>0.1 • Keep in mind water inlet temperature to the unit. If this temperature is below 15ºC for cooling only units (FWCK), you will need to install a water regulation pressostatic valve (as an option element) to keep condensation temperature value between 40 and 45ºC. - Page 13 • All models include three fan speed motor fan, except for FWCK/FWHK 22 models. The transmission for this model is done through pulleys and belts. • Make the motor fan connections for the fan speed required and adjust the pulley for FWCK/FWHK 22 models in order to adequate the air flow needed for the installation.
