Unit Installation

Duct Connections

AllVariTrane units should be provided with a minimum of 1.5-duct diameters of straight duct prior to the inlet of the unit. It is recommended that at least 48 inches of straight duct be provided from the discharge of the units prior to any take-offs or transitions. This is a requirement for electric heat fan- powered units used in applications with 100% downward discharge.

Note: In order to maintain the UL rating forVariTrane electric coils, there must be four feet of straight unlined ductwork downstream of the reheat coil prior to any diffuser takeoffs.

After all connections are made, check that the entire ductwork system is airtight. In some high-pressure systems, duct sealer may be necessary.

Provide insulation around the entire inlet collar (all the way to the unit casing).

Use caution not to damage the flow tubes when making ductwork connections or insulating.

Cut “slits” in the insulation for the flow tubes and secure with duct tape.

If the unit is to be installed in a location with high humidity, external insulation around the heating coil should be installed as required.

Water Coil Connections

Water coil piping connections will be 3/8” or 7/8” OD.

If necessary, you can change the coil connection from left-handed to right- handed (and vice-versa) by disconnecting the coil from the unit and rotating the coil “like a steering wheel” 180°.

The inlet piping should always be connected to the bottom connection of the coil regardless of handedness.

Care should be taken to properly support the water coil piping connections while connecting the adjoining pipe.

It is recommended that piping to the water coil should be done after field- mounted controls, external insulation, and ductwork connections have been completed.

Do not connect water valve or pipe extensions to the water coil connections unless supported.

Unit Accessibility

Single-duct and dual-duct units provided with hot water reheat have an access panel located on the side of the water coil. All other single-duct and dual-duct units are provided without access, as all functioning components are external to the unit.

Fan-powered terminals are provided with a sliding side access.

Low-height terminal units have a removable bottom panel.

Clearances

For proper service, it is recommended that at least 36” of side clearance be provided to service and access single- duct and dual-duct terminals units.

Fan-poweredVAV units have a plenum inlet that must be clear of obstructions. Allow at least 36” of clearance in front of the side access and plenum opening.

Low-height fan-powered terminals require the same plenum clearance requirement that applies to the standard fan-powered units. However the access to the internal components is located on the bottom of the unit.

It is also recommended that 6” of clearance be provided to the top and bottom of all the units.

Note:The minimum clearance for controls and heater controls should be 36” for all models except units with 575- volt electric heaters, which require 48” of clearance. NEC and/or local codes override all clearance requirements.

Actuator Mounting

Trane offers a factory-mounted actuator with a 90-second drive time.The actuator drives 1 degree per second. A field-installed actuator may be used if desired.The actuator shaft has a ½-inch diameter and is designed to travel clockwise to close the damper and counter-clockwise to open the damper. There is an indicator on the end of the actuator shaft that can be used to determine the position of the damper.

CAUTION

Equipment Damage

Note:When installing or replacing the actuator tighten the actuator set screw per the manufacturer’s instructions.

Failure to follow the manufacturer’s specifications may result in unit malfunction.

VAV-SVN01E-EN, Trane specifications

The Trane VAV-SVN01E-EN is an advanced variable air volume (VAV) system designed to optimize indoor air quality and energy efficiency in commercial buildings. This system is part of Trane’s commitment to offering reliable, innovative HVAC solutions that meet the demands of modern architectural designs and energy standards.

One of the main features of the VAV-SVN01E-EN is its ability to control air flow based on occupancy and environmental conditions. This ensures that energy is used efficiently, as airflow can be adjusted to match real-time needs, rather than operating at a constant rate. The integration of intelligent sensors allows the system to adapt dynamically, leading to both reduced energy consumption and improved comfort for building occupants.

The technology behind the VAV-SVN01E-EN includes advanced digital controls and integration capabilities. These controls enable the system to communicate seamlessly with building management systems (BMS), allowing for centralized monitoring and management. This interconnected approach not only enhances operational efficiency but also enables predictive maintenance, helping facility managers identify and address potential issues before they become problematic.

Energy efficiency is further enhanced through the use of VAV technology, which reduces the amount of conditioned air delivered when spaces are unoccupied or when less cooling or heating is required. This tailored approach contributes to lower energy costs and supports sustainability initiatives by decreasing the overall carbon footprint of the building.

Key characteristics of the Trane VAV-SVN01E-EN include its compact design, which facilitates easy installation in existing spaces without significant modifications. The unit is also designed for low sound levels, ensuring that it operates quietly, contributing to a more pleasant indoor environment. Moreover, the VAV system is engineered to be reliable and durable, with rigorous testing and high-quality components ensuring long-term performance.

In summary, the Trane VAV-SVN01E-EN stands out in the field of HVAC solutions, bringing together advanced technology, energy efficiency, and user comfort. Its features are tailored for modern building requirements, making it a preferred choice for facility managers aiming to enhance indoor air quality while reducing operational costs.
