NOTE: Please see the NOVATION Heat Exchanger Condenser Service section for specific information on the NOVATION Heat Exchanger coil.
!CAUTION
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in damage to equipment.
Chemical cleaner should NOT be used on the aluminum NOVATION condenser. Damage to the coil can occur. Only approved cleaner is recommended.
Routine Cleaning of Round−Tube Coil Surfaces
Monthly cleaning with Totaline environmentally sound coil cleaner is essential to extend the life of coils. This cleaner is available from Carrier Replacement parts division as part number
Avoid the use of:
Scoil brighteners

!CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in corrosion and damage to the unit.
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 sound coil cleaner as described above.
!CAUTION
UNIT RELIABILITY HAZARD
Failure to follow this caution may result in 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.
Totaline Environmentally Sound Coil Cleaner Application Instructions
1.Proper eye protection such as safety glasses is recommended during mixing and application.
2.Remove all surface loaded fibers and dirt with a vacuum cleaner as described above.
3.Thoroughly wet finned surfaces with clean water and a low velocity garden hose, being careful not to bend fins.
4.Mix Totaline environmentally sound coil cleaner in a 21/2 gallon garden sprayer according to the instructions included with the cleaner. The optimum solution temperature is 100_F.
NOTE: Do NOT USE water in excess of 130_F, as the enzymatic activity will be destroyed.
5.Thoroughly apply Totaline environmentally sound coil cleaner solution to all coil surfaces including finned area, tube sheets and coil headers.
6.Hold garden sprayer nozzle close to finned areas and apply cleaner with a vertical,
7.Ensure cleaner thoroughly penetrates deep into finned areas.
8.Interior and exterior finned areas must be thoroughly cleaned.
9.Finned surfaces should remain wet with cleaning solution for 10 minutes.
10.Ensure surfaces are not allowed to dry before rinsing. Reapplying cleaner as needed to ensure
11.Thoroughly rinse all surfaces with low velocity clean water using downward rinsing motion of water spray nozzle. Protect fins from damage from the spray nozzle.
