INFO General notes:
Sensor lines, wires, etc. should not be attached with cable
binders directly to pipes or frames; otherwise, the thin pipes
may be worn through. It is better to run them through spiral
protective tubes.
If the compressor will be set up outside, UV-resistant materials
should be used.
