Installation Information
Modular 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, single water point connection, factory installed options, and an internally trapped drain connection. Modular self-contained units can ship as split-apart units for installation ease. Splitapart units ship with a dry nitrogen charge and require field refrigerant charging.
Units consist of multiple compressors, water-cooled condensers (water-cooled units only), an evaporator coil, dual forward curved fans, and control panel. Air-cooled units require a remote aircooled condenser, model CXRC.The hermetically sealed 3-D scroll compressor motors utilize internal motor protection and time delays to prevent excessive cycling. Unit controls are either an electromechanical thermostat or microprocessor controls on the IntelliPak unit. See Figure I-GI-1 for a typical unit.
The hermetically sealed 3-D scroll compressor motors utilize internal motor protection and time delays to prevent excessive cycling.
The water-cooled condensers are shell and tube type with an internal subcooler. Condensers are available as mechani-
cally or chemically cleanable.The evaporator fan is double width, double inlet and forward curved with a fixed pitch belt drive assembly. Frequency drives or inlet guide vanes are optional. Motor options are standard efficiency open drip proof (ODP) or totally enclosed fan cooled (TEFC); or premium efficiency ODP.
All water-cooled units ship with a full refrigerant and oil charge. Air-cooled units ship with oil and a dry nitrogen holding charge and require field-piping refrigerant connections to the air cooled
condensing unit. Also, air-cooled units have two refrigerant circuits. Watercooled units have four refrigerant circuits; which include a filter drier, pressure relief valve, liquid line service valve, sight glass/ moisture indicator, thermal expansion valve with a sensing bulb and external equalizing line, discharge line shrader valve, a suction line shrader valve, and high and low pressure cutout switches. Water-cooled units also include a liquid line service valve for each circuit.
For more detailed information, see the Owner’s section of this manual.

General
Installation Information
Control Options
Units can have either a thermostat control or IntelliPak® UCM control network.
IntelliPak® Unit Controls
Standard controls supplied with the IntelliPak® unit include the human interface (HI) panel with unit control module (UCM), hi/lo inlet air temperature sensor, and frost protection. All 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 IntelliPak® Self-Contained Programming Guide, PKG-SVP01B-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. The Modular Series IntelliPak® self-contained unit is controlled by a microelectronic control system that consists 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.
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. Night heat/morning warmup is available with electric, steam, or hot water heat control options.
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.

Installation Considerations
Receiving and Handling
Shipping Package
Commercial self-contained units ship assembled on skids with protective coverings over the coil and discharge openings. Figure I-PC-1 illustrates a typical shipping package.
Ship-Separate Accessories
Field-installed sensors ship separately inside the unit’s main control panel. Extra filters, sheaves, and belts ship in the unit’s fan motor section. Condenser plugs, spring isolators, and isopads ship in the unit’s bottom left side.
Receiving Checklist
Complete the following checklist immediately after receiving unit shipment to detect possible shipping damage.
οInspect individual cartons before accepting. Check for rattles, bent carton corners, or other visible indications of shipping damage.
οIf 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.
οInspect 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.
οDo 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.
οDo not continue unpacking the shipment if it appears damaged. Retain all internal packing, cartons, and crate. Take photos of damaged material if possible.
οNotify the carrier’s terminal of the damage immediately by phone and mail. Request an immediate joint inspection of the damage by the carrier and consignee.
οNotify yourTrane representative of the damage and arrange for repair. Have the carrier inspect the damage before making any repairs to the unit.

Pre-Installation
Installation Considerations
Installation Preparation
Before installing the unit, perform the following procedures to ensure proper unit operation.
1.Verify the floor or foundation is level. Shim or repair as necessary.To ensure proper unit operation, install the unit level (zero tolerance) in both horizontal axis. Failure to level the unit properly can result in condensate management problems, such as standing water inside the unit. Standing water and wet surfaces inside units can result in microbial growth (mold) in the drain pan that may cause unpleasant odors and serious health-related indoor air quality problem.
2.Allow minimum recommended clearances for maintenance and routine service. See “Service Access” section on page 11.
3.Position the unit and skid assembly in its final location. If unit shipped splitapart, follow the procedure in the “Split-Apart Unit Assembly” section on page 14 before completing this step.Test lift the unit to determine exact unit balance and stability before hoisting it to the installation location. See Figure I-PC-7 and I-PC-8 on page 13 for typical rigging procedures, including cautions and proper uses of such equipment as fork lifts, spreader bars, and hooks.
4.Remove the skids from under the unit. See the “Rigging and Handling” section on page 12. Refer to the “Skid Removal” section on page 16. If you find internal damage, file a claim immediately to the delivering carrier.
5. Remove the protective shipping covers from the unit. Refer to the “Unit Protective Covers” section on page 39.
Note: Unit height and connection locations will change if external vibration isolators are used. The unit may be raised an additional 5 7/8 inches with spring-type isolators.

Rigging and Unit Handling
Before lifting the unit or modular component, determine the approximate center of gravity for lifting safety. See Figure I-PC-5 for assembled modular units and Figure I -PC-6 for split-apart units. The center of gravity may vary slightly within the gravity block depending on unit options.
! WARNING
Ensure lifting equipment capacity exceeds unit weight by an adequate safety factor to prevent injury, death, or unit damage.
Always test-lift the unit to determine the exact unit balance and stability before hoisting it to the installation location. See Figures I-PC-7 and I-PC-8 for typical rigging procedures and proper rigging equipment usage.
! WARNING
To prevent injury or death and unit damage, always test-lift the unit to determine actual center of gravity. See Figures I-PC-5 and I- PC-6.

Pre-Installation
Installation Considerations
Skid Removal
The unit ships on skids to provide forklift locations from the front or rear.The skid allows easy maneuverability of the unit during storage and transportation.
Remove the skids before placing the unit in its permanent location.
Remove the skids using a forklift or jack. Lift one end of the unit off of the skids. See Figure I-PC-5 and I-PC-6 on page 12 for unit gravity block location. Slide the skids out and lower the unit at the installation location.
Note: External isolation is not necessary since units are internally isolated. Consult a vibration specialist before “doubleisolating” the unit.
External Unit Isolation
If your job requires external vibration isolation, two options are available: isopads or spring-type isolators. Isopads should be placed under the unit at locations indicated on the factoryprovided isolator sheet.
Set the spring-type isolators (Figure I-PC- 9) in position after the unit is removed from skids before making electrical, piping, or duct connections. All units require a minimum of four isolators per unit. But some may require six isolators, depending upon unit options. Note: The Trane Company strongly recommends you consult a vibration specialist before double-isolating the unit. Double isolation is not recommended.
If you decide to externally isolate the unit, use spring-flex, type CP isolators. The spring number is marked on the outer housing. See Figure I-PC-9.
To install external isolators, complete the following procedure.
1.Locate the isolators under unit base at the locations indicated on the factoryprovided isolator placement sheet. Lift one end of the unit at a time to position isolators to the floor, using anchor bolts.
2.Level the unit by adjusting isolator heights. Unit weight may cause the upper housing to rest on the lower housing of the spring isolators. The isolator clearance shown in the side view of Figure I-PC-9, must be 1/4 - 1/2 inches.To increase the clearance, lift
Figure I-PC-9. Optional spring isolator dimensional data.
the unit off the isolator and turn the leveling bolt counterclockwise. Recheck the unit level and the housing clearances. Maximum allowable difference between isolator heights is 1/4 inch. Shim as required under the isolators.
Note: The compressors and fan assembly are internally isolated on most units. Due to this, the addition of external isolation devices (spring mounting isolators) is at the discretion of the building or HVAC system designer.
Pre-Installation Checklist
Complete the following checklist before beginning unit installation.
οVerify the unit size and tagging with the unit nameplate.
οMake certain the floor or foundation is level, solid, and sufficient to support the unit and accessory weights. SeeTable I-DW-1 on page 32. Level or repair the floor before positioning the unit if necessary.
οAllow minimum recommended clearances for routine maintenance and service. Refer to unit submittals for dimensions.
οAllow 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.
οElectrical connection knockouts are on the top, left side of the unit.
οAllow adequate space for piping access and panel removal. Condenser water piping, refrigerant piping, and condensate drain connections are on the lower left end panel.
Note: 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.
οElectrical supply power must meet specific balance and voltage requirements as described in the “Electrical Requirements” section on page 37.
οWater-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 the “Water Piping” section on page 34 for general waterside recommendations.
οAir-cooled units only: The installer is responsible for providing and installing the remote air-cooled condenser and refrigerant piping, including filter driers.
