BRACKET AS 4397477 - Caterpillar

Personal injury can result from contact with refrigerant.This system is under pressure at all times, engine running or not. Heat should never be applied to a charged system. Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury.Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant.Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, release it slowly in a well ventilated area.Personal injury or death can result from inhaling refrigerant through a lit cigarette.Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death.Do not smoke when servicing air conditioners or wherever refrigerant gas may be present.Before any checks of the air conditioning and heating system are made, move the machine to a smooth horizontal surface. Lower all implements to the ground. Make sure the transmission is in neutral or park and that the parking brake is engaged. Keep all other personnel either away from the machine or where they can be seen.

Effective July 1, 1992 regulations prohibit the venting of any refrigerant into the atmosphere. Refer to Caterpillar publications Service Manuals, SENR3334, SENR5664, and NEDG5065 for the proper procedure, the proper equipment, and the proper tools needed in order to reclaim refrigerant from any Caterpillar equipment.
If service work is required on the air conditioning system, the refrigerant must be reclaimed before removing or installing components.One exception exists. Many in-line dryers have quick couplers. Refer to the Operation and Maintenance Manual, "In-Line Refrigerant Dryer - Check/Replace" for the proper procedures.Use the following procedure for reclaiming the refrigerant in all other situations.
Install the manifold gauge set (6). Make sure that both valves are closed. Turn the valves clockwise in order to close the valves. Refer to Testing and Adjusting, "Manifold Gauge Set (Refrigerant) - Install"for proper instruction.
Attach yellow charging hose (3) of the manifold gauge set to the inlet (8) on the recovery station.
Slowly open valves (1) and (2) in order to release the air from the yellow charging hose. Ensure that the valves on refrigerant tank (13) are open. One valve is for vapor and the other valve is for liquid.
Plug the recovery station into an electrical outlet and turn the power switch ON. This switch is located on control panel (7) .
Press the "Compressor Start". The
