5. PIPE
CONNECTIONS
5.1. HYDRAULIC
CONNECTIONS
Ensure the water piping, condensate drain and
electrical circuit are already installed.
The selection and sizing of the pipework is the
responsibility of the designer, which must be in
accordance with good practices and applicable
legislation.
Always use a counter-spanner when fixing pipe-
work with a spanner.
It is recommended that pipework is suitably
insulated to prevent condensation in cooling
mode, even if the Omnia UL_R and UL_RI have
a condensate drain tray as standard. Carry out a
leak test of all hydraulic connections.
