First Start-Up; All Models - Mark TA209 Livret Technique

To optimize the system efficiency, consider the following openings for air expulsion:
Guarantee about 0,5 sq.mt of extraction for every 1000 cu.mt. of introduced air (refer to the project
data).
The more dry the external air is, the more cooling capacity could be reached by the system. Your
evaporative cooling system will not operate at maximum efficiency during high humidity days
however it will still reach an efficient cooling level.
In areas with high relative humidity, the evaporative air cooling system must be oversized to
EN
guarantee more air changes, or in other words, it must have higher capacity to compensate the
smaller temperature difference given. In these areas, the maximum cooling effect will be reached by
making sure that there are more air evacuation points than normally used and that the units will be
switched on early in the morning to avoid latent heat growing up inside the space to be cooled. Your
supplier will design your system considering your climatic conditions. During days when the relative
humidity level is near to or more than 70%-75%, it is advisable to switch on the system in ventilation
mode only.
The cooling efficiency of a system depends on: the cooling unit efficiency, air ducts design, installation
quality, building conditions. Insulated ceilings significantly reduce the internal temperature in
comparison with uninsulated ceilings. The same latter concept is applicable to the air duct.
During normal operating conditions in COOLING mode, the evaporation process leaves mineral
salts accumulation and solid residue in the discharge water, this water is NOT POTABLE.

6.1 First start-up

2.1.1 All models

For optimally using and functioning of the plant/machine it is necessary that, during the first start-up
(in cooling mode), the fan runs at minimum speed and keeps it for at least one complete day.
If this procedure is not observed, during the first day of functioning only, malfunctioning of the
evaporative pads may occur resulting in water drops coming out of the ducts.
During the first start-up of your cooling system, an unusual odour may be detected.
When the evaporative panels start to get wet, they may emit a particular odour, which may be
present for several hours. This odour is a characteristic of the treated cellulose material but it is not
harmful.
Even the fan motor may present a "characteristic" odour for a short period, which is caused by initial
heating and by any paint on the surface of the motor itself.
2.1.2 TC model series
During first start-up, be sure of the right rotation of the fan (indicated with an arrow (adhesive plate)
placed on fan body):
1. Take the machine top off by unscrewing the 4 corners screws.
2. Turn the machine on in ventilation mode
3. Rotation must have the same direction of the arrows as shown:
