To prevent people from touching the parts inside the unit, be sure to install grilles on
the inlet and outlet ports. The grilles must be designed in such a way that cannot be
removed without tools.
Set the external static pressure between 0 to 1.2 in WG (0 to 300 Pa).
If an intake duct is installed, take care not to damage the temperature sensor (the
temperature sensor is attached to the intake port fl ange).
Install the air inlet grille for air circulation. The correct temperature can not be
detected.
A
(Room)
When connecting the duct, perform duct-insulation that is appropriate for the installing
environment.
Inappropriate insulation work may cause condensation on the surface of the insulating
material, and may lead condensation drip.
Be sure to install the air fi lter in the air inlet. If the air fi lter is not installed, the heat
exchanger may be clogged and its performance may decrease.
