I am installing a mini-split AC system where there are multiple indoor units connected to a single outdoor unit. For each indoor unit, there is a separate 4-conductor cable that connects to the outdoor unit, and each cable is routed outside from a different location.
This is the condenser unit: https://www.supplyhouse.com/LG-LMU24CHV-20000-BTU-Multi-F-Inverter-Heat-Pump-Outdoor-Unit
This is the cable I am using to connect the indoor units to the outdoor units: https://www.genesis.resideo.com/all-products/comfort-hvac/mini-split/1070 -14/4 stranded, jacketed, rated for direct burial and sunlight resistant. Type TC-ER-JP 600V
The outside condenser unit has a hole for attaching a conduit fitting for the indoor to outdoor cabling, but there is only one hole for multiple cable, from multiple sources.
Since the cabling I am using seems like it can be used for outdoor use, do I need to run the cables through a conduit, or can they be run as is? Also, what is the best way to get multiple cables from multiple sources into the single hole in the condenser housing, and still ensure that the connection is waterproof?
