▪ Operation range of water flow rate is 13.2-39.6 gpm (50-150 L/min).
(21.2-39.6gpm(80-150L/min)incaseofantifreezeusage.)
▪ The unit is designed for the following operation range;
Entering water temperature: 67-95°F (20-35°C)
Relative humidity below 80%
Water flow rate: 15.9 gpm (60 L/min) or more
▪ During cooling operation when the outside temperature is very
low, it is possible that the thermostat switches off automatically in
order to protect the unit from freezing.
▪ Holdambienttemperatureat35-104°FDB(2-40°CDB).
Heat release from the unit (approx.): RWEQ96: 2730 Btu/h (0.8 kW),
