(Optional) Welding Pipes for the Low Temperature Component
Before welding pipes, take measures to protect nearby cables and components from being burnt.
To install a low temperature component horizontally, you are recommended to place the low temperature component on one side of the outdoor unit. Figure 4-66 and Figure 4-67 show the related inlet and outlet pipe ports. Install an inverted trap respectively at the inlet and outlet pipe ports on the outdoor unit condenser, preventing refrigerant from returning.
