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 such as HCFCs and HFCs.
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).

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. 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.
WARNING
Rotating Components!
Failure to disconnect power before servicing could result in rotating
components cutting and slashing technician which could result in death or
serious injury.
Disconnect all electric power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the power can not be
inadvertently energized.
-
Ensure all power to the air handler has been disconnected and locked out.
-
Remove the evaporator fan and control access panels.
-
Disconnect all electrical motor leads from the motor.
-
Loosen tension adjustment bolts on the motor mount and remove the fan belt and motor sheave.
-
Remove the motor securing bolts and remove motor from the mount. If the oversize motor kit contains a fan sheave, remove the original sheave and install the one provided in the kit.
-
Install oversize motor on mount. Secure with bolts removed in Step 5. Determine the correct air flow needed using blower performance charts. From Table 2, select the correct number of turns the motor sheave is to be opened.
Grease motor shaft and install motor sheave, (use sheave provided in kits, or if sheave is not provided, reuse the old one), as close to the motor bearing as possible without touching. Tighten both set screws (turns open and key way set screw) to 130 inch pounds. -
Install new belt if provided in the kit, otherwise install belt that was removed in Step 4.
Adjust belt tension with adjusting bolts on the motor mount using instructions in Step 12.
NOTICE
Equipment Damage!
Proper adjustment of the fan belt is important to ensure optimal unit operation. Over or under tightening of the fan belt can result in belt slippage and excessive wear, bearing damage, sheave misalignment, and possible failure of fan motor mounts. -
On new “A” belts, pressing down half way between the pulleys with a force of 6 pounds, there should be 1/4-inch deflection. After the belt has stretched to its normal operating length, a force of 3 to 4 pounds should deflect the belt 1/4-inch.
On new “B” belts, pressing down half way between the pulleys with force of 9 pounds, there should be 1/4-inch deflection. After the belt has stretched to its normal operating length, a force of 4 to 6 pounds should deflect the belt 1/4-inch.
Note: There will normally be a rapid drop in tension during the run-in period. Tension new belts with one half (1/2) greater initial deflection force than the maximum recommended operating deflection force. Tension should be checked frequently during the first day. The correct operating tension for a “V” belt fan drive is the lowest tension at which the belt will not slip under peak load conditions. -
Check alignment of blower sheave with motor sheave using a straight edge and adjust blower sheave if necessary. Torque sheave set screw to 130 inch pounds.
WARNING
Live Electrical Components!
Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.
When it is necessary to work with live electrical components, have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. -
Reconnect wire leads at the motor, using connection label on motor or unit wiring diagram.
-
Secure wires so they do not make contact with any moving parts.
-
Being careful not to touch any electrical or moving parts, close the unit disconnect switch and check the indoor fan for proper rotation, alignment and minimum vibration.
Note: If fan is rotating backwards, open the unit disconnect switch and reverse any two (2) of the motor leads on the motor terminals or pigtail leads. (Applies to 3 Phase only). -
Once the proper rotation is verified, open the unit disconnect switch and
replace the control box cover and replace all panels. -
Close the unit disconnect switch and check unit operation.
