2Unpacking and inspection
2.1 Inspection of equipment
Check shipping containers and contents for damage
When the system is received, please check the shipping crate and pallet for rough handling and damage. If
damage has occurred, shipping containers should be kept until the contents of the shipment have been
checked mechanically and electrically.
If the instrument is found to be faulty, please contact your local distributor. Keep the shipping material for the
carrier’s inspection and insurance claim.
Disposition of packaging materials
Rotational chair crates, equipment pallets, and other shipping materials should be recycled where available.
Contact the local distributor for on-site service of the Orion Reclining Chair, as the Orion Reclining Chair will
not normally be returned to the factory or distributor.
2.2 Removing chair from the crate
Use a power screwdriver to remove screws from top of the crate then all four sides. Unwrap chair by
carefully cutting tape and removing plastic sheeting.

Chair pallet with shipping cover removed Ramp secured to base
Chair is strapped to a 2-wheel dolly inside crate. A wooden ramp, that is part of the equipment on the pallet,
should be fastened with screws to the chair pallet to form a ramp. Tilt the chair and roll it off the pallet and
down the ramp. Position the chair in the exam room such that the cable opening in the chair base is directed
toward the equipment cart.

4 Anchoring chair to the floor
4.1 Computer setup
The chair base must be anchored to maintain proper position of the chair at the correct distance from the
wall mounted TV. The TV should be mounted on the wall before anchoring the chair to the floor.
4.2 Included parts
The Orion Reclining Chair is shipped with the following items:
1. SDS 5/8 inch masonry drill bit (hex-shank or round-shank bits can be used but are not supplied)
2. Anchor bolt kit
a. (3) 3/8 in. anchor
b. (3) 3/8 in. x 2 ¼ in. screw
c. (3) 3/8 in. ID x 2 in. OD flat black washer
d. (3) 3/8 in. ID x 1 in. OD flat steel washer
For this procedure the installer will need to use the following additional items:
1. Hammer drill
2. Hammer
3. Adjustable wrench or socket wrench
4. Ear plugs
5. Disposable dust mask
6. Safety glasses
4.3 Determine chair installation location
When locating the Orion Reclining Chair in the exam room, ensure the following items are met:
1. There will be easy access of the chair service panel.
2. The cables connect to the front of the Orion Reclining Chair. The center of this access area is the
chair zero location or Home location. This location should be aligned to the center of the television. If
the chair cannot be centered in front of the TV, then the center position will have to be set in the
software accommodate the location. Before the chair is bolted to the floor, confirm the chair will be
able to be centered in front of the television.

D-0120794-C – 2019/11
Orion Rotary Chair Installation Instructions Page 8
3. The Orion Reclining Chair should be situated away from the TV so the patient seated in the chair
(center of chair base) is between 30” and 39” (0.75 and 1.00 m) from the front panel of the TV (not
the wall). Adjacent walls should have the same clearance to the base of the Orion Reclining Chair.
4. After Chair has been carefully placed in the proper position, mark the area where the three holes are
to be drilled.
5. Move the chair to the side, or keep the chair in place and drill the holes using the base as the
template.
4.4 Drilling anchor holes
Mark drill bit with electrical tape for hole depth of 1.75 to 2 inches (4.5 to 5 cm).
Secure the drill bit in the chuck of the hammer drill. Place the drill in the middle of the target hole. Keep the
drill bit vertical. Be careful not to drill at an angle, because this may cause difficulty in keeping the anchor
screw head flush on the washer.
When drilling in concrete cement dust will be produced. The cement dust must be carefully removed from the
area after drilling. Sweep the dust and pick up remaining particles with a water dampened cloth. Do not
breath the dust, use a mouth cover as appropriate. Wear ear plugs and safety glasses while drilling into the
concrete floor and cleaning up the dust.
4.5 Variations in flooring
Carpet
If the floor is carpeted, then remove a small square of carpet that will not be visible when the chair is placed
over the hole, otherwise damage to the carpet may occur.
Ceramic Tile
If the floor is ceramic tile, then obtain a different drill bit appropriate for drilling through ceramic tile.
Vinyl Flooring
If the floor is vinyl tile over concrete, the anchor holes can be drilled with the supplied bit.
Wood Floor

D-0120794-C – 2019/11
Orion Rotary Chair Installation Instructions Page 9
If the floor is hard wood, then consult with the building owner about how they want to mount the chair.
Consider lag screws, toggle bolts or molly anchors.
4.6 Placing anchors
Place the anchor into the drilled hole with the expanded end first.
Insert the split anchor end into the drilled hole. Make sure the anchor is below the concrete surface.
Complete this process for all three anchors. Move the chair back over the anchors.
Stack the lag screw with the washers, first the small steel washer then the large black
washer. Place the screw with washers into the anchor and tighten firmly with a wrench.
The lag screw will expand the anchor in the concrete hole.
If the anchor spins in the hole, remove the anchor, clean out the concrete dust and try
again. If the anchor does not hold, contact Interacoustics or Micromedical Technologies for
further instructions.
