To ensure correct sealing between coil and valve make sure that the coil is fully clicked on to the valve.
Only EVUL can be applied on systems with R290 as the working uid.
For countries where safety standards are not an indispensable part of the safety system Danfoss
recommends the installer gets a third party approval of any system containing ammable refrigerant.
Note: Please follow specic selection criteria stated in the datasheet for this particular refrigerants.
