3. Unscrew and take out the nuts that fix it in the base.
4. Unscrew the brackets of the tub and disconnect the plastic pipes from the
two end of the condenser.
5. Get the refrigerant out of the system and let it in a tank to use it again after
treat it.
6. Unweld the pipes of the cooling installation from the two end of the
condenser.
NOTE. Purge carefully the cooling circuit to remove the excess of humidity
and the no condensation of gas after the substitution of the presostathic
valve.
NOTE. Sustitue the dehydrate filter every time the cooling refrigerant is open.
Do not put the dehydrate filter until the reparation or substitution process is
finished..
7. To install a new condenser follow the instructions on the other way round.
NOTE. Purge carefully the cooling circuit to remove the excess of humidity
and the no condensation gas after the substitution of the condenser..
L. SUSTITUTION OF THE PRESOSTATHIC VALVE (UNIT COOLED BY
WATER)
1. Take out frontal/upper panel and back side panel in models MF22, MF30,
MF41 and MF51 and left side panel in model MF61.
2. Close the stopcock of water and disconnect the pipe from the presostathic
valve from the back side of the unit.
3. Get the refrigerant out of the ysstem and let it in a tank to use it again after
treat it.
4. Unscrew and take out the capillary pipe from the presostathic valve from
the refrigerator circuit.
5. To Install the new presostathic valve follow this instruction on the other way
roundl.
NOTE. The flow of water that go through the presostathic valve has to be
adjusted using the screw located in the upper side of its rod until the
condensation pressure is of 8.5 bar in MF22 and 17 bar in MF30,41,51,61..
M. SUBSTITUTION OF THE CONDENSER
1. Take out the forntal/upper panel and back lateral panel in models
MF22,MF30, MF41 and MF51 and frontal panel in model MF61.
2. Take out the lid and disconnect the electrical cable from the connections in
the condenser.
3. Get the refrigerant out of the system and let it in a tank for using it again
after drain it.
4. Unweld and disconnect the impulsion pipe and the aspiration pipe pof the
compresor.
5. Unscrew the screws that fix it in the base and take the compresor out of the
base of the unit.
6. Take out hte auxiliar/load pipe and reserve it to weld it again in the
compresor.
7. To install the new compresor follow these instructions on the other way
round .
NOTE. Sustitute the dehydrated filter every trime the refrigerator circuit is
open. Not install the new filter unit all the substitution or reparation process
has finished..
NOTE. Purge carefully the cooling circuit to remove the excess of humidity
and the no condensation gas after the sustitution of the condenser..
