Parts for Sunset Neb100 Compressor

Hello, I like to appreciate your team's prompt service and helping us out with this as hospice was retracting their unit. Your service is very much appreciated. However the unit itself has been a disappointment. The unit upon opening smelled very heavy petroleum like aroma. Can not use as is for my mother. Now we are without a unit since just yesterday they took the other Sunset unit. Also the old unit would generate vapor but cool this unit generates very warm vapor. Is something wrong with this unit? Is there other Sunset or equal brand without these issues for us to exchange. We only took out of box and turned on once just to check. Wveythng else still in original packaging. Please advise, she needs a unit fast. Thank you
