MAINTENANCE & TROUBLESHOOTING CLEANING YOUR COILS
As often as you feel necessary for system performance. (At least once a month)
Air- Spray your side vents from overspray and debris with compressed air to remove excess debris.
If you are experiencing your system not cooling as you think it should, take a few minutes to clean your front and rear coils! It is beneficial to the life and performance of the system.
IS IT FEASIBLE TO RUN the AC COMPARTMENT WHEN IT’S COLD OUTSIDE?
The Tennessee Chill Box is cooled by a coolant known as 410A which contains lubricants. As the outdoor temp decreases, the viscosity increases creating the slow flow of the lubricant. When the internal pressure drops, the system will attempt to work harder to pump the coolant.
The refrigerant in the Chill Box will be at the freezing point or below, that will in turn lead to a build -up on the evaporator coils. Constant freezing and thawing of the coils will soon lead to failure of the unit displaying visible ice build -up on the copper lines and condensing coils. The more ice build- up, the more restricted the airflow, which could cause the unit to disperse warm air at the manifold or cause the unit to shut down.
At temperatures below or around 68F, the compressor may start to make strange noises. This is caused by the refrigerant entering the compressor as a liquid rather than vapors. Our system is designed to run on refrigerant vapor which is compressible, liquid is not. If the AC compartment of the system is turned on and is run below temperatures that the Chill Box recognizes as less than compatible, you will notice freeze up on the coils. Please use only the Fresh Air upper chamber on COOLER days to avoid damage to your system as well as COIL freeze up.
