1 Compressor Medo Some STATIM L / 5000 / 5000S units have been manufactured with an additional bacteria-retentive air filter. Units without the bacteria-retentive air filter draw air through the cylindrical air filter at the back of the unit, into the compressor and into the steam generator via the check valve. Units with the bacteria-retentive air filter draw air through the cylindrical air filter at the back of the unit, into the compressor, through the bacteriaretentive air filter and into the steam generator via the check valve. Please note the differences in disassembly and assembly procedures. To remove the cover, see Statim L / 5000 / 5000S Cover Removal and Replacement. Removing and Inspecting the Compressor To remove and inspect the compressor, follow these steps (see Figure 1): 1. Turn the power switch OFF, and unplug the unit. With the cylindrical air filter only : 2A. Locate the rubber tube (1) which extends from the compressor (2) to the steam generator check valve (3). Disconnect the compression nut (4) securing the tube to the compressor and remove the tube from the fitting. With the additional bacteria-retentive filter : 2B. Locate the rubber tube (5) which extends from the compressor (2) to the input side of the bacteria-retentive filter (6). Disconnect the compression nut (4) securing the tube to the compressor and remove the tube from the fitting. 3. Locate the transparent rubber tube (7) which extends from the compressor intake fitting to the air fitting (8). Cut the cable tie (9) securing the tube to the compressor and remove the tube from the fitting. 4. Remove the four screws (10) that attach the compressor bracket (11) to the chassis (12). Retain the screws. Some compressor brackets may appear slightly different then the bracket you are servicing. Use the bracket that accompanies the replacement compressor. 5. Disconnect the leads from Controller Board (13) terminal block positions J1-9 LINE and J1-10 NEUTRAL, and carefully cut the cable ties (14) securing the compressor leads (15). 1

3 Compressor Medo Replacing the Compressor SciCan recommends that the check valve be replaced when the compressor is replaced. See Steam Generator Removal, Cleaning and Replacement, the Steam Generator Check Valve. To replace the compressor, follow these steps (see Figures 1 and 2): 1. Connect the ground wire (18) to the compressor body. 2. Position the compressor / bracket assembly (11) in the chassis (12). Route the compressor leads (15) with the bundle of wires leading to the Controller Board (13). Connect the black lead to Controller Board terminal block position J1-9 LINE and the white wire to terminal block position J1-10 NEUTRAL. 3. Bundle the wires together and secure them using nylon cable ties (14) every 2-3 inches. 4. Reinstall the four screws (10) retained during disassembly. Do not crush wires or tubes. 5. Reconnect the pressure transducer connector (16) to the transducer (17), if present. 6. Connect the transparent rubber tube (8) which extends from the compressor intake fitting to the air filter fitting (6). Secure the tube using a nylon cable tie (9). With the cylindrical air filter only (see Figure 1): 7A. Connect the rubber tube (1) which extends from the top of the compressor (2) to the steam generator check valve (3). Secure the tube using the plastic compression nut (4). With the additional bacteria-retentive filter (see Figure 2) : 7B. Connect the rubber tube (5) which extends from the top of the compressor (2) to the input side of the bacteria-retentive filter (6). Secure the tube at the compressor end with the plastic compression nut (4). 8. Test the compressor by activating the compressor switch on the Control Box. See Required Information and Tools, the Control Box. 9. A dielectric strength test (Hi - Pot) and a protective bonding impedance test (ground continuity) must be performed on the STATIM L / 5000 / 5000S unit. See Required Information and Tools. 10. Reinstall the cover. See STATIM L / 5000 / 5000S Cover Removal and Replacement. 3

5 All STATIM L / 5000 / 5000S units with a have been manufactured with the bacteria-retentive air filter. The previous units with the Medo Compressor draw air through the cylindrical air filter at the back of the unit, into the compressor and through the bacteria-retentive air filter into the steam generator via the check valve. The draws air directly into the compressor, then pushes the air through the bacteria retentive filter and check valve into the steam generator. Replacing the Medo Compressor with the (see Figure 3, 4): To remove the Medo Compressor, follow these steps: (see Figure 1 and 2): 1. Turn the power switch OFF, and unplug the unit. 2. Disconnect the compression nut (4) securing the rubber tube (5) to the Medo compressor and remove the tube from the fitting. 3. Locate transparent rubber tube (7), which extends from the Medo compressor intake fitting to the air fitting (8). Cut the cable ties (9) from both ends and remove the tube from the unit. 4. Remove the four screws (10) that attach the compressor bracket (11) to the chassis (12). Retain the screws. 5. Disconnect the leads from Controller Board (13) terminal block positions J1-9 LINE and J1-10 NEUTRAL, and carefully cut the cable ties (14) securing the compressor Leads (15). 6. If present, disconnect the transducer connector (16) from the transducer (17). 7. Disconnect the ground wire (18) from the compressor body and remove the compressor from the unit. The cylindrical air filter and air filter fitting should stay in place. In the new version the cylindrical air filter will not be installed any more. There will be no opening in the chassis for the air filter. 5

6 To replace the, follow these steps (see Figure 3 and 4): 1. Connect the ground wire (18) to the compresser body. 2. Position the compressor / bracket assembly (11) in the chassis (12). Route the compressor leads (15) with the bundle of wires leading to the Controller Board (13). Connect the black lead to Controller Board terminal block position J1-9 LINE and the white wire to terminal block position J1-10 NEUTRAL. 3. Bundle the wires together and secure them using nylon cable ties (14) every 2-3 inches. 4. Reinstall the four screws (10) retained during disassembly. Do not crush wires or tubes. 5. Reconnect the pressure transducer connector (16) to the transducer (17), if present. 6. Connect the rubber tube (5), which extends from the top of the compressor (2) to the input side of the bacteria-retentive filter (6). Secure the tube at the compressor end with the plastic cable tie (g). 7. Test the compressor by activating the compressor switch on the Control Box. See Required Information and Tools, the Control Box. 8. A dielectric strength test (Hi - Pot) and a protective bonding impedance test (ground continuity) must be performed on the STATIM L / 5000 / 5000S unit. See Required Information and Tools. 9.
