Indoor temperature : 26.7°C DB, 19.4°C WB(80°F DB, 67°F WB) Outdoor temperature : 35°C DB, 23.9°C WB(90°F DB, 75°F WB), Equivalent refrigerant piping : 7.6m(25ft) , Level differences : 0m(0ft)
*3) Norminal heating capacities are based on; Indoor temperature : 21.1°C DB, 15.6°C WB(70°F DB, 60°F WB) Outdoor temperature : 8.3°C DB, 6.1°C WB(47°F DB, 43°F WB), Equivalent refrigerant piping : 7.6m(25ft) , Level differences : 0m(0ft)
*4) Sound level was acquired in a dead room. Thus actual noise level may be different depending on the installation conditions.*5) Specifications are subject to change without prior notice for product improvement.

The installation space mentioned above is minimum suggested clearance. To secure enough service space and performance of system, take account of more sufficient space. The required minimum space between outdoor units for service and performance of system is at least
100mm(4in).

2 Space requirements
2-3. Installing duct for horizontal exhaust dischargeIt is necessary to install an air-discharge duct (field supply) to direct exhaust from the fan horizontally if it is difficult to provide a minimum space of 2m(6.6 ft) between the air-discharge duct outlet and a nearby obstacle.
2-4. Installing the outdoor unit in harsh environmentsIn abnormally harsh environments such as cold and/or windy areas, sufficient countermeasures to guard against excessive wind and snow should be taken to ensure the unit's correct operation. Snow-proof duct (field supply) should be fitted to the unit and direct exposure to the wind should be avoided as much as possible. When the unit is expected to operate in cooling mode in condition under 10°C(50°F), in snowy areas, in environments subject to strong winds or rain, install air inlet and outlet ducting as shown in the below example
Discharged air
Louver
Suction air
Upper floor
Discharged air
Ex) Balcony Ex) Mechanical room
The frame/foundation should be higher than expected snowfall. The foundation must be solid and the unit must be secured with anchor bolts. Be sure to install unit in a place strong enough to withstand its weight. When installing on a roof subject to strong wind, countermeasures must be taken to prevent the unit form being
overturned. Any lack of strength may cause unit to fall down, resulting in a personal injury. For more detailed information about installation, refer to installation manual.

All wiring, components and materials to be procured on the site must comply with the applicable local and national codes.
The relationship between the starting time and the starting current (Digital Scroll Comp. + Fixed Scroll Comp)
RLA is based on the following conditions. - Indoor temp. : 80˚F DB/ 67˚F WB - Outdoor temp. : 95˚F DB
Voltage range Units are suitable for use on electrical systems where voltage supplied to unit terminal is not below or above listed range limits.
Maximum allowable voltage variation between phases is 2%. Select wire size based on the value of MCA. MFA is used to select the circuit breaker and the ground fault circuit interrupter (earth leakage circuit breaker).

Cautions Correct piping work Wrong piping work
The refrigerant piping should be the same level or lower than connecting position of piping to outdoor units.
Piping work should be run with side direction for better uniform distribution of refrigarant and oil like next diagram.
Outdoor joint kits should be installed in a horizontal direction, even it is a low pressure pipe.
When the piping length between outdoor and branch joints is 2m(6.6 ft) or more, a vertical trap has to be installed like right diagram. 2m(6.6 ft) or overLess than 1m(3.3 ft)
200~300mm (7-3/4~11-3/4in)
2m(6.6 ft) or over
