PRECAUTIONS FOR OPERATION OF HUMIDIFIERS TYPE ENS
Precautions for Operation of Humidifiers Type ENS
1)
Install the humidifier in horizontal position and ensure that the gene-
rated mist will be absorbed in an efficient manner by the airflow blown out
by the fan of the air conditioning unit. Air speed should be 1.5 to 3.0 m/s.
Carefully choose the location of the humidifier in those cases, where a
special air conditioning unit is used, such as e.g. a compact air conditioning
unit, that takes in the air through the humidifier.
2)
Current supply should be dimensioned as to ensure that the humidi-
fier will be supplied with power current only if the fan of the air conditioning
unit is set to operation.
3)
A hygrostat or humidity sensor should be activated if the air humidity
falls below the setpoint.
4)
Should more than one humidifier be controlled by one hygrostat only,
multiplication should be provided by means of several relays.
5)
The water used must be fully demineralized. Install a valve in the
supply line for maintenance and control purposes.
6)
If the humidifier is intended for installation in air ducts, the airflow rate
should be between 1.5 and 3 m/s; additionally, a stainless steel drain pan
(1.4571) has to be provided.
7)
Should the air conditioned room be supplied at the same time with
humidity during the cooling procedure, install the humidifier behind the
cooling coil in order to prevent any loss in the humidifier output.
8)
Should the humidifier be operated in an area where temperature may
all below the freezing point (0°C), insulate and protect the water supply
lines and the water tank against frost damage.
