NOTICE

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.

Overview

NNoottee:: One copy of this document ships inside the

control panel of each unit and is customer property. It must be retained by the unit’s maintenance personnel.

This manual describes proper installation, operation, and maintenance procedures for air cooled systems. By carefully reviewing the information within this manual and following the instructions, the risk of improper operation and/or component damage will be minimized. It is important that periodic maintenance be performed to help assure trouble free operation. A maintenance schedule is provided at the end of this manual. Should equipment failure occur, contact a qualified service organization with qualified, experienced HVAC technicians to properly diagnose and repair this equipment.

This manual covers installation, operation and maintenance of 20-110 ton Signature Series Commercial Self Contained products with R-410A refrigerant.

R-410A Compressors

• Use crank case heaters which must be energized 24 hours prior to compressor start.

• Contain POE oil which readily absorbs potentially damaging moisture from air.

• Control box includes a phase monitor to detect phase loss, line voltage imbalance and reversal.

Refer to previous IOM versions for R-407C and R-22 units, or contact your local Trane representative.

Refer to the appropriate IOM for air-cooled condenser CXRC-SVX01*-EN and programming IntelliPak™ controls PKG-SVP01*-EN.

Signature Series Self-Contained Unit Components

Commercial self-contained units are complete HVAC systems used in floor-by-floor applications. Units are easy to install because they feature:

• A single point power connection.

• Factory-installed and tested controls.

• A single water point connection.

• Factory-installed options.

• An internally trapped drain connection.

NNoottee:: Refer to the following figure for typical unit

components.

The hermetically sealed scroll compressor motors utilize internal motor protection and time delays to prevent excessive cycling.

Water-cooled units have 2-6 refrigerant circuits and ship with a full refrigerant and oil charge. Each circuit includes filter drier, pressure relief valve, sight glass/ moisture indicator, thermal expansion valve with sensing bulb and external equalizing line, discharge line schrader valve, suction line schrader valve and high and low pressure cutout switches. The watercooled condensers are shell and tube type with an internal subcooler. Condensers are available as mechanically or chemically cleanable.

Air-cooled units have two circuits and ship with oil and a dry nitrogen holding charge. Therefore, air-cooled units require field piping refrigerant connections to an air-cooled condensing unit and charging. Each circuit includes filter drier (field installed), sight glass/ moisture indicator, thermal expansion valve with sensing bulb and external equalizing line, discharge line schrader valve, suction line schrader valve, high and low pressure cutout switches, discharge line check valve and liquid line solenoid valve.

All units include liquid line service valves for each circuit as standard (suction and discharge service valves are optional).

Evaporator fans are double width, double inlet and forward curved with fixed pitch belt drive assembly. Variable frequency drives are optional. EISA efficiency open drip proof (ODP) and totally enclosed fan cooled (TEFC) motor options are available.

Standard Controls

Standard controls supplied with the unit include the human interface (HI) panel with unit control module (UCM). All basic setup parameters are preset from the factory.

Human Interface Panel

The HI is unit mounted and accessible without opening the unit’s front panel. It allows easy setpoint adjustment using the HI keypad. In addition, the HI displays all unit operating parameters and conditions in a clear language display, which can be configured for either English, French, or Spanish.

The optional remote human interface (RHI) will control up to four self-contained units, each containing an interprocessor communications bridge (IPCB). It has all the same features as the unit-mounted HI except for the service mode.

For more information on setpoint defaults and ranges and unit programming, see the Self-Contained Programming Guide, PKG-SVP01*-EN. A copy ships with each unit.

Unit Control Module

The UCM provides “smart” unit control with safety features and control relays for pumps, dampers, etc.

SCXF-SVX01Q-EN

The Signature Series self-contained unit is controlled by a microelectronic control system that consists of a network of modules. Modular Series self-contained unit is controlled by microelectronic control system consisting of a network of modules.These modules are referred to as unit control modules (UCM). In this manual, the acronym UCM refers to the entire control system network.

These modules perform specific unit functions using proportional/integral control algorithms. They are mounted in the unit control panel and are factory wired to their respective internal components. Each module receives and interprets information from other unit modules, sensors, remote panels, and customer binary contacts to satisfy the applicable request; i.e., economizing, mechanical cooling, heating, ventilation.

See the Owner’s section of this manual for a detailed description of each module’s function.

OOvveerrvviieeww

Figure 2. Right side view of unit Optional Controls

Optional controls include a disconnect switch, dirty filter switch, water flow switch (water-cooled only), supply air temperature reset, or external setpoint inputs. Daytime heating is available on units with electric, steam, or hot water heat control options. Morning warm-up operation is available on all units.

The static pressure probe, zone night heat/morning warm-up, supply air temperature reset sensor options ship separate inside the unit control panel for field installation. For more detailed information on the unit control options, see the Owner’s section of this manual.

Unit Nameplate

The unit nameplate identifies the unit model number, appropriate service literature, and wiring diagram numbers. It is mounted on the left end of the unit control panel.

Pre-Installation

Receiving

Receiving Checklist

Complete the following checklist immediately after receiving unit shipment to detect possible shipping damage:

• Inspect individual cartons before accepting. Check for rattles, bent carton corners, or other visible indications of shipping damage.

• If a unit appears damaged, inspect it immediately before accepting the shipment. Make specific notations concerning the damage on the freight bill. Do not refuse delivery.

• Inspect the unit for concealed damage before it is stored and as soon as possible after delivery. Report concealed damage to the freight line within the allotted time after delivery. Check with the carrier for their allotted time to submit a claim.

• Do not move damaged material from the receiving location. It is the receiver’s responsibility to provide reasonable evidence that concealed damage did not occur after delivery.

• Do not continue unpacking the shipment if it appears damaged. Retain all internal packing, cartons, and crate. Take photos of damaged material if possible.

• Notify the carrier of the damage immediately by phone and mail. Request an immediate joint inspection of the damage by the carrier and consignee.

NNoottee:: Notify your Trane representative of the damage

and arrange for repair. Have the carrier inspect the damage before making any repairs to the unit.

Ship-Separate Accessories

Field-installed sensors ship separately inside main control panel of the unit. Extra filters, sheaves, and belts ship in the fan motor section of the unit. Condenser plugs, spring isolators, and Iso-pads ship stored in the bottom left side of the unit.

Contractor Installation Responsibilities

Complete the following checklist before beginning final unit installation:

• Verify the unit size and tagging with the unit nameplate.

• Make certain the floor or foundation is level, solid, and sufficient to support the unit and accessory weights. Level or repair the floor before positioning the unit if necessary.

• Allow minimum recommended clearances for routine maintenance and service. Allow space at

end of the unit for shaft removal and servicing. Refer to the unit submittals for dimensions. See also the “Service Clearances” section in the Dimensional Data chapter.

• Allow three fan diameters above the unit for the discharge ductwork. Return air enters the rear of the unit and conditioned supply air discharges through the top.

• Electrical connection knockouts are on the top, left side of the unit.

• Allow adequate space for piping access and panel removal. Condenser water piping, refrigerant piping, and condensate drain connections are on the lower left end panel.

NNoottee:: Unit height and connection locations will

change if using vibration isolators. The unit height may increase up to 5-7/8” with spring type isolators.

• Electrical supply power must meet specific balance and voltage requirements as described in chapter “Electrical Installation”.

• Water-cooled units only: The installer is responsible for providing a condenser main, standby water pump, cooling tower, pressure gauges, strainers, and all components for waterside piping. See

“Water Piping,” p. 38 for general waterside

recommendations.

• Air-cooled units only: The installer is responsible for providing and installing the remote air-cooled condenser and refrigerant piping.

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.

• Verify that the power supply complies with the unit nameplate specifications.

SCXF-SVX01Q-EN

Shipping Cover

PPrree--IInnssttaallllaattiioonn

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.

Figure 3. Typical unit shipping package

• 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.

Unpacking

Commercial self-contained units ship assembled with protective coverings over the coil and discharge openings.Figure 3, p. 22 illustrates a typical shipping package.

SCXF-SVX01Q-EN

PPrree--IInnssttaallllaattiioonn

Unit Protective Covers

Remove shipping protection coverings from human interface panel (HI) at control panel, filter box (or air inlet opening), discharge air opening, and optional variable frequency drive (VFD).

Supply Fan Isolators

Remove the shipping channels and four fan mounting bolts from beneath the fan. Open both fan compartment doors to access the channels.

Figure 4. Fan Assembly Shipping Spacer Locations
