Service Life; Cleaning The Lossnay Core And Pre-Filter - Mitsubishi Electric Lossnay LGH-100RX3-CAN Technical Manual

CHAPTER 9 Service Life and Maintenance

1. Service Life

The Lossnay Core has no moving parts. This stationary design eliminates vibration troubles and also permits greater
installation flexibility. In addition, chemicals are not used in the heat recovery system. Performance characteristics remain
constant throughout the period of service.
A lifetime test, currently in progress and so far reaching 17,300 hours, has revealed no evidence of either reduction in heat
recovery efficiency or deterioration of materials. If 2,500 hours is taken as the number of hours a conditioner is used during a
year, 17,300 hours corresponds to about seven (7) years.
(This explanation is not a guarantee of the service life of the product.)

2. Cleaning the Lossnay Core and Pre-filter

The Lossnay Core should be cleaned with a vacuum cleaner at least once every 2 years. This will remove the dust that has
accumulated at the surface and restore the functioning of the core to 98 to 100% of the original figure. A brush should not be
used for cleaning because it may trap the dust in the core resulting in clogging.
The air filter on the intake side of the Lossnay Core should be cleaned at least once every year. After cleaning, reinstall the
filter immediately.
