*1 Under normal heating conditions at the outdoor temperature of 16ºCDB/12ºCWB (60.8ºFDB/53.6ºFWB), the
outlet water temperature of 65ºC (149ºF), and the inlet water temperature of 17ºC (62.6ºF)
*2 Under normal heating conditions at the outdoor temperature of 7ºCDB/6ºCWB (44.6ºFDB/42.8ºFWB), the
outlet water temperature of 65ºC (149ºF), and the inlet water temperature of 9ºC (48.2ºF)
*3 Under normal heating conditions at the outdoor temperature of 7ºCDB/6ºCWB (44.6ºFDB/42.8ºFWB), the
outlet water temperature of 65ºC (149ºF), and the inlet water temperature of 15ºC (59.0ºF)
*4 Under normal heating conditions at the outdoor temperature of 7ºCDB/6ºCWB (44.6ºFDB/42.8ºFWB) when the
unit is set to the "Capacity Priority" mode through the dry NC-contact
• Due to continuing improvements, specifications may be subject to change without notice.
• Do not use steel pipes as water pipes.
• Keep the water circulated at all times. Blow the water out of the pipes if the unit will not be used for an extended
period of time.
• Do not use ground water or well water.
• Do not install the unit in an environment where the wet bulb temperature exceeds 32ºC.
• The water circuit must be a closed circuit.
• There is a possibility that the unit may abnormally stop when it operates outside its operating range. Provide
backup (ex. boiler start with error display output signal (blue CN511 1-3)) for abnormal stop.
• In a system in which the ascent rate of inlet water temperature becomes 5 K/min or above instantly or
1 K/min or above continuously, this model of units cannot be used.
