►►2. UNPACKING
►2.1. Remove all packaging material used to
pack and deliver the cooler and dispose of it
in compliance with current standards.
►2.2. Check for any damage incurred during
transport. If the cooler appears damaged,
immediately inform the dealer from whom it
was purchased.
►►3. DESCRIPTION
(Fig. 2)
Evaporative coolers cool the air by using the
natural process of evaporation of water. Op-
eration of these air coolers is based on evapo-
rative cooling that uses the energy exchange
between the water and air.
The coolers consist of an evaporative panel, a
fan and a cascade water distribution system.
The fan draws air from outside and passes it
through the evaporative panel, which is made
entirely of cellulose and is constantly wet by a
special system that pumps water.
►►4. OPERATION
WARNING: Carefully read the "SAFETY
INFORMATION" before switching on the
cooler.
WARNING: Only use clean water to pre-
vent failures or other anomalies.
WARNING: Verify if your electronic sys-
tem is earthed correctly. Connection to
the mains must be made in compliance
with the National Standards in force.
Only power the cooler with the voltage
and frequency as specified on the name-
plate.
The cooler is equipped with a series of fittings
and cocks (Fig. 3):
► WATER FLOW ADJUSTMENT COCK (A
Fig. 3):
Used to adjust the water supply to the cooler.
A maximum water flow rate is obtained with
the cock completely open (anticlockwise rota-
tion of the knob).
►WATER SUPPLY FITTING (B Fig. 3):
This is used for the continuous and automatic
supply of water to the cooler (1/2" fitting and
maximum inlet water pressure of 3 bar). After
filling, it can also be moved, always with the
utmost care.
►MANUAL WATER SUPPLY COCK (C Fig.
3):
A water filling cock is provided, which enables
manually filling of the tank.
NOTE: Take note of the maximum capacity of
the tank in order to avoid overflows.
►DRAIN COCK (D Fig. 3):
The base of the cooler is equipped with a
drain cock, which is used to drain water from
the tank.
►►4.1. SWITCH-ON:
►4.1.1. Connect the cooler to the water mains
using the threaded fitting (Fig. 4).
►4.1.2. Refilling the water tank. When water
in the tank reaches the maximum level, a
float will automatically block the flow (it is
possible to operate the cooler while being
continuously connected and fed from water
mains supply).
In case of manual refilling from the cock,
pay attention to the tank's capacity in order
to avoid overflows.
►4.1.3. Check that there were no leaks dur-
ing refuelling.
►4.1.4. Connect the supply plug to the power
mains (Fig. 5).
►4.1.5. Press ON/OFF / POWER to turn on
the cooler (Fig. 7).
►►4.2. FUNCTIONS OF THE CON-
TROL PANEL AND REMOTE CON-
TROL (Fig. 6):
►ON/OFF / POWER: Is used to turn the cool-
er on or off.
►SPEED: Increases or decreases the venti-
lation speed of the cooler. You can choose
from three speeds.
►COOL: Enables or disables the cooling
mode.
►TIMER: Enables to activate or deactivate
the delayed switch-on or switch-off mode.
