About This Manual
Literature Change History
Use this manual for UniTrane fan-coils and Force Flo cabinet heaters. This is the seventh revision of this manual. It provides specific installation, operation, and maintenance instructions for “ZO” and later design sequences for all models except low vertical, which are “SO” and later design sequences. For previous design sequence information, contact your local Trane representative.
Warnings and Cautions
Warnings and cautions appear at appropriate sections throughout this manual. Read these carefully.
WARNING
Indicates a potentially hazardous situation, which could result in death or serious injury if not avoided.
CAUTION
Indicates a potentially hazardous situation, which may result in minor or moderate injury if not avoided. Also, it may alert against unsafe practices.
CAUTION
Indicates a situation that may result in equipment or property-damage- only accidents.
WARNING
Hazardous Voltage w/Capacitors!
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 an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.
CAUTION
Use Copper Conductors Only!
Unit terminals are not designed to accept other type conductors. Failure to use copper conductors may result in equipment damage.
Common HVAC Acronyms
For convenience, a number of acronyms and abbreviations are used throughout this manual. These acronyms are alphabetically listed and defined below.

general information
General
UniTrane fan-coil and Force Flo units are intended for single zone applications. These units have load capabilities of 200 to 1200 cfm. See Figure I-GI-1 for unit components. Fan-coil units are available as two-pipe, with or without electric heat (one hydronic circuit) or four-pipe (two hydronic circuits). Force-Flo units feature two-pipe hydronic, electric heat only, or steam only. Also, these units feature a variety of factory mounted piping packages.
Units with the three-speed fan switch only, are available with the switch mounted on the unit, or shipped separately, to be mounted in the occupied space. The unit mounted three-speed
switch option, can be ordered with a low voltage(24 volts AC) transformer and three fan speed relays. The ship seperate three-speed switch option, only comes with a low voltage (24 volt AC) transformer and three fan speed relays.
The Tracer ZN010, ZN510, and ZN520 controllers are included inside the units control box assembly. These controllers utilize analog signals from a unit-mounted control device or from a control device mounted in the occupied space.
The controls interface option, includes a 24 volt AC transformer, and an interface terminal board. Controls provided by an external source, can be tied into the interface terminal board, utilizing 1/4" female spade connectors.
Model Number
Each UniTrane fan-coil and Force-Flo cabinet heater has a multiple character model number unique to that particular unit. To determine a unit’s specific options, reference the model number on the unit nameplate on the fan scroll. The unit nameplate also identifies the serial number, sales order number, and installation and operating specifications.
Following is a complete description of the fan-coil model number. Each digit in the model number has a corresponding code that identifies specific unit options.
