Insulation
1. The insulation design and materials should be complying with local and national codes and regulations.
2. Chilled water pipes and all parts on the pipes should be insulated.
3. It is also necessary to insulate the air duct.
Air Duct Connection
1. Circulatory air pressure drop should be within External Static Pressure.
2. Galvanized steel air ducts are suitable.
3. Make sure there is no leak of air.
4. Air duct should be fire-proof, refer to concerned country national and local regulations.
Piping Connections
1. Using suitable fittings as water pipe connections with reference to the outline and dimensions.
2. The water inlet is on the bottom while outlet on top.
3. The connection must be concealed with rubberized fabric to avoid leakage.
4. Drain pipe can be PVC or steel.
5. Tightening torque should not be too high when connecting water pipes, in order to avoid brass deformation or water-
leakage by torsion split.
6. The suggested slope of the drain pipe is at least 1:50.
Caution
When connecting pipe to fan coil unit, do not bend or reposition the coil header for alignment
purposes. This could cause a tubing fracture resulting in a water leak when water pressure is
applied to the system.
