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:

WARNING

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

CAU

TION

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.

NOTICE

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.

General Information

Unit Description

The Ascend™ ACR units are helical-rotary type, aircooled chillers designed for outdoor installation. The refrigerant circuits are factory-piped, leak tested and dehydrated. Every unit is electrically tested for proper control operation before shipment.

Chilled water inlet and outlet openings are covered for shipment. The chiller features Trane’s exclusive Adaptive Control™ logic, which monitors the control variables that govern the operation of the chiller unit. Adaptive Control logic can adjust capacity variables to avoid chiller shutdown when necessary, and keep producing chilled water. The units feature two independent refrigerant circuits. Each circuit utilizes at least one compressor driven by an Adaptive Frequency Drive. Each refrigerant circuit is provided with filter, sight glass, electronic expansion valve, and charging valves. The shell-and-tube evaporator is manufactured in accordance with the ASME standards or other international codes. Each evaporator is fully insulated and equipped with water drain and vent connections.

Units are shipped with full oil charge and can be ordered with either a factory refrigerant charge, or optional nitrogen charge.

Unit Length

Units are EXTENDED length if either of the following are selected:

• Transformer: Model number digit 28 = 1

• Harmonic Filtration Option: Model number digit 29 = 1

Units without Harmonic Filtration Option or Transformer (digits 28, 29 = 0X) are STANDARD length.

Accessory/Option Information

Check all the accessories and loose parts which are shipped with the unit against the shipping list. Included in these items will be water vessel drain plugs, electrical diagrams, and service literature, which are placed inside the control panel for shipment.

If optional elastomeric isolators are ordered with unit (model number digit 36 = 1), they are shipped mounted

on diagonal supports on the end of the unit opposite control panel. See figures below.

Pre-Installation

Unit Inspection

To protect against loss due to damage incurred in transit, perform inspection immediately upon receipt of the unit.

Exterior Inspection

If the job site inspection reveals damage or material shortages, file a claim with the carrier immediately. Specify the type and extent of the damage on the bill of lading before signing. Notify the appropriate sales representative.

IImmppoorrttaanntt:: Do not proceed with installation of a

damaged unit without sales representative’s approval.

• Visually inspect the complete exterior for signs of shipping damages to unit or packing material.

• Verify that the nameplate data matches the sales order and bill of lading.

• Verify that the unit is properly equipped and there are no material shortages.

NNoottee:: Corrosion due to dirt, road grim, road salt, and

other contaminates picked up during shipping is not the responsibility of the carrier.

Inspection for Concealed Damage

Visually inspect the components for concealed damage as soon as possible after delivery and before it is stored.

If concealed damage is discovered:

• Notify the carrier’s terminal of the damage immediately by phone and by mail.

• Concealed damage must be reported within 15 days.

• Request an immediate, joint inspection of the damage with the carrier and consignee.

• Stop unpacking the unit.

• Do not remove damaged material from receiving location.

• Take photos of the damage, if possible.

• The owner must provide reasonable evidence that the damage did not occur after delivery.

Repair

Notify the appropriate sales representative before arranging unit installation or repair.

IImmppoorrttaanntt:: Do not repair unit until the damage has

been inspected by the carrier’s representative.

Storage Requirements

Extended storage of outdoor unit prior to installation requires these precautionary measures:

• Store the outdoor unit in a secure area.

• For units that have been charged with refrigerant, verify the following valves are closed on each circuit:

– Suction service valve (butterfly valve)

– Liquid line angle valve or EXV (EXV is driven

closed whenever circuit is powered)

– Oil line shutoff valves to brazed plate heat

exchangers

NNoottee:: Units with factory refrigerant charge (model

number digit 15 = 1) are shipped with suction, liquid and oil line shutoff valves closed, isolating most of refrigerant charge in the evaporator. If unit goes directly into long term storage, it is recommended that these valve positions be confirmed.

• For units with nitrogen charge option (model number digit 15 = 2), units are shipped with valves open. If unit goes directly into storage prior to refrigerant charge, confirm all service valves are open.

• At least every three months (quarterly), check the pressure in the refrigerant circuits to verify that the refrigerant charge is intact. If it is not, contact a qualified service organization and the appropriate Trane sales office.

Installation Mechanical

Location Requirements

Sound Considerations

• Locate the unit away from sound-sensitive areas.

• Install the optional elastomeric isolators under the unit. See Isolation and Sound Emission section.

• Chilled water piping should not be supported by chiller frame.

• Install rubber vibration isolators in all water piping.

• Use flexible electrical conduit.

• Seal all wall penetrations.

NNoottee:: Consult an acoustical engineer for critical

applications.

Foundation

Provide rigid, non-warping mounting pads or a concrete foundation of sufficient strength and mass to support the applicable operating weight (i.e., including completed piping, and full operating charges of refrigerant, oil and water). See Dimensions and Weights chapter for unit operating weights. Once in place, the unit must be level within 1/4” (6.4 mm) across the length and width of the unit. The Trane Company is not responsible for equipment problems resulting from an improperly designed or constructed foundation.

Clearances

Provide enough space around the unit to allow the installation and maintenance personnel unrestricted access to all service points. See submittal drawings for the unit dimensions, to provide sufficient clearance for the opening of control panel doors and unit service. See Dimensions and Weights chapter for minimum clearances. In all cases, local codes which require additional clearances will take precedence over these recommendations.

For close spacing information, see RLC-PRB037*-EN.

Isolation and Sound Emission

The most effective form of isolation is to locate the unit away from any sound sensitive area. Structurally transmitted sound can be reduced by elastomeric vibration eliminators. Spring isolators are not recommended. Consult an acoustical engineer in critical sound applications.

For maximum isolation effect, isolate water lines and electrical conduit. Wall sleeves and rubber isolated piping hangers can be used to reduce the sound transmitted through water piping. To reduce the sound transmitted through electrical conduit, use flexible electrical conduit.

State and local codes on sound emissions should always be considered. Since the environment in which a sound source is located affects sound pressure, unit placement must be carefully evaluated. Sound power levels for Stealth chillers are available on request.

Unit Isolation and Leveling

For additional reduction of sound and vibration, install the optional elastomeric isolators.

Construct an isolated concrete pad for the unit or provide concrete footings at the unit mounting points.

Mount the unit directly to the concrete pads or footings.

Level the unit using the base rail as a reference. The unit must be level within 1/4” (6.4 mm) over the entire length and width. Use shims as necessary to level the unit.

Elastomeric Isolators

NNoottee:: See unit submittal, or tables in this section, for

point weights, isolator locations and isolator selections.

1. Secure the isolators to the mounting surface using the mounting slots in the isolator base plate. Do not fully tighten the isolator mounting bolts at this time.

2. Align the mounting holes in the base of the unit with the threaded positioning pins on the top of the isolators.

3. Lower the unit onto the isolators and secure the isolator to the unit with a nut.

4. Level the unit carefully. Fully tighten the isolator mounting bolts.
