Instead, cut off it and properly wrap PVC insulation tape around the cutting place.
Installing the Indoor Unit 1. Read the related user manual or instructions before installing the NetCol5000-A. 2. The unit in this document is a fully configured NetCol5000-A. If some components are not configured, skip the corresponding steps. 3. You are recommended to use tools that are fully insulated when installing devices. 4.
