Conair MPW Quarterly every 3 months, Annually every 12 months, Preventative Maintenance Schedule

●Quarterly (every 3 months)

❒Inspect power cords, wires and electrical connections.

Check for loose or frayed wires, burned contacts, and signs of overheated wires. Check exterior power cords to the main power source and from the electrical box to the pump and heating elements. Check the ground wire and thermocouple connections. Replace any wire that appears damaged or has worn or cracked insulation.

●Annually (every 12 months)

❒Test and calibrate the unit’s control systems. The chiller’s Test Mode checks the operation

of displays, control buttons, inputs and outputs. You can also calibrate the supply and return thermocouples.

See PERFORMING SYSTEM TESTS in this section.

❒Clean all surfaces that come in contact with water. Minerals and other water contaminants cause heat- transfer surface fouling and decrease performance, especially in the water-cooled chiller’s condenser. Clean all water-cooled condenser surfaces. The refrigerant side does not foul because the refrigerant acts as a solvent and operates in a closed filter cycle. See CLEANING

EVAPORATORS AND CONDENSERS in this section.
