Odyssey® Split Systems with Symbio Controls: Annual Maintenance

This annual procedure is for regular coil maintenance, including annual cleaning which enhances the unit’s operating efficiency by minimizing: compressor head pressure and amperage draw; evaporator water carryover; fan brake horsepower, due to increase static pressure losses; airflow reduction.

Odyssey® Split Systems with Symbio Controls: Annual Maintenance

This annual procedure is for regular coil maintenance, including annual cleaning which enhances the unit’s operating efficiency by minimizing: compressor head pressure and amperage draw; evaporator water carryover; fan brake horsepower, due to increase static pressure losses; airflow reduction.

    Annual Maintenance

    Before completing the following checks, turn the unit OFF and lock the main power disconnect switch open.

    ! WARNING

    Hazardous Voltage!

    Failure to disconnect power before servicing could result in death or serious injury. Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Verify that no power is present with a voltmeter.

    Filters

    Inspect the return air filters. Clean or replace them if necessary. Refer to the unit Service Facts for filter information.

    Condensate Overflow Switch

    During maintenance, the switch float (black ring) must be checked to ensure free movement up and down.

    Cooling Season

    With the unit running, check and record the following:

    Record this data on an “operator’s maintenance log” like the one shown in Sample maintenance log table in Final Process Section. If the operating pressures indicate a refrigerant shortage, measure the system superheat and system subcooling. For guidelines, refer to “Compressor Start-Up,” p. 34.

    Important: Do not release refrigerant to the atmosphere! If adding or removing refrigerant is required, the service technician must comply with all federal, state and local laws. Refer to general service bulletin MSCU-SB-1 (latest edition).

    Coil Cleaning

    Regular coil maintenance, including annual cleaning enhances the unit’s operating efficiency by minimizing the following:

    Microchannel (MCHE) Coils

    NOTICE:

    Coil Damage!

    Failure to follow instructions below could result in coil damage. DO NOT use any detergents with microchannel condenser coils. Use pressurized water or air ONLY, with pressure no greater than 600psi.

    Due to the soft material and thin walls of the MCHE coils, the traditional field maintenance method recommended for Round Tube Plate Fin (RTPF) coils does not apply to microchannel coils. Moreover, chemical cleaners are a risk factor to MCHE due to the material of the coil. The manufacturer does not recommend the use of chemical cleaners to clean microchannel coils. Using chemical cleaners could lead to warranty claims being further evaluated for validity and failure analysis
