LGH-F1200RX type
Note: The double control board for the
LGH-F1200RX has two M-NET addresses.
(1) The ceiling embedded type: 300, 470, 600 and 1200 CFM types are available. Select an adequate model according to the room size and air
volume for the application and sound levels.
(2) LGH units are supplied with two speed blowers. Speeds are “LOW” and either “HIGH” or “EXTRA HIGH” as selected. All types have an extra-
high speed. This setting is for a long duct run or when a large air volume is required. The positive and negative pressures of the room can also
be adjusted with dampers.
(3) The units have a low-sound design, however, for further sound reduction a silencer-type supply/return grille for supply/return air in the room, a
silencer box for reducing air sound into the room, and a flexible silencer should be used.
