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 CenTraVacchiller 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.
For the USA, 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. This access valve is located on the front of the oil tank, which is at the right rear corner of the chiller. 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 21 gallons (79.5 L) of oil. The oil level should be visible to about halfway in the top sight glass. 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 5. 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.“Unit
Components,” p. 16 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.

General Information

Regulations regarding waste handling are constantly changing. To ensure that personnel are in compliance with the latest local, state, and federal regulations, contact your local waste management office for the proper procedures on handling, disposal, transporting,

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 ambient temperature range for chiller operation is 34°F to 104°F (1.1°C to 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. 18 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 CenTraVac
must be at least 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. 4.
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 the figure in “Standard Chiller
Lift,” p. 22; 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

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 the figure in “Isolation
Pads,” 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.
Figure 9. 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; also refer to the following table.

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.
CVHH-SVX001G-EN
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, screw 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.

Note: The spring isolator must be centered in relation to the tube sheet. Do not align the isolator with the flat part of the chiller foot since the tube sheet is often off center.
Note: The length of the isolator should be parallel to the leg.
IInnssttaallllaattiioonn:: MMeecchhaanniiccaall
4. If the chiller must be fastened to the isolators, insert cap screws 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 screws. 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 screw 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 screw (refer to Step 7) will raise the chiller.
7. Turn the adjusting screw 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 screw 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).
Figure 11. 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.

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 CenTraVacchiller 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.

Pressure Gauges

Locate pressure gauge taps in a straight length of pipe. Place each tap a minimum of one pipe diameter downstream of any elbow, orifice, etc. For example, for
a 6 in. (16 cm) pipe, the tap would be at least 6 in. (16 cm) from any elbow, orifice, etc.

2. If necessary for the application, install pressure­relief valves at the drain connections on the evaporator and condenser waterboxes. To do so, add a tee with the relief valve attached to the drain valve. Follow local codes for determining if drain connection is large enough for relief devices.
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 waterside is ASME. Follow ASME guidelines or other applicable codes/local regulation to ensure proper relief valve installation.

Required Flow-Sensing Devices

The ifm efector® flow detection controller and sensor (refer to “Water Flow Detection Controller and Sensor
—ifm efector,” p. 29) is used to verify evaporator and
condenser water flows.
If a customer-supplied flow sensing device is used to ensure adequate chiller flow protection, refer to the wiring diagrams that shipped with the unit for specific electrical connections.
Be sure to follow the manufacturer’s recommendations for device selection and installation.

Water Flow Detection Controller and Sensor—ifm efector

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.
Figure 13. Installation of ifm efector®® flow detection controller and sensor
1. Mount the 1/2-in. NPT adapter in a horizontal or vertical section of pipe. The maximum distance
CVHH-SVX001G-EN
from the control panel must not exceed 29.5 ft (9 m) (see item labeled “1” in the preceding figure). Allow at least five pipe diameters straight run of pipe upstream of the sensor location, and three pipe diameters straight run of pipe downstream of the sensor location.
NNoottee:: In the case of a horizontal pipe, mounting the
sensor in the side of the pipe is preferred. In the case of a vertical pipe, mounting the sensor in a place where the water flows upwards is preferred.

Before servicing, disconnect all power sources and allow at least 30 minutes for capacitors to discharge.
All electrical enclosures—unit or remote—are IP2X.
5. Apply power to the chiller control panel to verify the Flow Control Monitor has power and the Low Volt Broken Wire Relay light is NOT lit.
6. Remove all air from the piping circuit prior to adjusting the low water flow setpoint.
7. Reduce the water flow to the minimum allowable flow and adjust the Flow setting on the Flow Control Monitor (see item labeled “7” in the following figure). Adjusting the “Flow” potentiometer clockwise (+) reduces the flow setting cutout and adjusting counterclockwise (-) increases the flow setting cutout.
NNoottee:: The “Temp” potentiometer on the ifm
efector
®
control module has no effect in Trane application. It is NOT necessary to make adjustments to the “Temp” potentiometer.
8. After the cutout setting is adjusted, the cutout setpoint will be indicated with a yellow light on the Flow Control Monitor LED bar graph display. When the water flows are higher than the cutout, a green light will indicate proper flow status. If the flows fall below the cutout setpoint, a red light will indicate
low/no flow status.

Evaporator and condenser proof of flow switches are required. These switches are used with control logic to confirm flow prior to starting a unit and to stop a running unit if flow is lost. For troubleshooting, a viewable diagnostic is generated if a proof of flow switch does not close when flow is required.
