GENERAL INFORMATION

Remedial actions
If an accident involving R134a should occur, conduct 
the following remedial actions:

l

If liquid R134a enters the eye, do not rub it. 
Gently run large quantities of eye wash over 
affected eye to raise the temperature. If an eye 
wash is not available, cool, clean water may be 
used to flush the eye. After rinsing, cover the 
eye with a clean pad and seek immediate 
medical attention.

l

If liquid R134a is splashed onto the skin, run 
large quantities of water over the affected area 
to raise the temperature. Implement the same 
action if the skin comes in contact with 
discharging cylinders. Wrap the contaminated 
body parts in blankets (or similar materials) and 
seek immediate medical attention.

l

If the debilitating effects of inhalation of R134a 
vapour is suspected, seek fresh air. If the 
affected person is unconscious, move them 
away from the contaminated area to fresh air 
and apply artificial respiration and/or oxygen 
and seek immediate medical attention.

WARNING: Due to its low evaporating 
temperature, R134a must be handled with care. 
R134a splashed on any part of the body will 
cause immediate freezing of that area. Also, 
refrigerant cylinders and replenishment trolleys 
when discharging will freeze skin to them if 
contact is made.

Service precautions
Observe the following precautions when handling 
components used in the air conditioning system:

l

Air conditioning units must not be lifted by their 
hoses, pipes or capillary lines.

l

Hoses and lines must not be subjected to any 
twist or stress; the efficiency of the system will 
be impaired by kinks or restrictions. Ensure that 
hoses are correctly positioned before tightening 
couplings, and ensure that all clips and supports 
are utilised.

l

Flexible hoses should not be positioned close to 
the exhaust manifold (less than 100mm) unless 
protected by heat shielding.

l

Completed assemblies must be checked for 
refrigeration lines touching metal panels. Any 
direct contact of components and panels may 
transmit noise and so must be eliminated.

l

The appropriate torque wrench must be used 
when tightening refrigerant connections to the 
stipulated value. An additional spanner must be 
used to hold the union to prevent twisting of the 
pipe when tightening connections.

l

Before connecting any hose or pipe, ensure that 
refrigerant oil is applied to the seat of the new 'O' 
rings, BUT NOT to the threads of the 
connection.

l

All protective plugs must remain in place to seal 
the component until immediately prior to 
connection.

l

Ensure components are at room temperature 
before uncapping, to prevent condensation of 
moisture from the air that enters it.

l

Components must not remain uncapped for 
longer than 15 minutes. In the event of a delay, 
the caps must be fitted.

l

When disconnecting, immediately cap all air 
conditioning pipes to prevent ingress of dirt and 
moisture into the system.

l

The receiver/drier contains desiccant which 
absorbs moisture. It must be positively sealed at 
all times. A receiver/drier that has been left 
uncapped must not be used, fit a new unit.

l

The receiver/drier should be the last component 
connected to the system to ensure optimum 
dehydration and maximum moisture protection 
of the system.

l

Whenever the refrigerant system is opened, the 
receiver/drier must be renewed immediately 
before evacuating and recharging the system.

l

Use alcohol and a clean lint-free cloth to clean 
dirty connections.

l

Ensure that all new parts fitted are marked for 
use with R134a.

When a major repair has been completed, a leak test 
should be conducted; refer to the Air Conditioning 
section of this manual for the correct procedure.
