Volkswagen Golf Service & Repair Manual: Safety instructions for using extraction and charging equipment
| Before connecting the charging system to the air
conditioning system, make sure that all existing shut-off valves
are closed. |
| Before the charging equipment is decoupled from the air
conditioning system, ensure that the process has finished. The
reason for this is to ensure that no refrigerant oil escapes
into the atmosphere. |
| After the cleaned refrigerant from the charging system has
been charged into an external pressurised gas cylinder, close
the hand shut-off valves on the bottle and the charging system. |
| Do not expose charging system to moisture or use it in a wet
environment. |
| Before performing service work and the charging system,
disconnect the current supply. |
| To reduce danger of fire, avoid using extension cords. If
nevertheless it is necessary to use an extension cable, use an
extension cable with a cross-section of at least 2.5 mm2.
|
| In case of fire, remove external cylinder. |
| If entrained oil from the air conditioning system suction
accumulator is trapped in the measuring beaker supplied, be sure
subsequently to pour the oil into a container that can be
sealed, since the oil contains a small amount of refrigerant.
Refrigerants must not be released into the environment. |
| When the air conditioner service station is switched off, it
must be secured against rolling away. |
