UNIT DOES NOT OPERATE -

1. Try switches at all speeds in both directions.
2. Check wire connections at switches, resistors, at wire nuts and at power supply.
3. Check fuse and charge level of battery.
4. If installed on trailer and operated on vehicle battery, check if inner connection correct.
5. With speed switch in OFF position, remove hood. Rotate fan by hand to check for interference with venturi opening, filter, pump rubbing on bottom of baffle or motor frozen.

INADEQUATE COOLING -

1. If no air flow, check above items 1 thru 5.
2. Check water level and water supply lines.
3. Check filter and pump. If dirty, clean as directed under maintenance.
4. Check to see pump cone tip is submerged in water and check 1/8” to 1/4” clearance between end of pump cone and bottom of baffle.
5. If water depth is less than 3/4”, depress float and observe if water is flowing thru the valve. Refer to Item 5, “Adjustment Procedures” to reset.

EXCESS VIBRATION -

1. Check fan blades and pump cone, rotating by hand. Note whether fan blades are broken or if cone set screw is loose. Are fan blades hitting filter or edge of venturi opening.
2. Check for loose screws, loose or deteriorated rubber motor mounting bushings. Replace if needed.

WATER LEAKAGE -

1. Check to make sure your unit is mounted on a portion of the roof level with the ground.
2. Check water level in unit. Refer to Item 5, “Adjustment Procedures,” for float valve adjustment.
3. Is drain plug installed and finger tight.
4. If leaking occurs while the vehicle is in motion, check baffle and clean any holes that may be clogged. See 12 in Installation Instructions.

EXCESS WATER CONSUMPTION -

1. Check items listed under Water Leakage above.
2. If rate of water consumption is not due to a leak but instead only during operation, remember, your TurboKOOL is providing cooling effect in proportion to the water consumed. Under conditions of high temperatures and low humidity, more water is used.
3. Severe driving conditions, such as rough roads or sharp turns cause excessive action of the float valve and allows the unit to overfill. See item 12 in Installation Instructions. (See How TurboKOOL Works.)


Recommended Routine Maintenance

1. Every 6 months, remove filter and clean by hosing down with water from outer surface, inward, or soak in a bucket of water to loosen dirt, etc. When your TurboKOOL is used in certain areas where the water has high alkali content, it may be desirable to clean more often. In these areas it may be to your advantage to have an extra filter.

2. Check spin-spray pump cone for caking of alkali and clean off with fine steel wool. Make sure holes at top of cone are not clogged. Since the inside of the cone pump can also become caked with alkali, you may wish to replace it periodically if performance drops.

3. The motor is equipped with factory oiled and sealed bearings. Under normal use, the bearings need no additional oil. If used in high alkali areas for long periods of time, a drop of oil in the lower bearing, (3 in 1 or sewing machine oil) will help. We recommend that you turn on your TurboKOOL at least once a month, and run for 5 minutes or more even during the off season.

4. Before the start of the warm season, check the condition of filter, grommets and wiring. Replace if cracked, brittle or deteriorating.

5. Drain water pan whenever your TurboKOOL is not being used.

6. Write to the factory for any parts required, or for assistance in case you encounter problems. Always include the Model No. and the Serial No. when writing. Both numbers are found on the I.D. label, see Fig.6, on the side of the body.
