The system can include all components or only a number of them based on the installation requirements (for example, the spacer fitting or the two 90° elbow fittings can be left out). The R473HE thermo-electric actuator can also be installed in place of the valve handwheel and it can be controlled by a chronothermostat.  Installation Example of a fan coil assembly for low wall-mounting of KFC-WD The spacer with the air vent is installed on the highest connection of the fan coil while the 90° elbow fittings are installed upstream of the valve and lockshield to shut off the system walled-in pipes. R473HE R473HE R473HE Example of a fan coil assembly for high wall-mounting of KFC-WU The spacer with the air vent is installed on the highest connection of the fan coil while the 90° elbow fittings are installed one after the other to align the valve at the same height of the lockshield and easily connect it to the system pipes. R473HE R473HE Example of a fan coil for in-floor installation of KFC-F The spacer with the air vent is installed on the highest connection of the fan coil while the 90° elbow fittings are installed one after the other to align the valve at the same height of the lockshield and easily connect it to the system pipes.
