(Fig. 10) Figure 10 Figure 11 - Push door mount hole cover into upper right-hand-side opening, then secure with a screw. (Fig. 11) Make sure of unhindered opening and appropriate secure sealing of the door. If needed, make corrections after loosening the screws that secure the door.
2.2.3. Replacing cowl - Turn cabinet onto door using appropriate protection support. In case of curved door use support on both sides to avoid oscillation (cardboard support). Unscrew the screw that secures cowl, while keeping the end of cowl from folding down. (Fig. 15, 16) Lastly, remove screw next to boiler insulation. (mounting ease) (Fig. 17) Figure 15 - Figure 16 Figure 17 Lift up cowl, then put replacement part in place.
- Unscrew securing screws. (Fig. 21) Pull out lock. (Fig. 22) Figure 21 - Figure 22 Reassembly is done in reverse order. Rosette and lock cover lid should be snapped in place applying slight pressure. When popping the lock cover lid open, the bolt must be in locked position. ”Turn lock” model - Open door. Pull down rosette using 2 standard screwdrivers. Unscrew securing screws. Pull out lock toward door lining. Push new lock in lock bore of door. Reinsert and tighten securing screws.
- Adjust foil lining. Place the the door panel up to the handle lath into groove on one side of door. Slightly bend door panel. (Fig. 26) Snap door panel into place in groove on other side of door. Push door panel until cylindrical bores on the plate and on the door are concentric. (Fig. 27) Figure 26 - Figure 27 Insert locking-panel, secure with screws. Reinstall lock. Reinstall door. 2.2.6.

Figure 31 2.3. Figure 32 Figure 33 Check the unhindered operation and closing of the freezer door. Electrical components 2.3.1. Replacing lighting device and bulb - Remove screws securing lighting device. (Fig. 34) Detach blocking tab on reflector from the lighting device by pressing the reflector plate. At the same time, push the light shield off of the casing. (Fig. 35, 36) Figure 34 - Figure 35 Figure 36 Unscrew bulb. (Fig.
- Disconnecting electrical wires, removing defective lighting device. Reconnecting electrical wires in new casing. Prior to wiring, wires must be threaded in the appropriate bore of the reflector holder. (Fig. 39) Placement of the socket in the casing so that its securing rib fits in the groove of casing. Screws securing the wires must stand outwards from lighting device. (Fig. 40) Figure 39 - - Insert control switch while holding socket in place with your finger.
- Prior to installing the lighting device, the securing screws must be reinserted into the lighting device so that the tips of the screws overhang by 1-2 mm. These help positioning. (Fig. 45) Install lighting device, with attention to the placement of electrical wires. Figure 44 - Figure 45 Tightening securing screws. Make sure it fits correctly. Then must be no gap between the lighting device and the inner compartment. 2.3.2.
2.3.3. Replacing heating element (cylindrical heating element) : - Remove screws of electrical cover. (Fig. 49, 50) Figure 49 - Figure 50 Remove electrical cover. Disconnect electrical wires of heating element. (Fig. 51, 52, 53) Unscrew and remove the wire clamp. (Fig.
- Turn metal casing of boiler-insulation so that the joint rim becomes visible. While slightly pressing the metal casing of the boiler-insulation, detach the rims. (Fig. 55) Turn out insulation – metal casing and rock wool together – from under the boiler. (Fig. 56) Figure 55 - Figure 56 Loosen screw securing the element, pull out heating element upwards. If the heating element is jammed in the heating tube, then push it out from below with a screwdriver. (Fig.
- Place refrigerator in upright position. Check that the thermostat switch turns freely in the entire control range. Check electrical insulation resistance (with 1000-V electrical insulation resistance metering device.) The insulation resistance RINS > 2Mohm 2.3.4. Replacing heating element (”Half-moon” shaped, as of May 2003): - Unscrew hinge screw on boiler side, slightly bend out side wall of hinge. (Fig. 59) Remove temperature controller from boiler Bend out tabs of boiler casing.
- Position element, adjust its position. The element must be positioned in the direction of hinge. (Fig. 65) Reinsert boiler-insulation, secure. Reinsert boiler-insulation cover, bend back blocking tabs. (Fig. 66) Reinsert temperature controller Snap back wire clamp of heating element. (Fig. 67) Figure 65 - Figure 66 Figure 67 Reassemble loosened end of hinge Check electrical insulation resistance according to 2.3.3. 2.3.5 Replacing temperature sensor - Remove electrical cover. (See 2.3.
- - Thread back new sensor wire. Practical way to do it: From the back panel side, insert a 4x100 standard screwdriver through the lead bore. Slightly push the flat connector of sensor insulation socket onto the edge of the screwdriver, secure with insulating tape. Fold back the end of wire with insulation socket by 180°. Using the screwdriver, pull the wire through the bore, then using that pull through the other end of the wire as well.
- Pop out wire plug from thermostat switch, pull off thermostat switch from the thermostat switch’s axis with a universal plier with protective coating. (Fig. 78, 79) Figure 78 - Figure 79 If the gasket slips off of the thermostat switch, remove it from the bore with a magnetic screwdriver, detach it to the driving bolt. Reinsert the plug into the bore, set aside switch. (Fig. 80, 81) Figure 81 Figure 80 - Lay refrigerator onto door, support if necessary. Remove thermostat cover. (Fig.
- Reinstall thermostat case onto the new thermostat, secure with nut. During assembly make sure that the navigation-securing pin of thermostat fits into the bore of plate. (Fig. 86) Figure 84 - Figure 85 Figure 86 Reinsert thermostat onto panel, secure with screws. Reassemble thermostat wires. Reinsert thermostat cover, secure. Insert thermostat capillary into cabinet approx. 200 mm deep. (Fig. 87) Figure 87 - Place refrigerator in upright position.
- Make sure that the thermostat can be turned within the entire control range. Adjust the capillary spiral that remains outside of thermostat so that it does not overhang from the outline of the cabinet. Seal the point of exit of capillary from the cabinet with rubber sealing. Check electrical insulation resistance according to 2.3.3. 2.3.7 Replacing timer Paragon-type timer - Remove timer cover. (Fig. 89) Remove wire clamp, push down electrical wire. (Fig. 90) Unscrew screws securing timer. (Fig.
Diehl-type timer The Diehl-type timer is not equipped with a separate cover, the control switch is covered with a transparent cover. Its electrical wiring is exactly identical to that of Paragon timer connection. Setting the new timer after replacement: - On the 24-hour control switch, on which one notch means 15 minutes, push out 6 pins radially (1,5 hour period). All the other switch pins must be in pushed-in position. The first pushed out pin on the control switch must be rotated to 0.00 hour.
2.4. Cooling aggregate 2.4.1. Replacing cooling aggregate Attention! The cooling aggregate of refrigerators that are equipped with a temerature controller (as of April 2002) must only be replaced when also replacing the temperature controller or, in the event of a circuit break in the temperature controller, the cooling aggregate must also be replaced at all times. In appliances with no temerature controller only the aggregate needs to be replaced. The assembly instructions must be applied accordingly.
Final assembly of temperature controller, mounting onto aggregate: (This procedure is not necessary for appliances with no temperature controller) Figure 99 Figure 99 presents the necessary elements and tools, for your information. - Cut the wire of the temperature controller to size, according to the size of the wire of the temperature controller on the replaced aggregate. (Fig. 100) From the connection kit, choose the connection elements that are identical to the original temperature controllers.
- Secure temperature controller on boiler-tube of aggregate with 2 screws. Pull protecting socket onto the end of outer securing screw of temperature controller, because the sharp end of screw can cause an accident. (Fig. 103, 104) Figure 103 Figure 104 Installation : - Reassemble aggregate and heating element in opposite order of disassembly. Reinsert electrical connections of temperature controller according to the status prior to disassembly. Screw wire clamp back on.
- Secure freezer compartment with 2 plate screws. Only the original corrosion-proof screws or screws of identical quality may be used. (Fig. 107) Place cooling flange back, secure with 4 plate screws. Again, only corrosion-proof screws may be used. (Fig. 108) Figure 107 - Figure 108 Place refrigerator in upright position, remove any metal shavings from internal areas. Check electrical insulation resistance according to section 2.3.3.
