WeatherMaker® Standard Efficiency Single-Packaged Rooftop Units 50KC: Monthly Maintenance

4 steps
This procedure is for the monthly maintenance of your unit. It focuses on air filters and screens, re-installing the access panel and outside air hood.
  • Air Filters and Screens

  • Each unit is equipped with return air filters. If the unit has an economizer, it will also have an outside air screen. If a manual outside air damper is added, it will also have an inlet air screen

  • Each of these filters and screens will need to be periodically replaced or cleaned.

  • ! CAUTION

  • EQUIPMENT DAMAGE HAZARD

  • Failure to follow this CAUTION can result in premature wear and damage to equipment

  • DO NOT OPERATE THE UNIT WITHOUT THE RETURN AIR FILTERS IN PLACE.

  • Dirt and debris can collect on heat exchangers and coils possibly resulting in a small fire. Dirt buildup on components can cause excessive current used resulting in motor failure.

  • Return air filters are disposable fiberglass filters. Access to the filters is through the lift-out filter access panel located on the rear side of the unit, above the indoor coil access panel. See Fig. 2.

  • Removing the Return Air Filters

  • Re-Installing the Access Panel

  • Outside Air Hood

  • Outside air hood inlet screens are permanent aluminum-mesh type filters.

  • Check these for cleanliness.
