2.5 Emergency situations
It is absolutely forbidden to use water to put out fires.
Use exclusively powder or CO2 extinguishers
In case of emergency immediately turn the machine off and cut off the electrical circuit
through the omnipolar isolator switch, identify and solve the problem, contact a
licensed
technical service center
.
SECTION 3 – MAINTENANCE
3.1 End of season maintenance
•
Cut power inlet off by using the main isolator
-
switch.
•
Close the water supply.
Empty the water supply plant to avoid bursts due to icing.
•
Take the machine top off.
•
Check that waterways are clean and that there are no obstructions in the water supply and dis
tributor in the upper part of the unit. Clean any debris in the water pump.
•
Fully clean the tank of the unit. Use a mild detergent, not a solvent cause it may
reacts with
plastic materials.
•
Replace and fix well the machine top using the bolts supplied.
We recommend annual service to the system to maintain it in perfect operation conditions
.
Before
the machine start
-
up the equipment should be checked to make sure it will work properly, so any
maintenance or repairs necessary could be carried out before the working season
of the unit.
The functioning of the evaporative cooler is based on an important principle: It introduces big quanti-
ties of fresh air into the building and removes hot exhausted air through doors, windows and other
openings. If the system is not able to expel the air volume introduced into the building, the efficiency
would be compromised. INLET FRESH AIR = OUTLET HOT AIR. A very simple principle.
If the sys-
tem is able to expel all the air introduced into the building, the system operates at the highest efficien-
cy. The ideal condition is when, into the building, to position the air diffusers are positioned away
( better on the opposite side) from the openings (windows, doors, etc.) so the air passes through the
building while is cooling it. Maximum efficiency can be reached by adjusting the dimensions of the
window and door openings. Never close the openings: if they are closed, no changes of air will occur,
consequently reducing the cooling effect and increasing the relative humidity level inside the building.
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). More dry is
the external air, more cooling capacity could be reached by the system. Your evaporative cooling sys-
tem will not operate at maximum efficiency during high humidity days however it will still reach an effi-
cient cooling level. In areas with high relative humidity, the evaporative air cooling system must be
oversized to guarantee more air changes, or in other words, it must have higher capacity to compen-
sate 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 inter-
nal temperature in comparison with uninsulated ceilings. The same latter concept is applicable to the
air duct.
