Unified Brands strongly suggests a preventive maintenance program which would
include the following monthly procedures:
If a failure of the equipment is a direct result of any of the Preventative Maintenance
guidelines being neglected, the repairs and parts replacements will not be covered
under warranty.
It is recommended that the customer contact the local Authorized Service Agent to
provide a quote to perform periodic Preventative Maintenance.
MONTHLY PROCEDURES
1. Cleaning of all condenser coils. Condenser coils are a critical component in the
life of the compressor and must remain clean to assure proper air flow and heat
transfer. Failure to maintain this heat transfer will affect unit performance and
eventually destroy the compressor. Clean the condenser coils with coil cleaner
and/or a vacuum cleaner and brush. NOTE: Brush coil in direction of fins, normally
vertically as to not damage or restrict air from passing through condenser.
2. Clean fan blades on the condensing unit.
3. Clean and disinfect drain lines with a solution of warm water and mild
detergent.
4. Check silicone seal around drop in flange for peeling and cracks. Reapply with
food grade silicone as necessary.
