Periodic Clean Water Rinse
A periodic clean-water rinse is very beneficial for coils that are used 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 damage to the fin edges. Monthly cleaning, as described below, is recommended.
Routine Cleaning of Evaporator Coil Surfaces
Monthly cleaning with Totaline environmentally sound coil cleaner is essential to extend the life of the coils. This cleaner is available from Carrier Replacement Parts Division (P/N: P902-0301 for a one gallon (3.8L) container, and P/N: P902-0305 for a 5 gallon (18.9L) container). It is recommended that all round tube coils be cleaned as described below. Coil cleaning should be part of the unit’s regularly scheduled maintenance procedures to ensure a long life for the coil. Failure to clean the coils can r
When cleaning the coils, avoid use of the following:
Totaline environmentally sound coil cleaner is a nonflammable, hypo allergenic, non bacterial, 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.
TOTALINE ENVIRONMENTALLY SOUND COIL CLEANER APPLICATION EQUIPMENT:
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 dissim- ilar materials are in contact. If there is dirt below the surface of the coil, use the environmentally balanced coil cleaner.
PERSONAL INJURY HAZARD
Failure to follow this caution can result in severe personal injury and reduced unit performance.
High velocity water from a pressure washer, 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.
High velocity water from a pressure washer can cause severe injury upon contact with exposed bodily tissue. Always direct the water stream away from the body.
