Dometic FreshJet 5 Ceiling Assembly for Non-Ducted Installations with Wall Thermostat

What is included in the Dometic FreshJet 5 ceiling assembly for non-ducted installations with wall thermostat?

This collection covers the ceiling assembly components needed for a non-ducted FreshJet 5 install paired with a wall-mounted thermostat instead of a unit-mounted control. That includes the interior ceiling plenum, return air grille, and the mounting hardware that secures the assembly to the roof opening. Verify your FreshJet 5 model number on the rooftop unit data plate before ordering to confirm the correct ceiling assembly variant.

Can I use this ceiling assembly for a brand new installation?

Yes. This assembly works for a brand new FreshJet 5 install on a non-ducted RV roof opening (standard 14 x 14 inch vent cutout) when you are running a wall thermostat rather than a ceiling-mounted control. You will still need the rooftop FreshJet 5 AC unit and a compatible Dometic wall thermostat to complete the system. For ducted configurations, see the Coleman Power Saver HP ceiling assembly for ducted installations.

Are mounting brackets included with the ceiling assembly?

The ceiling assembly ships with the standard mounting hardware required to clamp the interior plenum to the rooftop unit through a 14 x 14 inch opening, including the roof compression gasket and bolt set. If you are replacing only the rooftop unit and keeping your existing interior assembly, review the Dometic ceiling assembly for non-ducted installations with wall thermostat for individual replacement components.

What is the difference between this assembly and the heat pump version?

This assembly is built for the cool-only FreshJet 5 rooftop unit with wall thermostat control. If your rooftop unit is the heat pump variant, the wiring and thermostat compatibility differ, and you will want the FreshJet 5 with heat pump ceiling assembly for non-ducted installations instead. Confirm cool-only versus heat pump on your unit's data plate before ordering.

Do I need a wall thermostat to use this ceiling assembly?

Yes. This non-ducted assembly is configured for systems controlled by a Dometic wall thermostat, so the interior plenum does not include an onboard control panel. The thermostat is sold separately. If your installation calls for unit-mounted controls instead, that requires a different ceiling assembly variant, call or text 817-984-1852 and we will confirm the correct part for your FreshJet 5.
