• Do not move or tilt the unit while the water tank is full.
• The outdoor use of this portable evaporative cooler must be supervised.
• The unit is not designed to be exposed to wet conditions such as rain.
• This unit can only be connected to a 110-115V, 60Hz and Single-Phase electrical outlet.
• This evaporative cooler has been tested and is safe to use. However, as with the use of any electrical appliance, take care when using the unit.
• Test and reset the GFCI plug before connecting it to an electrical outlet.
• Do not connect the unit to an extension cord for power supply.
• Never operate this appliance if the cord or plug is damaged.
• A damaged power cord should be replaced by the manufacturer or a qualified electrician.
• This evaporative cooler is not to be operated by persons (including children) without experience and knowledge of using the cooler.
• Do not leave children near the evaporative cooler unsupervised.
• Do not touch any moving or rotating parts inside the unit.
• Never insert fingers or any other objects though the louvre or guard.
• The operation of the evaporative cooler should not be left unattended for an extended period.
• Disconnect the evaporative cooler from the electrical outlet before cleaning, maintaining or servicing the unit.
• Do not clean the unit by spraying it or immersing it in water. Use a moist cloth to wipe and clean the exterior of the unit. Use caution when wiping the Control Panel; make sure no water enters the control panel.

ENERGY SAVING AND UNIT SAFETY PROTECTION TIPS

• Operate the unit at a location that has cross ventilation. Evaporative air coolers use evaporation to achieve a natural cooling effect which requires cross ventilation for maximum efficiency.
• To ensure the evaporative cooler operates efficiently, do not block or restrict the air-intake through the inlet grills on the side and back, or airflow out of the louvre in front.
• For maximum performance, do not place the back of the unit within 20 inches of a wall or other objects.
• When the unit is in operation, the water in the water tank must not exceed the MAX level and must not fall below MIN level.
• Keep the Dust Screen clean to allow better air-intake and efficient operation of the unit.
• This unit will lose efficiency if the relative humidity in the room exceeds 60%.
• The ambient operating temperature range is from 41°F to 125°F.
• This evaporative cooler may operate as a humidifier in low temperature environment using warm water (not hot water) instead of cool water.

HOW EVAPORATIVE AIR COOLERS WORK

The evaporative cooler cools the air by means of evaporation. When water evaporates, liquid water is converted into vapor using the thermal energy in the air resulting in a lower air temperature and spot cooling effect. Evaporative cooling therefore causes a drop in the temperature of air proportional to the sensible heat drop and an increase in humidity proportional to the latent heat gain.

• The recommended relative humidity for optimum operation is 60% or lower. A drier climate makes for more noticeable cooling.
• The evaporative air cooler should not be used in enclosed or sealed spaces. It must be kept level and there must always be water in the water tank. In a room setting, doors and windows should be open to allow cross air flow.
• When the product is used for the first time the Honeycomb cooling media may have an odor. This should dissipate within a week of use.

EXTERIOR PARTS OF THE EVAPORATIVE COOLER

UNPACKING AND INSTALLING CASTERS

• Keep the evaporative cooler in an upright position and remove the packaging.
• Make sure all the parts are present: Castors (4pcs) & Screws (16pcs).
• Lay the evaporative cooler on its side gently. Locate screw holes for the casters under the Reservoir. Use the screws provided to fasten the casters to the underside of the Reservoir. Set the cooler right-side up when the casters are installed.

CONTROL PANEL OPERATIONS

| Use this dial to select fan speed. To turn “on” the fan, turn “FAN” dial from “OFF” to “L”, “M” or “H” (Low, Medium or High).
---|---
****| To activate evaporative cooling turn “PUMP” dial from “OFF” to “ON”. Ensure that the water level is sufficient for the operation. If this function is not turned on the unit operates as a fan / air cleaner.
| **** To activate the swing mode turn “SWING” dial from “OFF” to “ON”. The airflow will swing from left to right. The up-down airflow can be controlled manually by adjusting the horizontal louvre.

OPERATING THE EVAPORATIVE COOLER

FILL THE RESERVOIR
Fill the reservoir with clean water through the Water Filler Door manually. To open the Water Filler Door, depress the door at the center on the top edge of the door. Do not fill the water beyond the maximum water level. Close Water Filler Door when the reservoir is filled. Alternatively, connect a garden hose to the hose valve (use the hose adaptor provided) which also provide continuous water fill. The reservoir must be filled with a minimum volume of water before using the cooling function. The water has to be at least half full on the Water Level Gauge. PLUG IN THE GFCI PLUG INTO AN GFCI ELECTRICAL OUTLET IF AVAILABLE
Note: The GFCI Plug can be plugged into an ordinary 110-115V electrical outlet.
Press the “Re-set” button on the GFCI plug first and connect the GFCI power plug to a GFCI electrical outlet. Re-set GFCI outlet if necessary. TO TURN ON THE EVAPORATIVE COOLER, TURN THE “FAN” ROTARY DIAL FROM “OFF” TO “L, M OR H”. USE THIS DIAL TO SELECT FAN SPEED. TO ACTIVATE EVAPORATIVE COOLING, TURN “PUMP” DIAL FROM “OFF” TO “ON”. Check the water level to ensure that the water level is sufficient for the operation. TURN THE “SWING” DIAL FROM “OFF TO “ON” THE “OSC” BUTTON FOR THE AIRFLOW TO OSCILLATE LEFT AND RIGHT.
Note: It is completely normal if the cooler has a slight odor or the water tank has slight discolouration when it is used for the first time.

MAINTENANCE

CLEANING
CAUTION: Turn off the evaporative cooler and disconnect the plug from the electrical outlet before cleaning, servicing or performing any maintenance on the unit.
CLEANING THE EXTERIOR SURFACE OF THE EVAPORATIVE COOLER

• Clean the plastic housing with a duster or a soft moist cloth.
• Do not use chemical solvents (such as benzene, alcohol or gasoline) as they may cause irreversible damage.
• Use care when cleaning around the control panel and the control panel itself; make sure no water enters the control panel. Control Panel warranty does not cover damage caused by water.

CLEANING THE RESERVOIR

• Unplug the appliance then remove the screws securing the rear filter frame.
• Lift the filter frames to remove from the unit.
• Drain the Reservoir by removing the Drain Plug on the underside of the Reservoir.
• With a cloth (dipped in mild detergent solution), wipe the Reservoir and rinse it with water.
• Cleaning the Reservoir at least once a week will help reduce any mineral deposits and keep the filters clean.
• Do not run the unit in cooling mode with stale water in the Reservoir.
• Empty the reservoir and refill it with fresh water if water has been left in the Reservoir for an extended period.

MAINTAINING AND CHANGING THE RIGID MEDIA PADS
The frequency of cleaning the Rigid Media Pads depends on local air and water conditions. In areas where the mineral content of the water is high (hard water), mineral deposits may build up on the media pads and restrict air flow. If mineral deposits remain on the media pads, they should be removed and washed under fresh water or replaced. We recommend cleaning the media pads at least every two months, depending on water conditions. For best results, allow the media pads to dry after each use by turning off the cooling function for 15 minutes (without water in the Reservoir) before turning the unit off. Go to www.dialmfg.com/pec/technical-data. for detailed instructions on removing and replacing Rigid Media Pads.
END OF SEASON MAINTENANCE

1. Empty the reservoir and wipe it with warm soapy water.
2. Dry the reservoir and clean the Honeycomb pads.
3. Cover the unit and keep it in a dry place.

TROUBLESHOOTING
