1. Remove the valve.
2. Check the resistance of the valve winding/
Measure the resistance between the terminals using an ohmmeter ("B1" - "S1"..."S4", "B2" - "S1"..."S4").
- Nominal resistance - 20-23 Ohm
If the resistance is not as specified, replace the valve.
3. Remove the actuator.
4. Check the operation of the valve.
a) Apply battery voltage to terminals "B1" and "B2" and, alternately grounding the terminals "S4"-"S3"-"S2"-"S1" in the order given, make sure the valve opens gradually.
b) Apply battery voltage to terminals "B1" and "B2" and, alternately grounding the terminals "S1"-"S2"-"S2"-"S3"-"S4" in the order given, make sure that the valve gradually closes.

If the valve operates differently than described, replace it.
5. Install the actuator.
6. Install the solenoid valve.
