How To Install a Dunham Bush Cassette AC:

Correct installation guarantees the best performance and increased lifetime value of the Dunham-Bush Cassette AC units:

Pre-Installation Needs:

During the pre-installation process of the Dunham Bush ceiling cassette air conditioner, the ceiling structure and space availability for indoor units and plumbing are assessed during a site inspection.

• Power Supply Check: Verify the proper phase and voltage supply; see technical data.
• Plan a downward slope for the condensate drain pipe to guarantee smooth water flow.
• Ventilation: Ensure the outside unit has enough ventilation to allow unimpeded airflow.

Installation of Indoor Units:

• Ceiling Cut-Out, usually 950×950 mm, matching the size of the interior unit and front grill.
• Suspension System: Suspend the interior unit firmly within the ceiling cavity using a bracket and threaded rod.

Wiring and Piping:

• Connect copper refrigerant pipes according to the specified size.
• Insulate the pipes to stop condensation.
• Link communication cable or control cable between the interior and outdoor unit.

Installation of Outdoor Units:

• Use rubber pads on a level concrete slab, or strong metal stand. This is done to eliminate vibrations.
• For appropriate heat dissipation, keep at least 12 inches of space around the device.
• Piping Connection: Match the pipe diameters of the indoor units. Ensure that the connections are not only seamless, leak-proof, but also solid tight.
• Electrical Connections: Employ a suitably grounded power source and a separate MCB.

System Testing and Commissioning:

• Conduct nitrogen pressure tests to look for refrigerant leaks.
• Using a vacuum pump, remove moisture and air from the system.
• Refrigerant Charging: If required, R-32 refrigerant should be topped up depending on pipe length.
• Trial Run: Start the unit and watch the temperature decline, noise level, and airflow.

Suggestions for maintenance:

• To maintain airflow and cleanliness, clean air filters every 2–4 weeks.
• Check the drain pipe to make sure it isn't blocked to prevent water from leaking.
• Professional Servicing: Plan bi-annual maintenance inspections with qualified professionals.
