HEF2 Series MANUAL
108
To ensure proper operation in accordance with the health standard VDI6022, maintenance should be
performed regularly as directed, and it is also necessary to keep a maintenance record.
If there is a fan section before the HEF2E, we recommend an air alignment section.
HEF2 SERIES WITH EXTERIOR AIR OR INSTALLED IN AN AHU OUTDOORS
All units using the HEF2 Series with exterior air must stop the pump and drain the water tank in the event of
preheater faults. Units for adiabatic cooling of the return air must drain the water tank water during the winter.
OPERATIONAL PERFORMANCE CONTROL
Humidifiers work with excess panel irrigation. If evaporative performance is to be regulated, this is not done
by controlling the quantity of irrigation water but rather:
•
Preferably, on the operative front surface, regulating the number of cassettes in operation, the HEF2
Series Fisair can be equipped with the necessary components for an external stage control or they can
also include the Fisair step control.
•
Alternatively, by controlling irrigation operation times, so the humidity/temperature regulator acts on the
pump working time.
