NSTALLATION
When deciding the best locations for supply and return air grilles, keep in mind that cold air falls and hot air rises. Therefore, the
supply air grille should be installed high, and the return air grille should be installed low, as close to the CHEB as possible.
Tools required for this step:
•
Reciprocating saw
•
Machine screws
•
Screw & nut drivers
•
Drill
•
Hole saw 4”, 4-1/2”, 5”, 5-1/4”

The return air grille takes air from inside the cab and returns it to the air conditioner. Therefore, this grille should be placed as
close as possible to the CHEB unit. See Figure 11.
1.
Ensure that the location will have an unobstructed flow from grille to CHEB unit's evaporator coil.
2.
Use proper hole and reciprocating saws to cut minimum size hole required for your grille.
3.
Attach return air grille with four sheet metal screws. Make sure the vanes are oriented downward. See Figure 11.

antenna wires. Keep cable runs as short as possible to reduce chance of interference.
