Coleman Mach Series A/C Connect by KoolRV®

Installation Instructions 

***PLEASE NOTE. YOU WILL NEED 1/2-1 INCH FOAM TAPE IF YOU HAVE A CEILING ASSEMBLY WITH THE 12X12X1 INCH RESIDENTIAL FILTER. YOU CAN PURCHASE THAT AT ANY HARDWARE STORE OR AMAZON (HERE) IT IS NOT INCLUDED WITH OUR SYSTEMS***

  1. Remove four screws holding the cover in place (be careful to hold the cover as you remove the screws to prevent breaking the cover). Set the cover to the side to be reinstalled.  (If your cover does not match this and you are not using a 12x12x1 inch residential air filter please click here for our standard Coleman Mach Series installation)

  1. Remove the filter and four screws holding the filter bracket in place. You will not be reinstalling the filter bracket. 

  1. Removing the filter bracket will expose a large open area under the A/C called the plenum. A foam divider separates the plenum into two compartments. Remove the foam divider. You may reinstall the foam divider but it is not necessary.

  1. Our system ships with the vent adapters turned 90 degrees to minimize risk of damage during shipping as well as to minimize packing space. You will need to turn the vent adapters 90 degrees. Hold the two vent adapters and press slightly toward AC adapter to keep the ducting collapsed. Turn in desired direction.
  2. Now it is time to install the A/C Connect system. Holding the system in the middle, insert the A/C adapter into the square opening in the bottom of your Coleman Mach Series A/C. The fit will be snug and should snap in to attach to the A/C. The lip of the adapter should sit flush with the metal base of your A/C. The silicone seal on the adaptor will help lock it in place, provide an airtight seal and prevent any rattling. 
  3. Next, take the two vent adapters attached to your system and insert them into the ventilation openings on either side of the plenum. The vent adapters should slide easily behind the bolts securing your A/C to your roof. If your vent openings are too small or too big all is not lost! Please visit My Vent Adapter Doesn’t Fit! for instructions on adapting our system to your rig. You may find an insert like the one in the picture below with a divider running down the center. Simply remove this insert to install our vent adapter.

  1. It’s time to test your A/C!!! Turn on your A/C and feel around the A/C Connect system. You are feeling for cold air leaks. You will feel and hear the air rushing into the A/C so don’t get confused. You are feeling for cold air specifically. If you find any leaks, simply use the foil tape to stop them. Once you have completed that, your system is fully installed!
  1. Next, take your HVAC foam tape (you can purchase here or at any hardware store) and attach it to the outside of your 12x12x1 residential air filter.
  2. Reinstall your A/C cover, filters and filter covers. Now, it’s time to enjoy your KoolRV™! 

***PLEASE NOTE. WE RECOMMEND KEEPING THE FILTER BRACKET AND FOIL DIVIDER (REMOVED DURING INSTALLATION) IN CASE YOU SHOULD EVER WANT TO REMOVE THE A/C CONNECT SYSTEM. YOUR COLEMAN MACH A/C WILL NOT FUNCTION WITHOUT EITHER THE A/C CONNECT SYSTEM INSTALLED OR THE FILTER BRACKET AND DIVIDER INSTALLED.***
