3.3.3 General installation instructions
Pay attention to the following points during installation:
 Due to its weight, the Alyza IQ always has to be carried by two people (hous-
ing door upward, both people grasping the housing at the upper C rail and at
the housing bottom on the side of the door).
 Wear safety shoes for transport, installation and mounting work (see
section 2.4 Personal protective equipment (PPE),
 24).
 Installation in the open should be done while the weather is frost-free
(environmental conditions, see section 3.3.1 Requirements of the measure-
ment location,
 26).
 Mount the Alyza IQ as straight as possible to ensure that the liquids can drain
off optimally.
 Mount the Alyza IQ so that the space under the housing bottom is always free
for ventilation of the housing.
 Mount the Alyza IQ at a suitable height so that the liquids in the return lines
(into the basin) can freely drain off at a steady slope.
 The Alyza IQ may only be fastened on a wall or fixture with the aid of the two
C-rails (housing upright).
 For mounting work, only use the mounting accessories included in the scope
