STEP 6

The interior Garnish Trim Ring must be trimmed 

to  fit  your  particular  RV  roof  thickness.      To 

accomplish  this,  measure  the  distance  from 

the vehicle ceiling surface to each corner of the 

MAXXFAN

 Control Plate.

Most  RV  roofs  have  some  slope,  so  measuring 

each  corner  is  necessary.      The  Garnish  ring 

should  be  cut  1/4”  to  1/2”  longer  than  the 

dimensions measured at each corner.

In Picture #6 to the right, the installation measures 

3  and  1/2”  from  the  ceiling  (this  is  an  example 

only) to the Control Plate.   After adding 1/2” as 

in this example, using a ruler, place a mark at 4” 

on each corner of each side of the Garnish Ring 

(refer to 6A below).   Once marked, draw a line 

connecting  all  4”  markers  on  the  outside  of  the 

Garnish ring and trim accordingly (refer to 6B to 

the right).

STEP 7

Complete the installation by placing any excess 

wiring to the inside of the roof opening and sliding 

the Garnish Ring into position.   Fasten in place by 

using the four painted flat head screws provided.

NOTE: 

DO NOT probe or tamper with the thermostat 

sensor or IR sensor shown in illustration #6 above.
