New air handling units control switch check: Control Panel is more sophisticated electrical components, long-term use due to electrostatic adsorption reason easily lead to accumulation of dust or moisture control panel malfunction or damage to components, the use of the inconvenience. Recommendations made by the professionals at regular intervals (six months) check for new air control system HTFC-11 two-speed exhaust air box, and timely maintenance. New air duct seal check long-term use by the new wind ventilators shock and other reasons easily lead to new connections cracking duct leakage and other phenomena, use effect is reduced. We recommend periodic inspection by a professional duct connections, timely repair, improvement. Test material into the plant before: a key component test: 1. Steel fixed hot-rolled steel is used in high-quality, must provide quality inspection report; 2. Storage shall be carried out before the motor noise, vibration, current test, should meet international and business requirements; 3. Impeller assembly before passing first static balance checking and adjustment HTFC-1 exhaust air box, the impeller static balance to meet the requirements of international and corporate centrifugal wind chassis, and then on the balancing machine balancing test and adjust the impeller, the impeller moving balance to meet the international and business requirements, you can not adjust the impeller must be made scrap.
