SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air- conditioning equipment can be hazardous and requires specific  knowledge  and training. Improperly installed, adjusted or altered equipment by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that are attached to the equipment.

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.
CAUTION 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.
WARNING
Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards.  To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes.
WARNING
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the instructions below:

• Before installing/servicing this unit, technicians MUST put on all PPE required for the work being undertaken (Examples; cut resistant gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall protection, electrical PPE and arc flash clothing). ALWAYS refer to appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals, ALWAYS refer to the appropriate SDS and OSHA/GHS (Global Harmonized System of Classification and Labeling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection and handling instructions.
• If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash protection, PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED FOR INTENDED VOLTAGE.

WARNING
Follow EHS Policies!
Failure to follow instructions below could result in death or serious injury.

• All Trane personnel must follow the company’s Environmental, Health and Safety (EHS) policies when performing work such as hot work, electrical, fall protection, lockout/tagout, refrigerant handling, etc. Where local regulations  are more stringent than these policies, those regulations supersede these policies.
• Non-Trane personnel should always follow local regulations.

General Information

These rental air handling units are custom Trane air handlers modified for use as rental units. The majority of the modifications are related to framing for rigging purposes, connection of chilled water piping, and temporary duct connection.
RSAU0010F0 – F1
Units contain hydronic water coils that can be utilized for cooling or hot water applications, but the coils cannot be used with steam because they will be damaged. Each model has been selected for use with 100% outside air without return air duct connections.
The air handlers have unit mounted variable frequency drives (VFDs) with a potentiometer to adjust airflow (CFM) settings on the drive located inside each unit’s control panel.
RSAU0010F2
Units have chilled water-cooling coils which can be used for hot water and not for steam applications. Each unit has input/ output 16 series cam type power cable receptacles to allow daisy-chaining supply voltage conductors to other air  handler models of the same type in series.
The air handlers have unit mounted variable frequency drives (VFDs) with bypass to allow the fan to run at full speed in an event the VFD is damaged. A potentiometer is utilized to adjust airflow (CFM) settings locally on the drive located inside each unit’s control panel.
RSAU0025F1, RSAU0050F1, and RSAU0062F1
Units contain both chilled water and hot water coils for year-round operation. Each unit has been selected for use with 100% outside air, but include return plenums and dampers to allow for 100% return air.
A Trane TR2 variable frequency drive (VFD) is included to control the fan motor. The VFD is controlled with a potentiometer dial. For additional information on the unit controls see “Controls Information,” p. 43.
RSAU0025F2, RSAU0050F2, and RSAU0062F2
Each unit contains a single water coil that can be used for hot water or chilled water operation. Each unit has been selected for use with 100% outside air. Return connections and dampers allow for 100% return air.
Two Trane TR200 variable frequency drives (VFD) are included to control the dual plenum fans. Both VFDs receive input from a single potentiometer dial for fan speed. For additional information on the unit controls, see “Controls Information,” p. 43.
RSCC0030F0
Units contain hydronic chilled water-cooling coils with 4-inch Victaulic manifolds that must be installed in the field outside each unit cabinet. Each unit model has been selected for use with 100% outside air with four discharge air ducts  and six return air duct connections. Two units are capable of being stacked at a time. All units have input/out 16 series cam type power cable receptacles to allow daisy-chaining supply voltage conductors to other air handler models of the  same type in series.
Air handlers have four, unit mounted TR150 variable frequency drives (VFDs) with bypass to allow the fan(s) to run at full speed in an event the VFD is damaged. Each supply fan airflow (CFM) can be adjusted utilizing the VFD speed potentiometer dial mounted on the outside of the top control panel located on the width side of each AHU.
Order of AHU Sections in Direction of Airflow
The figures below illustrate the general construction of all Trane Rental Air Handling Units.

Application Considerations – Air Handler Units

Freeze Protection
In ambient temperatures 32°F (0°C) and below freezing, it is recommended that a non-freezing, low temperature, corrosion inhibiting, heat transfer fluid be added to the chilled water system. The solution must be strong enough to provide protection against ice formation at the lowest anticipated fluid temperature. As a result of low fluid temperature below 40°F (4°C), glycol or other antifreeze solution may be utilized for hydronic systems. Contact Trane Rental  Services engineering for more information on glycol percentage recommendations.
In addition to using glycol, it is highly recommended that all exposed pipe external to equipment enclosures be heat traced and insulated. Follow the recommended guidelines by the heat tracing manufacturer.
NOTICE
Coil Freeze-Up!
Failure to follow instruction below could result in equipment damage.
Drain and vent coils when not in use. Trane recommends glycol protection in all possible freezing applications. Use a glycol approved for use with commercial cooling and heating systems and copper tube coils.

Rigging Guidelines

General Lifting Considerations

WARNING
Risk of Unit Dropping!
Failure to follow instructions below could result in death or serious injury, and equipment damage. Inspect the suspension and/or support system to ensure all fasteners are tight and the unit is secure before working underneath the unit.
WARNING
Improper Unit Lift!
Failure to properly lift unit could result in unit dropping and possibly crushing operator/technician which could result in death or serious injury, and equipment or property-only damage.
Test lift unit approximately 24 inches (61 cm) to verify proper center of gravity lift point. To avoid dropping of unit, reposition lifting point if unit is not level.
WARNING
Heavy Objects!
Failure to properly lift unit could result in death or serious injury or possible equipment or property-only damage.
Use a forklift/crane of suitable capacity to move the unit.
NOTICE
Equipment Damage!
Premature skid removal could result in equipment damage.
Keep skid in place until unit is ready to set. Do not move the unit or subassembly without the skid in place as shipped from the factory.
Each AHU has forklift pockets and either an overhead lifting frame or base mounted lifting lugs (Figure 53). Before unit lifting, refer to pages 9-31 for unit dimensions and weights.
Test the unit for proper balance before lifting.

• Lift sections using all lifting lugs or fork pockets provided.
• When hoisting the unit into position, use the proper rigging method, such as straps, slings, spreader bars, or lifting lugs for protection and safety.
• Make the loop of the sling parallel to the direction of airflow whenever possible.
• Each cable used to lift the unit must be capable of supporting the entire weight of the unit.
• Never lift units in windy conditions. Personnel should be positioned overhead and, on the ground, to guide the crane operator in positioning the sections.

In addition to the start-up guidelines below, refer to start-up information in the Climate Changer Custom Air Handlers Installation, Operation, and Maintenance Manual CLCHSVX010-EN for RSAU0025, 50 and 62 Series AHUs and CLCH-SVX07-EN for RSCC0030 Series AHUs.

WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.
Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/ tagout procedures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided by Trane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for discharge of capacitors. Verify with a CAT III or IV voltmeter rated per
NFPA 70E that all capacitors have discharged.
Installation

1. Install piping manifold supplied with unit (if applicable) and ensure all temporary piping is properly secured. See “Piping Connection Configuration,” p. 37.

2. Install the p-trap supplied with unit. The unit p-trap is located inside the machine in a bin mounted to the filter access door.
   Notes:
   • RSAU0010F0-F1 utilize condensate pumps and do not have p-traps.
   • RSAU0010F2 has built-in p-traps and do not need the p-trap field installed.
   • RSAU0010F2 units can utilize gravity feed p-trap or built-in condensate pump.
   Determine whether condensate pump will be used and connect condensate drain piping accordingly.

3. Close all coil drains and open the valves and fill the system with fluid, checking for leaks. Bleed all air out of water system using field installed vales at high points in the system.

4. Install temporary supply ductwork and open manual dampers (if equipped).

5. For AHUs with return duct connections, install temporary return air ductwork.
