5. DISTRIBUTION SYSTEM INSTALLATION
5.1 Blower unit installation
The humiFog Direct system works by connecting the cabinet to a
number of blower units installed directly in the room to be humidifi ed
and/or cooled.
The following simple rules must be kept in mind when installing the
blower units:
•
the minimum fl ow-rate that can be atomised in the room is 8 l/h
(irrespective of the size of the pump). The minimum number of blower
units must therefore be defi ned based on the number and size of the
chosen nozzles.
The maximum numbers of blower units that can be connected to a
cabinet are:
•
12 blower units with 2 nozzles
•
6 blower units with 4 nozzles
•
3 blower units with 8 nozzles
The blower units must be suitably positioned so as to allow complete
absorption of the sprayed water. Consequently it is recommended to
install the blowers a due distance apart, at a suffi
cient height from the
fl oor and with free space at the front without obstacles.
Do not install the head units in recesses, closed corridors or behind curtains,
as this would hinder the uniform diff usion of humidifi ed air. At the fan heads
the air is cooler and more humid and the noise emission of nozzles and fans
must be taken into consideration. Position the heads so as not to cause
discomfort to the occupants of the room. Do not install in areas where the air
is contaminated, particularly by microorganisms or allergens.
The blower units can be mounted either on the wall or on the ceiling.
For a correct installation, see the example or contact Carel for diff erent
temperature and humidity conditions.

Fuses F1, F2, F3*, F4* are positioned on the fuse holders (Fig.4.i).
Fuses F3, F5*, F6* are positioned on the upper surface of the respective
transformers (components no. 17 in the fi gure in para. "Structure").
* indicates the fuse rating of the dual zone pumping station.

4.4 Changing the oil cap
During installation, before starting the unit, remember to replace the red
oil cap (A) on the pump with the yellow one (B) supplied. The red cap is
closed and is only used for transport. The yellow cap has a vent opening
and is used for normal operation of the system. The yellow cap is supplied
inside the cabinet, tied to the high pressure gauge (see the image below).
