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.
