READ AND SAVE THESE INSTRUCTIONS WARNING: ELECTRICAL SHOCK HAZARD. Disconnect the power supply before performing service or maintenance. Failure to do so may result in serious injury or death. CAUTION: Use caution when troubleshooting or repairing electrical components. Ensure power is disconnected from the cooler before the pads or fan guard are removed to gain access to the fan. CAUTION: Repairs should be performed by a qualified technician.
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 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.
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.

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.

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.
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 cooler in a dry area and cover to prevent dust buildup. WWW.BIGASSFANS.
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.
TROUBLESHOOTING WARNING: ELECTRICAL SHOCK HAZARD. Disconnect the power supply before performing service or maintenance. Failure to do so may result in serious injury or death. CAUTION: Use caution when troubleshooting or repairing electrical components. Ensure power is disconnected from the cooler before the pads or fan guard are removed to gain access to the fan. Contact Customer Service for assistance with troubleshooting and replacement.
Water distribution system troubleshooting Issue Solution(s) Floor at side of cooler is wet. Water inlet hose is loose at supply hose or inlet hose is loose at bulkhead fitting. Tighten connections and/or replace hose washers. Float valve hose is loose at bulkhead fitting or at float valve. Tighten connections and/or replace hose washers. Water overflows from reservoir or is spitting through fan. Water pressure is too high to allow float valve to shut off (120 PSI/8 bar/827 kPa max).
Fan system troubleshooting Issue Solution(s) Fan will not run and makes no sound. Check power cord, extension cord, switches, and circuit breaker. • Reconnect power or extension cord. • Reset breaker. Fan will not run and makes humming sound. Blade is in contact with shroud. Re-center blade hub. Motor stall (will not turn by hand). Replace motor. Motor stall. Replace motor. Breaker trips or fuse blows when fan starts. Check power source. Refer to page 2 for electrical requirements.
Error codes (Cool-Space® 500 only) Error Solution(s) E1 - Voltage Self-Inspection Error • Try a different circuit. • Replace the panel. E2 - Overcurrent Protection Current draw is too high. • Check extension cord size. • Check that motor spins freely. • Check that airflow is not obstructed. E3 - Under Voltage Protection Supply voltage is too low (< 100 V). • Try a different circuit. • Install a voltage regulator. E4 - Over Voltage Protection Supply voltage is too high (> 130 V).
PUMP REPLACEMENT WARNING: ELECTRICAL SHOCK HAZARD. Disconnect the power supply before performing service or maintenance. Failure to do so may result in serious injury or death. 1. Unscrew fitting from pump. 2. Unplug cord from top of pump by removing the two (2) screws. 3. Remove pump from water sump and install new pump. 4. Perform the steps above in reverse to reconnect the wiring, lift the pump bracket, and reconnect the hose. 5.
