Shipping Damage, General, Duct Work, Filters

SHIPPING DAMAGE

Upon receipt of equipment, the carton should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier’s agent.

GENERAL

The equipment covered in this manual is to be installed by trained, experienced service and installation technicians.

The refrigerant system is completely assembled and charged. All internal wiring is complete.

The unit is designed for use with or without duct work. Flanges are provided for attaching the supply and return ducts.

These instructions explain the recommended method to install the air cooled self-contained unit and the electrical wiring connections to the unit.

These instructions and any instructions packaged with any separate equipment required to make up the entire air conditioning system should be carefully read before beginning the installation. Note particularly “Starting Procedure” and any tags and/or labels attached to the equipment.

While these instructions are intended as a general recommended guide, they do not supersede any national and/or local codes in any way. Authorities having jurisdiction should be consulted before the installation is made. See Page 1 for information on codes and standards.

Size of unit for a proposed installation should be based on heat loss calculation made according to methods of Air Conditioning Contractors of America (ACCA). The air duct should be installed in accordance with the Standards of the National Fire Protection Association for the Installation of Air Conditioning and Ventilating Systems of Other Than Residence Type, NFPA No. 90A, and Residence Type Warm Air Heating and Air Conditioning Systems, NFPA No. 90B. Where local regulations are at a variance with instructions, installer should adhere to local codes.

DUCT WORK

All duct work, supply and return, must be properly sized for the design air flow requirement of the equipment. Air Conditioning Contractors of America (ACCA) is an excellent guide to proper sizing. All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conserve energy and prevent condensation or moisture damage.

Refer to Table 10 for maximum static pressure available for duct design.

Design the duct work according to methods given by the Air Conditioning Contractors of America (ACCA). When duct runs through unheated spaces, it should be insulated with a minimum of 1 inch of insulation. Use insulation with a vapor barrier on the outside of the insulation. Flexible joints should be used to connect the duct work to the equipment in order to keep the noise transmission to a minimum.

A 1/4 inch clearance to combustible material for the first 3 feet of duct attached to the outlet air frame is required. See Wall Mounting Instructions and Figures 3 and 4 for further details.

Ducts through the walls must be insulated and all joints taped or sealed to prevent air or moisture entering the wall cavity.

CAUTION

Some installations may not require any return air duct. A metallic return air grille is required with installations not requiring a return air duct. The spacing between louvers on the grille shall not be larger than 5/8 inches.

Any grille that meets the 5/8 inch louver criteria may be used. It is recommended that Bard Return Air Grille Kit RG-2 through RG-5 or RFG-2 through RFG-5 be installed when no return duct is used. Contact distributor or factory for ordering information. If using a return air filter grille, filters must be of sufficient size to allow a maximum velocity of 400 fpm.

FILTERS

A 1 inch throw away filter is suppled with each unit. The filter slides into position making it easy to service. This filter can be serviced from the outside by removing the service door. A 1 inch washable filter and a 2 inch pleated filter are also available as optional accessories. The internal filter brackets are adjustable to accommodate the 2 inch filter by loosening 2 screws in each bracket assembly and sliding the brackets apart to the required width and retightening the 4 screws.

WA301, WA361 specifications

The Bard WA361 and WA301 are two advanced wall-mounted air conditioning systems designed for commercial and residential use. These units are engineered to provide efficient cooling and heating while optimizing energy consumption.

One of the standout features of the Bard WA361 and WA301 models is their compact design. This allows for easy installation in various spaces where traditional floor-mounted units may not fit. Ideal for areas such as classrooms, offices, or small retail locations, these units can be mounted high on the wall, freeing up valuable floor space.

Both models leverage Bard’s advanced heat pump technology. This technology allows for reverse-cycle functionality, meaning they can provide both cooling in summer and heating in winter. The WA361 model offers a heating capacity of up to 36,000 BTUs while the WA301 provides a slightly lower capacity of 30,000 BTUs, making them suitable for different size requirements.

Energy efficiency is prioritized in these models. They come equipped with high Seasonal Energy Efficiency Ratings (SEER), which ensures lower electric bills and reduced environmental impact. Additionally, the units have been designed to operate quietly, maximizing comfort without the disruptive noise often associated with HVAC systems.

Another notable characteristic is the advanced control system. The Bard WA361 and WA301 feature programmable thermostats that allow users to set specific comfort levels according to their schedules. This not only enhances user control but also boosts energy-saving potential.

Moreover, both models are built with durable materials to ensure longevity and reliability. Their internal components are engineered to withstand harsh conditions, making them a preferred choice for various settings, including industrial environments.

Bard emphasizes ease of maintenance in the design of these units. The filters are easily accessible and can be replaced or cleaned with minimal effort. This feature significantly extends the lifespan of the unit and ensures that it operates at peak performance.

In summary, the Bard WA361 and WA301 air conditioning units represent a blend of innovative technology and practical design. Their energy-efficient operation, compact installation capability, and advanced heating and cooling functions make them exemplary solutions for those seeking reliable comfort control in diverse applications. Whether for small businesses or residential spaces, these units aim to deliver exceptional performance with a focus on sustainability and efficiency.
