About This Manual
Literature Change History
Use this manual for UniT rane 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 T rane 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.
WARNING
Hazardous V oltage 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.
BAS = Building automation systems
cfm = Cubic-feet-per-minute
ewt = entering water temperature
F/A = Fresh air
HV AC = Heating, ventilation and air
conditioning
I/O = Inputs/outputs
IOM= Installation, operation, and
maintenace manual
LH = Left-hand
O/A = Outside air
R/A = Return air
RH = Right-hand
rpm = Revolutions-per-minute
S/A = Supply air
w.c. = W ater column
ZSM = Zone sensor module
CAUTION
Indicates a situation that may result
in equipment or property-damageonly accidents.
UniT rane 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
Factory installed
and tested controls
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 T racer 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
female spade connectors.

Model Number
Each UniT rane fan-coil and Force-Flo
cabinet heater has a multiple character
model number unique to that particular
unit. T o 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.
