Installation Instructions

Safety Warnings, Cautions, and Notices

Read this manual thoroughly before operating or servicing this unit. 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.
• ℹ️ 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, 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 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 and follow applicable laws.

Installation Precautions

• ⚠️ 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. 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 MUST follow precautions in this manual and on tags, stickers, and labels, as well as the instructions below:
  • Before installing/servicing, technicians MUST put on all PPE required for the work (e.g., cut resistant gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall protection, electrical PPE, 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 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. 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.

Inspection

1. Inspect the shipping carton and its contents. Check for concealed damage before it is stored or used. If any damage is found, report it immediately, and file a claim against the transportation company. Replace damaged parts with authorized parts only.
2. Compare the order number on the shipping label with the accessory identification information on the ordering and shipping documents to verify that the correct accessory has been received.

Installation

⚠️ 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. Verify with a CAT III or IV voltmeter rated per NFPA 70E that all capacitors have discharged.

1. Open and lock unit disconnect.
2. Detach pipe, p-trap connected to condensate drain opening in the post.
3. Remove indoor refrigeration coil panel (A), indoor fan panel (B), heat section panel(s) (C), followed by the vertical post (D) to which these were attached. See Figure 1.

   Figure 1: Diagram showing removal of indoor refrigeration coil panel (A), indoor fan panel (B), heat section panel(s) (C), and vertical post (D).

4. Locate drain pan below the evaporator coil. The hole is on the front end cap of the drain pan. See Figure 2.

   Figure 2: Diagram illustrating the location of the drain pan below the evaporator coil, highlighting the hole on the front end cap.

5. The condensate switch bracket needs to be attached in the correct orientation as shown in Figure 3.

   Important: Exercise caution while shooting the screw slowly through the opening; the end cap is made of plastic and can develop cracks on rough handling. See Figure 3.

   Figure 3: Diagram showing the correct orientation for installing the condensate switch bracket, with a detail emphasizing caution when screwing into the plastic end cap.

6. Route condensate overflow switch wiring along suction header and refrigeration line as shown in Figure 4, to joining plug at the top of the indoor section. Refer to unit schematic located on the compressor access panel for control box wiring locations.
