Calculate the service space required during the installation of the
unit, based on the following:
• If there are no walls in front of or behind the unit, a space of
500 mm is necessary in front -A- and 300 mm behind -B-.
• If the front wall is higher than 1500 mm, a space of (500 +
h2/2) mm is required at the front -A-.
• If the rear wall is higher than 500 mm, a space of (300 + h1/2)
mm is required at the back -B-.
• If a wall -D- is installed in front of the unit, a ventilation hole
-C- should be made in the wall.
• When the space over the unit is less than 1500 mm, or the
space around the unit is closed, a duct is required to prevent
short-circuits between the inlet air and the discharge air.
• If there are any obstacles in the space over the unit, the four
sides of the unit should be left open.
