Cleaning And Maintenance - Master BC 121 Manual De Instrucciones Para El Uso Y Mantenimiento

►►3. DESCRIPTION
(PIC. 2)
The evaporation coolers cool the air by using the
natural process of water evaporation. Operation of
these air coolers is based on evaporative 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 cellu-
lose and is constantly wet by a special system that
pumps water.
►►4. OPERATION
WARNING: Carefully read the "SAFETY INFOR-
MATION" before switching on the cooler.
WARNING: Only use clean water to prevent fail-
ures or other anomalies.
WARNING: Verify if your wiring system 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 nameplate.
Depending on the model, a number of fittings and
valves are found on the cooler (PIC. 3):
►WATER PARTIALISATION VALVE (applicable
depending on the model) (A PIC. 3):
Used to adjust the water supply to the cooler panel.
A maximum water flow rate is obtained with the cock
completely open (anticlockwise rotation of the knob).
►WATER SUPPLY FITTING (B PIC. 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 PIC. 3):
A water cock/hatch is present, which allows the tank
to be filled manually.
NOTE: Take note of the maximum capacity of the
tank in order to avoid overflows.
►DRAIN COCK (D PIC. 3):
The base of the cooler has 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 us-
ing the threaded fitting (PIC. 4) and refill the water
tank. When water in the tank reaches the maxi-
mum 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/hatch,
pay attention to the tank's capacity in order to
avoid overflows.
►4.1.2. Check that there were no leaks during re-
fuelling.
►4.1.3. Connect the supply plug to the power mains.
►4.1.4. Press ON/OFF / POWER to turn on the
cooler (PIC. 5).
NOTE: When the cooler emits an acoustic beep,
it means that the tank is empty and the device is
operating in fan mode. To deactivate the acoustic
beep, press the "COOL" button.
►►4.2. FUNCTIONS OF THE CONTROL
PANEL AND REMOTE CONTROL (PIC. 6):
►ON/OFF / POWER: Is used to turn the cooler on
or off.
►SPEED: Increases or decreases the ventilation
speed of the cooler. You can choose from three
speeds.
►COOL: Enables or disables the cooling mode.
►TIMER: Enables to activate or deactivate the de-
layed switch-on or switch-off mode.
-DELAYED SWITCH-ON: With the cooler off,
press the "TIMER" button several times until the
intended number of hours is displayed, which
flashes on the display (for example in no. 4, a
countdown begins from 4 hours before automatic
switch-on).
-DELAYED SWITCH-OFF: With the cooler on,
press the "TIMER" button several times until the
intended number of hours is displayed, which
flashes on the display (for example in no. 4, a
countdown begins from 4 hours before automatic
switch-off).
►SWING (applicable depending on the model): En-
ables or disables the automatic swing of the fins
to direct the air flow.
►►4.3. SWITCH-OFF:
►4.3.1. Press ON/OFF / POWER to turn off the
cooler (PIC. 5).
►4.3.2. Drain the tank through the specific drain
cock (PIC. 7).
►►5. CLEANING AND MAINTENANCE
WARNING: BEFORE PERFORMING ANY MAINTE-
NANCE OR REPAIR, DISCONNECT THE POWER
CABLE FROM THE MAINS.
DEPENDING ON THE ENVIRONMENT WHERE
THE COOLER IS USED, DUST, DIRT OR WATER
QUALITY CAN AFFECT THE PERFORMANCE OF
THE UNIT. THEREFORE, CLEANING THE FOL-
LOWING COMPONENTS MAY BE REQUIRED:
