This document provides instructions for installing an outdoor unit and refrigerant piping for an air conditioning system. 

* The base of the outdoor unit should be installed on a foundation.
* If using a vibration-proof mat, it should be positioned the same way as the base.
* When installing the unit on a field-supplied frame, use metal plates to adjust the frame width for stable installation.
* The recommended metal plate size is 3-15/16 inches or more, with a material of hot-rolled mild steel plate (SPHC) and a thickness of 4.5T.

**Refrigerant Piping Work:**

* Use refrigerant R410A in the refrigerant cycle.
* Do not use oxygen, acetylene, or other flammable or poisonous gases for leakage or air-tightness tests.
* Use compressed air, nitrogen, or refrigerant for these tests.
* Prepare locally-supplied copper pipes and select the appropriate size from Table 5.1.
* Clean the copper pipes to ensure no dust or moisture is present. Blow the inside of the pipes with nitrogen or dry air to remove any foreign materials.

**Refrigerant Pipe End Cautions:**

* When installing a pipe through a wall, secure a cap at the end of the pipe.
* Do not place the pipe directly on the ground.
* Cap the end of the pipe when it is to be inserted through a hole.
* Attach a cap or vinyl tape to the end of the pipe to prevent rainwater from entering. 

**Flaring Dimension:**

! Piping Thickness and Material Use the pipe as below.

Table 5.1 Piping Size in. (mm)

The provided text fragment appears to be an incomplete excerpt from a larger document related to piping systems. It mentions "Piping Thickness and Material" and refers to "Table 5.1" which details "Piping Size in. (mm)". 

However, the text lacks crucial information to provide a meaningful summary. We need to know:

* **What is the context of this information?**  Is it part of a design specification, a material selection guide, or something else?
* **What are the specific contents of Table 5.1?**  What are the different pipe sizes listed, and what are the corresponding thicknesses and materials for each? 

Without this missing information, it's impossible to provide a comprehensive summary. 

! Flare Nut Dimension Use the flare nut as below.

<Flare Nut Dimension B in.(mm)

This excerpt appears to be the beginning of a table or guide related to "Flare Nut Dimensions." It specifically mentions using the flare nut in a certain way, but the table itself is incomplete. 

The table seems to be organized with two columns: 

* **"Flare Nut Dimension"**: This column likely refers to the physical dimensions of the flare nut, with "B" being a specific dimension (possibly width or diameter). 
* **"Use the flare nut as below"**: This column is likely where the specific applications or instructions for using the flare nut based on its dimension "B" would be listed. 

However, the provided text only shows the column headers and the first row, which only mentions "B in.(mm)" without any actual dimension value.  

To understand the table fully, we need the rest of the table content, including the actual dimensions and their corresponding uses.

Table 5.2 Limitation of Outdoor Unit

This excerpt from a document appears to be discussing refrigerant piping work for outdoor units. It specifically mentions "Table 5.2 Limitation of Outdoor Unit," which likely contains information about the limitations or restrictions on the installation and configuration of refrigerant piping for outdoor units. 

The text instructs to "Ensure that the directions for refrigerant piping work according to the tables." This suggests that the table provides specific guidelines and limitations for installing refrigerant piping that must be adhered to. 

To understand the specific limitations, we would need to see the actual contents of Table 5.2. 

This table appears to be incomplete. It only shows the header "Indoor Unit Pipe Model in. (mm)" and lacks any actual data. To provide a summary, I need the complete table with the actual pipe model information. 

Please provide the full table or more context about the table's content. 

This table appears to be incomplete. It only shows the numbers "5" and "4" without any context or labels.  To summarize it accurately, I need more information. 

Please provide the following:

* **Table Headers:** What do the rows and columns represent? For example, are they "Indoor Unit Model" and "Outdoor Unit Model"?
* **Table Context:** What is the table about? Is it about compatible combinations, pricing, or something else?

With more information, I can give you a comprehensive and accurate summary. 

The table you provided, "Table 5.5 Limitation of Combination Quantity," is incomplete.  To provide a summary, I need more information about the table's contents. Please share the actual table data (rows and columns) so I can summarize it for you. 

(*1) The connection ratio should not be bigger than 100% for systems where all indoor units may operate at the same time; otherwise, overload operation may occur in harsh conditions or narrow range. (*2) Capacity ratio must be 100% when only one indoor unit is connected, and the refrigerant additional charge should be reduced according to the indoor unit type. Refer to Table 5.10. (*3) The capacity of indoor unit should be modified when the capacity ratio exceeds 100% or the combination quantity exceeds the recommended quantity.

Modified capacity = nominal capacity × correction factor

Correction factors are defined as follows:

This text provides guidelines for connecting multiple indoor units to a single outdoor unit in a heating and cooling system. It outlines limitations and adjustments needed to ensure proper operation. 

* **Connection Ratio:**  The connection ratio, representing the total capacity of indoor units relative to the outdoor unit, should not exceed 100% when all indoor units operate simultaneously. Exceeding this limit could lead to overload under challenging conditions.
* **Capacity Ratio:** When only one indoor unit is connected, the capacity ratio must be 100%. However, the refrigerant charge should be adjusted based on the specific indoor unit type, as detailed in Table 5.10.
* **Capacity Modification:** If the capacity ratio surpasses 100% or the number of connected units exceeds the recommended quantity, the capacity of the indoor units needs to be modified. This is done by multiplying the nominal capacity by a correction factor, which is specific to the situation. 

**Overall, the text emphasizes the importance of adhering to connection and capacity ratios to prevent overload and ensure efficient system performance.**

* **Check for refrigerant leaks.** A large refrigerant leak can lead to serious consequences:
    * **Oxygen deficiency:**  This can be dangerous if the leak occurs in an enclosed space.
    * **Generation of harmful gases:**  A fire can cause chemical reactions with the leaked refrigerant, generating toxic gases.
* **Correct refrigerant charge is essential.**  Charge the correct amount of refrigerant according to the label on the service cover.  An excess or shortage can damage the unit.
* **Special attention to refrigerant gas leakage:**  Be aware of the critical gas concentration to prevent accidental leaks before installing the system.

**The document also provides a diagram of the installation process, including:**

* Liquid line stop valve
* Gas line stop valve
* Nitrogen tank for air-tight testing and nitrogen blow during brazing
* Manifold gauge
* Vacuum pump

**Important note:** The document emphasizes the critical importance of preventing refrigerant leaks due to the potential for oxygen deficiency and harmful gas generation. 

V: Room Volume (ft3(m3))

* This value should be decided according to each country’s regulation such as ISO5149,EN378 and ASHRAE Standard 15. In the case that the calculated critical concentration is higher than this value, take the following actions:

1) Provide a gas leakage detector and exhaust fan controlled by its gas leakage detector.

2) Provide effective opening in the wall or door for ventilation to next door so that the critical gas concentration can be maintained lower than the above value. (Provide an opening with area greater than 0.15% of the floor surface at the lower part of a door.)

CAUTION

1. Maximum Permissible Concentration of HFC GAS R410A

2.

The refrigerant R410A is an incombustible and non-toxic gas. However, if leakage occurs and gas fills a room, it may cause suffocation. Once leakage occurs, it is a must to take effective actions to make the concentration of R410A lower than 0.026 lbs/ft3 (0.42 kg/m3). Calculation of Refrigerant Concentration (1) Calculate the total quantity of refrigerant R (lbs(kg)) charged in the system connecting all the indoor units of target rooms. (2) Calculate the volume of the room installing this unit V (ft3(m3)). Calculate the refrigerant concentration C (lbs/ft3) (kg/m3) of the room according to the above equation.

3.

Please follow local codes or regulations, if any.

5.7 Caution of the Pressure by Check Joint

When the pressure is measured, use the check joint of gas stop valve ((A) in the figure below) and use the check joint of liquid piping ((B) in the figure below). At that time, connect the pressure gauge according to the following table because of high pressure side and low pressure side changes by operation mode.

This document provides safety guidelines for handling refrigerant R410A in air conditioning systems. It emphasizes the importance of ventilation and monitoring for potential gas leaks. 

* **Room Volume:** The volume of the room (V) is crucial for determining safe refrigerant concentration levels. It should be calculated according to local regulations like ISO5149, EN378, and ASHRAE Standard 15.
* **Maximum Permissible Concentration:** The maximum permissible concentration of R410A is 0.026 lbs/ft3 (0.42 kg/m3). Exceeding this level poses a suffocation risk.
* **Leakage Mitigation:** If the calculated critical concentration is higher than the permissible limit, the following measures should be taken:
    * Install a gas leakage detector and exhaust fan.
    * Provide adequate ventilation by creating an opening in the wall or door (at least 0.15% of the floor surface).
* **Refrigerant Concentration Calculation:**  The document outlines a two-step process to calculate the refrigerant concentration in a room:
    1. Determine the total refrigerant charge (R) in the system.
    2. Calculate the refrigerant concentration (C) using the formula C = R/V.
* **Pressure Measurement:**  When measuring pressure, use the appropriate check joint (A or B) on the gas stop valve or liquid piping based on the operating mode and the pressure side.

**Overall, the document highlights the potential hazards of R410A leaks and provides practical steps to ensure safe handling and prevent dangerous situations.** 

NOTE: Be careful that refrigerant and oil do not splash onto the electrical parts when removing the charge hoses.

## Summary of Sections 5.9 and 6: Refrigerant Collection and Electrical Wiring

**Section 5.9: Collecting Refrigerant**

This section provides instructions for collecting refrigerant when relocating an air conditioning system. It outlines the following steps:

1. **Connect the manifold gauge:** Attach the gauge to both the gas and liquid stop valves.
2. **Turn on the power:** Start the system and set the outdoor unit PCB to "ON" for cooling operation.
3. **Close the liquid stop valve and collect refrigerant:** This will draw refrigerant from the system.
4. **Monitor pressure:** As refrigerant is collected, the pressure at the gas stop valve will decrease. When it reaches -1.45 psi (-0.01 MPa), immediately:
    * Close the gas stop valve.
    * Set the DSW1-1 pin to "OFF" to stop the unit.
5. **Turn off the power:** Once the refrigerant is collected, shut off the power to the system.

**Important Note:** The low pressure should never be allowed to drop below -1.45 psi (-0.01 MPa). If it does, the compressor may be damaged.

**Section 6: Electrical Wiring**

This section focuses on safety precautions and guidelines for electrical wiring work:

* **Turn off power:** Always disconnect the main power switch to both the indoor and outdoor units before performing any electrical work, and wait at least 10 minutes.
