Installation and finishing

1.1 General information

	Warning! Risk of electric shock if touching the components! The unit operates with a 230 V AC voltage.
	Warning! Risk of electrical shock! Electrical installation and service behind secured 230 V AC covers must be carried out under the supervision of a qualified electrician.
	Warning! Uponor system power supply: 230 V AC, 50 Hz. In case of emergency, immediately disconnect the power.
	Warning! Prior to any work on the controller or the components connected to it, switch off the controller according to the regulations.
	Warning! The fittings are under pressure. Escaping pressurized media can cause serious injury such as scalding or eye damage. Depressurise the system before performing any installation work. For retrofits to an existing system: Drain the system or close the supply lines of the section and depressurise it.
	Warning! Risk of injury due to the heavy weight of the unit: Do not perform the installation alone. Always wear safety shoes during the assembly. The unit can be of considerable weight, depending on the configuration. If the station falls over, this could lead to injuries, particularly to the feet.
	Caution! Leaks in the unit may occur during transport or installation. Check the nuts to ensure that they are properly tightened before the connection to avoid property damages.

Before installing the heat interface unit ensure that:

• the primary pipes are laid in the building site.
• the primary pipe installation is flushed and checked for leaks.
• the power and ground cables are routed to the installation site.
• the unit can be installed in a dry and frost-free room with an ambient temperature lower than +40 °C.
• the unit can be installed upright (not inclined, upside down or lying down).
• the unit is always easy to access even after the assembly.
