OPERATION CHECKLIST

• Check all hose connections.

• Use a 12 gauge cord if the cord is shorter than 50 ft (15 m) or a 10 gauge cord if the cord is longer than 50 ft (15 m).

• Provide fresh air intake for the cooler and maintain a minimum clearance of 3 ft (0.9 m) behind the cooler.
  Do not operate the cooler in an enclosed space.

• Make sure the water source does not exceed 120 PSI (8 bar/827 kPa) of water pressure.

• Make sure the cooler’s reservoir is filled with water before turning on the pump. The pump automatically shuts off if the water level is too low.

• Flush new cooling media.
  1. Fill the cooler with water.
  2. Turn on the pump.
  3. Run the cooler without the fan running for 5 hours.

• Make sure the cooling media is evenly saturated by using the control valve to adjust the water flow. Do not completely open the control valve. This may flood the cooling media.

• Dry out the cooling media before shutting down the cooler. Turn off the pump and leave the fan running for 10 to 15 minutes.

• Drain and clean the cooler weekly. Remove the cooling media and rinse with a garden hose.

• To avoid scale and mineral buildup, use water treatment tablets periodically. Tablets are provided in the cooler’s reservoir according to the table below.  Every 3 months, add the specified number of tablets to the reservoir after cleaning. Additional tablets are available by calling 877-244-3267.

ASSEMBLY AND SETUP

CAUTION: Do not connect to a water source where water pressure exceeds 120 PSI (8 bar/827 kPa).
This will cause permanent damage to the cooler.
CAUTION: If using an extension cord, do not exceed the cord’s amperage ratings. Undersized extension cords create excessive drops in voltage, causing the electric motor to generate excess heat. This results in inefficient motor operation and premature motor failure and will void the warranty.

Installing the casters (Cool-Space® 300 only)

1. Locate the package of four (4) casters and sixteen (16) bolts and remove them from the box.
2. Lay the box on its side and carefully open the bottom of the box. Do not stand the box upside down.
3. Install the four casters using the bolts.
4. Stand cooler up on casters and remove the box.
   The cooler has been factory tested and is ready to use. Place the cooler on level ground with the casters locked to prevent inadvertent movement.

Connecting the water supply
The cooler comes equipped with a garden hose water source connection. Use a standard garden hose (not provided) to connect the water supply to the cooler.
Connecting the electrical supply
Plug the cooler into a fused or breaker-protected circuit. Refer to the tables below for circuit size and extension cord requirements. Cool-Space 500 models cannot be connected to a GFCI outlet.

OPERATION

The cooler must be placed on level ground to operate correctly. Evaporative coolers create an oval-shaped air pattern. Obstacles such as racks and workbenches may interfere with airflow. Position the cooler so that interruption of the air pattern is minimized. Multiple coolers may be required to cover larger areas.
There are three major factors to consider when determining where to place the cooler.

1. Fresh Air Supply. The inlet side of the cooler (pad side) requires a constant, uninterrupted supply of fresh air for maximum performance. A distance of 3 ft  (0.9 m) of clear space to any obstructions at the rear or inlet side of the cooler is recommended.
2. Discharge Airflow. The cool air discharged from the cooler should be free from obstruction to promote air circulation in order to maximize the cooling zone.
3. Ventilation. Adequate ventilation is needed to ensure the cooler does not recirculate air that has already been through the evaporative cooling process.

Operating the cooler

1. Fill the reservoir
   After connecting the cooler to a water source, turn the water supply valve on to fill the cooler with water. The float valve will shut of the water flow when the sump is full.

2. Turn on the pump
   When starting the cooler for the first time or after installing new cooling media, turn on the pump and flush the cooling media for 5 hours without the fan running and with the flow control valve fully opened. On initial startup, the cooling media will take a few hours to become fully saturated. During this time,  the media may produce an odor. This odor will dissipate over time. For best results, change the water in the reservoir a few times.

3. Turn on the fan and adjust the water flow
   Set the fan switch to the ON position and adjust the speed to your preferred setting. Adjust the water flow with the flow control valve until water streams over the pads. Do not flood the pads with water. You should see several 1″ to 2″ (25 to 51 mm) wide dry streaks on the face of the pads. If dry streaks grow wider, adjust flow to allow more water.
   The pump automatically shuts of if the water level is too low. If the pump will not start or stops running, refill the cooler with water. The pump may take up to five (5) minutes to reset after the cooler is refilled.

MAINTENANCE AND STORAGE

WARNING: ELECTRICAL SHOCK HAZARD. Disconnect the power supply before performing service or maintenance. Failure to do so may result in serious injury or death.

Removing the cooling media
Remove the cooling pads to access the inside of the cooler.

1. Remove the bolts connecting the pad retainer bar (pad side) from the housing.
2. Cool-Space® 400 and 500 models: Remove top pads.
3. Starting with the center pad(s), tilt pads from the top and lift out of the cooler.

NOTE: Reinstall pads correctly according to the markings on the pads.

Daily maintenance
After each use, turn off the pump for about 15 minutes before turning the fan of to allow the pads to drain and dry out. This controls mildew and bacteria growth for a long and efficient pad life. Drain the water from the cooler if it will be unused for a prolonged period of time.

Periodic maintenance
The cooling pads act as a filter to remove dust and other particles from the incoming air stream. The collected particles and any water impurities will flow into the sump and collect there. To keep the cooler operating at peak efficiency, keep the cooling media and sump clear of debris.

Draining the water sump
Depending on how often you operate the cooler, drain the sump anywhere from every week for heavy use to monthly for light use.

1. Close the water flow valve and open the drain valve or remove the drain plug located at bottom of the reservoir.
2. Run the pump until the sump is dry, and then immediately shut off the pump.
3. Turn the cooler off and disconnect the power supply.
4. Remove cooling pads.
5. Clean out the reservoir with either a towel or wet/dry vacuum.
6. Remove the water spray bar and its plug. Ensure holes are free of debris.
7. Reinstall pads and pad retainer.

Using water treatment tablets
To avoid scale and mineral buildup, use water treatment tablets periodically. Tablets are provided in the cooler’s reservoir according to the table below. Every 3  months, add the specified number of tablets to the reservoir after cleaning. Additional tablets are available by calling 877-244-3267.

Cleaning the cooling media
Ensure the cooling pads are kept clean and dust-free. Dust and other particles have an adverse effect on the pads’ ability to introduce water into the air stream. If the pad surface is dirty, clean with a soft brush and water. Never use bleach.

Storage

1. Remove cooling pads and clean with a soft brush and water to remove dust and debris.
2. Drain sump and wipe dry.
3. Store the cooler in a dry area and cover to prevent dust buildup.

MAINTENANCE CHECKLIST

Spring cleaning

• Remove the cooling media and clean out any debris in the water pan at the bottom of the cooler.
• Remove the distribution tube from the mounting clips. Remove the plug at the end of the tube and flush out. Clean the distribution holes with a small brush and flush with water to verify all holes are clear.
• If the cooling media is heavily stained with minerals or is damaged, replace the media. Replacement cooling media is available at bigassfans.com. Verify the media is installed correctly with the arrows on the side.
• Connect the water line and turn on the water supply. Check the float valve and make sure it is operating properly. Verify that the float valve is shutting the water of before walking away.
• Switch on the fan motor and pump. Make sure the cooling media is evenly saturated with water by using the flow control valve to adjust the water flow.  Small dry streaks are acceptable.

Mid-summer checkup

• Make sure the float valve is working properly. If the valve sticks, the water will run continuously and flood the reservoir. If this occurs, install a new float valve or contact Customer Service.

• Check all other working parts for cracks or damage, including the pump, fan motor, and fan belt.

• Check the condition of the cooling media. The cooler runs most efficiently when the media is clean.
  If the media has a heavy accumulation of mineral deposits, replace it.

• Use the drain valve to empty the reservoir. Remove any debris.

Winterize

• Clean the minerals from the reservoir. Vinegar can be used to dissolve buildup. Flush out the
  reservoir through the drain plug.

• Inspect the water distribution tube for clogged holes. Clean as necessary.

• To prevent freezing in the cooler’s waterline, disconnect the water supply, and then open both valves on the side of the cooler to dry out the reservoir.

• Use a storage cover to protect your cooler and keep it clean.
