Installation Procedure of Horizontal Concealed Fan Coil Unit

Step 1: On-site Inspection and Preparation

Check the ceiling installation space, unit model and accessories for completeness. Confirm water pipe, circuit and ceiling structure meet installation requirements, and clean the construction site.

Step 2: Hanger and Bracket Installation

Install galvanized hanging brackets according to the reserved position. Level and fix the brackets firmly to ensure they can bear the full weight of the unit and avoid shaking.

Step 3: Unit Hoisting and Positioning

Lift the fan coil unit stably onto the brackets. Adjust the unit level and drainage slope strictly to guarantee smooth condensate water discharge without water accumulation.

Step 4: Water Pipe Connection

Connect the chilled water and hot water pipelines with standard fittings. Install sealing gaskets to prevent water leakage and fix the pipes with damping measures to reduce vibration noise.

Step 5: Condensate Pipe Installation

Lay the condensate drainage pipe with a reasonable slope. Conduct a water filling test to check unobstructed drainage, and seal pipe joints thoroughly to avoid dripping and water leakage.

Step 6: Electrical Wiring Connection

Connect power lines and control lines in accordance with electrical specifications. Ensure firm wiring, correct phase sequence and reliable grounding to prevent electrical faults and safety hazards.

Step 7: Air Duct and Outlet Connection

Connect the unit air inlet and outlet with flexible air ducts. Seal the duct joints tightly to prevent air leakage and ensure uniform air supply and stable operation efficiency.

Step 8: Debugging and Operation Test

Turn on the power and start the unit for trial operation. Check fan running status, temperature adjustment effect, water tightness and noise condition to ensure no abnormal faults.

Step 9: Ceiling Sealing and Completion

After successful debugging, finish ceiling decoration and sealing. Clean the unit and construction site, and complete the installation acceptance and handover work.
