2. 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.

3. NOTICE! There are no user serviceable parts located inside the fan unit or power supply. Do NOT attempt to open. Return unit to the factory. (See Warranty, p. 7, for details.)

4. WARNING! Do not leave fan unit installed on system piping without electrical power for more than 48 hours. Fan failure could result from this non-operational storage.

5. 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. (See p. 7.)
   b) Before servicing or cleaning unit, unplug power supply fron wall receptacle to prevent power from being switched on accidentally.
   c) Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. 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.
   d) When cutting or drilling into a wall or ceiling, do not damage electrical wiring and other hidden utilities.
   e) Ducted fans must always be vented to outdoors.
   f) 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.

NOTE: Verify voltage at wall receptacle is within range of 120V.

SYSTEM DESIGN CONSIDERATIONS

1.1 INTRODUCTION
The LV175 Pro Series 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 LV175. 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.
1.2 FAN SEALING
The LV175 Pro Series Fan is factory sealed; no additional caulk or other materials are required to inhibit air leakage.
1.3 ENVIRONMENTALS
The LV175 Pro Series 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 LV175 Pro Series Fan, when installed properly, operates 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 the “rushing” sound of the outlet air may be disturbing. In these instances, the use of a RadonAway Exhaust Muffler is recommended.
(To ensure quiet operation of inline and remote fans, each fan shall be installed using sound attenuation techniques appropriate for the installation. For bathroom and general ventilation applications, at least 8 feet of insulated flexible duct shall be installed between the exhaust or supply grille(s) and the fan(s). LV175 Pro Series Fans are not suitable for kitchen range hood remote ventilation applications.)
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 LV175 Pro Series Fan. The lack of cooling air may result in the fan cycling on and off as the internal temperature rises above the thermal cutoff of the motor. 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 LV175 Pro Series 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. 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. The LV175 Pro Series 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 LV175 Pro Series Fan is NOT suitable for underground burial.
For LV175 Pro Series Fan piping, the following table provides the minimum recommended pipe diameter and pitch under several system conditions.

See p. 7 for detailed specifications.

1.8 SYSTEM MONITOR & LABEL
A System Monitor, such as a manometer (P/N 50017) or audible alarm (P/N 28001-2, 28001-4 or 28421), is required to notify the occupants of a fan system malfunction. A System Label (provided with Manometer P/N 50017) with instructions for contacting the installing contractor for service and identifying the necessity for regular radon tests to be conducted by the building occupants must be conspicuously placed in a location where the occupants frequent and can see the label.

INSTALLATION

The LV175 Pro Series Fan can be mounted indoors or outdoors. (It is suggested that EPA and radon mitigation standards recommendations be followed in choosing the fan location.) The LV175 Pro Series Fan may be mounted directly on the system piping or fastened to a supporting structure by means of an optional mounting bracket. Do not install/mount the power supply outdoors.

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 LV175 Pro Series Fan vertically with outlet up. Insure 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.
2.2 MOUNTING BRACKET (optional)
The LV175 Pro Series Fan may be optionally secured with the RadonAway P/N 25007 mounting bracket. Foam or rubber grommets may also be used between the bracket and mounting surface for vibration isolation.
2.3 SYSTEM PIPING
Complete piping run, 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.
2.4 ELECTRICAL CONNECTION
Fan comes with an integral low voltage power supply that converts 120 volts AC voltage to 24 volts DC. Each end of the power supply has a distinct plug:
a common male two-prong for the AC side and a weathertight, locking two-pin connector for the DC voltage. Do not install/mount the power supply outdoors. To connect the power supply for operation, simply align the two pins of the 24-volt DC plug with the mating connector on the fan, paying attention to the alignment key inside the connector. Push the connector and plug fully together until they seat, and then twist the locking collar ring until finger tight. Plug the 120-volt AC end into a standard household wall outlet and the fan is now operational.

2.6 OPERATION CHECKS & ANNUAL SYSTEM MAINTENANCE

• Verify all connections are tight and leak-free.
• Ensure the LV175 Pro Series Fan and all ducting are secure and vibration-free.
• Verify system vacuum pressure by viewing 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 EPA Protocol and applicable testing standards.
