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
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 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). 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.

Installation
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing 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. Verify that no power is present with a voltmeter.
1. Read instructions carefully. Failure to follow them could damage the
product or cause hazardous condition.
2. Check ratings given in instructions and on product to make sure the
product is suitable for your application.
3. Installer must be a trained and experienced service technician.
4. See Figure 1 for actuator dimensions, and Figure 3 for exploded view.
5. Always conduct a thorough check-out when installation is completed.
6. While not necessary to remove the actuator from the body, it can be
removed for ease of installation. The orientation of the actuator must
be set as shown in Figure 2.
7. An extra 4 inches (101 mm) head clearance above the actuator is
required to remove the actuator.
Note: For trouble-free operation of the product, good installation
practice must include initial system flushing, chemical water treatment,
and the use of a 50 micron (or finer) system side stream filter(s).

The manual lever on the actuator is used as a position indicator and as
a manual opener for putting the valve in full open position to allow initial
system flushing.
Do not use boiler additives, solder flux, and wetted materials. These are
petroleum based or contain mineral oil, hydrocarbons, or ethylene
glycol acetate. Compounds which can be used, with minimum 50%
water dilution are diethylene glycol, ethylene glycol, and propylene
glycol (antifreeze solution).
Plumbing
In mixing applications the valve is installed with inlet to A, bypass to B
and outlet through AB.
For 2-way or 3-way control, mount the valve directly in the tube or pipe.
Do not grip actuator while making and tightening up plumbing
connections. Hold valve body in your hand or attach adjustable spanner
across hexagonal or flat faces of valve body. If assembling valve train on
a bench, take care not to deform body with vice. Excess jaw force can
deform body.
Installing Replacement Actuator
Note: Installation of a new actuator does not require draining the
system, provided the valve body remain in the pipeline.
1. Check replacement part number and voltage ratings for match with
old device.
2. Disconnect power supply before servicing to avoid electrical shock or
equipment damage.
3. Disconnect lead wires to actuator. Where appropriate, label wires for
rewiring.
4. Remove the screw attaching actuator to valve.
5. Install new actuator by matching the positions of the square shaft and
actuator stem.
6. Match locating pins to mating holes.
7. Screw actuator to valve body hand tight.
8. Reconnect lead wires.
9. Restore power and check-out operation.
Manual Operation
The valve can be manipulated to any position manually as required. To
manually operate the valve, simultaneously press the manual button
and rotate the lever to the desired position (see Figure 5). The manual
open position may be used for filling, venting and draining the system,
or for opening the valve in case of power failure. The valve and actuator
will return to the automatic position when power is restored.
Figure 5. Manual operation
Do NOT rotate the
lever before pressing
the button.
Wiring
One controller is required to operate each valve. A common controller
may be used with isolation relays between each actuator. Actuator
interaction can result otherwise. Figure 6 shows single unit wiring
connections. Port “A” open and closed denote valve open and closed
positions respectively.
