Indoor Installation

• Position the sections on top of one another so that

the corners are in the same plane.

• Mount the profiles supplied with AHU as described

below. For sections having equal length, these

profiles should be mounted all round the unit.

• For AHUs having shorter or longer upper sections,

no further works are required.

Check for insulation tape before section joining. In-

sulation tape shall be applied on one of the section,

Figure 20.

• If AHU has more than two sections, repeat this

procedure. For an outdoor installation of the AHU,

all external joints of the sections should be sealed.

For outdoor installation of the AHU, roof should be

applied as described in Chapter 8.
