▪ Connecting the water connections.
Note: When equipped with an electric actuator, the unit is part of a system. The needed wires are connected during
the installation phase of the system.
4.1.3 Installation requirements
When planning the orientation of the Halton Rex Expander chilled beam, the location of the supply air and water
circuit connections must be taken into account. The supply air spigot can be at either side of the unit or at the same
end with the water connections. The location can be easily changed on site, if needed.
The location of the actuator of the HAQ control (optional) must also be taken into account to ensure access to the
actuator. The actuator is located in the middle of the left side of the unit.
The Halton Rex Expander chilled beam can be attached directly to the ceiling surface (H = 220 mm) or suspended
using threaded drop rods (8 mm). The brackets for ceiling installation are located at the sides of the unit.

Because there are no moving parts in the Halton Rex Expander chilled beam, no anti-vibration protection is needed
when installing the unit or when connecting the unit to supply air or water circuit connections.
It is recommended that the main pipelines of the cooling and heating water circuits are installed above the level of
the heat exchanger to enable venting of the pipework.
The maximum operating pressure for chilled/hot water pipework is 1.0 MPa.
