Remove the old manifold
1. Turn OFF all power to the system.
2. Turn off all supply gases and disconnect the supply gas hoses from the console.
3. Remove the cover from the gas console.
4. Remove the connectors from the nine solenoid valves (SV2, SV3, SV4, SV6, SV8, SV9, SV10, SV11, and SV12).
They can be very difficult to remove, but do not use pliers or other tools that can pinch or damage the wires.
Two of the nine SV connectors
5. Disconnect the four hoses (blue, red, green, and black) on the open (right side) side of the enclosure.
Blue Red Green Black
Note: The hose connections use
push-to-connect fittings.
To disconnect a hose, push
the connector-collar toward
the fitting, and pull the hose
away from the fitting.
To make a connection, push
the hose into the appropriate
connector until it stops, about
12 mm (0.472 in).

Install the new manifold
NOTES:
• Always make sure the number on the valve matches the number on the connector
• Refer to the pictures shown during the removal process when installing the new manifold
1. Attach the connectors to valves SV1, SV5, and SV7 and tighten the phillips head screw to 0.7 Nm (6 in-lbs).
2. Attach the connectors to valves SV2, SV3, SV4, SV6, SV8, SV9, SV10, SV11, and SV12.
3. Attach the yellow hose and then the green hose to the front of the manifold.
4. Slide the manifold back into place and secure it to the base of the enclosure with the phillips head screw that was
removed previously.
5. Reconnect the communication cable and the valve power connector.
6. Reconnect the hoses (red, green, black, and blue). Make sure the hoses are fully seated into the valve connection.
There is a mark on the hoses that indicates when the hose is fully inserted, but it may not still be visible in the field.
The tubing is fully seated when the mark is no longer visible.
7. Reconnect the supply gas hoses and turn on the supply gases.
8. Run the gas leak tests for the system. See your HPRXD instruction manual for details.
