Mark Equipment Anchoring Locations

Prerequisites

Overview

Procedure

  1. Lay out the two (2) pieces of the floor template (GT table: 5111499). Start with the table template, then place the gantry template over the top of the table template. Align them per the GE print.
  2. Tape the templates together, making sure that the table and gantry center lines are matched. Then tape the template to the floor.
  3. Recheck the position of the gantry in the room per the GE print. If everything matches the GE print, continue. If not, realign the templates to match the print.
  4. Make sure there are no potential clearance issues. If there are floor obstructions, such as conduits or old anchors, be sure to cut them flush to the floor to prevent the gantry from resting on them. Also, be sure there is at least 102 mm (4 in.) of clearance between any existing floor penetration and the new gantry position.
    note:

    There must be clear space without obstructions in order to:

    • Change major components, with access to the gantry tube-change (RH) side (See Figure 1).

    • Allow space for front and rear cover removal

    note:

    See Service Clearance Section found in the Pre-Installation Manual.

  5. Prior to removing this template, check floor levelness, as shown in Figure 2.
  6. Position the laser from the install kit on the template behind the table base and turn it on to project a horizontal beam across the floor template area.
  7. Measure the distance from the floor to the laser line at each bolt hole location on the template and record the measurements. Use the measurements to verify the floor is within specification. The floor must meet the minimum levelness specification: 6 mm (1/4 in.) over 3.5 m (10 ft.) between the table and gantry.

    Figure 2. Check Floor Level

    • notice
    • Positioning requires cutting eight (8) holes in the floor covering.
    • Before you drill or cut any flooring, make sure that you have discussed this issue with the customer, and that the appropriate hospital personnel have approved the location of the table/gantry.
    • Any repositioning must meet all regulatory requirements to be completed.
    • Check that the floor meets the levelness specification. Follow the escalation procedure if the floor does not meet the floor specification.
    • If the floor is not level, the system does not meet the table ISO specification. The distance from the table cradle to the floor cannot be greater than 1005 mm (40 in.).
  8. Check with the customer for approval of the gantry/table placement.

  9. Use a center punch to mark hole centers for each of the eight (8) leveling pad/anchor locations. Before moving on to the next step, see Step 11 and its note for an alternative method.
    10. Notice Image
    • caution
    • Potential for personal injury.
    • Use appropriate safety procedures when drilling the floor holes, especially if there is lead under the floor.
    • Appropriate PPE is required when working with hazardous materials.
  10. Remove the floor template.
  11. Cut tiles (or other resilient flooring) around all holes punched in the template for the gantry and table.
    note:

    A fast way to remove flooring is to use a 4 in. hole saw with a 1/4 in. masonry bit to cut through the flooring at each leveler pad location.

  12. Some sites require sealing of the floor penetrations after the flooring is removed. If this site does, use RTV or other sealant to seal the floor covering as necessary.
    13. Notice Image
    • notice
    • All documentation in this manual is based on mounting the table/gantry on a 102 mm (4 in.) concrete floor.
  13. Snap a chalk line using the marks that were made on the tape at the ends of the table template.
