Introduction

Read this manual thoroughly before operating or servicing this unit.

Warnings, Cautions, and Notices

Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions.

The three types of advisories are defined as follows:

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices.

Indicates a situation that could result in equipment or property-damage only accidents.

Important Environmental Concerns

Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs and HCFCs such as saturated or unsaturated HFCs and HCFCs.

Important Responsible Refrigerant Practices

Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified according to local rules. For the USA, the Federal Clean Air Act (Section

608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

Pre-Installation

ASHRAE Standard 15 Compliance

Trane recommends that indoor CenTraVac™ chiller installations fully meet or exceed the guidelines of the current version of ASHRAE Standard 15, in addition to any applicable national, state, or local requirements. This typically includes:

• A refrigerant monitor or detector that is capable of monitoring and alarming within the acceptable exposure level of the refrigerant, and that can actuate mechanical ventilation.

• Audible and visual alarms, activated by the refrigerant monitor, inside the equipment room and outside of every entrance.

• The equipment room should be properly vented to the outdoors, using mechanical ventilation that can be activated by the refrigerant monitor.

• The purge discharge and the rupture disk must be properly piped to the outdoors.

• If required by local or other codes, a self-contained breathing apparatus should be available in close proximity to the equipment room.

Refer to the latest copy of ASHRAE Standard 15 for specific guidelines. Trane assumes no responsibility for any economic, health, or environmental issues that may result from an equipment room’s design or function.

NNoottee:: The holding charge should register

approximately 5 psig (34.5 kPaG) at 72°F (22.2°C). Place a gauge on the access valve provided (indicated by arrow and circle in the following figure) on the refrigerant pump discharge line to verify the holding charge. If the charge has escaped, contact your local Trane sales office for instructions.

3. The loose parts box and isolator pads ship on top of the control panel box.

4. Check the oil sump sight glasses to verify that the sump was factory-charged with 9 gallons (34.1 L) of oil. If no oil level is visible, contact your local Trane sales office.

IImmppoorrttaanntt:: If isolation springs are installed, do NOT

block oil tank serviceability.

Figure 2. Refrigerant pump discharge line access valve

Unit Shipment

Inspect unit while it is still on the truck for any shipping damage. The chiller ships shrink-wrapped in a 0.010-in. (0.254 mm) recyclable film protective covering. Do NOT remove shrink-wrap for inspection! Inspect for damage to the shrink-wrap and determine if physical damage has occurred.

Each chiller ships from the factory as a hermetically assembled package; it is factory-assembled, -wired, and -tested. All openings except for the waterbox vent and drain holes are covered or plugged to prevent contamination during shipment and handling. Figure

3, p. 14 shows an illustration of a typical unit and its

components. As soon as the unit arrives at the job site, inspect it thoroughly for damage and material shortages. In addition:

1. Verify the hermetic integrity of the unit by checking the chiller pressure for an indication of holding charge pressure.

2. To prevent damaging moisture from entering the unit and causing corrosion, each chiller is pressurized with 3 to 5 psig (20.7 to 34.5 kPaG) of dry nitrogen before shipment.

To ensure that electrical components operate properly, do NOT locate the chiller in an area exposed to dust, dirt, corrosive fumes, or excessive heat and humidity. The maximum ambient temperature for chiller operation is 104°F (40°C).

Foundation Requirements

Chiller mounting surface must be:

• rigid non-warping mounting pads or a concrete foundation, and

• able to support the chiller at its full operating weight (including completed piping and full operating charges of refrigerant, oil, and water).

For proper unit operation, the chiller must be level within 1/16 in. (1.6 mm) over its length and width when set into place on the mounting surface. “Weights

(lb),” p. 16 and “Weights (kg),” p. 19 show

approximate weights for various chiller sizes and options in pounds and kilograms, respectively.

NNoottee:: For specific weight information, refer to the unit

submittal package.

IImmppoorrttaanntt:: Trane will not assume responsibility for

equipment problems resulting from an improperly designed or constructed foundation.

Rigging

Lifting is the recommended method for moving chillers. Suggested lifting arrangements for standard units are described in “Standard Chiller Lift,” p. 22.

NNoottee:: The lifting beam used for CVHE, CVHF, and

CVHG CenTraVac (4.9 m) long.

If the chiller cannot be moved using a standard chiller lift, consider the following:

• When job site conditions require rigging of the chiller at an angle greater than 45° from horizontal (end-to-end), the unit may require removal of the compressor. Contact Trane or an agent of Trane specifically authorized to perform start-up and warranty of Trane® products regarding the disassembly and reassembly work. For more information, refer to “Factory Warranty

Information,” p. 3.

NNoottee:: Disassembly and reassembly work includes

dowel-pinning the compressor and removing it from the unit. Contact Trane or an agent of Trane specifically authorized to perform startup and warranty of Trane specific rigging instructions. Do NOT attempt to rotate the chiller onto its side.

• When lifting the chiller is either impractical or undesirable, attach cables or chains to the jacking slots shown in Figure 5, p. 23; then push or pull the unit across a smooth surface. Should the chiller be on a shipping skid, it is not necessary to remove the skid from the chiller before moving it into place.

• If removal of the compressor or economizer assembly is necessary to move the chiller to the

products for

operating location, contact Trane. Also refer to

“Factory Warranty Information,” p. 3.

Unit Isolation

To minimize sound and vibration transmission through the building structure and to ensure proper weight distribution over the mounting surface, always install isolation pads or spring isolators under the chiller feet.

NNoottee:: Isolation pads (refer to Figure 6, p. 24) are

provided with each chiller unless spring isolators are specified on the sales order.

Specific isolator loading data is provided in the unit submittal package. If necessary, contact your local Trane sales office for further information.

IImmppoorrttaanntt:: When determining placement of isolation

pads or spring isolators, remember that the control panel side of the unit is always designated as the front side of the unit.

Isolation Pads

When the unit is ready for final placement, position isolation pads (18-in. [457.2-mm] sides) end for end under the full length of the chiller leg. The pads measure 9 in. × 18 in. (228.6 mm x 457.2 mm) and on some units there may be small gaps between pads. Pads are provided to cover entire foot. Place pad flush with the outside edge of the chiller foot and leave excess material under the chiller.

Figure 6. Isolation pad and dimensions

A = 3/8 in. (9.5 mm)

B = 18 in. (457.2 mm)

C = 9 in. (228.6 mm)

Remember that the chiller must be level within 1/16 in. (1.6 mm) over its length and width after it is lowered onto the isolation pads. In addition, all piping connected to the chiller must be properly isolated and supported so that it does not place any stress on the unit.

Spring Isolators

Spring isolators should be considered whenever chiller installation is planned for an upper story location. Base isolator placement is shown in the following figure.

CVHE-SVX02M-EN

IInnssttaallllaattiioonn:: MMeecchhaanniiccaall

Figure 7. Isolation spring placement by shell size, and evaporator and condenser length

Spring isolators typically ship assembled and ready for installation. To install and adjust the isolators properly, follow the provided instructions.

NNoottee:: Do NOT adjust the isolators until the chiller is

piped and charged with refrigerant and water.

IImmppoorrttaanntt:: Do NOT block any serviceable components

such as the lubrication system with fieldinstalled devices such as spring isolators.

1. Position the spring isolators under the chiller as shown in the preceding figure. Ensure that each isolator is centered in relation to the tube sheet.

NNoottee:: Spring isolators shipped with the chiller may

not be identical. Compare the data provided in the unit submittal package to determine proper isolator placement.

2. Set the isolators on the sub-base; shim as necessary to provide a flat, level surface at the same elevation for the end supports.

IImmppoorrttaanntt:: Support the full underside of the

isolator base plate; do NOT straddle gaps or small shims.

3. If required, bolt the isolators to the floor through the slots provided, or cement the pads.

NNoottee:: Fastening the isolators to the floor is not

necessary unless specified.

4. If the chiller must be fastened to the isolators, insert capscrews through the chiller base and into holes drilled and tapped in the upper housing of each isolator.

IImmppoorrttaanntt:: Do NOT allow the screws to protrude

below the underside of the isolator upper housing, or interfere with the adjusting bolts. An alternative method of fastening the chiller to the isolators is to cement the neoprene pads.

5. Set the chiller on the isolators; refer to “Standard

Chiller Lift,” p. 22. The weight of the chiller will

force down the upper housing of each isolator, and could cause it to rest on the isolator’s lower housing (refer to the following figure).

6. Check the clearance on each isolator. If this dimension is less than 1/4 in. (6.35 mm) on any isolator, use a wrench to turn the adjusting bolt one complete revolution upward.

NNoottee:: When the load is applied to the isolators

(refer to Step 5), the top plate of each isolator moves down to compress the springs until either the springs support the load or the top plate rests on the bottom housing of the isolator. If the springs are supporting the load, screwing down on the adjusting bolt (refer to

Step 7) will raise the chiller.

7. Turn the adjusting bolt on each of the remaining isolators to obtain the required minimum clearance of 1/4 in. (6.35 mm).

8. Once the minimum required clearance is obtained on each of the isolators, level the chiller by turning the adjusting bolt on each of the isolators on the low side of the unit. Work from one isolator to the next.

IImmppoorrttaanntt:: The chiller must be level to within 1/

16 in. (1.6 mm) over its length and width, and the clearance of each isolator must be at least 1/4 in. (6.35 mm).

CVHE-SVX02M-EN

IInnssttaallllaattiioonn:: MMeecchhaanniiccaall

Figure 8. Chiller foot and isolator orientation IImmppoorrttaanntt:: Do NOT install spring isolators or brackets

in such a way that they could inhibit chiller servicing such as charging or evacuation, oil tank service, etc.

Leveling the Unit

The chiller must be set level within 1/16 in. (1.6 mm).

1. Measure and make a punch mark an equal distance up from the bottom of each foot of the chiller.

2. Suspend a clear plastic tube along the length of the chiller as shown in the following figure.

3. Fill the tube with water until the level aligns with the punch mark at one end of the chiller.

4. Check the water level at the opposite mark. If the water level does not align with the punch mark, use full length shims to raise one end of the chiller until the water level at each end of the tube aligns with the punch marks at both ends of the chiller.

5. Once the unit is level across its length, repeat the first three steps to level the unit across its width.

Figure 9. Leveling the chiller

NNoottee:: Use of a laser level is an acceptable alternative

method to level the unit.

IImmppoorrttaanntt:: Immediately report any unit damage

incurred during handling or installation at the job site to the Trane sales office.

Installation: Water Piping

Overview

The following water piping circuits must be installed and connected to the chiller:

• Pipe the evaporator into the chilled water circuit.

• Pipe the condenser into the cooling tower water circuit.

• Optional: A heat-recovery condenser water circuit.

• Optional: An auxiliary condenser water circuit.

NNoottee:: Piping must be arranged and supported to avoid

stress on the equipment. It is strongly recommended that the piping contractor does not run pipe closer than 3 ft (0.9 m) minimum to the equipment. This will allow for proper fit upon arrival of the unit at the job site. Any adjustment that is necessary can be made to the piping at that time. Expenses that result from a failure to follow this recommendation will NOT be paid by Trane.

Piping suggestions for each of the water circuits listed above are outlined in “Evaporator and Condenser

Water Piping,” p. 30. General recommendations for the

installation of field-supplied piping components (e.g., valves, flow switches, etc.) common to most chiller water circuits are listed in the following sections.

Water Treatment

The use of untreated or improperly treated water in a CenTraVac™ chiller may result in inefficient operation and possible tube damage.

IImmppoorrttaanntt:: Trane strongly recommends using the

services of a qualified water treatment specialist to determine necessary water treatment. A label with a customer disclaimer note is affixed to each unit.

To determine whether or not pressure relief valves are needed for a specific application, keep in mind that:

a. Vessels with close-coupled shutoff valves may

cause high potentially damaging hydrostatic pressures as fluid temperature rises.

b. Relief valves are required by American Society

of Mechanical Engineers (ASME) codes when the shell waterside is ASME. Follow ASME guidelines or other applicable codes to ensure proper relief valve installation.

Install a strainer in the entering side of each piping circuit to avoid possible tube plugging in the chiller with debris.

Required Flow-Sensing Devices

Use flow paddle switches (refer to “Paddle

Switches,” p. 28), differential pressure switches, or ifm

efector® flow detection controllers and sensors (refer to “Water Flow Detection Controller and Sensor,” p.

28) in conjunction with the pump interlocks to verify

evaporator and condenser water flows.

To ensure adequate chiller flow protection, wire the chiller water and condenser water proof of flow devices per the as-built schematics and submittal, and in accordance with associated notes.

Unless stated otherwise, all flow sensing devices must be field supplied. Be sure to follow the manufacturer’s recommendations for device selection and installation.

Also, review the following general flow switch installation guidelines.

Paddle Switches

Figure 10. Flow paddle switch installation

height of the coupling used to install the switch.

3. Install the flow switch using a coupling that is large enough to allow the insertion of a bushing one pipe diameter larger than the flow switch base as shown in the preceding figure. This will prevent interference with the flow switch paddle.

4. Verify that the direction-of-flow arrow on the switch points in the same direction as actual water flow through the piping circuit.

5. Remove all air from the piping circuit to prevent possible flow switch “fluttering”.

6. Adjust the flow switch to open when water flow is less than normal.

Water Flow Detection Controller and Sensor

IImmppoorrttaanntt:: Before installing the ifm efector®flow

detection controller and sensor, use a marker to draw a line on the probe at 3.5 in. (8.9 cm) from the end of the probe. Do NOT insert more than 3.5 in. (8.9 cm) of the probe length into the pipe. Refer to the following figure.

NNootteess::

• Some type of field-supplied temperature control device may be required to regulate the temperature of the heat-recovery condenser water circuit. For application recommendations, refer to Heat Recovery Seminar (Part 2): Systems/Equipment (AMFND-8).

• Install a bypass valve system to avoid circulating water through the auxiliary shell when the unit is shut down.

• On multiple-pass condensers, entering condenser water must enter at the lowest nozzle.

Piping must be arranged and supported to avoid stress on the equipment. It is strongly recommended that the piping contractor does not run pipe closer than 3 ft (0.9 m) minimum to the equipment. This will allow for proper fit upon arrival of the unit at the job site. Any adjustment that is necessary can be made to the piping at that time. Expenses that result from a failure to follow this recommendation will NOT be paid by Trane.

Water piping connection sizes and components are identified in Table 6, p. 31, Table 7, p. 31, and Table 8,

p. 32. Remember that with many waterboxes, the

entering and leaving evaporator water can be piped to either waterbox connection when the tube bundles are split vertically. However, large evaporator waterboxes with entering and leaving connections not at the same
