Oil checker r1234yf kit for checking the oil quality of the vehicle's air conditioning system

Available 2pc. WAECO ACT-SRVCTL
Oil checker simple, R1234yf
Oil Checker Easy is a simple and practical maintenance tool that allows you to check the condition of the refrigerant oil in the air conditioning system. By checking the color of the oil sample, you can tell if the oil is fine or needs to be flushed. Problems with the oil can also indicate a more serious problem with the air conditioning compressor, so this device serves as an invaluable early warning system that can prevent costly repairs in the future.

An easy way to check the oil and refrigerant in the air conditioning system
Can help detect compressor damage at an early stage, preventing costly repairs
Can be used when the air conditioner is running
Supplied with service hoses and service connections for low and high pressure sides
For R1234yf

The oil check can only be used in vehicles with an air conditioning system equipped with a low-pressure connection and a high-pressure connection.

An oil check is used to test the condition of refrigerant and refrigerant oil, specifically:
 Shield
 Color change
 Acidification
Refrigerant and refrigerant oil can be assessed visually through the sight glass. In addition, coarse filtration can be performed with a sintered filter.

In the set:
1 carrying bag
2 Sight glass
3 Connection hose (1.8 m) for high pressure connection (red)
4 Quick service interface for high pressure connection (red)
5 Adapter connection (only oil control R-1234yf)
6 Quick service connection for low pressure connection (blue)
7 Connection hose (1.8 m) for low pressure connection (blue)

Use of oil control
1 Installing the oil control
➤ Install the red high-pressure hose on the high-pressure side of the oil
checkers (red).
➤ Install the blue low pressure hose to the low oil pressure side
checkers (blue).
➤ Install the high pressure connection quick service connector to the high pressure hose (red).
➤ Install the low-pressure connection quick-service connector to the low-pressure hose (blue).
➤ Only for oil control of air conditioners with R-1234yf:
Use the included adapters to connect the fittings to the hoses.

2 Connecting the oil control
➤ Check all oil control connections for leaks.
➤ Empty the oil control before first use and after each opening
through the service connection (fig. 2 7, page 3).
➤ Close the low-pressure shut-off valve (Fig. 2 1, page 3) and the high-pressure shut-off valve (Fig. 2 5, page 3).
➤ Connect the high pressure quick coupling (fig. 1 5, page 3)
air conditioner high pressure connection.
➤ Connect the low pressure quick connector (fig. 1 4, page 3) to the low pressure connection of the air conditioning unit.

3 Refrigerant oil/refrigerant check
➤ Start the vehicle engine.
➤ Turn on the air conditioner for at least 5 minutes and then turn it on.
➤ Hold the sight glass (Figure 2 3, page 3) vertically (blue at the top).
➤ Open and close the high-pressure shut-off valve (red) (fig. 2 5, page 3) slowly until the desired fluid level is reached.
➤ Open and close the low-pressure shut-off valve (blue) (fig. 2 1, page 3) slowly until the desired fluid level is reached.
Refrigerant oil is drawn into the sight glass. Refrigerant and compressor oil are separated during the process. If bubbling occurs, close the low pressure shut-off valve (blue) far enough until bubbling stops.
➤ Let the observation glass be up to half full.
➤ Close both controls.
➤ Evaluate the quality of the oil using the color of the pH indicator as shown in the table below:

Color Meaning Action
Red, orange: very acidic Change the refrigerant oil.
Light yellow, yellow: normal condition -
Dark red, yellowish red: the film may be broken Change the refrigerant oil. The compressor may be damaged. Notify the owner of the vehicle.
Orange, yellow The film may be broken Change the refrigerant oil to a new one
improve cooling. The compressor may be damaged. Notify the owner of the vehicle
Light yellow, clear: normal condition -
