▪ 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),
RWEQ120: 3412 Btu/h (1.0 kW), RWEQ144: 4436 Btu/h (1.3 kW)
There is no heat release from the unit if the heat rejection
cancellation is activated.
It is recommended to always ventilate the room if this function is not
activated.
