charging valve of the condenser slowly, and observe how the liquid sight glass and the condensing pressure
change. If there is refrigerant foam in the liquid sight glass, or the pressure and the admired pressure on the
condition cannot be accordant, that shows the system is lack of refrigerant. As per the actual situation, perform
No3, No4. Until the light glass and the pressure gauge resume normal, shut off the refrigerant charging valve,
and open the liquid supply stop valve slowly. If there is refrigerant foam in the liquid sight glass, or the pressure
and the admired pressure on the condition cannot be accordant, open the refrigerant charging valve to charge
the refrigerant. Repeat the above the procedure, when the liquid supply stop valve is fully open, If there is
refrigerant foam in the liquid sight glass, or the pressure and the admired pressure on the condition can be
accordant, that shows the refrigerant has been charged well. Perform No 5, and record the refrigerant volume.

Solution
1.Remove the dirt in the hole and install a
filter in front of the valve
1.adjust the voltage within ±10%
2.If necessary, open the valve to check or change
the coil. New coil must be dipped and dried, and fill
a layer of glue made of quartz and pitch (the weight
proportion 3:1) between the coil and the shell.
1.Remove the dirt in the hole
2.change the sealed loop
3.Comply with the requirement
1.place the sealed cushion and tighten firmly
and evenly
2.change the sealed part
1.Eliminate the dirt in the hole
2.bad viscosity, enlarge the pressure relief
hole
1.close the switch
2. check if the wiring circuit and the motor coil have
been grounded or in short circuit. check if it is
overload (after troubleshooting),change the fuse
or close the switch to check if the connection is
loose or rusty.
