333INSTALLATION SPACE Caution ●●The installation space shown in the following examples is based on an ambient temperature under cooling operation of 95 °F DB (35 °C DB) at the air intake of the outdoor unit. Provide more space around the air intake than shown in the examples if the ambient temperature exceeds 95 °F DB (35 °C DB) or if the thermal load of all of the outdoor units exceeds the capacity.
PAGE 78
3333333MULTIPLE OUTDOOR UNIT INSTALLATION Provide at least 1in. (25mm) of space between the outdoor units if multiple units are installed. ●● When routing the piping from the side of an outdoor unit, provide space for the piping. ●● No more than 3 units must be installed side by side. ●● When 3 units or more are arranged in a line, provide the space as shown in the following example when an obstruction is present also in the upward area.
PAGE 79
33333BRANCH BOX The branch box can be installed onto the wall or hanging from the ceiling. ●● The branch box can be installed and set horizontally or vertically. ●● Provide a service access for maintenance and inspection purposes as shown in the figure ●● below. It is not necessary to provide drainage for the branch box. ●● The slope of the top side must be within ±5° in all directions of the horizontal plane.
PAGE 80
3333333VERTICAL INSTALLATION A vertical installation can only be performed when mounting on the wall. ●● (A vertical installation cannot be hung from the ceiling.) Be sure to install the control box so that the top side faces up. ●● The positioning of the control box cannot be changed when performing a vertical installation.

222PIPING DESIGN 22222 IMPORTANT ITEMS WHEN USING NEW REFRIGERANT (R410A) R410A operates at higher pressure and has less solubility with mineral oil than traditional R22 refrigerant. Therefore, the lubricant and a part of pipe material are different. Some special tools are necessary. REFRIGERANT PIPING MATERIAL AND WALL THICKNESS It is necessary to use seamless copper tubes for refrigerant use. Thickness of tubes are shown in table below. Endurance pressure of the pipe must be 609 psi (4.2 MPa).

1111 REFRIGERANT CONCENTRATION PRECAUTIONS The system designer and installer are to ensure that the system adheres to all local regulations regarding refrigerant leakage. 111111 INTRODUCTION Designing HFI systems requires special attention to codes and standards relating to Refrigeration Concentration Limit (RCL). The RCL is intended to “reduce the risks of acute toxicity, asphyxiation and flammability hazards in normally occupied, enclosed spaces”.
PAGE 377
111111 CHECKING CONCENTRATION LIMIT Check concentration limit following steps , and take appropriate measures depending on the situation.  Calculate amount of refrigerant [lbs. (kg)] per refrigerant system. Amount of refrigerant per refrigerant system Amount of factory charged refrigerant + Amount of additional refrigerant Amount of refrigerant added to system based on pipe length, pipe size and indoor units.
PAGE 378
111111 REFRIGERATION CONCENTRATION COUNTERMEASURES When the concentration limit is exceeded, the designer will need to change the original design or use one of the countermeasures below to reduce potential exposure to refrigerant. Always consult local codes to ensure proper design. ●●Countermeasure 1 Provide opening for ventilation. Provide 0.15% or more opening to floor space both above and below or provide opening without door. (0.15% floor opening based on standard ceiling height of 8.8 ft. (2.

[Installation precautions] When inside the ceiling is high temperature and high humidity Contents When the indoor unit is installed where the inside of the ceiling is 30°C (86°F) RH80% or greater, the dew point temperature of the outer perimeter may become higher than the cabinet surface temperature and moisture will condense on the surface of the cabinet and water drops may fall inside the room. →Refer to Fig.
PAGE 381
[Installation precautions] When installing duct type in ceiling chamber system In the case of the ceiling chamber system (duct is not installed at indoor unit inlet side and room air is sucked into the indoor unit through the inside of the ceiling), the thermistor inside the indoor unit may not correctly detect the room temperature. Heating operation: Room is not heated because the indoor unit is easily turned off by the thermostat.
