Maintenance

Weekly: Inspect for bacterial growth and general operation conditions. Bacterial growth should be reported to your water treatment expert for immediate attention.

Monthly (Weekly at start up): Observe, touch, and listen to the fluid cooler. Become accustomed to its normal appearance, sound, and level of vibration. Abnormal aspects relating to the rotating equipment should be considered reason to shut down the fluid cooler until the problem can be located and corrected. Observe operation of the motor, coupling (or drive shaft), Geareducer, if equipped and fan. Become familiar with the normal operating temperature of the motor(s), as well as the sight and sound of all components as a whole.

If equipped, check for Geareducer oil leaks. Check the Geareducer as well as any optional oil lines to external oil dipstick/sight glass.

Inspect louvers, drift eliminators and basin trash screens and remove any debris or scale which may have accumulated. Replace any damaged or worn out components. Use of high-pressure water may damage the eliminator and louver material.

Clean the Thermal Equalizer™ trays above the coil removing any accu- mulated debris or scale.

Observe operation of the float valve. Depress the operating lever to make sure that the valve is operating freely. Inspect the suction screen for plug- ging. Remove any debris that may have accumulated.

Check for any buildup of silt on the floor of the collection basin. Mentally make note of the amount, if any, so future inspections will enable you to determine the rate at which it is forming.

Every 3 months: If equipped, lubricate fan shaft bearings. While rotating equipment by hand, grease the bearings until a bead forms around the seals—a maximum charge of 0.30 ounces (MHF702-MHF704) and 1.4 ounces (MHF706-MHF707) is recommended. Mobil SHC 460 grease is recommended.

Semi-Annually:If equipped, check the belt tension and condition.

If equipped, check Geareducer oil level. Shut down the unit and allow 5 minutes for the oil level to stabilize. Add oil if required.

If equipped with dampers, lubricate jack shaft bearings and tiebar linkage with silicone lubricant. If dampers are equipped with pneumatic or electric actuators, the manufacturer's recommended maintenance procedures should be observed. If dampers are exposed to heavy dust-laden air, oc- casional flushing of the bearings with water is recommended.
