Old old question. Sometimes there is a removable plate on the back. You can run them on the outside just insert them in a larger copper tube for protection change the filter to a sporlan cap-t-032.

Hi i am, an hvac tech looking at a true gdm72f freezer cabinet when compressor comes on the voltage drops from 209 to 181 this is a brand new compressor in this unit

It sounds like a power source problem. The longer the run from the circuit breaker box, the larger the wire needs to be. The max allowable voltage drop for a 298 v circ would be 188.10
You don't have the power needed to run that pump! Sounds like a job for "sparky" ;)
