Where do I find the part number to my PolarCool?
On the “Stainless and Powder Coated models” raise the hinged lid assembly. Look behind pads (right side) over the spray bar metal cover for an information label. For plastic unit, look on the right hand side, on the splash guard, on the back of the unit.
Why doesn’t my pump work?
Is the pump turned “ON”? Does the reservoir have enough water to raise and trip the low water level switch, if applicable, to allow pump to turn “ON”. Is the pump/hose positioned flat allowing it to prime itself. You may need seat it firmly against the bottom to assist with priming. Do you have correct voltage to the pump? Have qualified electrician check voltage supply from inside the PolarCool control box, at the back of touch pad faceplate or the “toggle” switch, as applicable, depending on the unit you have. If voltage is present, then replace faulty pump. If not, ensure connection points and wiring are good. Replace control box lid assembly, touch pad control plate, or switch as necessary, in order, to get proper voltage to the pump.
What does that sequence of blinking lights tell me?
They tell you it could be low of water or that it is filling the reservoir

What size do I need for my building?
Several things need to be considered for determining the size PolarCool you should need. Remember, our units are tested in environments that include @10 foot ceiling, @ 90 degrees, and good open ventilation to prevent saturation during evaporative cooling process. The following should be taken into consideration: Space limitations, square footage of the area to be cooled, and ventilation in that area. After determining these factors you can reference “Support” navigation button on the website, then access the drop down area and select the different sizes to look at the specifications charts, for each, to determine the unit best suited unit for your application.
Whats the difference in a PolarCool fan and a regular fan or an air conditioner?
Portable Evaporative Cooling Units provide spot and area cooling where you need it, when you need it. Evaporative cooling is a time-tested and efficient means of reducing air temperature by drawing incoming air across a wetted surface. Evaporative cooling is especially useful in situations where air inside the space to be cooled is well ventilated. Evaporative cooling needs only two factors to work: water and moving air. When air is moved across a wet surface, some of the water on the surface evaporates. This action draws heat from the moving air, thereby cooling and dropping the ambient temperature.
How do I replace my selonoid?
Ensure unit is unplugged. Remove the pads, then locate the solenoid inside, it is connected with brass fittings and is wired to a junction box inside fan housing, remove cover of junction box and mark wires and then take the wires loose. Using a wrench, thread the solenoid off of the brass fitting. Thread the new solenoid on making sure that there is pipe tape on the threads. Once this is complete wire new solenoid into junction box, as previously marked. Put cover back on junction box and put pads back in properly. You are now ready for start up
How do I replace my motor?
First you need to unplug unit, then figure out if you have a Zone, 36 inch stainless or a 20 inch zone with a Vosterman motor, (to start you need to remove the pads) all Vosterman motors are changed by loosening the small nuts that hold the arms to the motor, this will allow you to slide the motor away from the arms, once you get the motor slid off of the arms, then take the touch pad loose so that you can get to the wiring of the motor,(pay close attention to the wiring to ensure you wire back the way it came off), unwire the cord from the connector on the touch pad to leave the cord with the motor, your new Vosterman motor comes prewired with it’s on cord, once the motor is out of unit then pop the black cap off of prop to access the nut that holds the prop onto shaft, (be careful not to lose the key that is in the slot), once you remove the prop from the old motor go ahead and place it on your new motor ensuring that the key is in the correct place and tighten nut and pop the black cap back on, the you are ready to slide the motor back onto the arms where you loosened the small nuts, once the motor is in the correct place tighten the nuts, then you are ready to wire motor into touch pad and place small screws and tighten them, then put your pads back in correctly and you are now ready to run your unit. If you have a 48 inch unit, be sure unit is unplugged, take your belt loose from small pulley that is on motor, then remove the 4 bolts that hold the motor to the stainless steel cross brace, take the small plate off of back of motor to access the wiring of the motor, (pay close attention to how the wires are hooked up to ensure that you wire back the same way that you take them off), once you have motor off then take the small pulley off of motor being careful not to lose the small key that is inside the pulley, then you take the small pulley and mount it on your new motor making sure you get the small key in the correct slot and the pulley in the correct place on motor shaft, (most of the time the pulley is flush with the end of the motor shaft, but you may have to move in or out), once this is complete mount the motor back to the stainless steel cross brace using the bolts and nuts that you took off and tighten them, then remove the small plate from motor and wire the cord back into new motor the same way you took them out, then put your pads back in correctly, once this is complete you are ready to run tour unit, watching it making sure you have everything in line. If you have a 18 inch or a 24 inch unit they are very similar, first unplug unit, take your pads out to access motor, remove the small plate form back of motor to access wiring (paying close attention to how it is wired to ensure you put wires back like they were), reach through and remove the prop from the shaft of the motor, then remove the 4 small nuts from the face of the motor that holds it to the stainless steel, once the old motor is out place the new motor in putting the small nuts back on the threaded studs that are on new motor and tighten them properly, then take something and rake the excess threads off of studs to ensure that they don’t hit the prop., then you wire the cord back into new motor just like it came out of old one, then replace the prop back on the shaft of the motor and make sure it is on correctly and tight, put your pads back in and your ready to run unit.
Why does my blade turn slow?

How do I adjust my float valve?
Unplug unit, then hook water hose to the unit, then remove the pads to get access to the float valve, once your at the float valve loosen the small bolt that holds the float arm on and turn the water on and pull the arm of the float out and tighten the small bolt until you get the correct amount of water in bottom pan, once this is complete put pads back in correctly and you are ready to run unit
How do I adjust my water flow?
All units come with a shut off valve either inside unit or outside unit, if it is on the inside you must remove at least one pad to access the valve, (you may get some water on you or on floor)with pump running adjust the valve either towards close or open which ever you needs are for correct water flow, if your valve is on the outside all you have to do is turn towards open or close, (if your pads are to dry then open it some more, if your pads are to wet then close it some) once you have pads in or have it adjusted then you are ready to run your unit
How do I replace my liquid level sensors?
First unplug unit, remove pads, then remove pads from back to get access to the sensor, on stainless units loosen the plastic nut that holds the sensor onto the stainless bracket, take the touch pad loose from the side of the unit to gat access to the wiring (pay close attention to the wiring to ensure you wire back just like it was) remove the wires from the connector and pull wires from box, run your new wires through the same hole and wire back to connector, then attach the sensor back to the stainless bracket with the plastic nut and tighten properly, if you have a plastic unit it will have two sensors that are run into a PVC pipe and are wired into a junction box (one is for low water and the other is for high water) remove the cover of the junction box and locate the white wires ) make sure you mark the wires to each sensor to ensure you get them back in the correct place, once you have threaded the old sensor out you will need to thread the new wires through the PVC and thread the sensor into the fitting (make sure there is pipe tape on threads of sensor), run back into junction box and wire back just like it was and put pads back in and your ready to run unit

How does the evaporative cooling process work? Temp. Differential?
Portable Evaporative Cooling Units provide spot and area cooling where you need it, when you need it. Evaporative cooling is a time-tested and efficient means of reducing air temperature by drawing incoming air across a wetted surface. Evaporative cooling is especially useful in situations where air inside the space to be cooled is well ventilated. Evaporative cooling needs only two factors to work: water and moving air. When air is moved across a wet surface, some of the water on the surface evaporates. This action draws heat from the moving air, thereby cooling and dropping the ambient temperature. This drop is dependent on the temperature and relative humidity the unit is placed in.
How do I know which size fan I have?
On the "stainless or powder coated models" raise the hinged lid assembly. Look behind pads (right side) over the spray bar metal cover for an information label. For plastic unit, look on the right hand side, on the splash guard, on the back of the unit. On the grey sticker you will see your units part number and a Description that will say PC 18 or PC 24 or PC 36 or PC 48
