Service Life; Cleaning The Lossnay Core And Pre-Filter - Mitsubishi Electric Lossnay series Technical Manual

CHAPTER 9 Service Life and Maintenance

1. Service Life

The Lossnay Core has no moving parts, which eliminates vibration problems and permits greater installation flexibility. In
addition, chemicals are not used in the energy recovery system. Performance characteristics remain constant throughout the
period of service.
A lifetime test, currently in progress and approaching thus for 17,300 hours, has revealed no evidence of either reduction in
energy recovery efficiency or material deterioration. If 2,500 hours is assumed to be the number of hours an air conditioner is
used during a year, 17,300 hours equals to about seven (7) years.
(This is not a guarantee of the service life.)

2. Cleaning the Lossnay Core and Pre-filter

Remove all dust and dirt on air filters and Lossnay cores at regular intervals in order to prevent a deterioration in the Lossnay functions.
Guideline: Clean the air filters once a year. (or when "FILTER" and "CLEANING" are indicated on the remote controller)
Clean the Lossnay cores once two year. (Clean the Lossnay cores once a year If possible.)
(Frequency should be increased depending on the extent of dirt.)
