No changes permitted
No product modifications permitted.
Pre-mounting:
- Check that the threads are not damaged and are free of dirt, grease and adhesive residues.
Transmission of incorrect signals
To prevent any transmission of incorrect signals, do not change the setting of the limit switches.
To mount the product:
- Check that the mounting support is stable.
The product can be mounted in any position.
- When using a Quantum fitting, make sure not to damage the O-Ring.
- When mounting the selector valve on standard piping, use an appropriate sealant.
- Only use sealants suitable for the piping upstream and downstream of the selector valve.
- If the selector valve is mounted on the piping through its internal thread, counterhold the threaded connections of the ball valve during mounting to avoid tightening or loosening them.
- Follow the gas flow direction.
- Connect the pilot gas inlet [5] of the selector valve to the pilot circuit (L8) using the following fittings:
FIT-905 and FIT-906: G1” selector valve
FIT-903: G1 1/4", G2", G3”, and G4" selector valves - For the electrical connection of the valve and the monitoring of its position, only use resistors that are compatible with the ECP used.
The circuit diagram below illustrates the position of the limit switches and the position indicator.
Refer to the commissioning instructions for detailed assembly procedures.
