NOTES:
• Specifications are based on the following conditions:
– Cooling: Indoor temperature of 80 °FDB/67 °FWB(26.67 °CDB/19.44 °CWB), and outdoor temperature of 95 °FDB/75 °FWB (35 °CDB/23.9 °CWB).
– Heating: Indoor temperature of 70 °FDB/59 °FWB (21.11 °CDB/15 °CWB), and outdoor temperature of 47 °FDB /43 °FWB (8.33 °CDB/6.11°CWB).
– Standard static pressure: 0.10 inWG (25 Pa)
– Pipe length: 24 ft 7 in (7.5 m), Height difference: 0 m. (Between outdoor unit and indoor unit.)
• Protective function might work when using it outside the operation range.
• *1: Maximum current:
– The maximum value when operated within the operation range.
– The total current of indoor unit and outdoor unit.
• *2: Sound pressure level:
– Measured values in manufacturer’s anechoic chamber.
– Because of the surrounding sound environment, the sound levels measured in actual installation conditions might be higher than the specified values here.
• *3: Available on Google Play

8-1. External input
• “Operation/Stop” mode or "Forced stop" mode can be selected with function setting of indoor unit.
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 492 ft (150 m).
• The wire connection should be separate from the power cable line.
Indoor unit functions such as Operation/Stop can be done by using indoor unit terminals.

3) Room temperature control for indoor unit sensor
Depending on the installed environment, correction of the room temperature sensor may be re-
quired. Select the appropriate control setting according to the installed environment.
The temperature of the room temperature sensor is corrected as follows:
Corrected temp. = Temp. of the room temp. sensor - Correction temp. value
Example of correction:
When the temperature of the room temp. sensor is 78°F and the setting value is “03” (-2°F),
the corrected temp. will be 80°F (78°F - [-2°F]).
The temperature correction values show the difference from the Standard setting “00” (manufactur-
er’s recommended value).

NOTES:
• Specifications are based on the following conditions:
– Cooling: Indoor temperature of 80 °FDB (26.67 °CDB) / 67 °FWB (19.44 °CWB), and outdoor temperature of 95 °FDB (35 °CDB) / 75 °FWB (23.9 °CWB).
– Heating: Indoor temperature of 70 °FDB (21.11 °CDB) / 59 °FWB (15 °CWB), and outdoor temperature of 47 °FDB (8.33 °CDB) / 43 °FWB (6.11 °CWB).
– Pipe length: 24 ft 6 in (7.5 m), Height difference: 0 ft (0 m). (Between outdoor unit and indoor unit.)
• Protective function might work when using it outside the operation range.
• *1: Sound pressure level
– Measured values in manufacturer’s anechoic chamber.
– Because of the surrounding sound environment, the sound levels measured in actual installation conditions might be higher than the specified values here.

stalled.
• When routing the piping from the side of an outdoor unit, provide space for piping.

NOTES:
• If the space is larger than stated above, the condition will be the same as when there is no ob-
stacle.
• When installing the outdoor unit, be sure to open the front and left side to obtain better operation
efficiency.
CAUTION
• Do not install the outdoor unit in two-stage where the drain water could freeze. Otherwise the
drainage from the upper unit may form ice and cause a malfunction of the lower unit.
• When the outdoor temperature is 32 °F (0 °C) or less, do not use the accessory drain pipe and
drain cap. If the drain pipe and drain cap are used, the drain water in the pipe may freeze in
extremely cold climate. (For reverse cycle model only.)
• In area with heavy snowfall, if the inlet and outlet of the outdoor unit is blocked with snow, it
might become difficult to get warm, and it is likely to cause product malfunction. Construct a
canopy and a pedestal, or place the unit on a high stand that is locally installed.
