17.2. Instruction for use of coolant
- Liquid R-134a coolant with the high content of volatiles. Its hit on skin can end with a frostbite therefore during the work with coolant it is necessary to put on protective gloves.
- As standard measures of protection during the work with coolant it is necessary to use points for protection of eyes. At hit of coolant on clothes or protective equipment immediately wash out the struck place a large amount of water.
- Liquid R-134a coolant is stored in containers (cylinders). You store a cylinder with coolant at a temperature no more than 52 °C.
- For check of tightness of air conditioning system use the electronic sensor. Keep in mind that R-134a coolant after contact with a flame decays with release of very poisonous gas.
- Use only the recommended oil for lubricant of elements of the air conditioning system as, otherwise, the system can fail.
- PAG lubricant intensively absorbs moisture from atmospheric air therefore it is necessary to observe the following precautions:
– at separation of components of the air conditioning system immediately close connections by the corresponding covers for an exception of hit of moisture in system;
– at installation of new components of the air conditioning system remove from them protective covers just before their installation;
– connect tubes and hoses of the air conditioning system as soon as possible to reduce hit in system of moisture;
– use lubricant for the air conditioning system only from a tight container.
- If there was a casual discharge of the air conditioning system, before service of system air a workplace.
