Product Features

　1. Outstanding quality and stable performance
　　 The surface coolers of fan coils are made of high quality copper tubes, aluminum foil and high strength galvanized steel sheets that are closely linked through tube deflation to achieve best heat transfer efficiency.

　2. Stable running and low noise
　　 Thanks to the utilization of 3-speed motors and centrifugal wind wheels, the noise level is greatly reduced and the wind output capacity is increased. Thermal insulation and vibration reduction materials are used in every connection spot to create you a quite and comfortable space.

　3. Advanced technique, safe and reliable in use
　　The company has a complete line of high automation equipment to produce fan coils of high quality and each coil produced is strictly tested to meet the requirement of high strength and impact resistance. Thus, the use safety can be relied.

　4. 3-level speed regulation
　　The speed level can be adjusted at user's will to satisfy the needs for different wind volume.

　5. Diversified types, easy to install
　　 The units are light and handy, only 23 cm thick. Ultra-thin type is only 20 cm thick. The water inlet and outlet tubes and the electric lines are easy to connect and the water flow directions and wind directions can be altered according to the site needs.　Various installation types available to meet your decoration needs.

　6. Complete selection of types
　　The coil range comes available in 10 types ranging from FP3.5 to FP20 for different air conditioned areas. Besides, ultra-thin coil is available for extremely small living space.

Instruction to Use:
 

Please note that all fan coils shall be installed, utilized and maintained by or under the instructions of professionals so as to avoid hurts or damages to operators and equipment.

1. Check before the installation whether the unit is kept in good condition and with complete components, whether the joints are fastened firmly. Wind wheel shall be strictly protected from striking or impact during the transportation.

2. The unit shall be installed accurately in horizontal direction so as the condensed water can be drained smoothly.

3. Please use soft pipes to connect unit and water supply system, and the copper joint shall be fastened solidly with spanner to protect the unit from possible damages.

4. All water pipes shall be wrapped with thermal insulation materials.

5. The power source used is single phase, 220±10V and 50±5HZ. Be noted that the phase wire shall be introduced into the motor from the beginning end and all joints shall be connected in maximum security to avoid potential dangers. Units in different types shall not share a same control switch.

6. The vent valve mounted above the joint of return pipes shall be opened before running and closed after the water tank is imbued.

7. The working temperature of unit is 600℃～650℃ and the flow speed is 0.5～2.0m/s(suggested to select within the range of 0.5～1.0m/s)

8. The heat exchanger shall be cleaned from time to time to maintain a good heat transfer performance, and the filter net shall be cleaned regularly to keep a smooth air return.
