Safety during maintenance or service:

In order to be safety during maintenance, must obey the following basic attention:

1. During service:

Pay attention to the flame or ignition nearby, particually after welding using gas too,

must turn off the flame first, then can do other maintenance work, because the refrigerant

will produce the toxic air when it touch with flame, sparkle or capacitor.

Do not do the welding work in the airtight or bad air circulation room.

When discharging the refrigerant, must keep the room good air circulation condition.

When cutting the suction pipe or discharging pipe of the compressor, pay attention to the

surplus refrigerant and internal pressure in cooling system pipe

2. Unplug the unit:

When you are ready to proceed the maintenance, must first unplug the freezer first to

ensure the safety.

3．Avoid electrical shock:

Normal when proceeding the maintenance, must open the power supply first. But if you

must check the field wiring or the component of the unit with power supply in, must be

very carefully and don’t touch the live parts. If you find out the wiring is aged, please

replace it in time.

4．Correct use the components:

If the component is damaged and need to be replaced, be sure to replace with the

component with same model，do not use other models or other brand components, and

not use the changed component.

5．Correct use the service tools:

Ensure to use the appropriate service tool right. Otherwise it will cause bad electrical

contact or loose fixing, and the incidence will happen.

6．Wiring connection:

When re-connecting the cut wire, be sure to use soldering method or terminal connection,

and then wrap the connection point with insulation tape, ensure the good connection.

7．Insulation resistance measure:

After completing the service and assembly，must use the multi-meter to measure the

insulation resistance, if it is greater than 1 million ohm, then you can plug on the unit.

8．Grounding test:

After maintenance, use the multimeter to measure the grounding resistance to ensure the

grounding resistance is less than 0.1 ohm.

9．Pay attention to the child or infant nearby:

When maintenance, don’t let the child or the infant nearby.

10．Cleaning:

After service, do the necessary cleaning work and tell the customer the necessary

precaution.

Disassembling and replacing of the components:

When replacing the components, must unplug the unit first, in order to be safety.

1．Replace the thermostat：

Unscrew the fixing screw of the thermostat box, remove the thermostat box, then

remove the old thermostat, install the new thermostat with same model, and reinstall back the

whole thermostat box with same fixing screw.

2．Replace the PTC starter and overload protector of the compressor：

Remove the clamp of the connecting terminal cover of the compressor and the terminal

cover, toward the vertical direction, remove the broken-down starter or overload protector, install

back the new starter or overload protector, then fix back the terminal box cover and its clamp.

3．Replace the door gasket seal:

Remove the old door gasket seal from the groove of the door linear, then install the new

gasket seal into the four sides of the groove, install it oven as possible, open and close the door

several times, ensure that the door is sealed.

4．Replace the compressor：

（1）、 First cut the welding point of the technical pipe of the compressor to discharge the

refrigerant inside the cooling system, then weld the old point to disconnect the pipe to the

compressor, remove the compressor to replace with a new one, pay attention to replace with a

new refrigerant dry filter.

（2）、 Install the new compressor, weld the high pressure side and low pressure side pipe to

the compressor, check the system leakage, after completing vacuum the cooling system,

charge the correct amount refrigerant into the system from low pressure side pipe. After this,

run the unit to check the cooling performance is ok or not, then weld and close the technical

pipe.
