigerant

Quantity of filled refrigerant before the machine leaving factory does not consider supplement for extension tubes while spot installation. After practical installation is finished, it is necessary to fill supplement refrigerant into extension tubes provided that the length of spot liquid tube>0m. Filling method is as the following.

Calculation method:

Quantity of supplement refrigerant is determined by specification and actual length of the spot liquid tube.

Calculation formula:

Quantity of spot supplement refrigerant = actual length necessary supplement refrigerant quantity per meter of the tube. E.g.: Uuantity of spot supplement refrigerant(R407C)=(L1-5) 0.035kg/m) L1: Actual total length of 6.35 liquid tube in one system Uuantity of spot supplement refrigerant(R407C)=[(L2-5)+(L3-5)] 0.035kg/m) L2, L3: Actual length of 6.35 liquid tube in the B1, B2 way.

2.Charging of refrigerant

Close all valves of outdoor unit, and charge refrigerant from air discharge valve of gas side. When can not charge the specified amount, firstly, open all the valves, both liquid side and gas side, of outdoor unit,then switch the valve of gas side to close state a little.Under this condition, do cooling operation and charge refrigerant from the discharge valve of gas side. At this time, adjust the valve of the refrigerant tank to make the refrigerant in Gas State when it is absorbed by system. When refrigerant leakage making refrigerant lack in system occurs, all of the system shall be recovered and recharge it according to specified amount.

3.Opening of the refrigerant pipe

Open all the valves of outdoor unit

Installation procedure Refrigerant

The systems use regrigerangt R407C. This refrigerant itselt is innocuous, noncombustible 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. The concentration limit is the concentration that is not

harmful to human body and can take emergency steps to treat the concentration of Freon.

Concentration limit of R407C:0.3kg/m

Indoor unit

If the indoor unit leaks, all the refrigerant in the syetem will leak out

1.Sequence of refrigerant concentration affirmance Calculate the refrigerant concentration according to the following sequence. (1) Calculate the total refrigerant-charging amount of each of the refrigerating system(kg). Refrigerant charging amount of outdoor system + Additional refrigerant charging amount =Total refrigerant charging amount of the refrigerating equipment(kg). Refrigerant charging amount of outdoor system: Refrigerant charging amount when air conditioner leaves factory. Additional refrigerant charging amount: Additional refrigerant charging amount according to the site pipe length and pipe diameter.

(2) Calculate the minimum size of the room suitable for the indoor unit assembly(m ).

(3) Calculate the concentration of refrigerant: Total refrigerant charging amount of refrigerating equipment/the minimum room size suitable for indoor unit assembly(m ) Refrigerant concentration limit:0.3kg/m

2.Countermeasure when exceeding the concentration limit (1) Set an effective opening for ventilation and fresh air. Cut an intake respectively on the upper and lower part of the door which areas are equivalent to 0.15% grounding area, or cut an intake in other part of the room. (2) Reduce the total refrigerant charging amount of the refrigerating equipment Shorten the refrigerant pipe length. Reduce the installation place distance between the outdoor unit and the indoor unit to shorten the refrigerant pipe length, so that reduce the total refrigerant charging amount of the refrigerating equipment. (3) Establish ventilation and fresh air system Establish a mechanical equipment for fresh air to keep the refrigerant concentration below the concentration limit (normal ventilation). When can not ventilate the normally, please set an alarm apparatus linked with the mechanical ventilation equipment.

Installation procedure Electric wiring

Electric wiring

Note: The air conditioner must use special circuit (over 30A), 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.When wiring,there shall keep a proper distance between the power line and communication wire to avoid twist together.Otherwise,signal disturbance will occur,and the air conditioner can not operate normally. Power supply:1PH,220-230V~,50Hz. The wiring method of power line is Y connection. If the power line is damaged,in order to avoid risk of electric shock, it must be replaced by the manufacturer or its repair center or other similar qualified person.
