Any such deviation, change or modification shall be the responsibility of the party or parties making such deviation, change or modification. SPX Cool- ing Technologies, Inc. expressly disclaims all liability for any such deviation, change or modification. -
Page 4: Location
Those are only some of the safety issues that may arise in the design process. SPX strongly recommends that you consult a safety engi- neer to be sure that all safety considerations have been addressed. Location Space available around the evaporative condenser should be as generous as possible to promote ease of maintenance and to permit freedom of airflow into and through the evaporative condenser. -
Page 5: Hoisting
receiving and hoisting Hoisting All LC evaporative condenser models use reinforced hoisting clips located near the air inlet (bottom section) of the equipment for overhead lifting and handling of assembled shipping modules. A spreader bar should always be used at the top of the unit to help balance the load and prevent damage to the top section —... -
Page 6: Installation
installation Installation These installation instructions are intended to help you prepare Note before your evaporative condenser arrives. If discrepancies exist between these instructions and those shipped with the evaporative condenser, the instructions shipped with the evaporative condenser will govern. 1. Prior to placement of the evaporative condenser, confirm that the support- ing platform is level, and that the anchor bolt holes are correctly located in accordance with Recold drawings. -
Page 7: Control Panel
Connect electrical supply wiring to the main control panel in accordance with wiring diagram(s) and instructions included with the control panel. For maintenance/safety purposes, SPX recommends a lockout type Warning disconnect switch for all mechanical equipment. Branch circuit protection must be provided for control panels and must meet or exceed all NEC and local codes. -
Page 8: Mechanical Equipment
operation Mechanical Equipment Always use caution when working near electrical and mechanical Warning components. Always shut off electrical power to the evaporative condenser fan motor prior to performing any maintenance on the evaporative condenser. Any electrical switches should be locked out and tagged out to prevent others from turning the power back on. - Page 9 operation 2. Do NOT attempt any service unless the fan motor is locked out. 3. Remove any and all accumulated debris from the evaporative condenser. Pay particular attention to inside areas of collection water basin, distribution water system, louvers and drift eliminators. Make sure that recirculating water suction screens are clear and properly installed.

Page 10: Operation
operation After biocidal pretreatment has been successfully completed, cooling water may be circulated over the coil with the fan off. When biocidal treatment has been maintained at a satisfactory level for at least six hours, the fan may be turned on and the system returned to service. -
Page 11: Dry Operation
operation Dry Operation Also refer to the Freezing Weather Operation section. Note LC evaporative condenser models may be operated dry without recirculating water during colder weather as heat load and ambient conditions permit. If dry operation is intended and the recirculating water is at risk of freezing, the recirculating pump should be turned off, and the water in the collection basin, pump and make-up supply piping should be drained. - Page 12 operation Intermittent Freezing Weather Operation: If periods of shutdown (nights, weekends, etc.) occur during freezing weather, measures must be taken to prevent the water in the cold water basin and all exposed pipework from freezing. Several methods are used to combat this, including Recold automatic basin heater systems and pump freeze protec- tion systems.

Page 13: Water Quality And Blowdown
maintenance Water Quality and Blowdown Maintaining Water Quality: Galvanized steel structural and casing components used in LC evaporative condensers have been galvanized with a heavy zinc coating averaging 2.0 mils in thickness. Other materials used (PVC fill, drift eliminators, and louvers, aluminum fans, etc.) are selected to offer maximum service life in a “normal”... - Page 14 maintenance Blowdown: Evaporative heat exchange equipment functions by continuously causing a por- tion of the water circulated over the heat transfer media to evaporate. Although the water lost by evaporation is replenished by the makeup system, it exits the evaporative condenser as pure water, leaving behind its burden of dissolved solids to concentrate in the remaining water.

Before op- erating the evaporative condenser, the water management plan and maintenance procedures must be in place and regularly practiced. In addition, the following steps are recommended: Do NOT attempt any service unless the fan motor is locked out. •... -
Page 16: Access Doors
maintenance Collection basin floor has uneven surfaces and has the potential to Caution be slippery. Care should be taken if entering the basin. Louver edges can be very sharp and could cut skin if proper protec- Caution tion is not used. Always wear gloves and sleeves when handling louver packs. -
Page 17: Drift Eliminator Removal And Replacement
maintenance Drift Eliminator Removal and Replacement: Eliminator edges can be very sharp and can cut skin if proper pro- Caution tection is not used. Always wear gloves and sleeves when handling eliminator packs. The drift eliminators may be removed for cleaning, replacement or access to the distribution system. -
Page 18: Routine Maintenance
maintenance Routine Maintenance: Included with the instruction packet are separate User Manuals on major op- erating components of the evaporative condenser, and it is recommended that you read them thoroughly. Where discrepancies may exist, the separate User Manuals will take precedence. The following is recommended as a minimum routine of scheduled maintenance: Always shut off electrical power to the evaporative condenser fan Warning... - Page 19 maintenance Check for any buildup of silt on the floor of the collection basin. Flush and remove excessive buildup. View the water pattern on the heat transfer coil. If there are dry spots on the coil or inconsistent coverage, this may be evidence of a clogged nozzle. Inspect nozzles for blockage.

Page 20: Seasonal Shutdown Instructions
maintenance Seasonal Shutdown Instructions When the system is to be shut down for an extended period of time, it is rec- ommended that the recirculating water system be drained. Leave the basin and pump drains open. During shutdown, follow recommendations in the Evaporative Condenser Inspection and Maintenance section of this manual before attempting repairs. -
Page 21: Long Term Storage Procedures
maintenance Long Term Storage Procedures For protection of non-operating equipment for more than three months. After installation of the evaporative condenser and completion of the pre-startup instructions, the operational availability of equipment will last for a maximum period of three months. Ensure that the evaporative condenser is completely drained of all water. - Page 22 Periodic Maintenance You may wish to contract with SPX Cooling for regularly scheduled visits for the purpose of inspecting and reporting your evaporative condenser’s condition, to make recommendations intended to prevent emergencies and to perform maintenance considered outside the norm.
- Page 23 Evaporative Condenser Rebuilding SPX routinely rebuilds and upgrades evaporative condensers, fluid coolers and cooling towers of all materials and manufacture. If your product ever reaches the limit of its service life, we recommend that you investigate the cost of re- building before you routinely order a new replacement evaporative condenser.
