The reason the whole heat exchanger failure in use: 1, the noise becomes big reason: Fixed loose fan impeller rotor is not stable, the outlet is blocked. Solution: contact with the manufacturers, so the manufacturers technical guidance. 2, the wind becomes small reasons: new internal air ventilator filter or clogged heat exchanger portion of the total heat exchanger, causing wind becomes small. Solution: for cleaning and maintenance. 3, the machine is not running Cause: The motor burned most likely solution: contact the manufacturer for help. 4, heat recovery weakened reasons: Because the heat exchanging body covered with dust, resulting in lower thermal conductivity. Solution: heat exchangers for cleaning and maintenance. Total heat exchanger technology: specialized air filtration and purification filters to ensure clean, fresh air into the room. If the air is fresh air or fresh air input not have special requirements, you can filter equipment with high performance.
