Optional equipment. When installing optional equipment, also read the installation
manual of the optional equipment. Depending on the field conditions, it might be
easier to install the optional equipment first.
▪ In case of installation with a fresh air intake kit. Install the fresh air intake kit
always before installing the unit.
