Installation Instructions
E. MECHANICAL NON-DUCTED
INSTALLATION (RARMN_ _)
1. From inside the RV, double check the gasket's
position and alignment above the roof opening.
Adjust if necessary. The air conditioner can be
moved and adjusted by pushing upwards from
inside the RV.
2. Reach through the base pan and pull the electrical
power cord from the air conditioner through the
ceiling opening.
3. Measure ceiling to roof thickness.
4. Cut rows from the bottom of the foam baffle
according to the table below:
Ceiling to roof thickness (in)
Minimum

2.5
3.5
4.5
5
5.5
Best Practice:
Cut away one row at a time and check installation
position of baffle. With the top foam compressed
onto the air conditioner's base pan, the bottom of the
baffle should be flush to the ceiling opening.
5. Install 2 baffle retainer plates onto the ceiling
assembly (Optional).
6. Place foam baffle into position between 2 retainer
plates.
7. Push the mounting template into the roof opening,
and begin hand-threading each of the 4 mounting
bolts through the nuts in the base pan.
8. Tighten the 4 bolts evenly to 35 ± 5 inch pounds
using a torque wrench at least rated for 0-60 in-lbs.
Even compression is required to prevent leaks
through the gasket.
9. Remove 6 pin connection cover from the ceiling
assembly.
