Commercial Cassette Air Conditioning Installation | Orsman Road
Climate Flow Limited successfully completed the installation of two Mitsubishi Heavy Industries cassette air conditioning systems at a restaurant on Orsman Road, London. The project included two ceiling cassette indoor units, two dedicated outdoor condensing units and complete refrigerant, drainage and electrical installations, all completed in less than two days.

Project Overview
The restaurant required an efficient cooling solution capable of providing reliable comfort for customers and staff while maintaining a clean, professional appearance. Climate Flow Limited designed and installed two independent Mitsubishi Heavy Industries cassette systems to deliver balanced airflow and energy-efficient operation throughout the premises.

Equipment Installed
- 2 Mitsubishi Heavy Industries ceiling cassette indoor units
- 2 Mitsubishi Heavy Industries outdoor condensing units
- 2 condensate drain pumps
- Insulated refrigerant pipework
- Electrical interconnecting cables
- Condensate drainage system
Scope of Work
- Installation of two ceiling cassette indoor units
- Installation of two outdoor condensing units
- Core drilling through reinforced concrete walls and ceilings
- Installation of steel channels and threaded rods for secure suspension
- Installation of insulated refrigerant pipework (1/4" × 5/8")
- Installation of condensate drainage and overflow pipework
- Installation of two condensate drain pumps
- Pressure testing, deep vacuum evacuation and commissioning
- Operational testing and performance verification

Project Challenges
During the installation, the customer requested changes to both the indoor unit locations and the refrigerant pipework route after work had already begun. Our engineers reviewed the revised layout, redesigned the installation to suit the customer's preferences and completed the project without compromising installation quality or manufacturer requirements.
The reinforced concrete structure required specialist core drilling equipment together with heavy-duty suspension fixings. Steel channels and threaded rods were installed to securely support both cassette units. The installation also included 5/8" refrigerant pipework, condensate drainage with overflow protection and dedicated condensate pumps to ensure reliable operation.

Results
- Complete installation finished in under two days
- Professional and tidy workmanship
- Excellent cooling performance throughout the restaurant
- Reliable condensate removal using dedicated drain pumps
- Pipework installed neatly and efficiently
- Customer extremely satisfied with the final installation
