Duct connection: Stainless steel flexible fittings with a length of ≤ 1.5 meters are used to avoid wind resistance and vibration transmission. Drainage slope: The slope of the water tray towards the drainage pipe should be ≥ 5 ° to prevent water accumulation.

Key points for installation and maintenance of high static pressure fan coil units

Installation specifications
Duct connection: Stainless steel flexible fittings with a length of ≤ 1.5 meters are used to avoid wind resistance and vibration transmission.
Drainage slope: The slope of the water tray towards the drainage pipe should be ≥ 5 ° to prevent water accumulation.
Electrical safety: The motor must be grounded, and the specifications of the power cord must meet the requirements (such as FP-170 type requiring 4mm ² copper core wire).
Maintenance strategy
Quarterly cleaning: Clean the filter screen and coil fins every quarter to prevent dust accumulation from affecting heat transfer efficiency.
Annual maintenance: Check the fan bearings, motor coils, and drainage pipes annually, replace lubricating oil and aging components.
Fault handling:
Excessive noise: Check the bearing, fan impeller, and pipeline for air accumulation, and exhaust the air through the exhaust valve.
Leakage: Clean the drainage pipe and adjust the slope of the water tray.
Poor cooling effect: Clean the filter screen and coil, check the water supply temperature and flow rate.
