Please see the airflow direction label on the housing. The grilles of your ThruWall fan
may be painted to suit any decor. Thoroughly wash the grilles with mild household
detergent, dry completely, and spray with a quality, fast dry, spray paint.
STEP BY STEP INSTRUCTIONS
Step 1. Place template flush against wall. Check for level and tape in place. Note: The
wall that the template is taped to will be the fan output side.
Step 2. Cut out the opening with a small drywall saw. Take care not to damage the edge
of the drywall since you will be installing drywall anchors close to the hole to mount the
grille.
Step 3. Insert the grille with fan attached into the hole that you just cut. Make sure the fan
is level and that the grille completely covers the opening. Mark the location of the 4
mounting holes.
Step 4. Remove fan from hole and drill mounting holes with a sharp 3/16" drill bit. Insert
wall anchors in mounting holes.
Step 5. Project the edge of the round section of the cutout onto the inside of the other wall
board in three places, approximately 12" apart. Use a small square or a piece of cardboard
that has an exact 90° angle to mark the cutout points on the inside of the other wall.
Step 6. Use a small pin or very small drill bit (1/32" or smaller) to punch or drill these
three marks to the outside of the other wall.
Step 7. Place the sleeve without the grille attached, against the outside of the wall and
center its location using the three holes that you made. Then trace the outside of the
sleeve with a pencil. Cut the circular opening with a small drywall saw. Cut inside the
pencil line. Take care not to damage the edge of the drywall. You will be installing
drywall anchors close to the holes to mount the grille.
Step 8. Take the electrical box cover off of the molded on electrical box and install a 3/8"
strain relief that is appropriate for your 120VAC power supplywire and/or conduit.
Step 9. Insert your 120VAC power supply wires through the strain relief and use the
provided wire nuts to connect the white (common), black (hot), and green (ground) wires
from the TW208P ThruWall fan to the appropriate common, hot and ground wires of
your incoming power wires.
Step 10. Check to see that your strain relief is securely fastened and re-attach the
electrical box cover.
Step 11. Insert the metal sleeve with grille into the cutout opening (fan output side) and
screw the grille down snugly.
Step 12. Insert the other metal sleeve into the cutout opening (fan suction side) and snug
the flange up against the wall material.
Step 13. Position the unattached plastic grille over the metal sleeve that was just inserted
so that the logo on the center of the grille is right side up and that one of the mounting
holes is in the top center. Adjust the metal sleeve so that the three U shaped cut outs in
the flange match up with the mounting holes in the grille. Mark the location of all 3 wall
anchors.
Step 14. Drill the holes on the wall for the anchors with a sharp 3/16" drill bit. Install wall
anchors and screw the grille down snugly. DO NOT OVERTIGHTEN.
