Facility Setting (Cooling At Low Outdoor Temperature) - Daikin RXS24LVJU Installation Manual

CAUTION
• When connecting the connection wires to the terminal block
using a single core wire, be sure to perform curling.
Problems with the work may cause heat and fires.
• If the stranded wires must be used, make sure to use the round
crimp-style terminal for connection to the power supply terminal
block. Place the round crimp-style terminals on the wires up to
the covered part and secure in place.
• Ground terminal installation
Use the following method when installing the
round crimp-style terminal.
3) Pull the wire and make sure that it does not disconnect. Then fix the wire in place with a wire stop.
Facility Setting
(cooling at low outdoor temperature)
This function is designed for facilities such as equipment or computer rooms. It is never to be used in a
residence or office where people occupy the space.
1) You can expand the operation range to 14°F (–10°C) by turning on switch B (SW4) on the PCB. If the outdoor temperature falls
to –0.4°F (–18°C) or lower, the operation will stop. If the outdoor temperature rises, the operation will start again.
CAUTION
• If the outdoor unit is installed where the heat exchanger of the unit is exposed to direct wind, provide a windbreak wall.
• Intermittent noises may be produced by the indoor unit due to the outdoor fan turning on and off when using facility settings.
• Do not place humidifiers or other items which might raise the humidity in rooms where facility settings are being used.
A humidifier might cause dew condensation from the indoor unit outlet vent.
• Use the indoor unit at the highest level of airflow rate.
