INSTALLATION OF THE "GLL20" UNIT
- Open the packaging of the accessory,
flow frame and intake grid unit, remo-
ve the grid from the packaging and
check that it has not been damaged
during transport.
- Open the cover of the terminal board
on the electric box. Use a tool to relea-
se the pressurised hooks.
- Connect the power supply cables to
the terminal board as indicated in the
wiring diagram.
- Fix all cables using the cable gland.
- Close the cover of the electric terminal
board.
- Insert the electric box into the FCL unit
guide and make sure that the connec-
tors are well attached.
- The electric box must be fixed to the
FCL unit using two screws.
- Remove the intake grid by acting on
the 2 ratchets by ¼ of a turn.
- Hang the frame on the two support
hooks, pay attention to the assembly
position, the corner of the frame with
the AERMEC logo holder must coin-
cide with the corner of the FCL unit
electric box.
- ATTENTION: fix a safety cable snap
hook must then be attached to the
grid frame and the other snap hook to
the fan protection grid.
- Fix the frame to the unit using the 4
screws supplied.
CAUTION!! tighten the screws with
maximum coupling torque of 0.45
Nm. It is advised to use a screwdri-
ver, do not use non calibrated electric
screwdrivers. An excessive coupling
torque will damage the tray irrepara-
bly.
The frame guarantees sealing between
air intake and flow, therefore, it must
be fixed correctly to the unit without
undergoing deformations.
- Fix the intake grill to the safety cable.
- Mount the intake grid, hooking it to the
hinge on the frame.
- Close the intake grid and tighten the
two ratchets (on the side opposite the
hinge) by ¼ of a turn.

support bracket by means of the nuts,
in a way that the unit is level and the
frame rests slightly in the suspended
ceiling.
- Start the fan coil and carry out a fun-
ctioning test.
