Standard RCU mechanical installation

Figure 3-5 shows mounting dimensions for a standard RCU. Use two #10 screws

to mount the RCU. Note that only the top left and lower right holes are used. The

ambient temperature range for the RCU is -20 ° to 70 °C. Mount the RCU as close

to the sensor as possible. Shorter calibration plumbing improves response times,

reduces calibration gas expense, and reduces the chance of contaminants in the

calibration gas plumbing.

Figure 3-5. RCU mounting dimensions - O
