3.2.4
Chillers
Measuring leaks on outdoor chillers is generally more difficult, given the highly variable air flow.
Generally, it is recommended to install the gas detectors near the compressor, as this is the place where refrigerant leaks
are most likely to occur. In particular, check if it is possible to install the gas detector inside the closed unit near the
compressor, where gas is more likely to stagnate. However, avoid vibrating surfaces or surfaces that are difficult to access
for maintenance.
It is also recommended to install gas detectors along the ventilation system, especially in the event of low or variable air
flow speeds.
3.2.5
Air conditioning - direct VRF/VRV systems
In air-conditioned buildings, it is recommended to install at least one gas detector in each room, identifying the areas of
greatest risk, such as air flows from ventilation systems and heating systems such as radiators.
In these spaces, the refrigerant gas is usually denser than air: consequently, the gas detectors should be installed close
to the floor.
Also consider installing the gas detector in ceilings or false ceilings, if not adequately sealed. Do not install the gas
detectors underneath mirrors/washbasins and inside bathrooms.
Do not install the gas detectors near sources of steam.
3.3 Installation
Once the optimal position to install the sensor has been chosen, it is recommended to install the sensor (identifiable on
the device by the black sensor housing) in a vertical position, with the sensitive element (black part) facing downwards. The
sensor can now be mounted on the wall, as follows:
• Drill the holes in the wall using the measures on the bottom side of the detector (shown in the picture below).
•
Fix the device using four screws, chosen according to the type of installation and the type of wall, maximum diameter 4 mm,
minimum length 15 mm and torque 2,5 Nm.
• Fix the remote sensor using one screw, chosen according to the type of installation and the type of wall, maximum diameter
4 mm, minimum length 15 mm and torque 2.5 Nm.
