OPERATING RANGE
Maximum water inlet temperature:
Maximum operating pressure:
Minimum operating pressure:
Minimum average water temperature
The above limits refer to operation with the fan running at minimum speed.
In case of a prolonged period with the fan switched off and cold water running in the coil, condensate may form outside the unit.
An accessory three-way valve should therefore be installed.
MINIMUM AVERAGE WATER TEMPERATURE
Wet bulb room temperature °C
INSTALLATION: CONDENSATE DRAIN
Pipes MIN Φ 20mm
After work check the condensate drains cor-
rectly by pouring some water into the drip tray

▪ The water pipes should be suitably insulated to prevent
them from dripping in the cooling mode.
▪ The condensate drain network must be suitably sized and
the pipes positioned so as to assure a sufficient slope (min.
3%). To assure a regular flow, there must be no upward
sections or bottlenecks.
▪ The condensate drain should be fitted with a trap.
▪ Connect the condensate drain to a storm sewer.
▪ Do not use washing or sewage water drains as this may
cause unpleasant odours in the rooms if the water in the
trap evaporates.
