Caution for welding the pipe to an outdoor unit
CAUTION
When welding the pipe, the unit may get damaged by the heat and flame from welding. Use a flame proofing
cloth to protect the unit from a welding fire or flame. Sensor for detecting outside temperature is located on the
left side of the welding part so be extra careful not to damage the sensor when welding.
The O-ring and Teflon packing inside service valve may get damaged by the heat from welding. Wrap the
bottom side of the service valve with a wet cloth and weld it as shown in the illustration. Also, water dripping
from the wet cloth may interrupt the welding. Make sure the water does not drip from the wet cloth.
Make sure that connected pipes does not interrupt each other or make contact with the product. (Vibration may
cause damage to the pipes.)
When removing the sealed pipe on the bottom side of the service valve, cut it with a pipe cutter first and then
start the welding. When the sealed pipe is welded without cutting, you may get injured by the refrigerant within
the pipe.
