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 3 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

Any heat pump is more critical of proper operating charge and an adequate duct system than a straight air conditioning unit. All duct work, supply and return, must be properly sized for the design airflow 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.

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 one 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.

These units are suitable for 0 inch clearance to combustible material. See Wall Mounting Instructions and Figures 3, 4, 5, 6 & 7 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.

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 inch.

NOTE: If no return air duct is used, applicable installation codes may limit this cabinet to installation only in a single story structure.

Any grille that meets with 5/8 inch louver criteria may be used. It is recommended that Bard Return Air Grille Kit RG2 through RG5 or RFG2 through RFG5 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 2-inch pleated filter is supplied with each unit. The filter slides into position making it easy to service. This filter can be serviced from the outside by removing the filter access door.

CONDENSATE DRAIN – EVAPORATOR

A plastic drain hose extends from the drain pan at the top of the unit down to the unit base. There are openings in the unit base for the drain hose to pass through. In the event the drain hose is connected to a drain system of some type, it must be an open or vented type system to assure proper drainage.

CH3S1, CH5S1, CH4S1 specifications

Bard CH3S1, CH4S1, and CH5S1 represent a formidable trio of advanced technologies in the field of AI-driven natural language processing. These models are designed to facilitate seamless communication, enhance productivity, and deliver personalized experiences across various applications.

One of the main features of the Bard CH series is its ability to understand and generate human-like text. This is achieved through deep learning algorithms that analyze vast datasets to learn language patterns, context, and nuances. The CH3S1 model, for instance, excels in basic conversational tasks, making it suitable for customer support, virtual assistants, and simple content generation. Its training allows it to respond efficiently to user inputs while maintaining clarity and engagement.

As we progress to the CH4S1 model, we observe significant enhancements in contextual understanding. This model can handle more complex conversations, making it adept at tasks requiring greater cognitive processing, such as technical support and nuanced dialogue-based applications. The increased parameter count and refined training methods contribute to its ability to grasp intricate sentence structures and varied linguistic styles, leading to more coherent and relevant responses.

Building upon the capabilities of its predecessors, the CH5S1 model represents the pinnacle of the Bard CH series. It integrates advanced features such as multi-modal processing, allowing it to work with text, images, and even sound. This model is engineered to perform in more specialized fields, such as healthcare, legal, and creative writing, where precise language and context are critical. The CH5S1 leverages feedback loops from real-time interactions to continuously improve its understanding and output, making it not only a tool for communication but also an intelligent partner for businesses and individuals alike.

In terms of technology, all three models utilize transformer architecture, which has proven effective in tasks requiring attention and context retention. They also implement reinforcement learning techniques to adapt and refine their models based on user engagement data. Furthermore, security and data privacy are prioritized, with strict adherence to ethical AI guidelines to ensure user trust.

Overall, the Bard CH series signifies a leap forward in artificial intelligence, combining advanced linguistic capabilities with a user-centric approach, thus redefining how we interact with machines and enhancing our digital experiences.
