Notice:
HRCK, HRCP, HRCL & HRCD Series actuators are fully assembled, calibrated and tested prior to
leaving our factory. In most cases, after you have mounted the actuator to your device, you should be able to
operate the actuator from fully CLOSED (CW) to fully OPEN (CCW) and back again, and find that no adjustments
are needed. The assembly can be put into service immediately.
If, however, it should be necessary to make adjustments to the end-of-travel positions to overcome any device
related issues (i.e. valve shaft incorrectly timed to the drive stem), the procedures outlined in the Installation,
Operation and Maintenance Instructions (IOM) for each unit should be followed to put the assembly into
service. Note that there is a maximum adjustment range of +/- 3° at each end of travel.
CAUTION –
For any 3 Phase products (i.e. HRCK4AR8), refer to the IOM for the respective 3 Phase unit.
These instructions are specific to low voltage and single phase products only.
