Advices
Security Advice
The installation and assembly of electrical equipment may only be performed by a skilled electrician.
The products must not be used in any relation with equipment that supports, directly or indirectly, human health, life or with applications that
can result in danger for people, animals or real value.
Mounting Advices
The products are suitable to be mounted on walls or air ducts.
Each product is individually calibrated.
The product can be mounted in any position, but we recommend to install the product vertically. If this is not possible, following deviations
are expected: Cover facing upwards +20Pa; Cover facing downwards -10Pa.
Installation Notes
The product must be installed at a suitable place and within the range of validity of the local electrical installation laws and regulations.
Commissioning Notes
Check carefully that no electrical power is applied to the product before you remove the housing cover.
For the electrical connection and the selection of the set point, remove the housing cover by opening the 2 screws located on the housing cover.
Connect the electrical wire (see Terminal Connection, Page 2) accordingly. Select with the set point dial the desired switching point TOP.
Please use a solid screw driver as the set point dial is rather tight. Put the cover back on the bottom housing.
Never apply electrical power until the housing cover is securely mounted on the bottom part.
