Notes:
*1.Under normal heating conditions at the outdoor temperature of 80.6ºFDB/71.2ºFWB (27.0ºCDB/21.8ºCWB), the outlet water temperature of 120ºF (49ºC),
and the inlet water temperature of 70ºF (21ºC) This condition is based on 10 CFR.
*2.Under normal heating conditions at the outdoor temperature of 80.6ºFDB/71.2ºFWB (27.0ºCDB/21.8ºCWB), the outlet water temperature of 149ºF (65ºC),
and the inlet water temperature of 70ºF (21ºC) This condition is based on 10 CFR except for outlet water temperature.
(Outlet water temperature is based on typical operating temperatures.)
*3.The temperature difference between inlet water and outlet water must be kept above the following values.
Energy saving operation 1 mode ··· ΔT=50°F (28ºC)
Energy saving operation 2 mode ··· ΔT=50°F (28ºC)
Max capacity operation ··· ΔT=67°F (37ºC)
If the unit is operated with the inlet-outlet water temperature difference at or below the ΔT listed above, the flow rate will reach its maximum, which can adversely
affect the normal operation of the unit and shorten product life.
Note that, regardless of the inlet-outlet water temperature difference (even during operation within the range with the minimum water inlet-outlet temperature
difference), the higher the inlet temperature, the lower the COP.
Keep the inlet water temperature as low as possible to ensure efficient operation.
*4.The sound pressure level is a value measured in an anechoic room in accordance with the conventional method in JRA4060.
*5.PT-NPT reducers are included as accessories.
*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 90ºF (32°C).
*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 (9ºF/min) or above instantly or 1 K/min (1.8ºF/min) or above continuously,
this model of units cannot be used.
