Operation

Manual Control Units

•Pump setting. The rotary switch has 6 settings. The “Pump” setting will operate the pump without the blower. For best results turn the switch to “Pump” for a few minutes to wet the pads before operating the fan.

•High and low cool settings. The “High Cool” and “Low Cool” set- tings operate both the pump and the blower. Turn the unit to “Low Cool” when possible. This lower speed allows the air to stay longer in the wet pads and therefore increases it’s cooling efficiency.

•High and low vent settings. The “High Vent” and “Low Vent” settings operate the blower without the pump. This is useful on cool nights or at times when just a fan is desired.

Remote Control Units

These units may be controlled using the 3 buttons on the front panel of the cooler or with the remote control.

• PUMP button. Pressing this button toggles the pump on and off.

When the LED is lit, the pump is running. For best results turn

on the pump for a few minutes to wet the pads before operating

Exhaust Air

If the unit is used in an enclosed area, open windows or doors to ensure adequate exhaust. Without an outlet to exhaust the air, humidity will build up in the enclosed space and the unit will not cool adequately.

Cooler Installation

the fan. The pump must be on while operating the fan for cooling.

You may also want the pump turned off at times when just a fan is

desired.

• FAN button. Pressing this button will cycle the fan through High

Speed / Low Speed / Off. The LED’s on the front of the control

indicate wether the fan is on high speed, low speed or off (no LED’s

lit). Note: There will be a 2 second delay between a button press

and the operation of the fan.

• ON/OFF button. Pressing this button while the pump or fan is on

will turn everything off. Pressing it again while in the off state will

return the fan and pump to their previous operating settings. When

first plugging in the cooler or after power has been interrupted,

pressing the On/Off button will start the cooler in the default state

which is with the pump on and the fan on high.

• Remote Control. To operate the cooler with the remote you must

be within 20 feet and in sight of the cooler. Aim the remote at the

front panel. The buttons on the remote control have the same func-

tions as the buttons on the front panel of the cooler. The remote

uses two AAA alkaline batteries which are included. A holder for

mounting on a wall is also included with the unit.

•Install float valve. Refer to figure 3. Install the valve in the pro- vided hole in the corner post ((R)M301A, (R)M401A) or louvered side (M201A) using the provided washer and nut. Install the included garden hose adapter to the float as shown if attaching a garden hose to the unit. A 1/4 inch water line may also be used to supply a continuous amount of water to the unit.

•Fill pan with water. You may fill the pan manually for up to 3 hours of cooling. For automatic filling you may attach a garden hose to the garden hose adapter or a 1/4 inch water line to the float valve.
