1 Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.

2 Based on 75C copper wire. All wiring must conform to the National Electrical Code and all local codes.

3 These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest version), Article 310 for power conductor sizing.

Caution: When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special attention to note 8 of Table 310 regarding Ampacity Adjustment Factors when more than three (3) current carrying conductors are in a raceway.

* Top outlet supply option is available only factory installed and only on the selected models.

IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses and conductor wires in accordance with the National Electrical Code and all local codes.

Bard WA5S, WL3S, WL5S, WA3S manual Electrical Specifications, Single Circuit Multiple Circuit

WA3S, WA5S, WL5S, WL3S specifications

Bard WA5S, WL3S, WL5S, and WA3S are advanced heating, ventilation, and air conditioning (HVAC) systems designed to deliver efficient and reliable climate control solutions for various indoor environments. These models are particularly well-suited for residential and commercial applications, prioritizing energy efficiency, comfort, and user-friendly features.

One of the notable features of Bard's HVAC systems is their impeccable design, which allows for easy installation in diverse settings, including utility rooms and sidewalls. The WA series, known for its robust wall-mounted units, offers flexibility in placement while maintaining optimal airflow and temperature control. The WL series enhances this further with a high-efficiency heat pump option, providing both heating and cooling capabilities in a single unit, thereby streamlining operations and reducing energy costs.

Energy efficiency is a hallmark of Bard's technology. These models typically come equipped with high Seasonal Energy Efficiency Ratios (SEER) and Heating Seasonal Performance Factors (HSPF). This means they consume less electric energy while providing superior heating and cooling performance, contributing to lower utility bills and a reduced carbon footprint. The innovative design also reduces noise levels during operation, creating a more pleasant indoor environment.

Another significant aspect of the Bard WA and WL series is their durable construction. Built to withstand various climatic conditions, these HVAC systems use high-quality materials that ensure longevity and reliability. The units feature corrosion-resistant finishes and sturdy components capable of withstanding harsh indoor and outdoor environments.

Incorporated smart technologies provide added convenience. Many of these models support programmable thermostats and zoning systems, allowing users to customize their comfort levels according to individual preferences. This not only promotes comfort but also enhances energy savings, as heating and cooling can be adjusted based on occupancy and usage patterns.

Furthermore, Bard's commitment to easy maintenance is evident in the design of these units. Access panels are strategically placed to simplify service requirements, while filter maintenance is straightforward, ensuring optimal performance and longevity.

Overall, Bard WA5S, WL3S, WL5S, and WA3S systems stand out in the HVAC market for their combination of energy efficiency, flexibility, durability, and user-friendly features, making them a compelling choice for those looking to enhance their indoor climate control solutions.
