SANYO’s Renewal system allows a completely new VRF system, indoor and outdoor units, to be installed using the existing systems pipe work. SANYO’s advanced technology enables the system to work with previously installed pipe work by managing the working pressure within the system down to R22 (33 bar) levels, this ensures the system works safely and efficiently without loss of capacity. The new equipment can offer increased COP/EER by using state of the art inverter compressor and heat exchanger technology.
Having contacted your SANYO supplier regarding pipe work restrictions and gained approval to use the SANYO Renewal System there are three main tests that have to be carried out to ensure that the system can be used effectively.
- Firstly a thorough inspection of the pipe work must be carried out and any damage must be repaired
- Secondly an oil test has to be carried out to ensure that the system has not been subject to a compressor burnout during its lifetime,
- Lastly a VRF Renewal Kit (APR-SLKG) has to be installed within the pipe work to ensure that the system is cleaned of any remnants of oil.
