Menu Navigation
The top row of the display provides information like where the operator is in menu structure, or sensor data. The
bottom row of the display provides information and navigation and control options. Below the display are three
buttons used to navigate through the Crew Chiefs menu structure, corresponding to the bottom row of text. The
chevrons on the left and right of the display indicate multiple menu options at that level. Continuing to press either
the left or right button will scroll through those options, returning to the original page. Pressing both the left and right
buttons will navigate up to the Main Menu Run page.
Crew Chief Setup
1. Complete the Quick Start Process.
2. The time and date are set automatically when connected to the internet. No Prochem web account is required
for this feature. The time will be set to UTC.
3. Read the Crew Chief's status/sensor readings to verify that all sensors and probes are functioning correctly
and to effectively distribute fans, dehumidifiers and other equipment. (Refer to the Sensor Data Menu)
Auxiliary Equipment
1. Place the fans as appropriate in each of the regions or rooms. Plug the fans so that they get their power from
the controlled outlets on the Crew Chief.
NOTE: Fans increase air flow past damp areas, causing the air to draw away more moisture. This raises the
humidity levels so that dehumidifiers are more effective. Multiple fans can raise the humidity faster than a
dehumidifier can remove the water from the air. If the humidity gets too high, water will start to precipitate out,
starting on cool surfaces. This can cause secondary damage to a remediation site. To avoid this the Crew Chief
has the optional Auto Fan Control. This will turn off the outlets that are controlled by sensors that are reading
excessive moisture levels. Plug fans into the Red, Green, or Blue power outlets and place fans and color
matching sensors in the same zone of the remediation site.
2. Dehumidifiers and other equipment need to be powered from the live uncontrolled electrical outlets. When the
dew point in a room is reached the sensors will indicate it and the Crew Chief will temporarily turn off the
controlled outlets until the Dehumidifiers lower the ambient air humidity.
Verify that the Quick Start Process is completed.
3. Turn on equipment sequentially checking current amperage readings on the Crew Chief to guarantee safe
uninterrupted working levels. (Refer to the Current Status Menu)
4. Use good cord management practices to remove tripping hazards.
5. Run ducting to/from fans as required.
