2 SAFETY PRECAUTION

Cautions for using with the outdoor unit which adopts R407C refrigerant.

· Do not use the existing refrigerant piping.

-The old refrigerant and refrigerant oil in the existing piping contains a large amount of chlorine which may cause the refrigerant oil of the new unit to deteriorate.

· Do not use copper pipes which are broken, deformed or discolour .

In addition, be sure that the inner surfaces of the pipes are clean, free of hazardous sulphur and oxides, or have no dust /

dirt, shaving particles, oils, moisture or any other contamination.

-If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the refrigerant oil will result.

· Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before brazing. (Store elbows and other joints in a plastic bag.)

-If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.

· Use ester oil, ether oil or alkyl benzene (small amount) as the refrigerant oil to coat flares and flange connections.

-The refrigerant oil will degrade if it is mixed with a large amount of mineral oil.

Use liquid refrigerant to fill the system.

-If gas refrigerant is used to fill the system, the composition of the refrigerant in the cylinder will change and performance

may drop.

· Do not use a refrigerant other than R407C.

-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the refrigerant oil to deteriorate.

· Use a vacuum pump with a service port.

-The vacuum pump oil may flow back into the refrigerant cycle and cause the refrigerant oil to deteriorate.

· Do not use the following tools that are used with conventional refrigerant. (Gauge manifold , charge hose, gas leak detector, reverse flow check valve, refrigerant charge base, vacuum gauge,

refrigerant recovery equipment)

-If the conventional refrigerant and refrigerant oil are mixed in the R407C, the refrigerant may deteriorated.

-If water is mixed in the R407C, the refrigerant oil may deteriorate.

-Since R407C does not contain any chlorine, gas leak detectors for conventional refrigerant will not react to it.

· Do not use a charging cylinder.

-Using a charging cylinder may cause the refrigerant to deteriorate.

· Be especially careful when managing the tools.

-if dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deteriorate.

· Do not use the drier which is sold in the field.

-The drier for R407C refrigerant is pre-attached to outdoor unit refrigerant circuit.

-Some drier in the field are not in conformity with R407C refrigerant.

5-1. COOLING AND HEATING CAPACITY AND CHARACTERISTICS

5-1-1. Method for obtaining system cooling and heating capacity:

To obtain the system cooling and heating capacity and the electrical characteristics of the outdoor unit, first add up the ratings of all the indoor units connected to the outdoor unit (see table below), and then use this total to find the standard capacity with the help of the tables on page 11 to 14.

(1) Capacity of indoor unit

(2) Sample calculation

1 System assembled from indoor and outdoor unit (in this example the total capacity of the indoor units is greater than that of the outdoor unit)

• Outdoor unit PUMY-P125YMA

• Indoor unit PKFY-P25VAM-A o 2 , PLFY-P50VLMD-A o 2 2 According to the conditions in 1 , the total capacity of the indoor unit will be: 28 o 2 + 56 o 2 = 168

5-1-2. Method for obtaining the heating and cooling capacity of an indoor unit:

(1) The capacity of each indoor unit (kW) = the capacity A (or B ) o

(2) Sample calculation (using the system described above in 4-1-1. (2) ):

During cooling: During heating:

• The total model capacity of the indoor unit is:

2.8 o 2 + 5.6 o 2=16.8kW Therefore, the capacity of PKFY-P25VAM-A and PLFY-P50VLMD-A will be calculated as follows by using the formula in 4-1-2. (1):

Model 25=14.6 o = 2.43kW

Model 50=14.6 o = 4.87kW

Model 25=16.33 o = 2.75kW

5-3-1. Correcting Changes in Air Conditions

(1)The performance curve charts (Figure 1, 2) show the rated capacity (total capacity) under the stated conditions when standard

length for piping (5m) is used. The rated power is derived from the capacity ratio and power ratio obtained for the indoor and outdoor intake temperatures at time 1.

• Standard conditions:

• Use the rated capacity and rated power values given in the characteristics table for each indoor unit.

• The capacity is the single value on the side of the outdoor unit; the capacity on the sides of each indoor unit must be added to obtain the total capacity.

(2)The capacity of each indoor unit may be obtained by multiplying the total capacity obtained in (1) by the ratio between the

individual capacity at the rated time and the total capacity at the rated time.

Individual capacity under stated conditions = total capacity under the stated conditions o

(1) During cooling, to obtain the ratio (and the equivalent piping length) of the outdoor units rated capacity and the total

in-use indoor capacity, first find the capacity ratio corresponding to the standard piping length (5m) from Figures 3 at first, and then multiply by the cooling capacity from Figure 1 to obtain the actual capacity.

(2) During heating, to find the equivalent piping length, first find the capacity ratio corresponding to standard piping length (5m)

from Figure 4, and then multiply by the heating capacity from Figure 2 to obtain the actual capacity.

(3) Method for Obtaining the Equivalent Piping Length

Equivalent length for type 125 = (length of piping to farthest indoor unit) + (0.35 o number of bends in the piping) (m)

Length of piping to farthest indoor unit: type 125.....70m

5-3-3. Correction of Heating Capacity for Frost and Defrosting

If heating capacity has been reduced due to frost formation or defrosting, multiply the capacity by the appropriate correction factor from the following table to obtain the actual heating capacity.

Concerning the Compressor

This system has a scroll compressor. This compressor uses a low pressure shell that typically has a temperature in the range 30-80°C. In addition, compressor wiring should be in the direction of rotation to the right. Wire colors are red (U), white(V), black (W), yellow and yellow (thermal switch).

8-3-1. Operating a Single Refrigerant System

When operating either alone or as part of a group, a M-NET remote controller (NR) may be used to control a single refrigerant system that does not overlap with any other system.

Using a M-NET remote controller (NR)

✽ Address setting must be performed. ✽ The NR wire and indoor and outdoor transmission wires must be a non-polar two wire cable. ✽ One NR may be connected to a maximum of 16 indoor unit. ✽ Two NR units may be used to perform control tasks (the second one pressed will have priority if two are pressed

simultaneously).

✽ For the system utilizing R-Converter units (PAC-SF29LB), the following systems are not available. Group operation

system, centralized controller, group remote controller, etc. (See the installation manual of R-Converter units.)

✽ If the user plans to install multiple refrigerant

systems and a centralized controller in the future, it is strongly suggested that a NR be used.

3) There may be a maximum of two controllers when a group has 16 indoor units or less.

4) The transmission wire must have a power supply when an SC is used. Please connect the power supply for the transmission wire to the centralized controller transmission wire.

SC with 2 units or less SC with 3 to 5 units

5) Use a shielded wire (at least 1.25mm
