Ford Galaxy / Ford S-MAX. Manual — part 657

NOTE: This step is only required when installing a new component.

5. Connect the service unit lines to the filling

connection of the air conditioning system. Install
adapter for evacuation and charging equipment
(air conditioning) FSE number: UCN050500004,
if required.

General Equipment:

Air conditioning service unit

General Equipment:

Adapter for air conditioning

service unit

6. Drain the air conditioning system via the low

pressure connection in accordance with the
service unit manufacturer's instructions.

7.

CAUTION: Make sure that the specified

amount of refrigerant oil is added.

Fill up with refrigerant oil.

Refer to:

Specifications

(412-00 Climate Control

System - General Information, Specifications).
Refer to:

Refrigerant Oil Adding

(412-00 Climate

Control System - General Information, General
Procedures).

8. Evacuate the air conditioning system in

accordance with the service unit manufacturer's
instructions.

9.

NOTE: The system is leak-tight if the
pressure increase does not exceed 20 mbar.

Perform the leak test by closing the hand valves
on the gauge set, switching off the service unit
vacuum pump and observing the low pressure
gauge.

10.

NOTE: This step is only necessary if the
pressure increase exceeds 20 mbar.

Locate and rectify any leaks in the A/C

refrigerant circuit using a leak tester.

General Equipment:

UV leak detector

General Equipment:

Electronic leak detector

General Equipment:

Automatic calibration

halogen leak detector

11. Fill up the air conditioning system with

refrigerant oil.

Refer to:

Specifications

(412-00 Climate Control

System - General Information, Specifications).
Refer to:

Refrigerant Oil Adding

(412-00 Climate

Control System - General Information, General
Procedures).

12. Fill the air conditioning system with liquid

through the high pressure connection.

Refer to:

Specifications

(412-00 Climate Control

System - General Information, Specifications).

13.

1. Open the shut-off valve on the high

pressure side.

2. Switch the service unit to "Fill" mode and

fill the system with the prescribed quantity
of liquid refrigerant (R134a).

14. Fill the air conditioning system with gas through

the low pressure connection.

Refer to:

Specifications

(412-00 Climate Control

System - General Information, Specifications).

15.

1. Open the shut-off valve on the low

pressure side.

2. Switch the service unit to "Fill" mode and

fill the system with the prescribed quantity
of gaseous refrigerant.

3. Add the remaining amount of refrigerant

with the air conditioning switched on. To
do so run the engine at about 1200-1500
rev/min. Set the air conditioning system to
full cooling power and fresh air mode. Set
the blower to the highest setting. Fill with
the remainder of the prescribed fill
capacity.

16. Disconnect the service unit.

17.

1. Close the shut-off valve.
2. Switch off the service unit.
3. Disconnect the service unit lines from the

filling connections of the air conditioning
system.

4. Screw the protective caps onto the filling

connections.

18. To install, reverse the removal procedure.

General Procedures

CAUTION: Collect the refrigerant oil in a clean measuring cylinder.

1.

NOTE: This step only needs to be carried out
when removing the A/C compressor.
NOTE: Rotate the compressor shaft at least 6
to 8 turns when draining the refrigerant oil.

Drain the refrigerant oil from the defective A/C
compressor and dispose of it.

2.

CAUTIONS:

The refrigerant oil top-up quantity must

not exceed the refrigerant oil fill quantity.

If other A/C components are being

renewed in addition to the A/C compressor,
there is no need to top up with additional
refrigerant oil, apart from filling the
compressor.

Top up with the calculated quantity of new
refrigerant oil. See: Specifications (412-00
Heating, Ventilation, Air-Conditioning - General
information, Specifications).
