TYPES OF THE APROVED SAFETY STANDARDS
Daewoo Electronics 2
PRECAUTIONS
-CAUTION WHEN YOU REPLACE THE COMPRESSOR:
- Do not smoke.Remove all the possible ignition sources and then replace compressor in well-aired places.
- Don´t use welding machines if R600a refrigerant does not exposed.
- In the case of gas leakage, always open the window.
- When cutting the SUCTION, DISCHARGE pipe of compressor, always take caution of the inner pressure of the remai ning gas.
- TAKE OUT POWER PLUG:
- Always take out the power plug from the outlet when doing repairs.
- BE CAREFUL OF ELECTRIC SHOCKS:
- When inspecting the circuit be careful of electric shocks.
- USE PROPER COMPONENTS:
- Always use the component labeled in the service component chart when replacing components for repairs.
- USE PROPER TOOLS:
- Always use proper tools for repairs. If worn out tools are used, it would cause defects in tunning and electrical contact,
leading to accidents.
- When doing repairsinspect the POWERCORDor whether there is fire in the lead wire and make sure they are replaced.
- CUTTING OF LEAD-WIRE:
- For connecting the lead-wire that has been cut off, use soldering or connector and always disconnect the vinyl
tapes.
- CHECK FOR DISCONNECTION:
- After completing the assembly, always measure the disconnection resistance level, and turn on the power after checking it is above 1 MOhm.
- EARTH:
- Check the status of earthing and repair the incomplete ones.
- BE CAREFULL OF CHILDREN:
- There is always the possibility of danger when doing repairs so make sure that children can´t come nearby.
- CLEANING:
- After completing repairs, clean the surrounding area and the refrigerator and tell the consumer about the repairs being
made.
This appliance contains a small amount of refrigerant isobutane (R600a), natural gas with high enviromental compatibi­lity but which is also combustible. When transporting and installing the appliance, care should be taken to ensure that
no parts of the refrigerant circuit are damaged. Refrigerant squirting out of the pipes could ignite or cause an eye injury.
If damage occurs nevertheless, avoid any flames or potential sources of ignition, and air the room in wich the appliance
is standing for several minutes.
* In order to avoid the creation of a flammable gas-air mixture if a leak in the refrigerating circuit occurs, the size of the room in wich the appliance may be sited depends upon the amount of refri-
gerant used. the room must be 1m3 in size for every 8g of refrigerant R600a inside the appliance is
shown on the identification plate inside the appliance.
* Never start up an appliance showing any signs damage. If in doubt, consult your dealer.

MODELS EQUIVALENCE REMARK
- Cosmetic differences, colour, ... relate to the model number. This manual refers to the standard models, but technical contents are similar for the rest of models. Standard models are:
ERF-364AR, ERF-384AR, ERF-394AR, ERF-414AR ERF-367AR, ERF-387AR, ERF-397AR, ERF- 417AR
ERF-364A..EU, ERF-384A..EU, ERF-394A..EU, ERF-414A..EU ERF-367A..EU, ERF-387A..EU, ERF-397A..EU, ERF- 417A..EU
DIFERENCES BETWEEN “ERF-..4A, ..7A” AND “ERF-..4..EU, ..7A..EU”
- These models are basically similar, but for improve the energy efficiency, some components have been changed:
- NEW PARTS FOR ERF-364A..EU, 384A..EU, 394A..EU, 414A..EU:
PCB MAIN AS: 30143B8060 PCB FRONT AS: 30143B6160 WINDOW C/PANEL L/L: 3015507220
- NEW PARTS FOR ERF-367A..EU, 387A..EU, 397A..EU, 417A..EU:
PCB MAIN AS: 30143B9060
- Wiring diagrams and pcb circuits have been changed but rest of components and specifications that don´t appear in this manual are similar to the previous models, so for another spare refer to ERF-..4A Service manual:
