3. Installation
At the mounting and installation step, be sure all safety precautions have been considered.
Always consider how important it is the correct positioning of gas detectors to get the opti-
mum response.
ä
Be careful never to install gas detectors close to air intakes or fans causing strong air
currents.
ä
Be sure the detectors are attached to a firm base to prevent vibration that can damage
them, producing unreliable results. Although the electronics comply with the electro-
magnetic compatibility rules, it is advised to keep the detectors at a distance from any
radio frequency senders (such as radio links or similar).
ä
Please be also sure that detectors are placed in a convenient location for future main-
tenance and calibration requirements.
Refrigerant gasses emplyed in air conditioning system are heavier than air, so they tend to
spread downwards. For this reason, the detector should be placed at 30 cm from the floor.
During installation step, the user has to fix the detector with two plugs of 5 mm supplied
with the gas detector. The plugs must be positioned following the distancies described in
Figure 3.
