El enfriamiento por evaporación funciona a través de la absorción de calor por evaporación de la humedad. En pocas palabras, el calor se elimina del aire como el agua se evapora. Usted siente este principio en acción cuando se sale de una piscina de natación o de la ducha y se siente fresca como el agua se evapora de la superficie de la piel. Su enfriador evaporativo funciona de la misma manera. El ventilador extrae el aire exterior caliente a través de las almohadillas de refrigeración húmeda, donde el aire se enfría por evaporación y luego se descarga desde el enfriador.

Evaporative cooling works on the principle of heat absorption by moisture evaporation. Simply put, heat is removed from the air as water evaporates. You feel this principle in action when you step out of a swimming pool or shower and feel cool as water evaporates from the surface of your skin. Your evaporative cooler works on the same principle. The fan pulls hot outside air through the wet cooling pads, where the air is cooled by evaporation and then discharged from the cooler.

GENERAL HAZARD WARNING

USE ALL PRECAUTIONS AND DISCONNECT FROM POWER SOURCE BEFORE PERFORMING ANY MAINTENANCE.

5. Prior to putting your cooler away for winter, always:
   • Drain the tank and wipe out clean.
   • Clean the filter
   • Reassemble and run on FAN ONLY for 30 minutes to dry out the filter.

Location!
Having completed assembly of your cooler, position the unit with its back to an open window or door. This will allow fresh air to be drawn through the cooler and exhausted from the room. Constant air change is essential and part of the fresh air benefit from evaporative air cooling.
This cooler is equipped with an automatic shut off feature for the pump if the unit runs out of water.

Safety Rules

1. Read and follow all instructions, cautions, and warnings. Failure to do so could result in personal injury, death or property damage.
2. Unit must be in the OFF position and UNPLUGGED from power receptacle before performing any maintenance.
3. Make sure the electrical power source conforms to the requirement of the evaporative cooler(s) as well as local codes. The power requirement for the PC-31 is 115v, 2.8 amps.
4. To reduce the risk of fire or electrical shock, do not expose electrical connections to water.
5. Do not touch electrically live components.
6. Adequate ventilation is required. When used in enclosed spaces, it is recommended to open a door or window to draw fresh air in.
7. Assure that all power cords do not come in contact with any sharp edges, hot surfaces or chemicals. Im-mediately replace any damaged parts.

Starting and using the cooler

Cooler Setup and Operation
PC-31 is pre-assembled and ready to operate. Simply remove the packaging and then carefully remove the unit from the box. Install Casters. Lock the 2 locking wheels before filling and turning on fan to keep the cooler from moving from the air velocity.

NOTICE: the cooling pad will have a slight odor when it is new. This is normal. It will dissipate after a period of time depending on the use time. Draining the tank often during the break-in period will help speed this up. (See draining tank in section 5)

Filling Cooler or Connecting to Water Supply
Move the cooler to an area where it can be filled

Manual fill method
The cooler can be filled via the front fill door by hose or bucket. Using the water fill indicator to monitor water level, simply depress the fill door and the spring lock will release and open it. To close, simply push it closed and locked.

Auto fill connections
Connect to a water supply using a garden hose or coil hose, or a direct water line. Simply attach hose adaptor (supplied with cooler) to the float valve nipple protruding from cooler. Verify water tight connections by visually examining the hose connection

CAUTION : Water inlet pressure should be limited to a maximum 50 PSI. If valve is overcome, install a pressure reducer (25 PSI) on nipple first. (It can be obtained at hardware stores in irrigation section.) Hose bib needs only be opened slightly to supply water to float valve and the cooler only needs to be about half filled when in auto fill configuration. The float is already set to that level.

Connecting to a power supply
Plug the cooler into any 115 volt power supply. It is permissible to use extension cords when needed. If there is no power to the unit, reset the GFCI.

To replace the battery, slide the back panel of the remotecontrol down to release it. Remove old battery and replace with CR 2025 round battery.

Cooler Maintenance

WARNING
DO NOT remove back panel with cooler running.

For best operation and long useful life the following maintenance and cleaning procedures should be followed.

Cleaning Cooler and Pads
At regular intervals your evaporative cooler should be shut down and disconnected from power supply. The water tank should be drained of dirty water and sprayed out with fresh water and refilled. The more you do this the better it will work and less calcium will develop on pads or other surfaces. You may spray through the cooling pads to wash them out and allow water to deposit in the tank to be drained away. The removable panel and media pad can be sprayed out on the ground to clean pad. Use light pressure when spraying pads. NEVER spray pads with water while cooler is operating and fan is running. This can cause damage to motor and will void the warranty.

Removal of the Back Panel
(Disconnect power supply before this procedure.)
Unscrew the screws at top of back panel (3). Lift panel up and pull out at the bottom. Then slide panel out of the cabinet. You will now have access to the pump, float valve and water distributor spreaders.

Draining the Cooler Tank
Unscrew drain cap from drain assemble and drain away water. You may tip the unit carefully to the drain side to help drain all the water out.

Removal and Replacement of Cooling Pad
The cooling pads are made from a special resin-impregnated craft paper specially designed for evaporative cooling. They will last many years if maintained properly and water quality is maintained. It is not necessary to remove the pads to clean them.

Inspect the pads for deposits of calcium on the air-entering side. If the flute cells are clogged or the pad is very heavy it may be time to change the media. New cooling pad can be purchased where you bought the cooler. Follow these steps for replacing the pads.

1. With access panel removed, simply pull off the pad retainer disc from the pad pin. Older models may have a pushed on pin that will need to be pulled away using pliers to grasp disc and pull away. Be careful not to break the pin although the new pads will come with new pins and disc. The newer models will have a threaded disc that will unscrew from the pin
2. With disc removed, remove the pins from the pads and carefully remove pads from the fixed side mounting frame. Then do the same for the back panel or panels.
3. Cooling pads are made with a 45/45 flute and can be installed either side to the frame. Just make sure the distribution pad that is fixed to the top of the new media pad is at the top. This allows water get onto the top of the pad evenly. The installation of the pads is opposite of the removal, install the pad, insert pins and install the retaining disc.
4. Reinstall the back panel and you are ready to use the cooler again.

The submersible pump is mounted inside the tank to the bottom with a retention bracket. While you are cleaning the cooler the pump may be removed and the strainer cap on the bottom of pump can be cleaned of debris. If pump has failed and needs replacing follow these steps:

1. Remove retention bracket.
2. Remove the switch control panel from the top of cooler, by inserting a small screwdriver into the tap slots and pop loose.
3. The pump is connected to the control via the white plastic clip. Disconnect the pump clip and feed the plastic clip through the control box into the cooler.
4. The pump cable is connected to the cooler by twist clips that are mounted in the side of the corner between the left pad and the front of cooler. You may have to remove that pad to get to the clips. Also there may be cable ties holding cable to the motor mounting bracket. Remove the pump from cooler when cable is free.
5. Reinstall the new pump in reverse. Being sure to reconnect the cable in the twist ties and secure the cable in a manner of which it stays clear of fan blade when cooler is running. Reattach the pump clip in the control box and reinstall the control panel in its place. Be sure not to pull any other wires loose from control switches when you have panel loose.
6. Reinstall the control panel into the cabinet making sure it is seated.

Float Valve Replacement or Adjustment:
(Disconnect power supply before this procedure.)
The float valve is mounted to the left side of cooler if you are facing the front grill. It is held in place by the retaining nut that is visible from the outside. The rubber washer is between the nut and cabinet. The rear panel will have to be removed to adjust the float (if the water level is too high or too low) or remove and replace a float that has failed to shut of water supply. Note: Be sure that the PSI of the supply water is within the 50 PSI spec. before determining the float has failed.

1. The float valve can be purchased where you purchased your cooler.
2. Remove any hose adapters attached to the float valve nipple.
3. Remove the rear panel assembly as instructed in Section 5.
4. Remove the float valve retaining nut and rubber washer. Remove float valve from cabinet.
5. Reinstall the float valve in reverse. Set the valve adjustment to around 60 degrees for best results.

Troubleshooting Guide

Check the POWER switch, push it to “ON”.
The TIMER switch is “OFF”, turn it to “ON”.
Make sure cooler is not plugged into a tripped GFIC outlet. If so, reset

GFCI or move to non GFCI outlet.

Cooler does not pump| Pump is not activated. Push the PUMP switch to “ON”.
Water level is low. Fill with water and make sure pump is activated.
Be sure the pump and pump hose is clear of debris.
Pump may be defective. Replace pump.
Fan does not operate| Check that unit is plugged properly.
Check the POWER switch, push it to “ON”.
If connected to a GFCI outlet, check if it is tripped.
Troubleshoot rotary switch.
Replace motor capacitor.
Louver does not operate| Louver does not move. Louver switch. Position to “ON”.
Check Oscillator motor for proper placement and operation.
Water leakage| Check the cap of the drain assembly, make sure it tightened.
Inspect tank for cracks or breakage
Make sure cooler is level.
Check media pads for buildup allowing water out on outside of pad frame — change media if needed.
If water is coming out fan, check for leaks in water distribution hoses and/or leaks at hose connections to spreaders
Be sure there is at least 4 inches of space for rear panel free from wall or other obstruction. This could make the side panels release water to airstream due to increased air velocity through the sides.
Spreaders may have scale buildup allowing water to pool and spill over into airstream—Clean spreaders.
