UNIT DISASSEMBLY 7
Model 53SSB009---1, is provided with quick coupling
connesctions for fixed installation that allow the units to
be disconnected up to a maximum of six times without
impairing the performance of the air conditioner.
This operation must always be carried out by
qualified and authorized personnel.
On model 53SSB009---1, unscrew the fixing screw
using the "TORX" screwdriver (size 10 with holed bit)
and remove the closing cover.
Disconnect the electrical connector.
Loosen the fixing clamp of the small tube that takes
condensing water to the outdoor unit, taking care to
dischargetheremainingcondensatewaterintoapanorthe
indoor unit collection tank.
With a screwdriver, unscrew partially the 4 screws of the fixing bracket flexible pipe.
Using two fixed wrenches (0.94" (24 mm) on turning nut and 0.75" or 0.83" (19 or 21 mm) on fixed
parts) operate on the turning nut, unscrew and remove the quick coupling connections.
Remove the 4 screws of the fixing bracket flesible pipe.
Protect the connection end parts with caps. Position the outdoor unit outside in the desired
position passing the flexible pipe through the hole Ø 2.4" (60 mm) in the wall.
The two parts of the air conditioner should remain split for the shortest possible time.
For unit re-assembling repeat the previous operations in reverse order.
For re-connection of the quick coupling, apply a tightening torque of 17 to 20 Ft-Lbs.
Quick-connect couplings removal.
Switch the unit off, turning the mode selector counter-
clockwise to symbol • and remove the plug from the
power supply socket.
