(5) Slope of twinning pipes (high-pressure side only)
Make sure the slope of the twinning pipes are at an angle
within ±15˚ to the horizontal plane.
If the slope exceeds the specified angle, the unit may be
damaged.
Note. Refer to the figure below for the installation position of the twinning pipe.
· Before heating the pipes, place a wet towel on the refrigerant service
valve to keep its temperature below 120
˚C [248˚F]
.
· Direct the flame away from the cables and sheet metals inside the unit
so as not to burn them.
