1. Introduction VINOTEMP assumes no responsibility for any repairs made on products by anyone other than authorized service technician This manual has been prepared to provide the information on installing, servicing, troubleshooting and repairing procedures for the WINE-MATE VINO3500HZD, 4500HZD, 6500HZD and 8500HZD cooling units. I.
• • • • • • • Use dry nitrogen to purge the system. Do not overcharge the refrigeration system. Do not leave replacement compressor open to the atmosphere for more than 10 minutes. Do not operate the compressor without refrigerant charge in the system. Do not use the compressor if the rubber plugs on the replacement compressor appear to have been tampered or removed. Always replace the filter-drier when performing any repairs on the sealed system. The filter-drier must be cut from the sealed system.
2. Component Information and Access This section provides you the component information and access inside the cooling unit. The components and their locations are shown Figures 2-1 through 2-11 below. I.
II. Component Access 1) Removing the Outer Cover 1. Unplug the cooling unit or disconnect power. 2. Remove the cooling unit from the wine enclosure. 3. To remove the outer cover, remove all screws from each side. Figure 2-2 2) Removing the Inner Styrofoam Once the outer cover is removed, this will expose the inner styrofoam pieces. The top large styrofoam seals off the condenser and evaporator fan compartments. To gain access to the other components, the styrofoam will need to be removed.
Figure 2-3 Figure 2-4 -7-
Figure 2-5 3) Removing the Fan Plate 1. Disconnect the power cord, compressor cord and temperature controller wires from the terminal block. 2. Remove the 6 rivets on the front and rear sides. 3.
Figure 2-7 4) Removing the Temperature Controller Figure 2-8 1. 2. 3. 4. 5. Unplug the cooling unit or disconnect power. Remove the outer cover. Remove all the lower side styrofoam pieces. Disconnect all the wires from the temperature controller. Press the 2 snappers to release the controller and then pull it out of the opening.
5) Removing the Thermistor 1. 2. 3. 4. 5. 6. Unplug the cooling unit or disconnect power. Remove the outer cover. Remove all the upper and lower side styrofoam pieces. Remove the fan plate. Disconnect the thermistor from the temperature controller. Remove the thermistor from the mounting clip on the front of the evaporator. 6) Removing the Fans Figure 2-9 The 2 condenser and evaporator fans are attached to the horizontal fan plate. They are the same and all powered up at the same time. 1.
6. Remove the overload protector by pulling straight out away from the compressor terminal. Figure 2-10 9) Removing the Compressor Figure 2-11 1. 2. 3. 4. Unplug the cooling unit or disconnect power. Remove the outer cover. Remove all the upper and lower styrofoam pieces. Remove the fan plate.
5. Place piercing valves onto the process tubes and discharge the refrigerant into an approved R134a recovery system. 6. Use a tubing cutter to remove the suction line and discharge line from the compressor. 7. Remove 4 nuts (11mm) from the feet of the compressor. 8. Remove the compressor Note: Any time the sealed system is accessed the filter-drier must be replaced. It is best to cut the drier out of the system, then braze on a new one. 10) Removing the Condenser 1. 2. 3. 4. 5.
3. Servicing and Diagnosis This section instructs you how to service each component inside the cooling unit. I. Component Checking 1) Terminal Block Figure 3-1A (3 button controller) A. Live Line (115VAC/60Hz): red shrunk wire from the power line; B. Neutral Line: white shrunk wire from the power line; C.
D. Fan Wires: black shrunk wire from the fan terminal connecting the black wire from the controller compressor output; white shrunk wire from fan terminal connecting the neutral line; Figure 3-1B (5 button controller) A. Live Line (115VAC/60Hz): red shrunk wire from the power line B. Neutral Line: white shrunk wire from the power line; C.
A. Resistance 1. Unplug WINEMATE cooling unit or disconnect power. 2. Remove the terminal cover from the compressor. 3. Remove the start relay and overload protector from the compressor. If wiring is removed from the start relay and/or overload protector, carefully label each wire according to its proper location. 4. Set the ohmmeter scale to the lowest setting. 5. Touch and hold one ohmmeter probe to the C (common) terminal, then touch and hold the other probe to the R (Run) terminal.
3) Start Relay A start relay’s function is to energize and de-energize the compressor’s start winding. The coil of the current type relay is connected in series with the run winding. When current flows through the coil, a magnetic force is produced, pulling the relay plunger up. With the relay plunger up, it connect the start winding and the run winding at the same time and the compressor starts.
the temperature controller will turn on the compressor and fan motors. Once the selected temperature is sensed, the controller will turn off the cooling unit. A. Resistance 1. Unplug WINE-MATE cooling unit or disconnect power. 2. Disconnect the red and white wires connected to the input 7 and 8 of the temperature controller. 3. Touch and hold one ohmmeter probe to one terminal on the temperature controller, then touch and hold the other probe to the other terminal. 4.
1. The WINE-MATE unit needs to be plugged in. 2. Locate the red and white wires going to the temperature controller input 7 and 8. 3. Set the voltmeter to the AC 200 scale. 4. Touch and hold one voltmeter probe to one of the wire terminals, then touch and hold the other probe to the other wire terminal 5. The voltmeter shall show a reading of 115 volts. C. Output Live Voltage 1. In order to test the output of the temperature controller, the WINE-MATE cooling unit must be plugged in and powered up. 2.
4. The ohmmeter shall show a reading of tens ohms. 5. Reconnect the wires to the proper terminals as previously marked. B. Live voltage 1. The WINEMATE unit needs to be plugged in and turned on. 2. Locate the black and white wires from the fan motor being tested and follow them back to the terminal block. 3. Set the voltmeter to the AC 200 scale. 4. Touch and hold one voltmeter probe to one of the wire terminals, then touch and hold the other probe to the other wire. 5.
