Refer to "Chapter 3 Section 9 Performance comparisons with various
heat recovery units and ventilators".
For the ceiling embedded-type, the unit is installed in the false ceiling, so
an inspection hole is required at the Core and filter removal section and
fan maintenance section.
Refer to the catalog for details.
Periodic inspection and cleaning of the Lossnay Core and air filter is
necessary. Refer to "Chapter 9 Service Life and Maintenance" for details.
Class 1 ventilation refers to mechanical ventilation (forced simultaneous
air supply/exhaust) using both intake and exhaust fans for suction feed.
All Lossnay models (with built-in air-feed fans) are Class 1 ventilators.
The ventilation method is classified in relation to the degree of natural
and/or mechanical ventilation employed.
