Clearance Requirements

• Line voltage and low voltage electrical enclosures must have adequate clearances to meet requirements of NFPA 70

(NEC). This is typically 36" minimum. Note that additional clearance requirements may be required by local codes or
building construction specifications.

• The EZTE unit is listed by ETL (adhering to UL1996) for zero inches clearance to combustible surfaces.

• When provided with optional bottom or side casing access plate/panel, provide sufficient clearance to allow access.

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

• There are no internally replaceable components in the EZT terminal units. All controls are externally accessible.

Duct Connections and Insulation

• Provide straight duct (minimum 3 duct diameters) prior to the inlet of the terminal and 48 inches after the discharge

prior to any transition for optimum flow control. Where space is limited, these dimensions may be reduced but an
increase in minimum operating pressure and sound may occur.

• The EZTE (with integral 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.

• Outlet connection uses a standard slip/drive connection.

• 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.

• If the terminal is installed in a location with high humidity, the hot water coil (if provided) casing should be externally

insulated.

• 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.
