Clean coil as follows:
1.Turn off unit power, tag disconnect.
2.Remove top panel screws on outdoor coil end of unit.
3.Remove coil corner post. To hold top panel open, place coil corner post between top panel and center post.
4.Remove screws securing coil to compressor plate and compressor access panel.
5.Use a water hose or other suitable equipment to flush down the coil to remove dirt and debris. Clean the outer surfaces with a stiff brush in the normal manner.
6.Remove the coil corner post from between the top panel and center post. Reinstall the coil corner post and replace all screws.
Totaline Environmentally Sound Coil Cleaner Application Equipment

•Water rinse with low velocity spray nozzle
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 clean- ers 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 inter- face where dissimilar materials are in contact. If there is dirt below the surface of the coil, use the Totaline environmen- tally sound coil cleaner as described above.
UNIT DAMAGE 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 in- crease airside pressure drop.
Totaline Environmentally Sound Coil Cleaner Application Instructions
1.Proper eye protection such as safety glasses is recom- mended 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 spryer according to the instructions includ- ed with the cleaner. The optimum solution temperature is 100°F (38°C).
NOTE: Do NOT USE water in excess of 130°F (54°C), 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 ap- ply cleaner with a vertical,
7.Ensure cleaner thoroughly penetrates deep into finned ar- eas.
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. Re- apply cleaner as needed to ensure
11.Thoroughly rinse all surfaces with low velocity clean wa- ter using downward rinsing motion of water spray nozzle. Protect fins from damage from the spray nozzle.
Service Parts
Listings of service parts for all units are available from the Re- placement Components Division’s Electronic Parts Informa- tion Catalog (EPIC). EPIC is available at Totaline stores, dis- tributor and service office parts departments and
When entering EPIC, the full unit model number is required. The model number includes the Design Revision reference val- ue (see Fig. 2, Position 13). The unit model number is available from the unit’s information data plate. (Do not use the “catalog number” when using EPIC. The “catalog number” suppresses the Design Revision value; failure to include Design Revision value may cause an incorrect unit parts list to be displayed.) When using EPIC, enter first four digits of the model number only. Find appropriate model from sales packages listed. Be sure to choose correct voltage and Design Revision.
EPIC is a product of RCD. To comment of the EPIC program, use the “Comment” button inside the EPIC program.
