OCX 8800
2-2
Installation
1. Ensure all components are available to install the OCX 8800.
2. The OCX 8800 may be installed intact as it is received.
3. Weld or bolt adapter plate (Figure 2-3) onto the duct.
4. Use the pipe or wall mounting hardware as shown in Figure 2-4 to
mount a remote electronics housing. Choose a location not to exceed
the length of the electronics cable ordered.
5. Ensure the conduits drop vertically from the OCX 8800 and the conduit
is routed below the level of the conduit ports on the housing to form a
drip loop. Drip loops minimize the possibility that moisture will damage
the electronics (Figure 2-5).
6. Where a positive stack pressure exists at the installation site, connect all
pneumatic lines prior to installing the OCX 8800 in the stack or
ductwork.
NOTE
If process temperatures will exceed 392°F (200°C), use anti-seize compound
on stud threads to ease future removal of the OCX 8800.
7. Insert sample and exhaust tubes through the opening in the mounting
flange and bolt the unit to the flange.
8. If insulation is removed to access the duct for OCX 8800 mounting,
make sure to replace insulation afterward.
Do not allow the temperature of the electronics housing to exceed 185°F (85°C) or damage
to the electronics may result.
Whenever a positive stack pressure exists at the installation site, be sure to connect all
pneumatic lines prior to installing the OCX 8800 in the stack or ductwork. Failure to connect
the pneumatic lines can allow the flow of contaminants into the OCX 8800 ports.
Uninsulated stacks or ducts may cause ambient temperatures in the electronics housing to
exceed 185°F (85°C) and damage the electronics.
