COOLER LOCATION
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 filling or emptying the water tank.
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.
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 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, the water inlet valve will automatically
stop the water supply from overflowing.
Please open the water valve for minimum flow as too much pressure
could damage the inlet pressure control system.
WARNING: The maximum water inlet pressure is 0.5 MPa.

CLEANING & DRAINING THE WATER TANK
WARNING:
Before cleaning the unit, switch the unit OFF and disconnect from the electrical socket.
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: Always ensure the water in the water tank is above the minimum (Min.) water level mark for
both Continuous & Manual Water Refill. Running the unit in Cool mode with inadequate water may
cause pump failure.
WARNING: Do not fill water tank with dirty water or salt water. This can damage the unit and
Honeycomb media.
Note: The water capacity refers to the total volume of water that can be contained within the air cooler
water tank and water distribution system. The water capacity in the tank at the “Max.” indicator level
may be lower than the actual water capacity of the air cooler.
Using a portable container or a garden hose, you can refill the water tank manually by pouring water
into the water tank through the water inlet hole located at the top of the air cooler.
Check the water level indicator to know when the water tank is full. Do not fill water above the "Max."
water level mark to avoid water droplets collecting on the louvers.

Manual Water Tank Refill:
FILLING WITH WATER (CONTINUED)
The appliance is supplied with three Honeycomb Cooling Media pads.
The Honeycomb Cooling Media are located inside the Rear and Side Grills. Follow Steps 1 to 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.

CLEANING THE HONEYCOMB COOLING MEDIA

USE & OPERATION (CONTINUED)
Remove the screws from the Rear Grill of the Air Cooler.
Carefully pull out the Rear Grill from the Air Cooler.
The Honeycomb Cooling Pad is secured on the Rear Grill by two Horizontal Bars that are fixed in
place by two screws on the Left and Right Sides of these Horizontal Bars. Remove these screws to
release the Horizontal Bars.
Pull out the Honeycomb Cooling Pad by sliding it out from the Rear Grill. Replace with the new
Honeycomb Cooling Pad by sliding into the grooves of the Rear Grill until it fits comfortably and
securely in place on the grill. Replace the Horizontal Bars back onto the Rear Grill by replacing the Left
and Right Side screws and tightening them in place. This secures the Honeycomb Cooling Pad in
place on the Rear Grill.
Repeat steps 1 to 4 to remove the Honeycomb Cooling Pad on the Left and Right Side Grills.
WARNING: DO NOT operate the Air Cooler when any or all of the Rear or Side Grills are removed
from the Air Cooler, or if there is a loose-fitting Rear or Side Grill. Doing so can cause serious injury or
dangerous electrical shock.

Removing the Honeycomb Cooling Media:
CLEANING THE HONEYCOMB COOLING MEDIA (CONTINUED)
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.
