PIPE CONNECTIONS
WARNING
Only left hand pipe connections
are possible and the coil cannot
be reversed
.
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.

CONDENSATE DRAIN
In cooling mode the unit removes humidity from
the internal air. This condensate must be re-
moved by connec ng the unit's condensate drain
outlet to the condensate drain system.
Note:
Before connec ng the condensate drain, pierce
the diaphragm of the drain pan, on the hydrau-
lic connec ons side, with a suitable 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 connec on is only designed for use with
fl exible tubes of adequate internal diameter.
Avoid imposing any loads and do not use for any
other purpose.
The condensate drain system must be adequately
sized and the piping arranged to ensure a suf-
fi cient incline along the length (minimum 1%). If
connected to the sewerage system it is recom-
mended that a trap is used to prevent odours
rising into the space.
