ACCESSING THE MAIN COMPONENTS
The air-conditioner is accessible from all sides by removing the
various panels.The front and/or side panels are opened in 2 differ-
ent ways:
FRONT PANELS
All the front panels are hinged and fitted with locking latches and
seal. All the front panels are opened and closed using a tool (typi-
cally a screwdriver) to open and close the latches.
Once the latches have been opened, the front panels can be
swung open and then removed vertically to simplify the service
operations on the air-conditioner, especially where there is little
space available. Opening the front panels provides access to all
the components in the air-conditioner involved in routine mainte-
nance. The number of front panels depends on the capacity of the
air-conditioner.
SIDE PANELS
All the side panels are accessible and removable.
Nonetheless, these do not need to be removed for routine main-
tenance operations. This means that, if necessary, a series of units
can be installed next to each other.
The side panels are fastened by screws.
These are accessible directly on the side panel by removing the
black plastic caps.
BACK PANELS
Fastened by normal self-tapping screws, these are not accessible
as when installed the back of the unit is against the wall
INSIDE PANELS
The compartment that contains the fans and the heaters is pro-
tected and insulated by a metal plate.
This is for safety reasons, so as to not have to shut the unit down
during normal maintenance operations.
WARNING:
before restarting the air-conditioner, always
check that all the panels have been correctly replaced.
