EC6 Radon & Vapor Intrusion Fan
INSTALLATION & OPERATING INSTRUCTIONS
DO NOT CONNECT POWER SUPPLY UNTIL FAN IS COMPLETELY INSTALLED. MAKE SURE
ELECTRICAL SERVICE TO FAN IS LOCKED IN "OFF" POSITION. DISCONNECT POWER BEFORE
SERVICING FAN.
1. WARNING! For General Ventilating Use Only. Do Not Use to Exhaust Hazardous, Corrosive or
Explosive Materials, Gases or Vapors. See Vapor Intrusion Application Note #AN001 for important
information on VI Applications. See RadonAway.com/vapor-intrusion.
2. NOTE: Fan is not suitable for use with solid state speed controls. Fan has integral speed control.
3. WARNING! Check voltage at the fan to insure it corresponds with nameplate.
4. WARNING! Normal operation of this device may affect the combustion airflow needed for safe
operation of fuel burning equipment. Check for possible backdraft conditions on all combustion
devices after installation.
5. NOTICE! There are no user serviceable parts located inside the fan unit. Do NOT attempt to open.
Return unit to the factory for service.
6. WARNING! TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:
a) Use this unit only in the manner intended by the manufacturer. If you have questions, contact
the manufacturer.
b) Before servicing or cleaning unit, switch power off at service panel and lock the service
disconnecting means to prevent power from being switched on accidentally. When the service
disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag
to the service panel.
c) Installation work and electrical wiring must be done by qualified person(s) in accordance with all
applicable codes and standards, including fire rated construction.
d) Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney)
of fuel burning equipment to prevent back drafting. Follow the heating equipment manufacturers'
guidelines and safety standards such as those published by any National Fire Protection
Association, and the American Society for Heating, Refrigerating and Air Conditioning Engineers
(ASHRAE), and the local code authorities.
e) When cutting or drilling into a wall or ceiling, do not damage electrical wiring and other
hidden utilities.
f) Ducted fans must always be vented to outdoors.
g) If this unit is to be installed over a tub or shower, it must be marked as appropriate for the
application and be connected to a GFCI (Ground Fault Circuit Interrupter) protected
branch circuit.

1.0 INTRODUCTION
The EC6 Radon & Vapor Intrusion Fan is intended for use by trained, professional, certified/licensed
radon mitigators. The purpose of these instructions is to provide additional guidance for the most
effective use of an EC6 Radon & Vapor Intrusion Fan. These instructions should be considered
supplemental to EPA/radon industry standard practices, state and local building codes and regulations.
In the event of a conflict, those codes, practices and regulations take precedence over these instructions.
2.0 MOUNTING
Mount the EC6 Radon & Vapor Intrusion Fan vertically. Ensure the unit is plumb and level. When
mounting directly on the system piping assure that the fan does not contact any building surface directly
to avoid transitioning motor noise to the structure.
3.0 ELECTRICAL WIRING
The EC6 Radon & Vapor Intrusion Fan operate on standard 120V, 60Hz AC. All wiring must be
performed in accordance with National Fire Protection (NFPA) National Electrical Code, Standard #70
(current edition) for all commercial and industrial work, and state and local building codes. All wiring
must be performed by a qualified and licensed electrician. Outdoor installations require the use of a UL
Listed watertight conduit. Ensure that all exterior electrical boxes are outdoor rated and properly sealed
to prevent water penetration into the box.
3.1 ELECTRICAL CONNECTION
Connect wiring with wire nuts provided, observing proper
connections (See Figure 1. Note that the fan is not intended
for connection to rigid metal conduit. Please note that small,
capped white fan wire is not used!
3.2 SPEED CONTROLS
The EC6 Radon & Vapor Intrusion Fan is not rated for use
with separate electronic speed control. To increase fan speed
turn the speed control knob of the integrated speed control
clockwise. To reduce fan speed turn the speed control knob
counterclockwise. A small screwdriver may also be used to
turn the speed control knob. See Figure 2.
3.3 OPERATION
The EC6 should be operated within the pressure and air flow parameters shown on Figures 3, 4 and 5.
