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.
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 Labelling 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.

Required Tools

Qty	Description
1	4 mm hex wrench (provided)
1	Drill
1	4 mm (5/32-in.) drill bit
1	3 mm hex wrench (provided)
1	Phillips screwdriver
1	Small flat-blade screwdriver

Mounting Position

Installation

Note: Actuator is shipped with 5° preload. When power is applied to the actuator, the preload is released. To manually release the preload, insert the 3 mm hex key in the override opening and turn the key in the direction of the arrow. See “Manual Override,” p. 8.
The expected installation time is 30 minutes. Important:

• Do not open actuator.
• Do not turn the 3 mm hex key against the direction of the arrow.

See Figure 3, p. 7 for step 1 through 3.

1. Adjust the shaft length for mounting the actuator.
2. Align the self-centering shaft adapter to the alignment mark on the actuator and insert the shaft adapter into the mounting hole on the adapter.
   Note: Confirm that the shaft adapter is placed next to the alignment mark, keeping the mark visible.
3. Using the locking clip, lock the shaft adapter in place.

Figure 3. Shaft length and shaft adapter mounting location

Close the damper. See Figure 4, p. 8.Note: If the damper fail-safe position is open, change the actuator preload from the preset 5° to 85°.
See “Manual Override,” p. 8 . Mount the actuator onto the shaft. See Figure 5, p. 8.
Using 4 mm (5/32-in.) drill bit, drill two holes one at each end of the mounting bracket. See Figure 6, p. 8.
Attach the mounting bracket and fasten using two mounting screws. See Figure 6, p. 8.Using the 4 mm hex wrench, fasten the shaft adapter to the damper shaft. See Figure 7, p. 8.

Manual Override

To manually override or set preload:

1. Insert the 3 mm hex key in the override opening.
2. Turn the key in the direction of the arrow until it reaches the desired degree of opening.
3.  Hold the key in place.
4. Insert a small flat-blade screwdriver into the gear train lock pin. Turn the screwdriver in the same direction as the arrow until it clicks or meets slight resistance (approximately 5 degrees rotation).

NOTICE
Manual Override
To manually override or set preload:

1. Insert the 3 mm hex key in the override opening.
2. Turn the key in the direction of the arrow until it reaches the desired degree of opening.
3. Hold the key in place.
4. Insert a small flat-blade screwdriver into the gear train lock pin. Turn the screwdriver in the same direction as the arrow until it clicks or meets slight resistance (approximately 5 degrees rotation).

Wiring

• All wiring must conform to NEC and local codes and regulations.
• Use earth ground isolating step-down Class 2 transformers. Do not use autotransformers.

Note: The maximum rating for a Class 2 stepdown transformer is 100 VA. Determine the supply transformer rating by summing the VA ratings of all actuators and all other components used. It is recommended that not more than 80% of the transformer VA be utilized. The 62 lb-in actuator consumes 8 VA or less.
Either AC line voltage from the same phase must be applied to all six outputs of the dual auxiliary switches, or UL-Class 2 voltage must be applied to all six outputs.
Note: With Plenum cables, only UL-Class 2 voltage is permitted.
