7-7. 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 Ø3/8 in. (Ø9.52 mm) copper tube has been used for the manufacture of the DX COIL

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 ; IP65
To avoid damage; when making holes for cable glands, please fi rst remove the
Gland Plate from the Dx-coil controller
126°F (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 fi tted to avoid condensation.
