Adding Second AC to 2019 Grand Design Reflection With Coleman Mach AC Unit

Published 06/19/2020

Question:

Kyle thank you for your fast and detailed reply. I took my vent apart above the the bedroom. There is a 110V plug in the attic. My question is does the A/C unit plug in with a regular 110V plug or is there other wiring needed?

Based on my research it looks like your 29 foot, 2019 Grand Design Reflection uses a Coleman Mach Air air conditioner. You will need to verify this but if that is the case what you will need is a unit with an adapter:

- 13,500 Btu: Advent Air Replacement RV Air Conditioner for Coleman Setup with Start Capacitor # ACCOL135B (Black) or # ACCOL135 (White)

- 15,000 Btu: Advent Air Replacement RV Air Conditioner for Coleman Setup with Start Capacitor # ACCOL150B (Black) or # ACCOL150 (White)

Keep in mind the adapter wiring kit will not work on Coleman Mach 6000 or 7000 series ceiling vent assemblies, and it will not work with heat pump models.

You will not need any other wiring than what comes with the Advent Air Replacement RV Air Conditioner for Coleman Setup with Start Capacitor # ACCOL135B (Black) or # ACCOL135 (White). These will plug right in to your existing wiring with the adapter so you don't need anything extra.
