5. Evaporator Coils: No Rinse Required.
6. In food processing areas: Remove or protect all food and packaging materials. Rinse with potable water after use if contact with food or packaging materials is expected.
7. All Done!

Apply Viper Heavy Duty through the Viper Foam Gun or manually dilute the product and use with any conventional spray equipment. Applying through the gun allows for better coverage and contact time. Condenser coils require only a light water rinse. Evaporator coils  do  not  need  to  be  rinsed  as  long  as  there  is  adequate condensate production.

Viper Heavy Duty is a concentrated version of Viper Coil Cleaner. Viper Heavy Duty has a superior cleaning performance on organic contaminants such as natural fats and grime, compared with acid or alkaline cleaners. Viper Heavy Duty is safe for technicians, equipment and the environment, including food processing areas. It achieves high quality results without hazardous ingredients. It is non-toxic, non-irritating, odourless, neutral pH, biodegradable, does not emit hazardous odours or fumes so no masks or ventilators are needed. Viper Heavy Duty is food industry compliant, with NSF certification for all food processing areas. It is safe to use anywhere, even in hospitals and restaurants.

• The only difference between an alkaline product (Viper Brite) and Viper Heavy Duty is that Viper Heavy Duty will not lift oxidisation and hard carbon deposits.
  
  
• The chemical compound in Viper Heavy Duty effectively destroys heavy organic contaminants such as mould, dirt and natural fats.
  
  
• Viper Heavy Duty is safe to use on all surfaces, plastics and rubbers.
  
  
• Viper Heavy Duty diluted to 50:1 is a brilliant spray and wipe.
  
  
• The cleaning agents in Viper Heavy Duty are optimised for superior cleaning and degreasing. Never mix Viper Heavy Duty with other cleaning compounds. This will block the performance of the advanced detergents in Viper Heavy Duty.
