•  Comply with all local legislation and current regulations when using the cooler.
•  Keep the cooler dry, in order to avoid electric shocks. Hands must always be dry.
•  Use only in ventilated and dry areas.
•  For indoor use only.
•  Only power the cooler with the voltage and frequency as specified on the nameplate.
• Do not cover the cooler with paper, cardboard, plastic, metal sheets or any other inflammable material during use, in order to prevent any risk.
•  The cooler must be used on a stable and levelled surface, in order to prevent any risk.
•  Disconnect the cooler from the mains power supply when not in use.
•  Never block the cooler’s air vents or the air outlet.
•  The minimum safety distance recommended between the cooler and walls or other items is 0,5 m.
•  Never move, handle, refuel or conduct maintenance on the cooler when it is connected to the mains or in operation.
•  The cooler (power cable included) must be kept at a suitable safety distance from heat sources.
•  In any case, the cooler must be opened and/or repaired by an authorised after-sales centre.
•  If the power supply cable is damaged, it must be replaced by a technical support centre to prevent any risk.
•  In the event of incorrect cooler operation, immediately disconnect the electrical power supply and contact the support centre.
•  Protect the power cable from potential damage caused by the movement of vehicles or pedestrians. Improper connection to electrical voltage or improper installation may result in electric shocks.
•  Conditions of use:
  •  The temperature of the air: 18°C – 45°C; the Temperature of the water: <45°C.
  •  The air must be free of dust and pollutants, otherwise, cleaning must be carried out more frequently.
• The water used to fill the cooler tank must come from an aqueduct. If it is not possible to draw from an aqueduct, the water introduced must be subjected to a sanitation treatment, according to European Directive 98/82/EC.
  • We recommend using water with a hardness of less than 15°f.
  • The cooler tank must be emptied and sanitised periodically depending on the use.
  • The evaporative panel surfaces must be periodically inspected and sanitised depending on the use.
  • For sanitation operations, biocidal products that comply with European regulation no. 582/2012 must be used.

UNPACKING

Remove all packaging material used to pack and deliver the cooler and dispose of it in compliance with current standards. Check for any damage incurred during transport. If the cooler appears damaged,  immediately inform the dealer from whom it was purchased.
DESCRIPTION
Evaporative coolers cool the air by using the natural process of evaporation of water. The 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 cellulose and is constantly wet by a special system that pumps water.

OPERATION

WARNING: Carefully read the “SAFETY INFORMATION” before switching on the cooler. WARNING: Only use clean water to prevent failures or other anomalies. WARNING: Verify if your electronic 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. The cooler is equipped with a series of fittings and cocks (Fig. 3):

•  WATER FLOW ADJUSTMENT COCK Used to adjust the water supply to the cooler. A maximum water flow rate is obtained with the cock completely open (anticlockwise rotation 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 the 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.

• SWITCH-ON

•  Connect the cooler to the water mains using the threaded fitting

•  Refilling the water tank. When the 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 the water mains supply). In case of manual refilling from the cock, pay attention to the tank’s capacity in order to avoid overflows.

•  Check that there were no leaks during refuelling.

•  Connect the supply plug to the power mains

•  Press ON/OFF / POWER to turn on the cooler

FUNCTIONS OF THE CONTROL PANEL AND REMOTE CONTROL

• 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 activating or deactivating the delayed switch-on or switch-off mode. en -DELAYED SWITCH-ON: When the cooler is on, press the “TIMER” button repeatedly until the desired time is displayed (the number flashes), then SWITCH OFF THE COOLER.
  DELAYED SWITCH-OFF: When the cooler is on, press the “TIMER” button repeatedly until the desired time is displayed, and then the switch-off time is set. NOTE: When the cooler emits an acoustic beep, it means that the tank is empty and the device is operating in fan mode. To restore correct operation in “COOL” mode, refill the water tank. To deactivate the acoustic beep, deactivate the “COOL” function.

• SWITCH-OFF:

•  Press ON/OFF / POWER to turn off the cooler.

•  Drain the tank through the specific drain plug.

CLEANING AND MAINTENANCE

WARNING: BEFORE PERFORMING ANY MAINTENANCE 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 FOLLOWING COMPONENTS MAY BE REQUIRED:

• TANK:
  IT IS RECOMMENDED TO READ THE SAFETY WARNINGS CAREFULLY AND TO CHANGE THE WATER FREQUENTLY.

• Turn off the cooler and disconnect the plug from the power mains.

• Drain the tank through the specific drain plug.

• EVAPORATIVE PANELS AND
  WATER CIRCUIT:

• It is recommended to visually check the condition and the correct position of the evaporative panels on a regular basis (Fig.
  The panels must not be worn, damaged or encrusted and must be positioned correctly in order to avoid gaps between each other. IMPORTANT: Do not attempt to remove the evaporative panels. All operations must be carried out by the after-sales assistance service. IMPORTANT: Handle the evaporative panels with care; do not drill or insert pointed objects in the air inlet grille.

• To ensure proper operation of the cooler, turn off the COOL mode a few minutes before completely switching off the cooler, in order to avoid stagnant water.

• We recommend periodically performing a complete cycle using clean water and appropriate disinfection products and running the cooler outdoors.
  IMPORTANT:

  • The cooler tank must be emptied and sanitised periodically depending on the use.
  • The evaporative panel surfaces must be periodically inspected and sanitised depending on the use.
  • For sanitation operations, biocidal products that comply with European regulation no. 582/2012 must be used.

REMOTE HUMIDISTAT CONNECTION

A remote humidistat can be connected in series to the power supply plug, to manage the automatic switch-on or switch-off of the cooler. After the humidistat has been activated, during normal operation, the cooker switches off. The re-ignition is automatic and the operating configuration is restored keeping the settings prior to switch-off. CAUTION: THE ONLY SETTING THAT IS NOT RESTORED IS THE “TIMER” FUNCTION, IN THIS CASE IN FACE THE COOLER WILL GO IN STAND-BY CONDITION.
