22.                     Procedure For One Man Pressure Relief Valve Test

At a meeting of the National Arbitration Committee held on February 8, 1984, at the Sheraton Bal Harbour, Bal Harbour, Florida, it was jointly agreed that pressure relief valve test work may be performed by one mechanic so long as the following procedure is followed:

Item 1. The elevator must be equipped with a quick release coupling to which a pressure gauge could be connected.

Item 2. The Elevator Constructor mechanic is to be supplied with a temporary run button (the cable is to be of a length which would permit the Elevator Constructor to position himself outside of the machine room or the hoistway while performing the test).

Item 3. With the elevator at the top floor, doors closed, shut off the main line disconnect.

Item 4. Disconnect one wire, which places the elevator on inspection, add one jumper on the directional limit, one jumper on the final limit, and connect the temporary run button to the appropriate terminals.

Item 5. Connect the pressure gauge to the quick release coupling.

Item 6. Put in the main line disconnect and position yourself outside of the machine room and/or hoistway and using the temporary run button, run the elevator up against the stop ring until you observe (hear) the bypass valve open.

Item 7. After checking the pressure gauge the mechanic is to open the bottom hoistway door and observe the cylinder and pipe for possible damage or leakage.

Item 8. If damage has occurred it will be repaired in the normal manner using a repair crew.

Item 9. The car will then be restored to normal service and observed as it runs the first few trips.

If there are any questions regarding this please call the hall.
