SPX 800 - Manual

Before Start-up Safety Temporary safety barricades should be placed around any exposed openings in the operating (or nonoperating) tower, safety harnesses should be worn by personnel where appropriate, and other safety precautions should be taken in compliance with OSHA regulations and standards. Cl...

Before Start-up See Geareducer Service Manual for oil filling procedure and list of recommended lubricants. • Rotate fan by hand to be sure of free rotation and ample tip clearance. See Marley Fan Service Manual . • Check motor insulation with a “Megger.” See maintenance section of Marley Electric M...

Initial Starting Procedure 1— Fill the cold water basin and circulating water system to a level 1/2” (13 mm) below the overflow. 2— Bypass valve should be closed unless start-up is in cold weather. (See Routine Starting Procedure on page 8.) 3— Prime and start the circulating water pumps one at a ti...

Operation ➠ Tower Performance The following is intended to serve as a guideline for the operation of this counterflow mechanical draft cooling tower. The owner may use this infor-mation to develop preliminary operating procedures. As operational experi-ence with the system accumulates, more definiti...

10 Operation When changing fan direction of rotation, allow a minimum of two minutes time delay before energizing the fan motor. Hot Water Distribution System Hot water from the process flows through an inlet to each cell, which sup-plies a distribution header and a system of branch arms and nozzles...

11 Freezing Weather Operation During periods of low ambient air temperatures, °F to 0°F (°C to °C) or below, it is advisable to maintain the cold water temperature at or above 0°F (1°C) to retard the formation of ice and to assist in its control. The methods used in Minimizing Tower Energy Use, desc...

1 Freezing Weather Operation • Under extended extreme cold conditions, it may be necessary to operate the fan in reverse. This forces warm air out through the air inlets, melt-ing any accumulated ice. Reversal may be at either full or half speed; however, full speed is recommended if adequate heat l...

1 Temperature Control and Energy Management ➠ The wet-bulb temperature of the ambient air varies significantly on a daily basis, and considerably from season to season. As the wet-bulb temperature reduces, the tower becomes capable of producing colder and colder water—or it becomes capable of produc...

1 Maintenance ➠ Well maintained equipment gives the best operating results and the least maintenance cost. A regular inspection schedule is recommended to insure effective safe operation of the cooling tower. Use the Inspection and Maintenance Schedule on page 25 to obtain continuously good performa...

1 Cleaning Any evaporative-type cooling tower must be thoroughly cleaned on a regular basis to minimize the growth of bacteria, including Legionella Pneumophilla, to avoid the risk of sickness or death. Service person-nel must wear proper personal protective equipment. Do NOT attempt any service unl...

1 Blowdown Blowdown, or bleed-off is the continuous removal of a portion of the water from the circulating system. It is used to prevent dissolved solids from concentrating to the point where they will form scale. The amount of blowdown required depends upon the cooling range (design hot water tempe...

Troubleshooting Remedy 1. Check power at starter. Correct any bad connections be- tween the control apparatus and the motor. 2. Check starter contacts and control circuit. Reset overloads, close contacts, reset tripped switches, or replace failed control switches. 3. If power is not on all leads at ...

The tower has been designed to provide a safe working environment while either operating or shut down. The ultimate responsibility for safety rests with the Operator and Owner. When flow to the tower is shut off or when portions of the tower require maintenance, temporary safety barricades may be re...
