Installation
Two installs, and they are not close in effort.
Which RoadVac you have decides whether this is an afternoon with a jigsaw or a weekend with a pipe run. Neither is difficult, but it is worth knowing which one you signed up for before you cut anything.
CS-6 and CS-8
One opening, one outlet, done.
- Find a wall or cabinet face with 11 x 6 x 6 in. of clear depth behind it
- Cut the opening and check the depth before you commit
- Set the unit in and secure it — the F-70 steel bracket where the wall needs it
- Vent the exhaust overboard with the C-060-E or the AS-61 kit
- Plug in the 6 ft cord, fit a Y10 bag, test with the hose
The CS-6 is hardwired instead of corded, and adds power management for a 20-amp circuit that is already close to its limit.
CS-9, CS-10, CS-RM, CS-RM-RC
Hide the unit, put the cleaning point where the mess is.
- Mount the power unit in a basement bay, closet or cabinet
- Run 2 in. pipe or X640 flexible hose to each cleaning point
- Fit an inlet valve where you want to plug the hose in, a VacPort where you want to sweep
- Pull 22 gauge low-voltage wire alongside the pipe on automatic systems
- Vent the exhaust overboard, fit a Y11 bag, test every port
The AF-01 set at $34.43 covers a straightforward single-valve run. The A-950-X at $65.96 is the same idea with the VacPort included.

Do not skip this
Vent the exhaust outside.
The RoadVac CS line has no exhaust filter, on purpose. A coach is roughly the volume of one bedroom, and exhaust air that is filtered and returned to a room that size is still exhaust air in the room you are standing in.
The overboard option puts it outside — through the sidewall or the floor. It is the cheapest part in the whole install and the one that makes the biggest difference to how the coach feels after you vacuum it.
The door is where a coach gets dirty. It is also the best place for a VacPort.

Questions
Before you cut
How hard is a CS-8 install?
One cutout, 11 x 6 x 6 in., and a nearby outlet. The unit is self-contained so there is no pipe to run and no low-voltage wiring to pull. Most owners do it themselves in an afternoon.
What does a piped install involve?
A location for the power unit — a basement bay, a closet, a cabinet — a run of 2 in. pipe or X640 flexible hose to each cleaning point, an inlet valve where the hose will plug in and a VacPort wherever you would rather sweep than plug in, and low-voltage wire alongside the pipe if the system starts automatically.
Can I add a second cleaning point later?
On a piped system, yes — that is what the P-41 sweep tee is for. On a CS-6 or CS-8, no. Those have no pipe run to tee into.
What power does a RoadVac need?
12 amps at 60 Hz, on 110V or 220V. 240V single phase is available on request. The CS-6 adds power management, which is what makes it the right choice on a 20-amp circuit that is already loaded.
Should I vent the exhaust overboard?
In a coach, almost always. The C-060-E funnel or the AS-61 kit sends the exhaust through the sidewall or floor. It is a $12.59 to $18.86 part that stops the fine dust from coming back into a space the size of a bedroom.
Where do I find installation instructions?
