If using the product after being left idle for an extended period of time,
make sure to open the airvent valve to release air.
• Running water noises may occur inside, or cooling/heating performance
may degrade.
• Use a bucket or hose to catch water. If using Cool mode only, in the winter
season, make sure to remove stagnant water to prevent the product from
freezing and bursting. After drainage, lock the valve securely.
To turn on the product, start the fan coil unit first and then start the heat
source device, e.g. chiller or boiler.
To turn off the product, stop the heat source device, e.g. chiller or boiler,
first and then stop the fan coil unit.
If the heat source device, e.g. chiller or boiler, will not be used for more
than four hours when in Cool mode, stop water circulation.
If it is impossible to stop water circulation, decrease the fan speed.
• If cold water runs when the fan of the fan coil unit is off, condensation
may occur on the fan coil unit components, such as the main unit, motor
or grille, and affect the lifespan of the product.
Do not use the product in a hot and humid location with relative humidity
over 80%.
• There is risk of fire and property loss due to water dropping from the
