SECTION 3: INSTALLATION

DANGER

Electrical Shock Hazard

Disconnect electric before service.

Controller must be properly grounded to an electrical source.

Failure to follow these instructions can result in death or electrical shock.

Installation of the ROBERTS GORDON® ULTRAVAC™ Controller and the associated external electrical wiring must be done by an electrician qualified in the installation of control systems for heating equipment.

3.1 Preparation

Before installing the controller, observe the following:

3.1.1Ensure that you have a copy of the site layout for the project that clearly identifies the separate zones.

3.1.2Familiarize yourself with the Controller and Vari- able Frequency Drive component names and loca- tions. See Page 18, Figure 7 and Page 20, Figure 8.

3.2Positioning the ROBERTS GORDON®

ULTRAVAC™ Controller and Variable Frequency Drive

3.2.1Choose a mounting location for the controller. For serviceability, it is convenient to mount the con- troller and variable frequency drive at occupant level in the vicinity of the pump. The variable frequency drive should not be more than 50' (15 m) from the pump.

Do not mount controller or VFD outdoors. VFD must not be installed where subjected to adverse conditions such as: combustible, oily, or hazard- ous vapors or dust; excessive moisture or dirt; vibration. To avoid damage from possible drips, do not mount controller or VFD directly beneath pump. Models with NEMA 4 rated enclosures will withstand exposure to dust, dirt and water.

maximum ambient temperature does not exceed 104°F (40°C). Avoid installing the VFD in mezza- nines, direct sunlight, or near external heat sources because these locations usually have unpredictable temperature rises.

Note that the maximum distance from the controller to any sensor is 300' (120 m). For longer distances, larger gauge wire may be needed (Consult your local distributor). For multiple controllers, maximum length of communication wire from the first controller to the last is 4000' (1219 m) without the use of a repeater. A repeater is available for wire length greater than 4000' (1219 m). See Page 36, Section 5.5.1. Wiring between the RS-485 converter to the controller should not be more than 400' (122 m) in length. See Page 31, Section 5.2.

3.2.2Position the controller and VFD at occupant level for ease of service. To avoid electrical interferences with communications bus, do not mount VFD directly next to controller. Allow 2'

(.6 m) minimum between controller and VFD. If the VFD is more than 100' (150 m) from the pump a load reactor (P/N 90602460) must be used.

10081601NA Rev H 12/11 specifications

Roberts Gorden is known for manufacturing high-quality heating systems, and one of their standout products is the model 10081601NA Rev H from December 2011. This unit exemplifies reliable performance and innovative technology, making it a popular choice in various industrial and commercial applications.

The Roberts Gorden 10081601NA Rev H is designed with efficiency in mind. One of its main features is the advanced infrared heating technology that ensures uniform heat distribution across large spaces. This is particularly beneficial in environments with high ceilings or open layouts, where traditional heating methods may struggle to maintain consistent temperatures. The infrared system allows for energy savings, as it heats objects and people directly rather than wasting energy on heating the air.

Another notable characteristic of the 10081601NA Rev H is its robust construction. Built to withstand rigorous operational environments, it often includes durable materials that enhance longevity and reliability. This product typically features corrosion-resistant components, making it suitable for use in various settings, including warehouses, manufacturing plants, and other commercial facilities.

The unit is also designed with user-friendly controls that allow for easy temperature adjustments and monitoring of performance. Advanced digital control systems may be integrated, providing precise control over heating levels. This feature ensures that users can tailor the heating output to their specific needs, optimizing energy consumption and comfort.

Safety is a priority with the Roberts Gorden 10081601NA Rev H, as it usually comes equipped with multiple safety features. These may include flame detection systems, automatic shutoff capabilities, and user alerts for maintenance requirements. Such features help ensure not only the efficiency of the heating system but also the safety of the personnel operating in the vicinity.

In summary, the Roberts Gorden 10081601NA Rev H is a cutting-edge heating solution that combines efficiency, durability, ease of use, and safety. Its main features, such as advanced infrared technology, robust construction, user-friendly controls, and safety mechanisms, make it an ideal choice for industries that demand reliable and effective heating solutions. Whether in a manufacturing setup or a large commercial space, this model stands out as a leading heating technology.
