4. 0 Assembly and Manufacturing Process Considerations
For safe installation and trouble-free operation of compressor and air-conditioning system, below instructions
should be carefully read and strictly followed before beginning.
4.1 Removing Rubber Plug
Each compressor is shipped with a dry Nitrogen holding charge between 0.12~0.18MPa (G) (18~26 psig)
and sealed with rubber plugs.
The compressor should be kept horizontal not less than 3 hours and not be declined while removing rubber
plugs. The suction plug should be removed first before pulling the discharge plug to avoid loss of oil. Few
refrigerant oil may be stored in the discharge tube, please take care when removing the discharge plug.
Compressor should be installed into system within 15 minutes after removing the plugs.
Do not use the compressor from which the discharge sound cannot be heard when removing rubber plugs.
4.2 Compressor Mounting
In mobile applications, for the consideration of tubing reliability, it is important to minimize the motion of
compressor during operation. The mounting accessories (grommets and sleeves) that are supplied or
specified by Dalian Panasonic should be used, as shown in Figure 4-1. The upper mounting rubber(rubber1)
can reduce the up-down motion of compressor under vibration and shock conditions;
The mounting parts should be verified by test and based on applications. In severe cases, the vibration
eliminators should be mounted in the compressor discharge and suction lines to reduce the vibration
transferred from compressor to system tubing.

4.3 Residual Moisture
System residual moisture level should be kept less than 200ppm. Normally if the vacuum degree of system
can be achieved, the residual moisture level will also meet this requirement.
