Heat exchanger or coil replacement:
Before change of coil or heater, inform people that there is work in progress, stop the air curtain through the
controller and disconnect main supply. Make sure that the unit is without tension and the fans are stationary.
Before removing the screws that fix the coil or heater, we have to:
Remove the screws of the outlet (only one side).
Remove all the lamellas of
the outlet and the supports
of the lamellas, too.
Unfixed the outlet (be careful when unfixing the outlet if the installation is horizontal, need to hold the outlet).
The screws are inside of the outlet (you need to unfix the central support of outlet).
