HYDRAULIC CONNECTIONS

The cooling water inlet and outlet (water cooled models) is made by hoses situated in the lower part of the unit
with female union nuts on their ends.
Passage provided on the right or left side.
Condensate drain: the hose (26 x 32) coiled in the lower part of the unit must be brought out through the hole
3 page 8.

SAFETY DRAIN.

The sealed bottom of the indoor unit which collects condensate or abnormal overflow is equipped with a right or
left lateral outlet pipe 22mm outer diameter.
The condensate drain pipe must have a minimum slope of 2,5 cm/m in the flow direction.
In case of connection to the sewer it is necessary to provide a trap on the drain pipe.
Thermical insulation (6 mm mini) must be provided when necessary (risk of freezing or condensation).

ELECTRICAL CONNECTIONS

The electrical box is situated behind the lower front pane.
General supply through the power terminals situated on the left in the electric box, behind the plastic protection
cover.
CAUTION
In the case of a casing heater it must be started according to the compressor is located: 2 hours before starting of
the unit for a temperature of 10°C and 4 hours before starting for a temperature of 0°C.
The outdoor units are supplied wired for a three-phase 400VAC 3-phase + Earth power supply voltage.
