Addendum No. 1 Wicomico County Purchasing 125 N. Division St. Room B-3 Salisbury, MD 21801 Ph. 410-548-4805 Fax 410-334-3130 Addendum # 1 Date: 3/11/2016 Bid: Chiller Removal and Installation A Pre-Bid Walkthrough was held at the job site on March 8, 2016 at 11:00 AM. As the walkthrough was mandatory, only vendors who attended this meeting will be allowed to bid on this project. If a submission is received from another firm which did not attend this meeting, the submission will be marked as nonresponsive. The sign-in sheet for this meeting follows this addendum. The following are notes, answers to questions, and clarifications made at this particular meeting. Huston Crane Services Inc. and Aerial Crane Inc. are two crane companies suggested for the bidders uses. These companies have completed business for the Wicomico County Department of Corrections in the past. The new chiller is of the rear mounted type, while the existing chiller is side mounted. The piping should be constructed to accommodate this layout. The existing supports for piping are requested to be used. These supports should be modified as needed for the installation of the new chiller. New 4 supply lines are to be insulated and have protected return. The linear footage for the heat trace line is 135 feet and 120/20 amp. The electrical should be connected to a brand new, standalone circuit within the existing electrical panel. There are no controls required, WCDC will include these. The existing hold-down anchoring should be modified on site, by the contractor, to accommodate the new chiller. Any paving damages should be the responsibility of the crane company hired. New and larger fuses will be provided by WCDC, for the vendor to install. Production of the new chiller should take 4-6 weeks, and is currently on order. The chiller should be installed by June, 2016. A PDF of the Trane chiller follows this addendum. ARC water will flush the unit to ensure purified water flows. The strainer is built in to the new chiller. 1

Mechanical Specifications - Air-Cooled Scroll General Units are constructed of a galvanized steel frame with galvanized steel panels and access doors. Component surfaces are finished with a powder-coated paint. All paint meets the requirement for outdoor equipment of the U.S. Navy and other Federal Government Agencies. This paint finish is durable enough to withstand a 1000-consecutive-hour salt spray application in accordance with standard ASTMB117. Each unit ships with full operating charges of refrigerant and oil. Compressor and Motor The unit is equipped with four hermetic, direct-drive, 3600 rpm 60 Hz suction gas-cooled scroll compressors. The simple design has only three major moving parts and a completely enclosed compression chamber which leads to increased efficiency. Overload protection is internal to the compressors. The compressor includes: centrifugal oil pump, oil level sight glass and oil charging valve. Each compressor will have compressor heaters installed and properly sized to minimize the amount of liquid refrigerant present in the oil sump during off cycles. Unit-Mounted Starter The control panel is designed per UL 1995. The starter is in an across-the-line configuration, factory-mounted and fully pre-wired to the compressor motor and control panel. Typically, Trane scroll compressors are up to full speed in one second when started across-the-line. A factory-installed, factory-wired 820 VA control power transformer provides all unit control power (120 Vac secondary) and Trane CH530 module power (24 Vac secondary). A molded case standard interrupting capacity circuit breaker, factory pre-wired with terminal block power connections and equipped with a lockable external operator handle, is available to disconnect the chiller from main power. Power Connection Power connections include main three-phase power and one separate 115V, 20 amp customer provided single phase power connection is required to power the heaters (if used for freeze protection). Short circuit current rating of 5 ka is provided. Evaporator Braze plate evaporator is made of stainless steel with copper as the braze material. It is designed to withstand a refrigerant side working pressure of 430 psig (29.6 bars) and a waterside working pressure of 150 psig (10.5 bars). Evaporator is tested at 1.1 times maximum allowable refrigerant side working pressure and 1.5 times maximum allowable water side working pressure. It has one water pass. A water strainer and a flow switch are factory installed. Immersion heaters protect the evaporator to an ambient of -20 F (-29 C). All evaporators have grooved pipe connections. Note: An additional 115V, 20 amp field provided single phase power connection is required to power the heaters (if used for freeze protection). Condenser Air-cooled condenser coils have lanced aluminum fins mechanically bonded to internally-finned copper tubing. The condenser coil has an integral subcooling circuit. The maximum allowable working pressure of the condenser is 650 psig (44.8 bars). Condensers are factory proof and leak tested at 715 psig (49.3 bars). Direct-drive vertical discharge condenser fans are balanced and individually protected. Three-phase condenser fan motors with permanently lubricated ball bearings and external thermal overload protection are provided. A variable speed drive on the first fan of each circuit allows the unit to start and operate with ambient temperatures between 0.0 F and 125.0 F. Refrigerant Circuits The unit has dual refrigerant circuits. Each refrigerant circuit has Trane scroll compressors piped in parallel with a passive oil management system. A passive oil management system maintains proper oil levels within compressors and Equipment Submittal Page 7 of 23
has no moving parts. Each refrigerant circuit includes filter drier, electronic expansion valve, liquid line and discharge service valves. Capacity modulation is achieved by turning compressors on and off. The unit has four capacity stages. Unit Controls The microprocessor-based control panel is factory-installed and factory-tested. The control system is powered by a pre-wired control power transformer, and will turn on and off compressors to meet the load. Microprocessor-based chilled water reset based on return water is standard. The unit comes with a factory installed flow switch. The Trane CH530 microprocessor automatically acts to prevent unit shutdown due to abnormal operating conditions associated with low evaporator refrigerant temperature and high condensing temperature. If an abnormal operating condition continues and the protective limit is reached, the machine will shut down. The panel includes machine protection for the following conditions: low evaporator refrigerant temperature and pressure, high condenser refrigerant pressure, critical sensor or detection circuit faults, lost communication between modules, phase loss, phase reversal, over temperature protection, external and local emergency stop, and loss of evaporator water flow. When a fault is detected, the control system conducts more than 100 diagnostic checks and displays results. The display will identify the fault, indicate date, time, and operating mode at time of occurrence, and provide type of reset required and a help message. Data contained in available reports includes: water and air temperatures, refrigerant pressures and temperatures, flow switch status, EXV position, and compressor starts and run-time. All necessary settings and setpoints are programmed into the microprocessor-based controller via the operator interface. The controller is capable of receiving signals simultaneously from a variety of control sources, in any combination, and priority order of control sources can be programmed. Communications BACNet Interface allows the user to easily interface using BACNet MS/TP via a single twisted-pair wiring to a factory-installed and tested communication board. Comprehensive Acoustic Package Acoustical treatment for compressors is factory installed. Architectural Louvered Panels Louvered panels cover the complete condensing coil and service area beneath the condenser. Isolators Molded elastomeric isolators, sized to reduce vibration transmission to the supporting structure when the unit is installed, ship with the chiller. Equipment Submittal Page 8 of 23
