This includes piping, ductwork, conduit, and electrical connections. These items must be flexibly attached to the Evapco unit so as not to transmit additional loads to the equipment as a result of seismic or wind forces. - Page 6 Closed hydronic systems connected to either a closed-circuit cooler or dry cooler should be pre-cleaned and flushed to remove debris, grease, flash rust, oil, and other suspended solids prior to operation. Evapco recommends the use of inhibitor chemistry or inhibited glycol to minimize corrosion and scale during normal operation. EVAPCO recommends...

Page 9: Seasonal Shut-Down Checklist
Seasonal Shut-Down Checklist When the system is to be shut down for an extended period of time, the following services should be performed. The evaporative cooling unit cold water basin should be drained 2. The cold water basin should be flushed and cleaned with the suction strainer screens in place. 3. -

Feed grease slowly into the bearings or the seals may be damaged. A hand grease gun is recommended for this process. When introducing new grease, all grease should be purged from the bearings. Most EVAPCO units are supplied with extended grease lines to allow easy lubrication of the fan shaft bearings as shown in Table 1. Unit Description... -
Page 12: Fan Belt Adjustment
Fan Belt Adjustment (Direct drive units do not require any adjustment) The fan belt tension should be checked at start up and again after the first 24 hours of operation to correct for any initial stretch. To properly adjust the belt tension, position the fan motor so that the fan belt will deflect approximately 3/8” when moderate pressure is applied midway between the sheaves. - Page 13 Induced Draft – On induced draft belt driven units provided with externally mounted motors, see Figure 3. Figure 3 – Externally Mounted Motor, Induced Draft On induced draft belt driven units with internally mounted motors (10, 12, 14, 20, 24 and 28 foot wide units). PHC-S, L and D Units, a motor adjustment tool is provided on the adjustment nut.

The type of motor, manufacturer of the VFD, motor lead lengths (between the motor and the VFD), conduit runs and grounding can dramatically affect the response and life of the motor. Select a high quality VFD that is compatible with the fan motor(s) in the EVAPCO unit(s). -
Page 16: Two-Speed Motors
Repeat from full speed to minimum speed. Should vibration-inducing frequencies exist, the run-up and run- down test will isolate the resonant frequencies which then must then be locked-out in the VFD programming. For more details on the use of variable frequency drives, please download a copy of EVAPCO’s Engineering Bulletin 39 from evapco.com. -
Page 17: Recirculated Water System - Routine Maintenance
Recirculated Water System - Routine Maintenance Suction Strainer in Cold Water Basin The pan strainer as shown in Figures 10 through 14 should be removed and cleaned monthly or as often as necessary. The suction strainer is the first line of defense in keeping debris out of the system. Make certain that the strainer is properly located over the pump suction, alongside the anti-vortexing hood. -
Page 18: Cold Water Basin
Cold Water Basin The cold water basin should be flushed out quarterly, and checked monthly or more often if necessary, to remove any accumulation of dirt or sediment which normally collects in the basin. Sediment can become corrosive and cause deterioration of basin materials. When flushing the basin, it is important to keep the suction strainers in place to prevent any sediment from entering the system. -

Re-passivation may be required at any time in the service life of the equipment if an upset condition occurs which destabilizes the passivated zinc surface. For more information on passivation and white rust, please download a copy of EVAPCO’s Engineering Bulletin 36A at evapco.com. -
Page 22: Water Chemistry Parameters
Evapco does not recommend the routine use of acid due to the destructive consequences of improper feeding; however, if acid is used as part of the site specific treatment protocol, it should be pre-diluted prior to introduction into the cooling water and fed by automated equipment to an area of the system which ensures adequate mixing. -
Page 23: Gray Water And Reclaimed Water
During operation, off-line cleaning of evaporative cooling equipment should be undertaken on a regular basis. Inspections should be undertaken on a regular basis and should include both monitoring of microbial populations via culturing techniques and visual inspections for evidence of biofouling. Additionally, drift eliminators should be inspected and maintained in good operation condition. Service personnel must wear proper protective equipment (including approved respiratory protection equipment) while undertaking such cleaning efforts or any other maintenance efforts on evaporative cooling equipment. -
Page 24: Cold Weather Operation
Cold Weather Operation EVAPCO counterflow evaporative cooling equipment is well suited to operate in cold weather conditions. The counterflow design encases the heat transfer media (fill and/or coils) completely, and protects it from the outside elements such as wind which can cause freezing in the unit. - Page 25 Evaporative Condenser Closed Circuit Cooler Required Inlet Model Number Footprint Pressure (psi) ATC-E Products eco-ATC-A Products ATWB, eco-ATW & eco-ATWE Products 50E to 165E 122A to 263A 3’ and 4’ wide units** 170E to 247E 160A to 326A 8.5’x7.5’ 218E to 305E 205A to 504A 8.5’x9’...

Page 26: Freeze Protection Of Closed Circuit Cooler Coils
Freeze Protection of Closed Circuit Cooler Coils The simplest and most effective way of protecting the heat exchanger coil from freezing is to use an inhibited ethylene or propylene glycol anti-freeze. If this is not possible, an auxiliary heat load and minimum flow rate must be maintained on the coil at all times so that the water temperature does not drop below 50°F when the cooler is shut down. -
Page 27: Unit Accessories
It is very important to maintain close control of the cooler or condenser during winter operation. EVAPCO recommends that an absolute MINIMUM leaving water temperature of 42° F must be maintained for cooler applications. The higher the leaving temperature from the cooler or condenser, the lower the potential for ice formation. -
Page 28: Forced Draft Unit Capacity Control
However, low speed fan operation or variable frequency drives maintain a positive pressure in the unit which helps prevent ice formation on the fan drive components. For more information on cold weather operation, please download a copy of EVAPCO’s Engineering Bulletin 23 at evapco.com... -
Page 29: Troubleshooting
Troubleshooting Problem Possible Cause Remedy Overamping Fan Motors Reduction in air static 1. On a forced draft unit verify that the pump is on, and water is flowing pressure over the coil. If the pump is off, and the unit was not sized for dry operation, the motor may over-amp. - Page 30 Problem Possible Cause Remedy Scaled Inlet Louvers on Improper water treatment, Scale should not be removed using a power washer or wire brush AT Units insufficient bleed rates or because it could damage the louvers. Remove the louver assemblies and excessive cycling of the let them soak in the cold water basin of the unit.
- Page 31 These areas may include the coil connections, the cold water basin near the support steel, and around field erected platforms and catwalks. The rust spots can be removed with a good cleaning. EVAPCO recommends using either Naval Jelly or a good stainless steel cleaner, such as Mother’s Wax in conjunction with a Scotch-Brite pad.
