Shell-and-Tube Condenser Cleaning — The shelland- tube condenser tubes can be cleaned either mechanically or chemically. To clean them chemically, follow the procedure described in Brazed-Plate Cooler and Condenser Heat Exchanger Cleaning section above. To clean the condenser tubes manually: 1. Order tubing brushes (Carrier part no. KC21AH105). 2. Close the valves on the condenser and relieve condenser water pressure. BE SURE TO PROVIDE DRAINAGE TO PREVENT WATER DAMAGE. 3. Remove the condenser h

Systems can vary from one installation to another. These systems and procedures are meant for general guidelines only. The three most common types of systems are given below. Review these systems and decide which applies to your machine. Then follow the start-stop procedure given. NOTE: If machine has been shut down for more than 2 days, follow procedures under Start-Up After Limited Shutdown or Start-Up After Extended Shutdown. In all cases below, when machine starts, the white run light will

Throughout this publication, the chilled liquid will be water. Subjects covered are chilled water temperature control, condenser water temperature control, system design for steam and hot water machines, and general information. CHILLED WATER TEMPERATURE CONTROL The absorption machine is basically a water chiller that can be connected to any conventional open or closed system. However, circulation of chilled water must be continuous during operation of the machine and during the shutdown dilu

When operating this equipment, use good judgement and safety precautions to avoid damage to equipment and property or injury to personnel. Be sure you understand and follow the procedures and safety precautions contained in the machine instructions as well as those listed in this guide.

Be sure you understand and follow the procedures and safety precautions contained in the chiller instructions as well as those listed in this guide. DO NOT VENT refrigerant relief valves within a building. Outlet from rupture disc or relief valve must be vented outdoors in accordance with the latest edition of ANSI/ASHRAE 15 (American National Standards Institute/American Society of Heating, Refrigeration, and Air Conditioning Engineers). The accumulation of refrigerant in an enclosed space can

The refrigerant can be pumped for service work to either the chiller compressor vessel or chiller condenser vessel by using the optional pumpout system. If a pumpout storage tank is supplied, the refrigerant can be isolated in the storage tank. The following procedures describe how to transfer refrigerant from vessel to vessel and perform chiller evacuations. Always run the chiller cooler and condenser water pumps and always charge or transfer refrigerant as a gas when the chiller pressure is le
