*1 Other temperatures upon request – check the data on the name plate.
*2 Other pressures upon request – check the data on the name plate.
*3 Pressure difference at the water connection of the dryer at maximum water flow. Other prevalences upon request.
CAUTION!
During the piping of the dryer, the inlet and outlet connections need to be supported as is shown in the
illustration.
Non-observance will cause damage.
