Do not know how to work/maintain swamp cooler

I just bought a home with 2 swamp coolers. I am more concerned with my window unit at the moment. It looks like a Bonaire Durango however it doesn't say either anywhere on it. I have never had a swamp cooler before so I have no idea how to use it or maintain it. I have looked every where for an owners manual online and I can't seem to find that either. SOMEONE PLLLLEEEAASSSSSE HELP!!! Thank you.

Make sure you have water to the unit, the water pump is on and the fan is working. No water=no cooling.

    Here is their web site. http://www.bonaire.com.au/support/docume...



    All coolers need a water source, fully wet cooler pads and air blowing over the web pads. Cleaning is best done safely by professionals, usually at the beginning of the cooling season.

Evaporative coolers are only for dry climate conditions or deserts. They cannot cool as much as central air or air conditioners which have compressors and refrigerant. The mechanics are simple requiring a water float valve, pump, spider (water distribution), aspen wood pads, blower, belt, motor, and switch. The unit must have a water supply to replenish the system due to evaporation. Your system may have a float valve which you need to adjust to shut off when the water pan is full. Floats can be adjusted by loosening the pivot screw and moving the float up and down to adjust the turn off level or by turning the float to extend or retract the length changing the water shutoff position. You do not want the water to be so high it flows out the over flow tube but the water should cover pump base. Plug in the unit and turn the switch to pump if you have that option on your unit. This will engage the pump to force water from the pan up to the spider to saturate the pads with water. After a few minutes turn the switch from pump to low or high cool. New aspen pads will have an distinct smell which will go away after a few days of usage. If you do not have a pump setting turn the switch to low or high cool which will blow warm air at first then start to cool down. You may also have a fan setting which will blow outside air without any additional cooling if the outside air is humid. Occasional maintenance is to make sure the pump is pumping water and the filter basket is clean and all the spiders are working with water flowing freely. You can use a flexible wire to force it in a spider tube to clean it if it is clogged. You may want to change the water after a month to keep the system cleaner from slime and calcium. At the end of the season disconnect the water supply and drain the water pan blowing out the water line if the winter is below freezing. Replace the pads if they have calcium build up or dry. Flush the water pan out and clean the Add some oil to the pillow blocks which are the bearings at each end for the blower. Check the belt and pulley for excessive wear. Cover the unit with canvas to prevent cold air from coming in during the winter. Next summer season all you have to do is uncover the unit and hook up the water supply.

Need parts, pump for a ED630J adobe swamp cooler in las vegas, nevada


A swamp cooler PUMP is not really model specific. They are basically small submersible pumps. Contact ANY swamp cooler dealer in LV, tell them you have a 4500 CFM unit and need a pump.
The pump part number for this size cooler is: PN 110436 (there are several alternates)

Contact these folks and tell them what you need:
National Cooler ' Swamp Cooler
3046 Vegas Dr.Suite 1
Las Vegas, NV 89106
(702) 638-8800

If they can not help you... just look under cooling and air-conditioning in the yellow pages and find a dealer near you. This pump is common to nearly every brand in LV. You can most likely buy one at the local home depot, menards, or lowes.
There is also a Little Giant CK-5 "UTILITY"pump that is used for swamp coolers.

Thanks for choosing FixYa,

We have an older swamp cooler and need to have some windows in our home open to get best cooling. Does a mastercool need to have some windows open in our home to give max cooling?


The solution is to install "up ducts" These devices are easy to install and are fairly cheap. With a swamp cooler the best way to use them is to allow them to draft outside with the "up duct" you get the drafting to the outside but also get to remove attic heat too.

Swamp cooler starts up automatically after power outage


generally ther thermostat is the "brain" of the system, check the wiring diagram (if there is one) or the wiring and see if the on off swtch is inseries or parallell to the thermostat, (should usually be in series if it is I would say that the on off switch is the culprit. you cna verify with an ohmmeter to see if it is staying in the closed position.

We bought a Bonaire cooling system at yard sale, it leaks water after it is running for awhile, plus it sprays water out the front


I take it this is a window Unit , the water is coming in the room because the Unit has to be pitched about 1/2 into the back ( outside ) or the drain line is clogged ( dirt) stopping water from flowing to condenser ( that cools the coil)
The water is condensation from warm air hitting the cold coil .

Vulcan-Bonaire : summer breeze


This unit is a cooling unit only. I don't know what switch you are looking at but I don't think it's for the evap. cooler(swamp cooler). I am in the Phoenix, Arizona area and it's very common to have a evap. cooler and a seperate heat/cool system as on the hottest days the evap. cooler doesn't cool enough. I hope this helps. Please give me a positive rating. Thank you.
