ORIENTATION Acceptable installation orientation for VM-GIB actuator.

4. Remove the Shaft adapter locking pin from the actuator and position the Shaft adapter onto the alignment mark on the actuator. Depending on the rotation to open, position the Self centering shaft adapter.

b. Counterclockwise-to-open Place the shaft adapter right next to the alignment mark keeping the mark visible

ACTUATOR ROTATION Factory setting for rotation is clockwise.

1. Determine and verify the rotation of the mixing valve. (The flat portion at the end of the shaft of the valve is an indicator reflecting the location of the internals of the valve.) a. Clockwise-to-open Place the shaft adapter right next to the alignment mark keeping the mark visible. Indicator

2. Depending on the piping arrangement and requirements, rotate the valve to a fully clockwise or counterclockwise position. 3. If the valve rotates clockwise-to-open or counterclockwise-to-open, the actuator will require proper alignment.

MOUNTING OF ACTUATOR 6. Insert the stem extender to the valve and tighten the extender with an Allen key.

10. Loosely assembly the 3/16” bolt to the mounting plate.

1) Hold down the PUSH button. 2) With an adjustable wrench grasp either the stem extender or selfcenter shaft adapter to manually rotate the valve. 3) Release the PUSH button.

7. Loosely pre-assemble the nuts for the M8 x 2.5” bolts through the Mounting Plate. 8. Align the bolts to the face plate holes on the valve body and tighten the bolts. 9.

Tighten the nuts to the Mounting Plate.

MANUAL OVERRIDE To rotate the actuator without power present, perform the following steps:

11. Slide the actuator onto the shaft and at the same time insert the 3/16” bolt head into the bottom slot of the actuator. 12. Tighten the Shaft adapter onto the extender with a 10mm or 13/32” socket and then tighten the 3/16” nut. As the shaft and nut is tightened make sure the actuator stays parallel to the faceplate of the mixing valve.

Note: If there is no load, the actuator will hold the new position. If load conditions exist, the actuator will rotate. Once power is restored, the actuator returns to automatic control. MECHANICAL RANGE ADJUSTMENT The angular rotation is adjustable between 0° and 90° at 5° intervals. With no power to the actuator, the adjustment of rotation is done by: 1) Remove the actuator from the valve. 2) Remove the shaft locking clip and adapter from the actuator. 3) Return the actuator gear train to the “0” position by following the clockwise or counterclockwise shaft rotation steps below.

9b. For 5” and 6” valve bodies use the M8 coupler and bolt (j & k) in the assembly of the Mounting Plate.

The maximum rating for a Class 2 step-down transformer is 100VA. It is recommended that no more than 10 actuators are powered by one 100VA transformer. CAUTION Do not parallel wire GIB actuators with any other type of actuator. Direction of Actuator Rotation If the actuator turns counterclockwise to open, reverse the 6 & 7 wires at the controller

4. Determine the angle of rotation for the valve’s rotation. Subtract the angle of rotation from 90°. 5. Remove the shaft adapter and insert it with the position indicator pointing to mark on the scale calculated in the previous step 6. Attach the clip. 7. Manually rotate the valve stem to its ‘0’ position 8. Return the actuator to the stem extender and tighten the shaft adapter to the extender.
