Operating Instructions

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.

Inspection:
After unpacking your evaporative cooler, carefully inspect for any damage that may have occurred during transit. Inspect for loose, missing or damaged.

Key Operational Points:

1. Your cooler must be positioned in front of an open window or door if it is to operate effectively.
2. Always ensure that there is another open window or door through which the air can exhaust from the room.
3. Ensure the filter is kept clean throughout the summer season.
4. At the end of each day run your cooler on FAN ONLY for 30 minutes to dry out the filter.
5. Prior to putting your cooler away for winter, always:
   1. Drain the tank and wipe out clean.
   2. Clean the filter
   3. Reassemble and run on FAN ONLY for 30 minutes to dry out the filter.

Location! Location! 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.

Remember your cooler has been designed to operate even if it runs out of water. No damage will be caused to the pump if cooler 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.
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.
7. Assure that all power cords do not come in contact with any sharp edges, hot surfaces or chemicals. Immediately replace any damaged parts.
8. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

Cooler Set Up and Operation

1. Lay the cooler down
   
2. Unscrew two screws, remove the bottom panel
   
3. Take out casters(x4), Screws(x16), flat washer(x16) and garden hose adapter(x1)
   
4. Install the garden hose adapter to the float valve assembly
   
5. Install 4 casters
   
6. Your cooler is ready to go!
   

Hessaire Coolers are 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 Xel50 Media 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)

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 (supplied by customer), or a direct water line. (Parts for direct connection can be obtained at any hardware store.) 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

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 Hessaire cooler into any 115 volt power supply. It is permissible to use extension cords when needed. It is not recommended to use a GFCI circuit usually found in garage or patio areas. These outlets/circuits are sensitive and may trip inadvertently to the cooler in normal operation. Should that be the only power supply please be aware of this and if the GFCI trips simply reset it.

Cooler Maintenance

(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 Hessaire Mobile 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, same for the side 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 Xel50 Cooling Media.
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 OEM Xel50 media 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. Xel50 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. YOU'RE DONE... It's that easy.
4. Reinstall the back panel and you are ready to use the cooler again.

Pump Maintenance and Replacement. (Disconnect power supply before this procedure.)
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. And YOU'RE DONE!

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.
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.
