14. PIPE CONNECTIONS
WARNING
Only left hand pipe connections
are possible and the coil cannot
be reversed
.
14.1. 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
pipework with a spanner.
It is recommended that pipework is suitably
insulated to prevent condensation in cooling
mode, even if Omnia UL_R and UL_RI have a
condensate drain tray as standard. Carry out a
leak test of all hydraulic connections.

14.2. CONDENSATE DRAIN
In cooling mode the unit removes humidity
from the internal air. This condensate must be
removed by connecting the unit's condensate
drain outlet to the condensate drain system.
Note:
Before connecting the condensate drain,
pierce the diaphragm of the drain pan, on
the hydraulic connections side, with a suit-
able tool. Seal the drain hole not used.
Connect the drain pan discharge to the conden-
sate drain system with a drain tube. The drain
pan connection is only designed for use with
flexible tubes of adequate internal diameter.
Avoid imposing any loads and do not use for
any other purpose.
The condensate drain system must be ade-
quately sized and the piping arranged to ensure
a sufcient incline along the length (minimum
1%). If connected to the sewerage system it is
recommended that a trap is used to prevent
odours rising into the space.
