Service repair no - 82.30.02

WARNING: The air conditioning system is
charged with a high pressure, potentially
toxic refrigerant. Repairs or servicing must

only be carried out by an operator familiar with
both the vehicle system and the charging and
testing equipment.

WARNING: All operations must be carried
out in a well ventillated area away from
open flame and heat sources.

WARNING: Wear eye and hand safety
protection.

CAUTION: Overcharging air conditioning
system will cause excessive head
pressure.

An air conditioning portable Refrigerant Recovery
Recycling Recharging Station for use with R134a
refrigerant incorporates all the features necessary to
recover R134a refrigerant from the air conditioning
system; to filter and remove moisture; to evacuate and
recharge with the reclaimed refrigerant. The unit can
also be used for performance testing and air
conditioning system analysis.

The operator must adhere to the equipment
manufacturer’s instructions.

Refrigerant Recovery

1. Remove dust caps from high and low pressure

connectors.

2. Connect high and low pressure hoses to

appropriate connections.

3. Open valves on connectors.
4. Turn valves on refrigerant station to correct

positions.

NOTE: Operate the refrigerant station in
accordance with the manufacturers
instructions.

5. Turn Process switch to correct position.
6. Turn Main switch to ’ON’.
7. Allow station to recover refrigerant from system.

8. Close valves on refrigerant station.
9. Turn Main switch to ’OFF’.

10. Close valves on connectors.
11. Disconnect high and low pressure hoses from

connectors.

12. Fit dust caps to connectors.
13. Open tap at rear of station to drain refrigerant oil

recovered from system.

14. Measure and record quantity of refrigerant oil

recovered from system.

15. Close tap at rear of station.

Evacuation

CAUTION: Whenever the refrigerant
system is opened, the receiver/drier must
be renewed immediately before evacuating

and recharging the system.

1. Remove dust caps from high and low pressure

connectors.

2. Connect high and low pressure hoses to

appropriate connections.

3. Open valves on connectors.
4. Turn valves on refrigerant station to correct

positions.

5. Turn Process switch to correct position.
6. Turn Main switch to ’ON’.
7. Allow station to evacuate system.

NOTE: If the vacuum reading is below
700mmHg after 15 minutes, suspect a leak
in the system. Partially recharge the

system and check for leaks using an electronic
leak tester. Check suction lines first, then run the
compressor for 5 minutes. Next check the high
pressure lines.

NOTE: The system must be evacuated
immediately before recharging
commences. Delay between evacuation

and recharging is not permitted.
