NOTICE
Do NOT install the unit tilted. Possible consequence: If the unit is tilted against the
direction of the condensate flow (the drain piping side is raised), the float switch
might malfunction and cause water to drip.
INFORMATION
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.
Installation box for the optional output PCB
An additional Installation box for the optional output PCB is required; see the
option list of the indoor unit. For installation of the installation box, refer to the
manual of the installation box. The wiring between the main PCB and the optional
output PCB must be led together with the transmission cable; never use the same
route as for the power supply cable. See
