Ditrubance Cause Trouble-shooting Remedy No-Frost Check if blade is lockedmechanically. Fittings for fan or airguiding duct are adjustedor replaced. Check if blade is fixedcorrectly on shaft. Blade must turn so thatair flow only can besucked in and blown outin the right places. Blademust cover 10mm ...

Starting device with HST Connect a voltmeter between terminals 10 and 13 on the start-ing device. If no voltage can be measured, either the mainscable or the socket is defective. Connect a voltmeter between terminals 10 and 14 on the start-ing device, It no voltage can be measured, a defective ther-...

1.6. The PTC Starting Device It should be noted that starting device 1 03N001 2, which is usedfor the freezing compressor of refrigerator/freezer uprights, isinstalled differently than is starting device 1 03N001 1, which isused for the refrigerating compressor. On starting device 1 03N001 2, the N ...

Actual Evacuation After mounting of the filling hose, the system is ready for theactual evacuation. Evacuate until a stable vacuum of 1 mbar hasbeen reached. Check for stability of the vacuum by closing thevalve for the vacuum pump (12). If the vacuum gauge needle fallsappreciably, possible leakage ...

First Evacuation of Appliances with R600a in the System 1. Drilling and tapping of filter drier, after thorough cleaning where the gasket of the tongs must be tight. 2. Mount the hose - open the valve. The system can then be blown through with nitrogen (see section: The BlowingProcess). 3. Close the...

Actual Evacuation and Filling of R600a 1. Mounting of the filling hose with spherical valve - see fig. 7. Thereafter, evacuate. 2. Testing of the microscales with a weight.3. Connect the refrigerant tank to the filling hose (16), and open the valve (9). Evacuate the filling hose andthe manifold by o...

2.1.1. Opening the Refrigerating System for Repairs with Recovery of Refrigerant. If a hermetic refrigerating system is to function correctly andhave a reasonably long life, it is essential that the amount ofimpurities pre-sent in the system, i.e. moisture, foreign gases,dirt, etc., be kept at a min...

Pinch the charging pipe with pliers. Remove the service valveand solder the hole together. Brush off all solderings in the system and check for possibleleakage with an electronic leak detector. Check the pressure side when the compressor is in operation and the suction sidewhen the system is pressur...

Evacuation with Recovery of Refrigerant 1. Drilling and tapping of filter drier after thorough cleaning where the gasket of the tongs must be tight. 2. Mount the refrigerant bag - open the valve. 3. Close the valve after pressure equalizing-dismount the refrigerant bag. 4. Mount the refrigerant bag ...

Opening the System 7. Drilling and tapping of process pipe. 8. Connect dry nitrogen and equalize the pressure. 9. Open the system with capillary tube scissors and removethe drilling and tapping valve. The tongs are removedfrom the used filter drier and dry nitrogen (N2) is now blownthrough the proce...

2.1.2. Emptying used Refrigerant to Pressure Vessel from Refrigerant Bag Connect the suction valve on the emptying unit with hose to theoutlet valve on the emptying rack for refrigerant bags. Open themain valve and the valve for the bags to be emptied. Connect the pressure valve on the emptying unit...

2.1.3. Opening the Refrigerating System with Refrigerant R134a for Repairs As R134a has other properties than the R12 used till now, it isimportant to note the following before opening the hermeticrefrigerating system: 1. Service Tools Do not use service tools that have been used for chlorine- conta...

2.2. Replacing the Filter Drier Some moisture and impurities will always be accumulated inthe filter drier, both from residue left in the system afterinstallation and from contamination given off by the compres-sor, pipe system and refrigerant. When repairs are made to the refrigerating system, the ...

2.3. Replacing the Compressor If trouble-shooting in the electric circuit or volumetricmeasurements indicate that the compressor is defective, a newcompressor must be installed. The following procedure is to be used: Ensure that the new compressor is ready for installation.Replace the electrical equ...

2.5. Replacing the Thermostat Uprights Dismount the phial tube and straighten out the phial. Draw offthe insulation, if any, around the phial. The phial can now bedrawn out of the lead-in pipe from the back of the unit.After the plug has been removed from the socket, remove thecover for the top pane...

Positioning of the Thermostat Phial in NFG 307 from Serial No. 501----- In order to ensure the proper functioning of the thermostat 90 mm of the free end of the capillary tube is to serve as thermostatphial. In case of failing thermostat functioning and a possiblereplacement of the thermostat, be su...
