Notes: 1. Height of walls in case of pattern1:
Front side:1500mm, Suction side:500mm
2. If the above wall heights are exceeded, then h1/2 and h2/2 should be added to the front and
suction side service spaces respectively as shown in the following figure.
3. When installing the units, the most appropriate pattern should be selected from those shown.
In order to obtain the best fit in the space available, always bear in mind the need to leave enough room for a person to pass between units and wall and for the air to circulate freely. Your layout should take into account the possibility of short circuits.
4. The Units should be installed to leave sufficient space in front for the on site refrigerant piping
work to be carried out comfortably.
