N Change of the water-cooled condensers
1 For the F 125 Model the front/upper and the
side/back plate
2 Remove the sensing probe from the conden-
ser.
3 Loosen and remove the bolts with which it is
fastened on the base.
4 Unscrew the pipe terminal and pull the pla-
stic pipe of the two ends of the condensers.
5 Remove the cooling agent from the system
and let it flow into a particular container, to be
able to recycle it later after the corresponding
cleaning.
6 Welding the cooling agent pipes from the two
ends of the condenser.
7 For the installation of the new condensers
use the process in reverse order.
O Exchange of the regulating valve
(water-cooled equipment)
1 For the F 125 Model the front/upper and the
side/back plate
2 Close the water stop valve and the supply
pipes for the regulating valve from the back
part of the device.
3 Loosen the pipe terminal and remove the pla-
stic pipe from the pipe holder at the exit of
the regulating valve.
4 Loosen the nuts, which are used for fastening
the regulating valve in the frame of the equip-
ment.
5 Remove the cooling agent from the system
and let it flow in a particular container, to be
able to recycle it later after the corresponding
cleaning
6 Try the capillary tube of the regulating valve
and weld it onto the cold circulation. Then
remove it from the device.
7 For the installation of the new condensers
use the process in reverse order.
P Change of the compressor
1 For the F 125 Model the front/upper and the
side/back plate
2 Remove the cover and pull out the electrical
cable from the terminals of the compressor.
3 Remove the cooling agent from the system
and let it flow into a particular container, to be
able to recycle it later after the corresponding
cleaning
4 Weld the conveyor pipe as well as the suc-
tion pipe of the compressor.
5 Loosen the screws, which is used to fasten it
to the base, and remove the compressor
from the socket of the equipment.
6 For the F125 Model, weld the working/filling
pipe, to be able to weld it on the new com-
pressor.
NOTE.
Replace the dryer filter whenever the
refrigerant circuit is opened. Do not apply the
new filter dehumidifier until all repairs or repla-
cements have been made.
NOTE.
Carefully purged the refrigerant circuit
to remove moisture and non-condensable
gases after the replacement of the condenser.

NOTE.
The water flow passing through the
pressure valve must be adjusted using the
screw in the upper part of its stem until you
have a condensing pressure of 14 bar.
