Note about Flourinated Gasses:
7. For all electrical work, fuse the specified cables. Connect cables tightly, and clamp them securely to prevent external
forces from damaging the terminal. Improper electrical connections may overheat, causing fire and/or electrical
shock.
8. All wiring must be properly arranged to ensure that the control board cover can close properly. If the
control board cover is not closed properly, it can lead to corrosion and cause the connection points on
the terminal to overheat , causing fire and/or electrical shock. If connecting power to fixed wiring, an
all-pole disconnection device which has at least 3mm clearances in all poles, and have a leakage current
that may exceed 10mA, the residual current device (RCD) having a rated residual operating current not
exceeding 30mA, and disconnection must be incorporated in the fixed wiring in accordance with the
wiring rules.
9. In certain functional environments, such as kitchens, server rooms, etc., the use of specially designed
