SYSTEM DESIGN CONSIDERATIONS

1.1 INTRODUCTION
The GX Pro Series Radon 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 GX Pro Series Radon Fans. These instructions should be considered supplemental to current industry standards and federal, state, county and local building codes and regulations. In the event of a conflict, those standards, codes, practices and regulations take precedence over these instructions.

1.2 FAN SEALING
The GX Pro Series Radon Fan is factory sealed; no additional caulk or other materials are required to inhibit air leakage.

1.3 ENVIRONMENTALS
The GX Pro Series Radon Fan is designed to perform year-round in all but the harshest climates without additional concern for temperature or weather. For installations in an area of severe cold weather, please contact RadonAway for assistance. When not in operation, the fan should be stored in an area where the temperature is never less than 32 degrees F or more than 100 degrees F.

1.4 ACOUSTICS
The GX Pro Series Radon Fan, when installed properly, operate with little or no noticeable noise to the building occupants. The velocity of the outgoing air should be considered in the overall system design. In some cases a “rushing” sound of the outlet air may be audible. In these instances, the use of a RadonAway Exhaust Muffler is recommended.

1.5 GROUND WATER
In the event that a temporary high water table results in water at or above slab level, water may be drawn into the riser pipes, thus blocking air flow to the GX Pro Series Radon Fan. The lack of cooling air may result in the fan cycling on and off as the internal temperature rises above the thermal cutoff. Should this condition arise, it is recommended that the fan be turned off until the water recedes, allowing for return to normal operation.

1.6 SLAB COVERAGE
The GX Pro Series Radon Fan can provide coverage up to 2000+ sq. ft. per slab penetration. This will primarily depend on the sub-slab material in any particular installation. In general, the tighter the material, the smaller the area covered per penetration. Appropriate selection of the RadonAway Radon Fan best suited for the sub-slab material can improve the slab coverage. Additional suction points can be added as required. It is recommended that a small pit (5 to 10 gallons in size) be created below the slab at each suction hole.

1.7 CONDENSATION & DRAINAGE
Condensation is formed in the piping of a mitigation system when the air in the piping is chilled below its dew point.
This can occur at points where the system piping goes through unheated space such as an attic, garage or outside.
The system design must provide a means for water to drain back to a slab hole to remove the condensation. In order to allow for proper drainage, airflow should be kept below 90 CFM when using 3” pipe. The GX Pro Series Radon Fan MUST be mounted vertically plumb and level, with the outlet pointing up for proper drainage through the fan. Avoid mounting the fan in any orientation that will allow water to accumulate inside the fan housing. The GX Pro Series Radon Fan is NOT suitable for underground burial.
For GX Pro Series Radon Fan piping, the following table provides the minimum recommended pipe diameter and

See p. 6-7 for detailed specifications.

1.8 SYSTEM MONITOR & LABEL
As may be required, system monitors, alarms and labels are available for separate purchase. The GX3 Fan is compatible with a 4.5” U-Tube Manometer (such as P/N 50017) and both of the GX3 and GX4 Fans are compatible with a 6.5” U-Tube Manometer (such as P/N 50036). You may choose to also use an audible alarm (P/N 28001-2, 28001-4, 28421 or 28535). A System Label (provided with Manometers P/N 50017 and 50036) with instructions for contacting the installing contractor for service and identifying the necessity for periodic radon tests to be conducted by the building occupants, as may be required, can be conspicuously placed in a location where the occupants frequent and can see the label.

1.9 ELECTRICAL WIRING
The GX Pro Series Radon Fan operates 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. A means, such as a weep hole, recommended to drain the box.

INSTALLATION

The GX Pro Series Radon Fan can be mounted indoors or outdoors. (It is suggested that current industry standards and federal, state, county and local building codes and regulations be followed in choosing the fan location.) The GX Pro Series Radon Fan may be mounted directly on the system piping or fastened to a supporting structure by means of an optional mounting bracket.

The ducting from the fan to the outside of the building has a strong effect on noise and fan energy use. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow.

2.1 MOUNTING
Mount the GX Pro Series Radon Fan vertically with outlet up, using flexible couplings to connect the fan to the pipe. Ensure the unit is plumb and level. When mounting directly on the system piping assure that the fan does not contact any building surface to avoid vibration noise. An optional mounting bracket (P/N 25007) is available, as are foam or rubber grommets and other items for vibration isolation.

2.2 SYSTEM PIPING
Complete piping run, as may be required by current industry standards and federal, state, county and local building codes and regulations, using flexible couplings as a means of disconnect for servicing the unit and for vibration isolation. As the fan is typically outside of the building thermal boundary and is venting to the outside, installation of insulation around the fan is not required. If desired, a vent muffler (such as P/N 24003 or 24007), available separately, may be installed at the end of the pipe.

2.3 ELECTRICAL CONNECTION
Connect wiring with wire nuts provided, observing proper connections (See Section 1.9). Note that the fan is not intended for connection to rigid metal conduit.

2.4 OPERATION CHECKS & ANNUAL SYSTEM MAINTENANCE

• Verify all connections are tight and leak-free.

• Ensure the GX Pro Series Radon Fan and all ducting are secure and vibration-free.

• Verify system vacuum pressure with manometer.
  Ensure vacuum pressure is within normal operating range and less than the maximum recommended operating pressure.
  (Based on sea-level operation, at higher altitudes reduce by about 4% per 1000 feet)
  (Further reduce Maximum Operating Pressure by 10% for High Temperature environments.)
  See Product Specifications. If this is exceeded, increase the number of suction points.

• Verify Radon levels by testing to applicable current industry standards.
