    Honeywell-CO301PC-Portable-Evaporative-Air-Cooler-figure-3

    • Power: ON / OFF
    • Speed: Low / High
    • Cool: Controls cooling or fan option
    • Swing: Controls the motion of the louvers

    NOTE

    • The remote control requires two new AAA dry cell batteries for replacement.
    • Open the battery compartment at the back of the remote control and insert two batteries inside. Care must be taken to insert the batteries according to the correct polarity (+ / –) markings shown inside the battery compartment.
    • Always point the remote control signal transmitter towards the unit when operating. Make sure that the signal path is not obstructed.
    COOLER LOCATION

    Make sure to position the air cooler correctly before you set up and start using the product. Please refer to the COOLER LOCATION section of the separate Safety & Maintenance Guide.

    FILLING WITH WATER

    It is ideal to use the Continuous Water Supply Connection to run the unit for long periods of time without refilling the tank. This also helps prevent pump failure in case the cooler is running with inadequate water in the tank.

    CAUTION: Unplug the unit from the electrical power outlet before emptying or refilling the water tank.

    Continuous Water Supply Connection

    Honeywell-CO301PC-Portable-Evaporative-Air-Cooler-figure-4

    For a continuous water supply, you will need a garden hose that is connected to a mains water supply.

    • Locate the male connector at one end of the garden hose. Insert the garden hose connector into the water inlet valve of the cooler. Screw and tighten the water inlet valve onto the threaded part of the garden hose connector, making sure the hose connector is secured to ensure there will be no leaks. If there is a leakage, the hose and the water inlet valve may not be connected properly. Try to disconnect, replace and tighten the water inlet valve again.
    • When the connection is secured, turn ON the water supply and the water will flow into the water tank of the cooler.
    • The cooler is now set so the water refills automatically when the water tank is empty, or when the water reaches below a minimum level.
    • When the water tank is full of water, the water inlet valve will automatically stop the water supply from overflowing the water tank.
      WARNING: The maximum water inlet pressure is 0.5 MPa.

    Manual Water Tank Refill

    Honeywell-CO301PC-Portable-Evaporative-Air-Cooler-figure-5

    Open the Water Fill Door located on the side of the unit. The Water Level Indicator is located at the side of the unit. Refill the water tank when water level is low. Do not fill water above the “Max.” water level mark to avoid water droplets collecting on the louvers. Check the water level in the tank before running the COOL function. Make sure that the water in the tank is above the minimum water level mark. Running the unit in COOL mode with inadequate water may cause pump failure.

    LOW WATER ALARM

    The unit is equipped with a low water sensor. In Cooling Mode, when water in the tank is below the minimum level, you will hear a beeping sound and the will flash continuously. The unit will automatically pause evaporative cooling. Refill the water tank to deactivate Honeywell CO301PC Portable Evaporative Air Cooler the alarm in cooling mode. First switch OFF the unit and unplug from the power outlet. Fill the water tank with water above the minimum water level mark. Plug in and switch ON again.

    To deactivate the alarm and continue using the unit as a fan (without evaporative cooling), switch the unit OFF and then ON again. The Low Water Alarm will not activate in Fan only mode. The Low Water Alarm will sound again if the COOL function is activated while the water tank is still empty.

    CLEANING & DRAINING THE WATER TANK

    Below are instructions on how to clean and maintain your air cooler. If the cooler will not be used for a long period of time, please refer to the STORAGE & MAINTENANCE GUIDELINES located in the separate Safety & Maintenance Guide.

    WARNING: Before cleaning the unit, switch the unit OFF and disconnect from the power outlet.

    • Move the unit to a location where the water can be drained. Remove the cap from the Drain plug located at the bottom of the unit. Allow the tank to empty.
    • Refill the water tank with clean water, up to the maximum level and drain it completely.
    • Use a damp cloth to remove the dirt and dust from the surface of the unit. Never use corrosive elements or chemicals to clean this product.
    • When the product is not in use, store the unit in a dry place out of direct sunlight.
    CLEANING THE HONEYCOMB COOLING MEDIA
    • The appliance is supplied with two Honeycomb Cooling Media pads.
    • The Honeycomb Cooling Media are located inside the Front & Rear Grills. See Step 1 to Step 5 for instructions on how to remove them from the unit for cleaning and maintenance.
    • Do not run the unit in COOL mode with stale water in the tank. You must empty the water tank and refill with fresh water, especially if the tank has not been cleaned in a long time.
    • The cleaning frequency for the Honeycomb media depends on local air and water conditions. In areas where the mineral content of water is high, mineral deposits may build up on the Honeycomb Cooling Media and restrict air flow. Draining the water tank and refilling with fresh water at least once a week will help reduce mineral deposits. If mineral deposits remain on the Honeycomb Cooling Media, the media should be removed and washed under fresh water. The media should be cleaned every two months or sooner, depending on your needs.
    • For best results allow the Honeycomb Cooling Media to dry after each use by turning off the cool function 15 minutes before turning the unit off.
