SECURITY WARNING
1) Personal protection
The air conditioning system offers chemical, mechanical and
electrical hazards. So it is essential to use PPE (Personal
Protective Equipment) to protect your from: refrigerant, oil,
battery acid, debris and engine noise.
2) High pressure
The refrigerant in liquid form under high pressure is a potential
risk. If released to the environment the refrigerant can cause
serious damage to the eyes and skin.
3) Hoses
Check if the manometer hoses are able to be used and move
away from the belts, pulleys and hot surfaces.
4) Hot surfaces
The compressor discharge, exhaust and other engine
components can be very hot.
5) Components in rotation
The fans, pulleys and belts may not be visible under certain
conditions. Special care must be taken in approaching with
hands.
PREVENTIVE MAINTENANCE
To ensure the perfect performance of the air conditioner it is necessary to perform preventive maintenance routines.
This will avoid loss of cooling capacity, extend the life of equipment’s parts and reduce unnecessary stops of the vehicle.
6.1. Preventive Maintenance
6) Welding
The welding should be made with caution, because it can cause
burns and emit some toxic gases. Make sure you are in a
ventilated place.
7) Toxic gas
The refrigerant gas in the presence of flame produces a toxic
gas that can cause severe respiratory irritation. Take special
care indoors, where the refrigerant can cause shortness of
breath.
8) Other precautions
• Care should be taken using ladders and platforms, as there is
a danger of slipping and falling.
• Use full body harness whenever it’s necessary to work in
places over 1.5 meters.
• Never apply heat in containers or pressurized lines.
• Never turn the equipment on with the discharge shut-off valve
blocking the refrigerant flow.
• The refrigeration oil can cause irritation to the skin and eyes,
so avoid prolonged contact.
• Make sure that all screws are the right length and with the
correct grip.
• All components that are not in perfect condition should
be replaced for security reasons.
