2.2 Precautions on repair

1) When discharging refrigerant (from pipe or body), the discharge outlet should direct the direction where
nobody exists.
2) Do not work near fire or flame.
3) Work in a large space if possible and arrange the scaffold.
4) Especially for working on rooftop, prepare a place to keep tools and take care to prevent from falling.
5) While running (pump down work, test run), do not insert hands into fan.
6) Clean the Indoor-outdoor connecting pipes and the manifold gauge edges to be free from dust or moisture.
7) Be sure to fill refrigerant to the specified level. (If refrigerant is too much or short, the capacity is down and
trouble may occur.)
8) Keep tools well, and check the measuring machine periodically.
