INSTALLATION OF WALL-MOUNTED CONTROLLER
NB: for wall mounting of the controller it is advisable to use
NB: Prior to installation, carefully remove the protective fi lm

INSTRUCTIONS FOR WALL MOUNTING

1. Remove the fastening screw of the controller (FIGURE 8).
2. If a 503 electrical enclosure is used, pass the cables through
the slot at the bottom of the controller and use the holes
provided for fastening.
3. Otherwise, in the wall where you wish to mount the control-
ler, drill holes to match up with the fastening slots (5x8mm)
on the base of the controller; pass the cables through the
slot on the base and screw it to the wall (previously drilled)
(FIGURE 9).
4. Make the electrical connections to the indoor unit terminal
block as per the wiring diagram.
5. Close the controller box and fi x with the screw removed as
described at point 1.
