Mitsubishi LGH-40ES-E TECHNICAL MANUAL
A ventilation system that saves energy even while keeping your room comfortable.
A sleek, compact design that fits well with any decor.
Easy maintenance is a plus.
Product Features
POINT
The simultaneous intake/exhaust of air
together with the Lossnay core recovers
temperature and humidity from the room
while ventilating, making this unit both
economical and environmentally friendly.
POINT
A mere 255 mm from front to back, this thin
design takes up a minimum of space even
when suspended from the ceiling of an existing
building.
POINT
In addition to this lightweight and compact design,
connection to the outdoor unit requires just a
200 mm diameter round duct. Neither is there
any need to redo the ceiling after installation.
(Does not require inspection opening.)
