• Make sure that EEV-KIT should be installed within 5m from the heat exchanger.
• Make sure that filter and valve body should be kept under 120˚C with wet cloth.
• Make sure that pipes are fully insulated. If there is any uninsulated part, it may cause condensation dripping.
• EEV-KIT should be installed in the vertical direction within the range of ± 15˚.
If it is tilted over than 15˚, it can badly affect normal operation of EEV.
