3. Set UT - Turn the up transition adjuster slightly, in or out, to bring the car to stabilized leveling speed at a
distance 4" - 6" below the floor level.
4. Set UL - Disconnect the U Coil, turn the UL adjuster in (CW) to a stop. Place call, the car should move upwards
about 3-5 feet per minute. (If not, set the LS adjustor.) Set the elevator to 5 – 6 feet per minute by turning UL OUT
(CCW). Later, with valve units combined the elevator should reach a leveling speed of 10 - 12 feet per minute.
5. Set US - Turn the US (Up Stop) adjuster to the full out (CCW) position. The elevator should stop about 1/8" to 3/8"
below floor level at each floor with all US adjusters in the full out position. Turn in the US adjuster on one designated
valve to bring the car up to the exact floor level. (Each pump motor should be timed to run ½ second after the car
has come to a stop at the floor level.)
6. Set Relief - Land car in pit and install pressure gauge in A port. Then register an up call with a fully loaded car,
making note of Maximum operating pressure. Turn UA and RELIEF adjuster OUT (CCW) to stop. Close the manual
shut off valve to the jack. Register an up call, observe pressure gauge and turn RELIEF IN (CW) to increase
pressure. Final setting should be in accordance with local code requirement not to exceed 150% of maximum
operating pressure. Tighten the lock nut (snug). Restart to check the pressure relief setting. Seal as required. Open
the manual shut off valve to the jack. Readjust UA for proper Up Acceleration.
DOWN Section Adjustment - Start and adjust each valve unit separately. Later, combine the valve units and make
final adjustments as indicated.
1. Set the Down Speed (D) - The down speed for an individual unit is obtained by dividing the contract speed by the
number of down valves used. Add 10 % for UC-2 and UC-2A valve down speed setting.
2. Set Down Leveling Speed (DL) - Set DL to 3-5 foot per minute on each valve, or set DL on one designated valve for a
down leveling speed of 6 - 10 feet per minute.
3. Set Down Transition (DT) so that the car slows to stabilized leveling speed about 4 - 6 inches above the floor.
4. Set the down acceleration (DA) so that the car comes up to speed within 24 - 36 inches of down motion. When the
valve units are combined the combined acceleration may need to be softened. If so, adjust each valve DA setting
incrementally the same amount.
5. Down Stop (DS) - If a more solid down stop is required, open DS as required. When valves are combined, if
adjustment is needed, adjust DS incrementally in or out the same on each valve.
Adjustment ( Valve # 2 )
Reconnect pump # 2 and open shut off valve # 2. Electrically disconnect pump # 1 and close shut off valve # 1
1. Perform all previous steps on valve # 2.
Some fine adjustment maybe needed once both systems are reconnected and the independent adjustments are
complete. After adjustments of valve # 1 and # 2 are finished, combine the pump and valve units and make final
adjustments as indicated.
