INSTALLATION OF THE "GLL20N" UNIT
- Open the packaging of the accessory,
flow frame and intake grid unit, remove
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 release 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 screwdriv-
er, 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 func-
tioning test.
