- Only qualified personnel is allowed to install or maintain this product
- Disconnect the power when dismounting the coil
- Avoid direct exposure to alkaline conditions, use in neutral conditions is recommended
- Ensure that the O-ring is in place on the valve
- If the coil is used as independently mounted control, the end-user shall use a plastic cable
gland with strain relief
Special note for R290:
The 9 mm coil (IP65/67) is validated in accordance to ISO 5149, IEC 60335 (ref. IEC/EN 60079-
15). Ignition risk is evaluated in accordance to ISO 5149 and IEC 60335 (ref. IEC/EN 60079-15).
Please make sure that there is no spark, arc on the spade connection during the application.
Always Install a fuse ahead of the coil: rated current: two times of rated current, time lag:
medium, to avoid short circuit.
The coil used in an area of not more than pollution degree 2.
Follow the installation guide to mount the coil correctly, and apply o-ring for sealing to
prevent moisture penetrating inside the coil.
Safety note:
The 9 mm coil (IP65/67) can be applied on systems with R290 as the working fluid.
For countries where safety standards are not an indispensable part of the safety system
Danfoss recommends the installer gets a third party approval of any system containing
flammable refrigerant.
Please follow specific selection criteria stated in the datasheet for these particular
refrigerants.
Note that 9 mm coil (IP65/67) has NOT been verified ATEX or IECEx or IEC 60079 series zone
2 compliant. The product is only validated for systems in compliance with ISO5149, IEC
60335 (ref. IEC/EN 60079-15). It is the responsibility of the user to verify such compliance.
Improper use can cause explosion, fire, leakage potentially causing death, personal injury,
or damage to property.
