WeatherMaker® Single-Packaged Rooftop Units with EcoBlue™ Technology 48GC: Condenser Coil Maintenance and Cleaning Recommendation

6 steps
This procedure is for the maintenance of your condenser coil and cleaning recommendations of your equipment. The simple routine maintenance as described in this procedure will enhance your air conditioning system’s ability to operate economically and dependably.
  • PERIODIC CLEAN WATER RINSE

  • A periodic clean water rinse is very beneficial for coils that are applied in coastal or industrial environments. However, it is very important that the water rinse is made with a very low velocity water stream to avoid damaging the fin edges. Monthly cleaning as described below is recommended. Rinsing coils in the opposite direction of airflow is recommended.

  • ROUTINE CLEANING OF COIL SURFACES

  • Periodic cleaning with Totaline® environmentally balanced coil cleaner is essential to extend the life of coils. This cleaner is available from Replacement Components Division as part number P902-0301 for a one gallon container, and part number P902-0305 for a 5 gallon container. It is recommended that all coils, including standard aluminum, pre-coated, copper/copper or e-coated coils be cleaned with the Totaline environmentally balanced coil cleaner as described below. Coil cleaning should be part of the u

  • Avoid use of:

  • Totaline environmentally balanced coil cleaner is nonflammable, hypo-allergenic, non-bacterial, and a USDA accepted biodegradable agent that will not harm the coil or surrounding components such as electrical wiring, painted metal surfaces, or insulation. Use of non-recommended coil cleaners is strongly discouraged since coil and unit durability could be affected.

  • One-Row Condenser Coil (48FC 04 units only)

  • Two-Row Condenser Coils (48FC 05-07 units)

  • Clean coil as follows:

  • FIG. 19

  • FIG. 20

  • FIG. 21

  • ! CAUTION

  • UNIT DAMAGE HAZARD

  • Failure to follow this caution may result in reduced unit performance or unit shutdown.

  • High velocity water from a pressure washer or garden hose, or compressed air should never be used to clean a coil. The force of the water or air jet will bend the fin edges and increase airside pressure drop.

  • ! CAUTION

  • UNIT DAMAGE HAZARD

  • Failure to follow this caution may result in accelerated corrosion of unit parts.

  • Harsh chemicals, household bleach or acid or basic cleaners should not be used to clean outdoor or indoor coils of any kind. These cleaners can be very difficult to rinse out of the coil and can accelerate corrosion at the fin/tube interface where dissimilar materials are in contact. If there is dirt below the surface of the coil, use the Totaline environmentally balanced coil cleaner.
