• Unit specific nameplate showing model number, serial number, manufactured date, and information regarding controls and heat provided as appropriate.

• The appropriate airflow calibration chart indicating the airflow at varying airflow sensor signals as shown on pages 16 and 17.

• The appropriate wiring/piping diagram for controls provided by Anemostat, as well as directions for field adjusting the minimum and maximum airflow settings.

• Up arrow indicating the proper orientation of the unit for installation.

• Airflow direction arrow indicating the proper orientation of the duct connections.

• ARI logo indicating the units performance is ARI certified.

• Sheet Metal Workers Union logo indicating unit produced by members of The Sheet Metal Workers Union.

The unit also is shipped with a protective tape over the inlet collar. This tape must be removed prior to connecting the duct work to the inlet collar.

Receiving and Inspection Instructions

• Check the bill of lading to verify receipt of all listed items (including any loose accessory items). Notify the carrier and the local ANEMOSTAT representative of any shortages or items shipped in error.

• Thoroughly examine all units for transportation damage (dents, punctures, etc). If damage is found, immediately notify and file a claim with the carrier. Note details of any damage on the bill of lading before signing for the shipment.

• Each terminal has a nameplate indicating the model number. When requested, the unit may also be mark with jobspecific information (tagging). Locate the nameplate and verify that the correct units with options (controls, heating coils, etc) where received as ordered.

• Store units in a secure, dry location in the original packing, and do not stack any higher than as shipped.

Warning – Electrical Shock, Burn, and other Hazards

• Heating elements must be disconnected, or water coils allowed to cool prior to servicing. Electric heaters may start automatically, or water valves may open intermittently. It is essential to disconnect all power and control circuits prior to servicing to avoid burning hazards.

• All fastening straps or hangers must mechanically lock the terminal in place and withstand typical vibration and/or disturbances during use.

• Use caution during rigging such that all equipment remains adequately secured until it is affixed and secured in its final location.

• All supports must be designed to meet applicable local codes and ordinances. Before rigging and installation, check equipment weights such to ensure temporary and permanent supports are safely maintained.

• Make certain all power sources are disconnected prior to installation or servicing this equipment. Make certain if there are multiple power connections, that all are securely disconnected to avoid electrocution or shock injuries.

• Disconnect control circuits or pneumatic control systems to avoid injury when working on dampers or actuators, which may respond automatically to a remote control source.

• Guard against flame hazards when soldering or brazing water coil connections to avoid personal injury or property damage. Prior to using any open flame, keep a fire extinguisher nearby.

• All insulated units (except closed-cell) contain fiberglass wool. Disturbing the insulation could expose the installer to airborne particles of glass wool fibers and ceramic fibers. Certain jurisdictions feel that exposure to these fibers through inhalation can cause cancer. Glass wool fibers may also cause respiratory, skin or eye irritation.

Terminal Installation

To ensure proper operation of the Fan Terminal, the following installation procedures must be implemented.

1. UL1995 dictates that the unit must be installed at least eight feet above floor level.

2. Install terminal to allow for straight upstream duct connection to the inlet for optimum flow uniformity, if possible.

3. Extreme care must be used when lifting the unit. Do not use the air flow measuring tubes for lifting the unit! This

could result in damage to the unit and incorrect flow measurements.

4. The unit must be installed horizontally (the labels will be easily read). With reference to the primary air supply inlet, the fan and primary control enclosure will be on the left side. The motor access door will be on the bottom, where 7 inches of vertical clearance are required to remove the door. The unit may be suspended by four 5/16 hanger rods that are secured through 3/8 diameter hole in the four (optional) hanger brackets. Optional mounting brackets are field installed and should be located as indicated in drawings on page 9 thru 14.

5. Care must be taken so as not to crimp the inlet or discharge duct connections.

6. Proper clearance at the bottom is required for removal and service of the fan terminal components. (see note 4 above) Refer to the following dimensions for each unit size and type to verify adequate spacings.

7. Make certain not to obstruct service access to any electrical enclosures or access panels for access to the interior of the unit.

Clearance Requirements

• Line voltage and low voltage electrical enclosures must have adequate (minimum 36") clearances to meet requirements of NFPA 70 (NEC). Note that additional clearance requirements may be required by local codes or building construction specifications.

• The motor access door will be on the bottom, where 7 inches of vertical clearance are required to remove the door.

• Unit should hang freely, and not make contact with any structure above.

Duct Connections and Insulation

The terminal should be installed in a location that offers straight duct upstream of the unit, for best performance.

• Remove the protective tape covering the inlet collar prior to connecting the ductwork.

• Provide at least 48 inches after the discharge prior to any transition for optimum flow control.

• Units (with electric heat) MUST be installed such that a minimum of 48 inches of full-size, straight duct is connected before any elbows, filters, transitions or any other downstream air disturbance.

• Connecting duct should be configured and installed in accordance with SMACNA guidelines and local code requirements.

• Inlet duct should be the same size as unit inlet. Straight, solid (non-flexible) duct will yield the best airflow and acoustical performance.

• Slide duct over inlet collar, fasten and seal in accordance with the project plans. Provide insulation over the entire inlet collar, while allowing clearance for the flow sensor tubing.

• After all duct connections are made, check that the entire ductwork system is airtight.

Hot Water Connections (when applicable)

• Hot water heating coils require a field sweat connection to control valve(s) and water supply. Refer to unit construction submittal drawing for specific connection size. Use appropriate brazing alloy for connection.

• The hot water coil is provided in either a right or left hand connection configuration. If necessary, the coil can be rotated 180 degrees for the opposite hand connection.

• Inlet water temperature should not exceed 200°F per UL 1995.

Electrical Connections

NOTE: The manual was written with the understanding that the line power and control wiring drawings submitted for

the specific project have been acquired and are available during installation.

• Electrical wiring, connections, fusing and installation must conform to the local building codes and the NATIONAL ELECTRIC CODE.

• For terminal with electric heat, check the unit wiring diagram for single or dual point connection for electric heater and fan motor voltage.

• The fan terminal I.D. label lists Maximum Overcurrent Protection (MOP) for single point connection fan terminals that have loads consisting of both blower motor and electric heater. This is considered a motor group installation. For these units, the supply circuit must be fused individually.

• UL standards dictate that the power source must be within 10% of nameplate voltage, for safety and longevity. If incoming voltage is 10% above or below nameplate voltage, contact power Company to correct before operating terminal.

• The supply circuit can be fused external to the unit by the installer. The electric heater may be specified with primary circuit fusing which would not require external fusing.

• If the blower motor is the only load, the MOP value on the fan terminal label is blank. In this case, the units may be field wired for multiple hookups from a single branch circuit, as specified by the National Electric Code/Canadian Electric Code and Local Codes.

• Only special HACR-type circuit breakers may be used in place of fusing for over current protection of motor group installations.

• To determine the minimum wire size for terminals without electric heat, use the motor amperage listed on the fan terminal label. The label lists the Minimum Circuit Ampacity (MCA) to determine the proper size for units with electric heat. The power supply wiring is to be sized in accordance with the National Electric Code/Canadian Electric Code and Local Codes.

• The power supply terminal block is for use with copper conductors only.

• Field installed electrical components must be mounted and wired per factory supplied wiring diagram. Factory wiring must not be altered without written approval from ANEMOSTAT; violation of this will void warranty.

For fan terminals provided with electric heating coil: note these additional instructions:

• Connect the fan terminal as shown on the heater wiring schematic diagram found inside the heater wiring enclosure, and also per interlocking VAV controls where applicable.

• The minimum airflow allowed is 70 CFM per KW of electric heat.

• 480 volt/3 phase coils may incorporate "wye" or other unbalanced configuration for multiple steps.
