Determining the Installation Height

NOTE
In order to determine the installation height and throw distance, the PDS-PLUS projector bracket must be mounted to the projector. Please refer to the PDS-PLUS Installation Instructions prior to performing the following steps.

NOTE
Refer to the projectors User's Manual to determine the offset of the projector lens to the top of the screen/whiteboard.

Step 1. Measure distance from center of lens to the top of the PDS-PLUS bracket.
Step 2. Add the distance from the ground to the top of the screen (A), the recommended offset from the projector manual (B), the measurement from Step 1 (C), and then add 1.5".
(Example: A + B + C + 1.5" = ?)
Step 3. Measure the calculated distance from the top edge of the viewable area of the screen/whiteboard and mark the wall. This mark will represent the lower edge of the wall plate.

A - Distance from ground to the top of the screen/whiteboard (viewable area).
B - Manufacturers recommended offset measurement. This measurement will be listed in the Users Manual.
C - Center of the lens to the top of the PDS-PLUS bracket.
Add 1.5" to the calculated total. This total distance will be the location for the bottom rail on the wall plate.
Wood Stud Installation

Do NOT over-tighten lag bolts when attaching the mount to the wall. Improper installation may result in personal injury or damage to property.

DEAD CENTER MUST BE LOCATED ON THE STUD FOR CORRECT AND SAFE INSTALLATION.

Step 1. Use an electronic stud finder (commercially available) to locate the center of the stud that is in the wall.

Step 2. Use a pencil to mark the first mounting hole, just above your height mark (from page 4).

Step 3. Use the level to make sure the wall plate is level from top to bottom. After determining the desired viewing height, place the wall plate over the first hole and use a pencil to mark the rest of the holes.

Step 4. Once the holes have been marked, use a 1/4" drill bit and portable drill to drill the pilot holes.

Step 5. After the pilot holes have been drilled, use four (4) 5/16" x 3" lag bolts and four (4) flat washers to mount the wall plate to the wooden stud. Use a 1/2" socket and socket wrench to finish this step. Step 6. Insert and gently tap the wall plate covers into place.

Completed Installation
Solid Surface Installation

NOTE Concrete drill bits are commercially available.

Step 1. Place the wall plate against the wall and use a level to make sure the wall plate is level from top to bottom.
Step 2. Use a pencil to mark the location of the mounting holes.

Step 3. Use a 3/8" drill bit to drill the mounting holes where the marks were made with a pencil.

Step 4. Once the holes have been drilled, place the concrete wedge anchors into the hole. Using a hammer, gently tap into place.
Step 5. Once the wedge anchors have been inserted into the mounting holes, remove the nut and flat washer from the wedge anchor.

Step 6. Place the wall plate over the wedge anchors once the wedge anchors have been correctly inserted into the mounting surface.

Step 7. Place the flat washer and nut onto the wedge anchor and tighten using a socket and socket wrench. Do not overtighten.
Step 8. Insert and gently tap the wall plate covers into place.

Completed Installation
Utilizing the Storage Feature
The storage feature may be used to store electronic components. There is an accessible door on each side of the storage enclosure. It may be securely held shut with the use of four (4) M5 x 12mm security head screws. It may be easiest to pre-wire all cables down the arm (or extension) at this time (see Page 11).

Step 1. Open the storage door that is located on the side of the wall plate.
Step 2. Place the electronic components inside the storage enclosure.
Step 4. Close the storage door and secure using two (2; 1 upper and 1 lower) M5 x 12mm security head screws. Tighten using a security wrench. Repeat this process for the other side as well.
Step 3. Make all electronic connections at this time.
Attaching the Projector Arm

Step 1. Locate the mounting hook cutout on the top of the wall plate.
Step 2. Tilt the arm slightly and gently insert the mounting hooks into the mounting hook cutouts.
Step 3. Slowly lower and let the projector arm rest against the wall plate.

MAKE SURE THE PROJECTOR ARM IS FULLY SEATED BEFORE RELEASING THE UNIT.

Step 4. Locate the two (2) lock mounting points on the projector arm. These two points will be aligned with the lock mounting points on the wall plate.
Step 5. Using a security wrench, insert and tighten two (2) M5 x 12mm security head screws.

DO NOT OVERTIGHTEN THE SCREWS.
Throw Distance Calculation

NOTE
Please review the Operator's Manual that came packaged with your projector before attaching the upper mounting bracket. The correct throw distance (the distance from the projector to the screen) must be determined prior to mounting the projector.
Step 1. Refer to the projectors Users Manual to determine the distance from the lens to the front of the screen.
Step 2. Measure the distance from the front of the lens to the center of the PDS-PLUS (see diagram).
Front Mounted Lens
For front-mounted lenses, add distance (Y) to distance listed in projector Users Manual.
Rear Mounted Lens
For rear-mounted lenses, subtract distance (Y) from the distance listed.
Step 4. Use a tape measure to mark the appropriate distance on the WMK-027. This will be where the center of the mounting bracket will be located.
Calculations
X = Manufacturers recommended throw distance
Z = Distance from wall to face of whiteboard/screen
Front Lens Throw Distance = (X + Y + Z)
Rear Lens Throw Distance = (X - Y + Z)


NOTE
If installing WMK-027, please refer to Page 10 before continuing.
Upper Mounting Bracket Installation
Step 1. Insert the inner slide plate into the projector arm.
Step 2. Determine which adjustment slot will be best for the projector placement.
Step 3. Raise the upper mounting bracket into position.
Step 4. Align the mounting holes of the upper projector plate with the mounting holes of the inner slide plate.
Step 5. Secure and finger-tighten two (2) M6 x 12mm security head screws.

Step 6. Once the correct throw distance has been determined, use the security wrench (supplied) to tighten the mounting screws. Do not overtighten the screws.

Extension Arm Installation (Optional)

NOTE
Please see the Operator's Manual to determine the correct throw distance (the distance from the projector to the screen) must be determined prior to mounting the projector.

If the extension arm was purchased at a later date, the end cover must be removed prior to installing the extension arm.

Step 1. Slide the extension arm into the open end of the WMK-027 (the front of the mount).
Step 2. Attach the upper mounting bracket directly to the extension using two (2) M6 x 12mm set screws (see page 8).
Step 3. Adjust length so that the center of the upper mounting bracket matches the throw distance calibration.
Step 4. Line up the mounting holes on the extension arm with the mounting slots on the WMK-027.
Step 5. Using a screwdriver, insert and tighten two (2) M6 x 12mm security head screws, 1/4" flat washers and 1/4" nylon spacers.
Step 6. Attach the PDS-PLUS (see page 10).
Base Box Installation

Step 1. Raise the base box projector mount to the upper mounting bracket.
Step 2. Align the two (2; one each side) mounting holes.
Step 3. Using a screwdriver/security wrench, insert and tighten two (2) M6 x 12mm security head screws. Do not over tighten the screws.
Step 4. Attach the projector to the base box, referring to the PDS-PLUS Installation Instructions for final adjustments.
Cable Management

Step 1. The cable access holes are located at the end of the short throw mount and on the wall plate.
Step 2. Route the cables through one end of the WMK-027 and out the other end.
Set Screw Installation (Optional)
The M6 set screw will be used in conjunction with any standard 1-1/2" NPT or CLS (sold separately).
Step 1. Thread in CLS or any 1-1/2" NPT until securely fastened.
Step 2. Thread in one (1) M6 x 6mm set screw.
Step 3. Use an M3 security wrench to tighten the M6 set screw (included in the PDS-PLUS hardware).
