7.9 DX COIL Manufacturing
・ DX COIL & Pipework Design Pressure:
・ DX COIL & Pipework Burst Pressure (withstand):
DX COIL Contamination:
・ Ensure the DX COIL is cleaned, using detergent, after manufacture to remove contaminants from the coil
・ Do not use chlorinated detergent during the cleaning process
・ Do not leave flux on or inside the DX COIL
DX COIL & Pipework Contamination (Allowable Limits):Residual water amount
・ DX COIL contaminants must be equal to or less than the values shown above. The allowable contaminant
levels shown assumes Ø9.52mm copper tube has been used for the manufacture of the DX COIL

Installation Angle
Avoid Direct Sunlight.
DO NOT install outside.
・Avoid locations exposed to steam or oil vapours.
・Avoid locations where combustible gas may leak, settle or be generated.
・Avoid installation near machines emitting high-frequency waves.
・Avoid places where acidic solutions are frequently used.
・Avoid places where sulphur based or other sprays are frequently used.
・Avoid places where vibrations may occur.
・When installing the Dx-valve kit and the Dx-coil controller into the Air handling unit,
do not install it where it is exposed to the cooled air of the secondary side of the heat
exchanger.
・Do not install in locations where iron or other metal dust is present. If iron or other
metal dust adheres to or collects on the interior of the Dx-coil controller, it may
spontaneously combusted and start a fire.
・Standard Rating ; IP21
To avoid damage; when making holes for cable glands, please first remove the Gland
Plate from the DX Coil CONTROLLER
52°C (or less)
Relative humidity 80% (or less). No dew condensation allowed.
If the DX-Controller is to be installed where dew condensation could form,
locally sourced insulation should be fitted to avoid condensation.
