Grounding Instructions
ELECTRICAL:
In the USA this machine utilizes standard 15 amp
120V, 60 hz, A.C. and/or 30 or 50 amp 240V power
circuit. The amp, hertz, and voltage requirements are
listed on the data label. Using voltages above or below
those indicated on the data label will cause serious
damage.
EXTENSION CORDS:
When an extension cord is used, use UL certified
undamaged power cords appropriate to carry 120V 15
Amps or 240V 50 Amps of continuous power.
GROUNDING INSTRUCTIONS:
This machine must be grounded. If it should malfunction or break down, grounding provides a path of least
resistance for electric current to reduce the risk of
electric shock. The extension cords approved for use
with this machine have an equipment-grounding
conductor and grounding plug. The plug must be
inserted into an appropriate outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
4. Press reset button again for use.
The nominal 120-volt extension cord has a grounded
plug that looks like the plug in Figure A. A temporary
adaptor that looks like the adaptor in Figure C may be
used to connect this plug to a 2-pole receptacle as
shown in Figure B, if a properly grounded outlet is not
available. The temporary adaptor should be used only
until a properly grounded outlet Figure A can be
installed by a qualified electrician. The green colored
rigid ear, lug, or the like extending from the adaptor
must be connected to a permanent ground such as a
properly grounded outlet box cover. Whenever the
adaptor is used, it must be held in place by a metal
screw.
The nominal 240-volt extension cord has a grounded
plug that looks like the plug in Figure D. If the wall outlet
and cord in Figure E are used, be sure to plug the
attached 120V cord into the 120V grounded outlet, as
shown.
15 amp ground fault module test
instructions (manual)
Test each GFCI before each use.
1. Apply power to Crew Chief’s GFCI outlet module.
2. Press reset button on each GFCI. Each GFCI trip
3. Press test button. Each GFCI trip indicator light
indicator light should be off.
should turn on.
Figure D Figure E
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
Check with a qualified electrician or service person
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug
provided with the extension cord - if it will not fit
the outlet, have a proper outlet installed by a
qualified electrician.
Un branchement inapproprié du conducteur de
protection peut entraîner un risque d'électrocution.
Vérifier avec un électricien ou un membre qualifié
du personnel d'entretien si vous doutez de la mise
à la terre de la prise. Ne pas modifier la fiche
fournie avec la corde d'extension; si elle ne correspond pas à la prise, faire poser une fiche appropriée par un électricien qualifié.

Operations
Equipment Setup
Powering the Crew Chief
1. Place the Crew Chief in the center of a building or area to be restored. If an ungrounded 240 V supply is to be
used, locate within 10' of the grounded outlet and connect the ground jumper there.
2. Connect the Crew Chief to grounded electrical supply source(s). Use UL certified undamaged power cords
appropriate to carry 120V 15 Amps or 240V 50 Amps of continuous power. Plug in a single 240V cord and/or
multiple 120V cords.
Discharge personal static build-up by touching a face screw before touching switches or plugging in electronic cables. Otherwise component damage to switches and PCBs may occur.
Libérer l'énergie statique personnelle en touchant une vis faciale avant de toucher les commutateurs ou de
brancher les câbles électroniques. Sinon, les composants des commutateurs ou des PCB peuvent
s'endommager.
3. Select the power input 120V or 240V on the Voltage Selection Knob. All outgoing power is 120V.
4. When 240V supply is used then all the front 120V GFCI Electrical outlets are live. When 120V supply cords are
used then only the outlet immediately above the input is live.
To access environmental condition data remotely:
1. Call PROCHEM customer service @ 1-800-776-6363 to set up your Crew Chief internet account. This only
needs to be done once. Then you will have access to crewchief.prochem.com website. An account allows
uploading, storing and remote access to environmental condition data.
2. Connect Crew Chief to internet source via ethernet port on back panel.
Sensors and probes
1. Ensure that the sensors have good fully charged batteries. Sort by color and designate a room or zone for
each color of sensor.
2. Screw probes into building structure that are most suspect of being wet.
3. Plug the probes' connection cables into the sensors' cable connection ports. Every probe needs a sensor to
power it and relay data to the Crew Chief.
4. Use the Quick Start Process, turning on the sensors and setting the broadcasting channels when indicated in
the process.

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.
