Rigging and Lifting Procedures Rigging Each module should be lifted using lift straps threaded through the steel base cutouts and a spreader bar. Note: If no spreader bar is used, damage to the module may occur. Figure 1 Figure 2 Lifting Strap Lifting Strap Spreader Bar Spreader Bar Spreader Bar Lifting and Transporting Modules Pallet jacks or forklifts are required for lifting and transporting the module. Each module has base cutouts provided for ease of maneuverability.
Mounting Rail and Vibration Isolation ClimaCool recommends locking down the chiller to a concrete base or to (3) 4” base mounting rails using the six bolt holes provided in each base pan. Due to the low vibration of the modules, ClimaCool does not require the application of spring isolators or pads. Should isolators or pads be desired, install in accordance with Figures 4 and 5.

For brazed plate, allow 36” clearance for electrical panels and 30” clearance for rear access to modules. 2. For shell and tube, allow 60” clearance for electrical panels and 30” clearance for rear access to modules. 3. Allow a minimum of 36” height clearance for service. 4. Local building or electrical codes may require additional clearance.
Water Piping ClimaCool provides four (4) temperature sensors and wells with each chiller system configured by the CoolLogic Control System. They must be field installed 36” - 60” away from the bank and before the strainer on the chilled water inlet, chilled water outlet, condenser water inlet and condenser water outlet (See Water Piping Configuration – page 12). Note: Sensors must be fully inserted into the well to obtain proper readings.
Water Piping Modules can be designated for fixed bypass for heating, cooling and source flow, however, this limits the number of modules remaining for that duty. Also, with a module acting as a bypass increased wear of heat exchangers may be caused by abrasion from bypass flow. ClimaCool offers two types of water header bypass kits, direct return (Figure 6) and reverse return (Figure 7) as shown on page 10.

Filling the Water System It is imperative that the water systems are free from debris prior to initial operation. See Water Treatment for a comprehensive list of precautions on page 15. Filling, Purging and Leak Testing the System After the water systems have been properly installed, visually inspect all joints for tightness. If the chiller is to be installed in an existing system, the cleanliness of the existing system can be judged from the operating conditions of the present machines.
Water Treatment Water quality is of the utmost importance for the proper care and maintenance of the modular chiller system. Proper water treatment is a specialized industry and it is recommended to consult an expert in this field to analyze the water for compliance with the water quality parameters listed in Table 1. The materials exposed to the water are type 316 stainless steel, pure copper and carbon steel. Other materials may exist external to the ClimaCool chiller.
Water Temperature Requirements Condenser Water Temperature Chilled Water Temperature The condensers are designed to operate most efficiently at lower entering water temperatures for lower power consumption. The expansion valve, however, relies on the pressure difference across the valve to drive the liquid refrigerant through.

Refrigeration System Re-Processing and Charging Conforming to local and national codes is the responsibility of the service technician or installing contractor. The service technician should be familiar with the following codes: • ASHRAE Standard Safety Code for Mechanical Refrigeration, ANSI/ASHRAE 15-1978 • American National Standard Code for Pressure Piping, ANSI B31.5-1974 reaches zero psig or slightly higher. Then, repeat the entire evacuation process described above.
Refrigeration System Re-Processing and Charging Operation This valve is a step motor operated electric expansion valves. Step motors are designed to provide discrete segments of angular motion, or rotation, in response to an electronically generated signal. The step motor used in this valve is a 12-volt DC, two-phase, bi-polar, permanent magnet rotor type. Motor rotation is converted to linear motion by the use of a lead screw and threaded drive coupling.
Refrigeration System Re-Processing and Charging Interface Board Factory installed interface board allows externally supplied control signals to control electronic expansion valve. Figure 18 - Interface Board The routine will require approximately 8 seconds for the interface board 1, 16 seconds for the interface board 2 and interface board 3 and 32 seconds for the interface board 6. The valve will not respond to input signals during this time.
Refrigeration System Re-Processing and Charging Test the Valve The resistance of the motor winding may be tested without opening the system. 1. Remove power from the external controller and/or interface board. 2. Remove the valve leads from interface board. 3. Measure the resistance between the black and white leads of the valve. Resistance should be 75 ohms with the valve at room temperature or approximately 65 ohms if the valve is at -40°F. 4.
Options and Accessories Shell and Tube Condenser Water Header Bypass Factory installed cleanable shell and tube condenser with enhanced copper tube geometry. Provides removable, epoxy coated, water plates to facilitate cleaning. Contact factory for application parameters. Factory installed to prevent deadheading the pump, a water header bypass may be utilized and is mandatory when using motorized valves.
Stainless Steel Strainer Option Figure 20 - Stainless Steel Strainer Strainer Installation Recommendations The following the guidelines are recommended when installing the strainer: 1. 2. 3. Safety Considerations Prior to installation, this manual must be read carefully and all instruction understood. Personal injury or product damage can occur if the following safety precautions are overlooked or ignored.
Stainless Steel Strainer Option Table 2 Table 1 Figure 21 - Recommended Torquing Sequence Strainer 3CS 4CS 6CS 8CS 10CS Bolt Size Recommended Torque (ft. lbs) 5/16 3/8 1/2 1/2 5/8 - 60 15 45 45 80 (inches) 18 16 13 13 11 - 80 25 55 55 100 Note: The 3CS strainer torque is in lbs (not ft. lbs). Strainer Operation Periodically, it will be necessary to flush out the debris that is collected and settles to the bottom of the strainer reservoir.
Stainless Steel Strainer Option What Causes Water Hammer? Figure 22 Any action that can cause a rapid change in the velocity of the flow can set off a water hammer, such as closing a downstream valve, pump stoppage, etc. Typically, for short lengths of pipe (below 500 feet) downstream valves that are closed within 1/10th of a second can generate a water hammer. What Can Water Hammer Do? Pressure spikes from water hammer can raise fluid pressures to dangerously high values.
Stainless Steel Strainer Option Operation Instructions Water Resistance Flush valve line must be piped to atmospheric pressure such as an open floor drain. The flush line should not undergo any changes in elevation and should be sloped downward in the direction of drainage. Do not pipe the flush or drain line into a pressurized line. The valve and controller are water-resistant, but not water-proof. Do not install below ground level where the component can be submerged in water.
Stainless Steel Strainer Option When the differential set point is reached, both the audible and visual alarms will be triggered. It will remain engaged until both the alarm condition is corrected and the alarm-reset button is pressed (if the alarm-reset button is pressed but the differential pressure is beyond the set point, the alarms will re-engage immediately). After the strainer is cleaned and put back in service, the differential pressure should return to 1 psi.
“Y” Strainer Basket Strainer Before installing the “Y” strainer, ensure the pressure rating is correct for the system. If the end connections are threaded or designed for soldering or brazing, be sure the piping is straight and not at an angle or offset. If the strainer has flanged ends, be sure the flanges of the connecting IOM-MS-YStrainers piping are square with the pipe so that no undue stress is put on the strainer or piping when tightening the flange bolts.
