5 Steps to Installing a Bertha HV Accordion Shutter
Step 1: Laying out the shutter's components
We deliver the shutter completely ready for installation. Each shutter comes in 4 individually labeled sections (Top, Bottom, Left Stack & Right Stack. Arrange the top, bottom, left stack and right stack as shown below so that the component's backside is facing upward and the bottom (sill) is closest to the wall where the shutter will be installed.
Step 2: Building the shutter
Attach the four sections together by inserting two HV screws at each corner. You now have a "picture frame" ready for mounting
Step 3: Preparing the shutter for mounting on the wall
Stand the shutter up so that it is resting on the bottom sill. The left and right stack of blades should be fully open. This helps balance the shutters and keeps the top (currently unsupported) track from bending downward. The top track holds the entire weight of the shutter. The bottom track (sill) keeps the blades aligned with the wall, but does not support any of the shutter's weight.
Step 4: Securing the top track to the wall
Align the shutter to the corresponding opening. Our top and bottom tracks are delivered with pre-drilled holes based upon each window's requirements.
A) Start by selecting the outermost hole in top left (or right) corner. First drill a 3/16" hole then screw in a supplied 2-1/4" Maxiset Tapcon. This secures the first corner.
B) Move to the opposite top corner. Make sure that the top track is level and then drill the pilot hole in the outermost hole. Screw in another Maxiset Tapcon. The accordion shutter should now be able to support it's own weight.
C) Move to the center of the track and make sure that the track is level across its entire length. This may require that you push the track upward until everything is level. Once level, drill and insert another Maxiset Tapcon into one of the center holes. Again, check to make sure that the track is level then insert a Maxiset Tapcon into every remaining hole in the top track.
Step 5: Securing the bottom track to the wall
A) Once the top track is fully fastened to the wall, place a level on the side of the shutters and make sure that the blades are vertical. Holding the shutter in place, start by inserting a Maxiset Tapcon into one of the corner holes.
B) Move to the opposite side and insert another Maxiset Tapcon.
C) Close the shutter's blades and lock them in place.
D) Check that the blade clearance (distance from the bottom of the blade to the top of the track) is consistent across the entire bottom track. Hold the track in position and insert another Maxiset Tapcon into one of the holes in the bottom sill track. Once the bottom track is set in place, continue filling the rest of the track's empty holes with a Maxiset Tapcon.
E) Your shutter comes with two vertical locking pins (one on each center blade). These pins are normally used to hold the shutter blades in the fully open position. They can, however, also be optionally used to secure your shutters in the fully closed position or at any other partially open position along the track. Select the location(s) where you would like the pin to be used and drill a corresponding hole in the track. The pin can also be lowered in front of the lower track's front edge to lock it in the fully open position.
E) Caulking is optional, but it adds to the shutter's performance. You can add a bead of color-coordinated caulk along the vertical and top surfaces that come into contact with the wall. The top surface caulk will stop water from running down the wall and into your screw holes. The vertical side caulking does two things: 1) it stops wind and water from blowing behind the shutter and more importantly 2) it will reduce the wind pressure on your window.
