Note.
- Quick release couplings do not require tools when connecting pipes.
- Unlike conventional connections with nipples and nuts, quick-release connections do not require torque control.
- To disconnect the quick-release connection, use a special puller.
Attention.
When replacing or cleaning air conditioning system components, follow the instructions below:
- When the compressor is removed, store it in the same position as it is installed on the vehicle. Otherwise, oil will enter the low-pressure chamber.
- When connecting pipes, always use a torque wrench to tighten and a wrench on the other side to hold.
- After disconnecting the pipes, immediately seal all openings to prevent dirt and moisture from entering.
- When installing the air conditioner on a vehicle, connect the pipes last. Do not remove the sealing caps from and other parts until it is necessary for the connection.
- Parts that have been stored in a cold place should be allowed to warm up to room temperature before removing the sealing caps. This will prevent condensation from forming inside the air conditioner components.
- Thoroughly remove moisture from the air conditioning system before charging with refrigerant.
- Always replace used O-rings with new ones.
- When connecting the pipes, lubricate the circumference of the sealing rings with oil, as shown in the figure. Make sure that no oil gets on the threaded part.
- The sealing ring must be tightly installed in the pipeline groove.
- When replacing the O-ring, be careful not to damage the O-ring and the pipeline.
- Connect the pipeline until it clicks, then tighten the nut or bolt by hand until it fits snugly. Check that the sealing ring is installed correctly on the pipeline.
- After connecting the line, check for leaks and make sure there are no leaks from the connections. If a refrigerant leak is detected, disconnect the line and replace the sealing ring. Then tighten the connection to the specified tightening torque.
