Installation & Maintenance
AXS EC
IN-LINE DUCT FANS

AXS EC in-line duct fans are not explosion proof and should not be used when
a potentially explosive situation exists. Do not use where temperatures will exceed 104 F.
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, IN URY TO PERSONS, PLEASE READ THESE
INSTRUCTIONS CAREFULLY
1. Before servicing or cleaning the unit, ensure that the electrical service to the fan is locked in
the “OFF” position 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. Do not re-establish power supply until the fan has been completely
installed.
2. Use this unit only in the manner intended by the manufacturer. If you have questions, contact
the factory.
3. A qualied person(s) must perform installation work and electrical wiring in accordance with
all applicable codes and standards, including re-rated construction codes and standards.
4. The combustion airow needed for safe operation of fuel burning equipment may be aected
by this unit’s operation. Follow the heating equipment manufacturer’s guidelines and safety
standards as published by the National Fire Protection Association (NFPA), the American
Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE), and the local
code authorities.
5. When cutting or drilling into walls or ceilings, take care not to damage electrical wires and
other hidden utilities.
6. When used to exhaust moist / humid air, fans must always be vented to the outdoors.
7. This unit may have sharp edges. Use caution to avoid injury when installing and cleaning.
8. The fan is intended to be hard wired to a properly rated electrical circuit, and must be properly
grounded. Do not use an extension cord.
1. For general ventilating use only. For use in non-re installations only. Do not use to exhaust
hazardous or explosive materials and vapors.
2. For interior use only. Mount with the lowest moving parts at least 8 feet (2.5 meters) above
the oor or grade level.
3. To avoid motor damage and noisy and/or unbalanced impeller, keep the fan clean from dry-
wall spray, construction dust, etc.
4. Before installing the unit, check for any visible damage to the impeller and housing. The
housing internals must be free of debris, which can damage the impeller blades.
5. Please read the specication label on product for further information and requirements.
6. Not for installation by any person that is unable to follow these safety guidelines.
7. To ensure optimal airflow, do not close or block the unit inlet or outlet. Do not sit or put
objects on the unit.
8. Store the fan in manufacturer’s packaging in a ventilated room at temperatures between 41 F
and 104 F. Relative humidity should not exceed 70%.

AXS EC IN-LINE DUCT FANS
AXS EC fans are made of a corrosion resistant steel housing.
Delivery set includes:
• Fan -1
• Fan bracket - 2
Depending on model, fan is compatible with 4” (100 mm), 5” (125mm), 6” (150mm), 8” (200mm),
10” (250mm), or 12” (300mm) diameter duct.
The wiring diagram for AXS EC models is shown in Figure 8. Fans are designed for continuous
operation. Protection rating from access to dangerous parts and water penetration is IPX4. Fans
can be operated at ambient temperatures between -13 F and 104 F.
For smooth airow control, it is recommended to use a speed controller. A speed controller is not
included in the delivery set and is available as an accessory.

Figure 1
Fans may be mounted in ventilation shafts either vertically or horizontally. (Figure 1) The air motion
in the system must be as shown with the pointer of the fan casing. In case of the vertical installation,
the intake spigot must be protected with a ventilation hood. To attain the best performance of
the fan and to minimize turbulence-induced air pressure losses while mounting, connect straight
air duct sections to the fan spigots. Minimum straight air duct length equal to 1 air duct diameter
on intake side and equal to 3 air duct diameters on outlet side.
TYPICAL FAN INSTALLATION
4
If the air ducts are too short or not connected
at any spigot, protect the fan inner parts
from ingress of foreign objects by installing
a protecting grille or other protecting device
with mesh width not more than ½ inch to
prevent uncontrollable access to the fans.
While installing the fan, ensure convenient
access for subsequent maintenance and repair.
The unit must be mounted on an even wall.

FAN INSTALLATION
Disconnect power supply. Install mounting brackets.
Mark fastening holes. Drill holes and insert expansion anchors.
Mount the fan. Connect air ducts. Figure 7

Disconnect and lock out power supply before performing any installation work.
Working on or near energized equipment could result in death or serious injury.
Fan installation is shown in Figures 2-7. The airflow direction should match that indicated
on the fan housing. Exhausted air must not contain any dust or other solid impurities,
sticky substances or fibrous materials.

Make sure to disconnect the fan from the power mains prior to any cleaning.
Proper maintenance (Figure 9-14) includes periodic cleaning of the fan surfaces from dirt and dust.
The impeller blades require thorough cleaning every 6 months. Remove the self-tapping screws
(Figures 11) and disconnect the grill from the casing. Wipe the fan blades with a soft cloth soaked
in a mild detergent, avoiding dripping on the electric motor. After cleaning, install the cover and
tighten screws.
