Air Conditioning Safety Regulations - New Holland T4.75F Operator's Manual

Air conditioning safety regulations

The air conditioning system is safe and can be used con-
tinuously without any risk. However, it is important to ob-
serve a few simple precautions, listed below, to avoid any
risk of accident.
1. It is advised never to personally attempt to adjust the
system; any repair work should be carried out by the
experienced technicians of the NEW HOLLAND Ser-
vice Network.
2. Never allow open flames near the air conditioning sys-
tem, as if there is a leak of coolant, a lethal gas: phos-
gene.

3. The oil and coolant mixture is pressurised in the air-
conditioning circuit. The loosening of any connections
or handling of tubing is therefore strictly forbidden. For
the same reason, never unscrew the compressor oil
level inspection cap for any reason.
4. Do not allow heat sources near the air-conditioning
system, as this may cause explosions.
5. Coolant can freeze the skin and, above all, the eyes.
If an accident should occur, proceed as follows:
• if coolant comes into contact with the eyes, wash them
immediately with a few drops of mineral oil, then con-
tinue washing thoroughly with a solution of boric acid
and water (one teaspoon of acid in 1/4 of a cup of wa-
ter) and consult a doctor at once;
• freezing caused by coolant can be treated by gradually
unfreezing the injured zone with cold water and then
applying a grease based cream. In any event, consult
a doctor as quickly as possible
