Regular Checks/Maintenance
Please check the following items regularly for safety:
1. Check if there is no loose screw on the snow hood and in the joints between the snow hood and the
outdoor unit.
2. Check if there is no rust or corrosion on the snow hood and in the area where the outdoor unit is
fitted.
3. In order to prevent the snow hood from dropping, tighten screws when they are loose and make
repairs when rust or corrosion is present.
4. When oil or dust is present inside the snow hood, rust and corrosion can occur. (Mud and dust can
look like rust at times.) Clean the snow hood regularly.
