CHILLED WATER SYSTEM Notice: Failure to maintain glycol levels can result in damage and void the warranty of your CTM units. Glycol must be added to the water after the bleeding process and any leaks have been fixed. You may use the brand of your choice, but make sure you follow the manufacturer's recommendations. - Page 20 CTM Marine Chilled Water Systems Installation & User Manual 1- In the diagram in page place close attention to the arrows and labels that indicate the direction where the water is flowing. Reversing this flow can cause problems to the system.
- Page 21 CTM Marine Chilled Water Systems Installation & User Manual INSULATION 1- Insulate straight lengths of pipe before a leak check. After everything checks during the leak test proceed to insulate joints or fittings. 2- The recommended material is a closed cell insulation of at least 0.75 inch (1.9 cm) thick. Insulation on areas that are not air conditioned may need thicker insulation.
- Page 22 While the chillers do not need flow controls, it's recommended that each air handler has one. Each CTM Air Handler comes with its own flow control valve installed. If the capacity of the air handler is greater than a 10% of the capacity of the chiller, a bypass of the flow control valve might be needed, If the pump cannot force the flow of the liquid through the chiller.
