4. If the unit goes back into “run” mode, the leak is within the
cabinet. Check all the lines going to the blender and back to the
tank.
To find the leak within the cabinet:
1. Open the front cabinet door and locate the N2 storage tank.
2. Close off the output ball valve from the tank (upper ball valve on
the red manifold).
3. Watch the exterior gauge above the cabinet for 60 seconds. If you
see the pressure dropping, the leak is somewhere between the
output ports, to the blender (if one is present), and back to the
closed off ball valve on the tank. Fill and/or listen for leaks and
fix them once found. If the pressure is not dropping go to the next
step.
4. With the unit still running, close off the input ball valve to the tank
(lower ball valve on the red manifold).
5. Within 5 minutes, the system should go into “Standby” Mode. If
it doesn’t, contact your local provider/installer for further
assistance.
6. Once in “Standby” mode, wait 60 seconds. After 60 seconds, the
system should remain in “standby” mode. If it doesn’t, the leak is
somewhere between the check valve and the output ball valve on
the tank.
7. If the system remains in standby, contact your local
provider/installer for further assistance.
