9.20.3 General procedure
NOTE: The illustrations present the unit with front refrigerant charging;
the procedure is the same for the unit with rear charging.
NOTE: The steps described below must be performed on both of the
refrigerant charge/discharge tubes.
Close the narrow point of the charge/discharge tube using pliers (3).
Secure the pliers with a cable tie to hold it in place and closed (4).
NOTE: Use of the pliers avoids refrigerant leaks once the tube is opened;
the seal is not leakproof.
With a mini pipe cutter, remove the soldered upper part of the
charge/discharge tube (5).
Position the charge valve with the little tube (6) on the charge/discharge
tube and solder it on (8).
It is recommended to use a tube with a larger diameter as a union
between the two tubes (7).
NOTE: Protect components during the soldering process.
NOTE: Before inserting the internal valvelet cool the tube using a wet
cloth to avoid it getting burnt.
Remove the pliers and restore the tube at the narrowing point in order to
be able to discharge/charge the gas.
Connect the pressure gauge (digital vacuum gauge to empty the
refrigeration system and heat pump) (9) and the recovery device (10) in
order to reclaim and recover the gas.
Wait for the circuit to be empty (pressure gauge at zero) before working
on refrigerant circuit components.
Complete the steps for discharging/charging refrigerant; reseal the circuit:
– recreate the narrow point in the charge tube.
– remove the charge valve and small tube.
– solder the end of the refrigerant load tube shut.
9.21 Condenser assembly removal
Remove the body (Cf. 9.2 Body removal, on p. 32).
Remove the grille (Cf. 9.5 Grille removal, on p. 33).
Remove the front panel (Cf. 9.3 Front grille removal, on p. 32).
Remove the electronic assembly housing (Cf. 9.11 Electronic assembly
housing removal, on p. 36).
Remove the upper tank (Cf. 9.8 Upper tank removal, on p. 35).
Remove the internal fan (Cf. 9.9 Internal fan removal, on p. 36).
Remove the intermediate tank assembly (Cf. 9.18 Intermediate tank
assembly removal, on p. 39).
Discharge the gas from the refrigerant circuit (Cf. 9.20 Charge/discharge
refrigerant, on p. 40).
NOTE: Before moving every individual assembly-component, ensure that
the electrical wiring and any condensate drain tubes are disconnected.
