Note 1: The specifications shown in the table are for one module.
Note 2: Make sure to decide a rated flow rate per module within this flow rate range. The flow rate changes automatically
according to the load fluctuation by the internal invertor pump.
Note 3: When the heat pump starts, it can be used within the following range within 1 hour only. However, during this time,
the required inlet/outlet temperature difference may not be achieved.
Cooling: Chilled water inlet 45°C or less, Cold water outlet 35°C or less
Heating: Hot water inlet 10°C or more, Hot water outlet 20°C or more
In addition, if the operating range will exceed 1 hour, install a bypass in the water piping system if necessary so that
the operation does not exceed the operating range shown in the table above.
Note 4: The warm water outlet temperature is limited by outside air temperature conditions as shown below.

Note 5: Capability is not guaranteed at -20°C to -25°C. Due to the influence of the wind, snow, the surrounding environment,
etc., the ability may not be demonstrated even in the temperature range of -20°C or higher (60HP (Powerful heating
type) only).
Note 6: When calculating holding water volume, calculate the smallest water volume for the piping flow passage, taking the
bypass channel and other factors into consideration. The holding water volumes shown in the table are values for a
designed outlet/inlet temperature differential of ΔT = 10ºC and for the values in (parentheses) a designed outlet/inlet
temperature differential of ΔT = 16ºC. Use straight line interpolation to calculate any other designed outlet/inlet
temperature differentials.
Note 7: Heat pump only.
Note 8: Built in inverter pump model OAT range: -15°C to 46°C
Pump-less model OAT range: -15°C to 52°C
