Free-Field Ground Installation; Ground Installation In Front Of A Wall - MAXA i-290 0106 Installer Manual

A safety zone extending beyond the danger zone must also be identified. Within the safety zone, in the event of a refrigerant leak, the concen-
tration of the gas in the air is typically below the critical levels for the formation of flammable or hazardous atmospheres. Compliance with the
following provisions remains mandatory:
• prevent accumulation and stagnation in underground spaces, drains, manholes, cellars, etc.;
• do not place building vents inside or near the safety zone;
• do not use naked flames and other direct heat sources.
In any case, comply with national and local regulations for the installation of machinery (as applicable) in order to prevent the formation of fire
hazards and to prevent gases from seeping underground into openings to the ground or floors below.
No structural modifications may be made in the danger and safety zones that would alter their extent or change the behaviour of the air-coolant
mixture.
It is also strictly forbidden to tamper with, alter, remove or compromise, even partially, the functionality of the devices, guards and prescriptions
provided for the safety of property and persons.
In this manual, different types of outdoor installation are considered, as indicated in the following paragraphs.
