Replace leveling air compressor

(1/2) > >>

Tom Webber:
I have a 2006 Monterey and on Monday a RV tech is going to replace the leveling compressor. I have purchased a Viair compressor to replace whatever the coach was born with. I purchased this coach used in 2016 and the existing compressor has never worked. Could someone tell me exactly was has to be done to facilitate the switch to the new compressor. Thanks in advance for the help.

Steve,

I purchased a Viair Model 380c.  Hopefully, this will work. I remember someone posted having to run a 10ga wire and installing a 30 or 40 amp relay. I can’t find that post. Would you email me (twebber93@yahoo.com) your contact information as I or the tech working on my project might want to contact you.

Tom,
Since the Viar 380 draws 23A max, it needs a 30A fuse in the supply circuit, wired with 10 awg wire.. The relay is used to turn the Viar on and off based on the PSI in the supply tank as sensed by the check valve. I've attached a diagram of the circuit. Use 10awg from the 12v house supplied 12V to the the relay and from the relay to the Viar. As noted in the thread I provided, I strongly suggest vibration dampening to reduce the compressor noise. I've also attached photos of my installed Viair and the vibration damping mount(s).

Thanks for all the help. I will keep everyone posted on the success.
