Safety requirements
1. KP pressure switches shall only be employed in the units/systems which comply with the requirements for charge limits and
requirements for avoiding ignition sources of IEC 60335-2-24, IEC 60335-2-40, IEC 60335-2-89, ISO 5149, EN378-1 or equivalent.
2. Applying the overload on the KPs must be prevented. If by any chance it was damaged, the system / unit shall be stopped and
KP shall be replaced as necessary.
3. Electrostatic discharge protection and Electrical leakage protection shall be surely implemented by grounding or other
measures.
4. Only trained personnel are authorized to handle ammable refrigerants systems and may do the installation, maintenance and
exchange of the switch by using appropriate tools.
5. It is recommended to regularly check the function of KP switch.
6. The KP pressure switches shall be used as built-in devices that cannot be accessible from outside and protected against
mechanical impact.
7. The KPs shall be installed in water free environment. In addition, protection of the KP switches against corrosion shall be taken
into consideration when using them in corrosive environment.
8. Cables shall not be in contact with sharp edges. The cables shall be connected with adequate stress relieve in order to prevent
that pulling forces can be carried thorough the cable to the terminal.
9. In the event of pressure pulsation in the system, where switch is connected, these must be eectively dumped to prevent
failure of the bellows. The cycle frequency of KP switch shall be kept as low as possible.
10. The KP switches shall not be installed in places where high level of vibration is present.
Disclaimer
The user is responsible for ensuring that third parties also comply with this Notice, e.g. in case that the KP switches are supplied to
third parties, and e.g. that all installation guides are available with the KP switches during installation. It is required that all
conditions of this guide are being met and secured when using KP pressure switches.
Danfoss shall not be responsible for any kind of direct and indirect or consequential damage or loss, including, but not limited to,
loss of property, production, loss of prot, human injury arising out of the explosion or re caused by the ammable nature of
refrigerant.
