Install Final Terminal Stopping Device at the top and bottom of the hoistway. Set as close to the terminal landings as possible without interfering with the operation of the normal terminal stopping device. Upon final adjustment and completion of acceptance test, pin final limit switch in position to prevent movement. J. Suspension Means: 1. Install hoist ropes with ends of cables fastened to car and counterweight using wedge rope sockets. Locate manufactures identification tag on car top rope termination as required by the ASME A17.1 code. K. Counterweight: Check balance relationship between car and counterweight. Add or remove filler weights and secure with rods within the frame. L. Buffers: Check alignment of buffers with respect to the strike plates on the car and counterweight frame. Install necessary blocking extensions under buffers to obtain proper clearances. M. Car Frame, Platform and Cab: 1. Ensure that running clearance does not exceed 1-1/4 inches throughout the travel of the car. 2. Ensure that there are no objectionable noises between the car enclosure and platform including frame. ____________________________________________________________________________ IBI/121539 Section 14 21 00 – Traction Elevators Page 49 of 51 3. Mount roller guides and adjust to insure continuous contact of rollers on three sides of the guide rails under all load conditions. N. Door Operator: Install door operator and integrate with elevator control equipment for required operation. 1. Adjust operator for code required closing speed and force. 2. Ensure that Code required data plate is affixed to the operator. 3. Verify infrared door reopening device is operating properly. O. Elevator Safety Equipment: Ensure that car safety devices operate freely without binding and that the proper rail clearances are maintained in accordance with ASME A17.1 code. 1. Install rope brake and hydraulic control unit (where used) in approved location. Insure that friction pads are parallel with the hoist ropes and that setting of the brake jaws is equal across the face of the ropes. Friction pads shall be "run-in" prior to acceptance test. 2. Install governor, for actuation of safety devices, in the elevator machine room on existing steel supports. P. Hall Signal Fixtures: Locate hall signal equipment for elevators as follows, unless otherwise indicated: 1. Flush mount in-car direction indicator in cab entrance jambs, minimum 72 inches above car floor in existing location. 2. Flush mount hall stations at each landing served by the elevator at 42 inches to centerline of single pushbuttons at terminal landings and to centerline between two pushbuttons at intermediate landings. 3. Flush mount combination hall lantern and position indicator over each entrance for each elevator in existing locations. Q. Lubricate operating parts of systems as recommended by manufacturers. 3.04 PAINT A. Finish ferrous metal surfaces of the elevator Work with specified paint including rust-inhibitive primer and latex acrylic enamel finish totaling not less than 2 coats thickness. Exceptions: Do not paint sliding and rubbing surfaces. 1. Low VOC, low odor, high gloss, colors as selected. 2. Paint shall be Pitt-Tech as manufactured by Pittsburgh Paints or approved equal. B. Metal Primer: VOC compliant. Low odor, fast drying, industrial grade. 1. Paint shall be Specialty Coatings Inc. "Shop Coat Primer" or approved ____________________________________________________________________________ IBI/121539 Section 14 21 00 – Traction Elevators Page 50 of 51 equal. 3.05 FIELD QUALITY CONTROL A. Demonstrate to Owner's Representative that all elevator systems and sub- systems perform in accordance with required operations B. Acceptance Testing: On completion of elevator installation and before permitting use (either temporary or permanent) of elevator, perform acceptance tests as required by the ASME A17.1 Code, in addition to the requirements of this specification, and by governing regulations and agencies. All items of this specification whether required by the ASME A17.1 Code or not, shall be tested to demonstrate proper operation. 1. Tests shall be witnessed by a Qualified Elevator Inspector (QEI) as procured by the Contractor. Testing shall include operation of the elevators on the standby power system as outlined within. 2. Contractor shall provide written documentation of test results to the Owner. Written documentation shall include reports for the following: a. Operation of the elevators on standby power. b.
