Bonaire 5 Head Multi Split Outdoor Unit H5M125S2AE

The Bonaire 5 head multi split outdoor unit H5M125S2AE is a powerful 12.5kW outdoor condenser designed for flexible multi-room air conditioning. It can connect with up to five compatible Bonaire indoor units, allowing several rooms or separate zones to receive heating and cooling through one properly designed multi-split system.

This arrangement is an excellent option for properties where installing an individual outdoor condenser for every room would be impractical. By connecting several indoor units to one outdoor unit, the H5M125S2AE can help produce a cleaner exterior appearance while reducing the number of condensers positioned around the property.

The product offered on this page is the H5M125S2AE outdoor unit only. Indoor units, controllers, refrigeration pipework, drainage materials, cables, mounting equipment and installation services are not included unless they are specifically shown in your quotation or order confirmation.

One outdoor condenser for up to five rooms

The key advantage of the H5M125S2AE is its ability to operate with up to five approved indoor units. A suitable indoor head can be selected for each room, allowing the complete system to serve bedrooms, living areas, home offices and other occupied spaces.

Smaller indoor units may be selected for bedrooms or compact studies, while higher-capacity units may be more suitable for living rooms and larger open-plan areas. The final selection must be based on the heat-load requirements of each room and the permitted connected-capacity range of the outdoor unit.

A multi-split system also allows users to control individual indoor zones according to their requirements. However, all connected indoor units share the available output of the outdoor condenser. The system may therefore distribute its available capacity between operating indoor units when several zones are used simultaneously.

Benefits of a Bonaire five-head multi-split system

• Connect up to five approved indoor units to one outdoor condenser
• Provide heating and cooling to multiple rooms
• Reduce the number of outdoor condensers required around the property
• Select different compatible indoor-unit capacities for different spaces
• Control individual indoor zones according to room requirements
• Create a clean and organised exterior installation
• Suitable for new homes, renovations and system upgrades
• Uses R32 refrigerant

Compatible indoor-unit selection

The Bonaire 5 head multi split outdoor unit must be paired with approved Bonaire Optima S2 multi-split indoor units. The exact indoor-unit models, quantities and capacity combination should be selected using Bonaire’s current multi-split combination information.

Connecting five indoor units does not mean that every possible combination of five capacities is approved. The total connected indoor capacity, individual model sizes, refrigeration pipe lengths and installation layout must remain within the manufacturer’s permitted limits.

Before ordering, provide Air Conditioning Trade with the room sizes, proposed indoor-unit locations and preferred number of zones. This information can be used to help identify an appropriate combination for the H5M125S2AE.

Ideal applications

The H5M125S2AE may be suitable for residential and light-commercial properties requiring air conditioning across several separate rooms. Possible applications include:

• Family homes with several bedrooms
• Townhouses with limited outdoor condenser space
• Apartments where an approved multi-split installation is permitted
• Living-room and bedroom combinations
• Home offices and study areas
• Renovation and replacement projects
• Small professional workplaces with separate rooms

Correct equipment selection should not be based only on floor area. Windows, insulation, ceiling height, room orientation, occupancy, local climate and heat-producing appliances can all affect the capacity required for comfortable operation.

R32 refrigerant system

The Bonaire H5M125S2AE uses R32 refrigerant, which is commonly used in modern residential air-conditioning equipment. The refrigeration circuit must be installed, pressure tested, evacuated and commissioned by an appropriately qualified and licensed professional.

Correct pipe sizing, insulation, flare preparation and refrigerant practices are essential. Poor installation can reduce performance, increase energy consumption and potentially affect the manufacturer’s warranty. Refrigerant must never be handled by an unlicensed person.

Professional installation requirements

A five-head multi-split system requires careful design and professional installation. The installer must consider the capacity required in every room, the permitted indoor-unit combination, pipe lengths, vertical separation, electrical requirements and suitable drainage routes.

The outdoor condenser should be installed in a location with sufficient ventilation and manufacturer-specified clearance. Service access must be maintained, and discharged air should not be allowed to circulate back through the condenser. The mounting surface or bracket must also be suitable for the equipment’s operating weight and vibration.

Installation must comply with the manufacturer’s instructions, applicable Australian standards, electrical requirements and local building rules. Apartment or strata installations may also require approval before work begins.
