•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

sure no water enters the control panel.
•Any service other than regular cleaning or filter replacement should be performed by an
authorised service personnel. Failure to comply may void the warranty of the unit.
•Do not use the evaporative cooler for any purpose other than its intended use.
•Never use the plug as a switch to turn on or off the unit. Use the provided ON/OFF

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.
APPLICATIONS
•Alternative and economical spot cooling solution for areas and spaces which cannot be sealed or
traditionally air conditioned.
•Dial®Portable Evaporative Cooler can be used in garage, workshop, barn / stable, on patio and
commercial open spaces such as sidewalk cafes and outdoor seating & dining.
FEATURES
•Powerful air-flow perfect for spot cooling.
•Directional swing allows wider area coverage.
•3 fan speeds and oscillation setting for wider and improve air flow: low, medium and high-speed
allow adjustment between maximum cooling and quiet operation.
•Removable and washable dust screen for improved cooling and clean airflow.
•Handle and castors for great mobility.

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.
