Installation Of Hydraulic Hoses From Control Cabinet To Actuator - Vexve Hydrox HCU Remote Installation, Operation And Maintenance Instructions

6.4. Installation of hydraulic hoses from control cabinet to actuator

1. Make sure that the hydraulic components have not been damaged in transport.
2. Remove the protective caps from the hydraulic connections and make sure the connections are and
will remain protected from contamination until the installation.
3. Connect the hydraulic hoses to the control cabinet connections (A and B). The hoses are connected
below the valve block. See figure 9 (cabinet overview). Hose B is connected to the front and hose A
behind it. The control system is based on the operation of A and B as follows.
a. Pressure to port A closes the actuator
b. Pressure to port B opens the actuator
4. Connect the hoses to the hydraulic actuator according to the above information.
5. Fill the system with hydraulic fluid and bleed any air. (Bleeding can be accomplished in a number of
different ways depending on the actuator, check the manual for the actuator). If the system contains
air it will not function optimally. See section 6.5.
6. Connect the position transmitter (1) signal cable to the control cabinet's appropriate outgoing
connector.
7. Test the system by operating the connected valves to fully open and fully closed, check their final
positions.
8. Check that there is no fluid leakage and all hoses are securely attached.
