Our portable evaporative coolers can be operated in either FAN or COOL mode. In FAN mode, the units do not require water. All SO evaporative air coolers come with low water level sensing to protect the pump when the water reaches the minimum level, however it is strongly recommended NOT to use the units in COOL mode without the proper amount of water in the reservoir. Doing so may damage the pump, shorten the life of the unit and invalidate any warranty. - What voltage does an SO Ltd evaporative air cooler operate with?

refilling with fresh water at least once a week will greatly reduce mineral deposits in the pads and the reservoir and
help to extend not only the life of pads, but also the effectiveness of the units. Do not leave stale water in the
reservoir for an extended period of time. For maintenance information, please refer to your owner’s manual or
