four 0.20-in. engagement holes. Install a drain coupling assem-
bly using screws provided at each secondary drain hole loca-
tion. See Fig. 26. Do not attach any drain coupling assemblies
in the condenser section base rail.
Step 8 — Connect Condensate Drain — There
are a total of five drain connections required on each unit: one
primary drain (on right-hand side of the unit) and four second-
ary drains (two on each side of unit).
Using field-supplied fittings and pipe sections, assemble U-
traps at each secondary drain fitting. See Fig. 27. Provide a
minimum size of ½-in. pipe for secondary drains. Use a trap at
least 4-in. deep for size 030-070 units and 7-in. deep for size
075-100 units. Apply a bead of RTV or similar sealant around
the drain assemblies.
Consult local plumbing codes for direction on joining multi-
ple drain lines. Total size of any combined line does not need
to exceed nominal 2-in. size of primary drain connection.
PRIMARY DRAIN — The primary drain is a 2-in. FPT pipe
connection located on the right-hand side of the unit looking at
the unit from the return air end. See Fig. 12-21. Fig. 22 shows
the additional length of units with an extended chassis.
With field-supplied fittings and pipe sections, plumb the pri-
mary condensate drain to the 2-in. FPT connector on the base
rail. Use a trap height of at least 4-in. for size 030-070 units
and 7-in. for size 075-100 units. See Fig. 23 and 24. Install with
a height dimension of at least 2-in. from the top of the exit pipe
from the trap section to the bottom of the connector. Apply a
bead of RTV or similar sealant around the pipe joint at the con-
nector in the base rail.
Fill the U-traps at the secondary drain locations prior to unit
start-up. Also check the U-traps before each cooling season to
ensure the traps are filled and functioning properly.
SECONDARY
DRAINS
(Units

on
SECONDARY DRAINS (Units Installed on Steel Beam or
Slab) — There are two secondary drain connections required
on each side of the unit. There are secondary drains on the bot-
tom of the base rail on each side of the unit in the filter section
and on each side of the unit in the supply fan section. There are
labels marking each location on the unit base rail. See Fig. 12-
21. Drain holes will need to be drilled in these locations at the
side of the base rail. The existing secondary drain holes in the
bottom of the base rail must be sealed. Prior to final positioning
of the unit, apply a bead of RTV or similar sealant around each
secondary drain hole in the bottom of the unit base rail. See
Fig. 27. Install the metal seal plates then position the unit into
final location.
Curb) — There are two secondary drain connections on each
side of the unit. See Fig. 25. There are secondary drains on
each side of the unit in the filter section and on each side of the
unit in the supply fan section. There are labels marking each lo-
cation on the unit base rail. See Fig. 12-21.
Locate the four 11/4-in. drain coupling assemblies and
mounting screws (shipped in a bag taped to the basepan in the
supply fan section, located behind the access panel marked
FAN SECTION). The drain couplings are a 10-gage plate with
a 11/4 in. half coupling welded to the plate.
At each secondary drain hole location, there is a 13/8-in.

Locate the four 11/4-in. drain coupling assemblies and
mounting screws (shipped in a bag taped to the basepan in the
supply fan section, located behind the access panel marked
FAN SECTION). The drain couplings are a 10-gage plate with
a 11/4 in. half coupling welded to the plate.
4. Using field-supplied fittings and pipe sections, assemble
U-traps at each secondary drain fitting. See Fig. 24. Pro-
vide minimum size of ½-in. pipe for secondary drains.
Use a trap at least 4-in. deep for size 030-070 units and
7-in. deep for size 075-100 units.
After final positioning of the unit, perform the following
procedure:
5. Apply a bead of RTV or similar sealant around the drain
assemblies.
1. At each of the four secondary drain locations (marked
with labels on the unit base rail), position the drain cou-
pling assembly in the side of the base rail. Mark the
screw holes and the drain hole locations on the base rail.
Consult local plumbing codes for direction on joining multi-
ple drain lines. Total size of any combined line does not need to
exceed nominal 2-in. size of primary drain connection.
Fill the U-traps at the secondary drain locations prior to unit
start-up. Also check the U-traps before each cooling season to
ensure the traps are filled and functioning properly.
2. Drill holes for drain outlet (use 13/8-in. hole saw) and for
the mounting screws (use 3/16-in. drill bit).
3. Install a drain coupling assembly using screws provided
at each secondary drain hole location.

two (2) 500 MCM (maximum wire size) conductors per pole.
Step 11 — Route Field Wiring
UNIT SIZES 030-060 — Field wiring can be brought into the
unit through the basepan and roof curb or through the corner
post in the side of the unit next to the control box.
Units with Factory-Installed Disconnect — The factory-
installed disconnect is an interlocking, door-type. The discon-
nect handle locks the door when it is in the ON position. The
disconnect handle must be in the OFF position to open the con-
trol box door. The disconnect is located in the control box be-
hind the control box door for all units. See Fig. 42.
All field wiring must comply with NEC and all local codes.
Wire must be sized based on MCA (minimum circuit amps) on
the unit informative plate. See Fig. 43 for power wiring con-
nections to the unit disconnect and equipment ground.
A 31/2-in. FPT coupling for field power and a /4-in. FPT
3
coupling for 24 v control wiring are provided in the basepan.
There are two 7/8-in. pilot holes in the corner post as shown on
the certified drawings. Use these holes as pilot holes for mak-
ing the hole for field-supplied conduit in the corner post for
field power wiring.

If field power wiring is brought through the roof curb, route
wiring out through one of the holes to the field-supplied dis-
connect and then back into the unit through the other hole. See
Fig. 38 and 39 for recommended disconnect location.
If power wiring is brought through the side of the unit, route
wiring from field-supplied disconnect through top hole into
unit.
Operating Voltage — Operating voltage to the compressor
must be within the voltage range indicated on the unit name-
plate. Voltages between phases must be balanced within 2%,
and the current must be balanced within 10%. See Tables 10-25
for unit electrical data.
Use the following formula to determine the percentage of
voltage imbalance.
If control wiring is to be brought in through the side of the
7
unit, a /8-in. diameter hole must be drilled in the corner post
Voltage Imbalance
next to the control box.
UNIT SIZES 070-100 — Field wiring is brought into the unit
through the bottom of the control box. Wiring can be brought
through the roof curb through field-supplied watertight connec-
tions. See Fig. 40.
A 45/32-in. hole for field power wiring and a 7/8-in. hole for
24 v control wiring are provided in the bottom of the control
box. Field-supplied couplings must be used when routing wir-
ing into the control box.

IMPORTANT: Units with VFDs (variable frequency
drives) generate, use, and can radiate radio frequency
energy. If units are not installed and used in accordance
with these instructions, they may cause radio interfer-
ence. They have been tested and found to comply with
limits of a Class A computing device as defined by FCC
(Federal Communications Commission) regulations,
Subpart J of Part 15, which are designed to provide rea-
sonable protection against such interference when oper-
ated in a commercial environment.

Determine maximum deviation from average voltage:
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent voltage imbalance:
7
% Voltage Imbalance = 100 x

POWER WIRING — Units are factory wired for the voltage
shown on the unit nameplate. The main terminal block is suit-
able for use with aluminum or copper wires. Maximum wire
size varies according to disconnect size.
Units without Factory-Installed Disconnect — When install-
ing units, provide a disconnect per NEC (National Electrical
Code) of adequate size (MOCP [maximum overcurrent protec-
tion] of unit is on the informative plate). All field wiring must
comply with NEC and all local codes. Size wire based on
MCA (minimum circuit amps) on the unit informative plate.
See Fig. 41 for power wiring connections to the unit power
= 1.53%
This amount of phase imbalance is satisfactory as it is be-
low the maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is
more than 2%, contact local utility immediately.
Unit failure as a result of operation on improper line voltage
or excessive phase imbalance constitutes abuse and may cause
damage to electrical components.

location) so that location is controlled as closely to design pres-
sures as possible.
These units use a pressure transducer for sensing building
pressure. The BP transducer is located in the unit auxiliary con-
trol box. See Fig. 44 and 45 for auxiliary control box location.
See Fig. 46 and 47 for auxiliary control box details. Use a nom-
inal 1/4-in. plastic tubing.
Step 13 — Connect Air Pressure Tubing — Be-
fore options such as the variable frequency drive (VFD) and/or
modulating power exhaust can operate properly, the pneumatic
tubing for pressure sensing must be installed. Use fire-retardant
1
plenum tubing (field-supplied). All control devices use /4-in.
tubing. Tubing must be run from the appropriate sensing loca-
tion (in the duct or in the building space) to the control device
location in the unit.
VARIABLE FREQUENCY DRIVE — The tubing for the
duct pressure (DP) control option should sample supply duct
pressure approximately 2/3 of the way out from the unit in the
main trunk duct, at a location where a constant duct pressure is
desired.
On these units, the duct pressure is sensed by a pressure
transducer. The pressure transducer output is directed to the unit
control module. On all sizes, the DP transducer is located in the
unit auxiliary control box. See Fig. 44 and 45 for auxiliary
control box location. See Fig. 46-48 for auxiliary control box
details. Use a nominal 1/4-in. plastic tubing.
Refer to appropriate base unit Controls and Troubleshooting
book for instructions on adjusting set points for duct pressure
controls.
MODULATING POWER EXHAUST — The tubing for the
building pressure (BP) control (achieved via the modulating
power exhaust option) should sample building pressure in the
For instructions on adjusting BP control set points, refer to
the Controls and Troubleshooting book.
RETURN FAN POWER EXHAUST — The tubing for the
building pressure (BP) control (achieved via the return power
exhaust option) should sample building pressure in the area
near the entrance lobby (or other appropriate and sensitive lo-
cation) so that location is controlled as closely to design pres-
sures as possible.
The units use a pressure transducer for sensing building
pressure. The BP transducer is located in the unit auxiliary con-
trol box. See Fig. 45 for auxiliary control box location. See
Fig. 48 for auxiliary control box details. Use a nominal 1/4 in.
plastic tubing.
For instructions on adjusting BP control set points, refer to
the Controls and Troubleshooting book.

Step 20 — Install Optional Motormaster®
V
On size 040-060 units, in areas with prevailing winds of
more than 5 mph and where temperatures drop below 32 F,
wind baffles must be field fabricated to ensure proper cooling
cycle operation at low-ambient temperatures with Motormaster
V controls. Wind baffles are not needed on size 030, 035, and
070-100 units. See Fig. 70 for baffle details. Use 20-gage galva-
nized sheet metal, or similar corrosion-resistant material for the
baffles. Use field-supplied screws to attach baffles to unit.
Screws should be 1/4-in. diameter or larger. Screws should not
be more than 1/2-inch in length. Drill required screw holes for
mounting baffles.
Control — The Motormaster V control is a motor speed
control device which adjusts condenser fan motor speed in re-
sponse to varying liquid refrigerant pressure. A properly applied
Motormaster V control extends the operating range of air-condi-
tioning systems and permits operation at lower outdoor ambient
temperatures.
The optional Motormaster V controls are factory-installed.
Field-fabricated and installed wind baffles are also required for
units in areas with prevailing winds of more than 5 mph and
where temperatures drop below 32 F. The Motormaster V con-
trol permits operation of the unit to an ambient temperature of
–20 F. The control regulates the speed of one or two 3-phase fan
motors depending on unit size. Replacement of the fan motor on
most units is not necessary.
CAUTION
To avoid damage to refrigerant coils, electrical compo-
nents, and wiring use extreme care when drilling screw
holes and screwing in fasteners.

bus in a daisy chain arrangement. The positive pin of each
system element communication connector must be wired to the
positive pins of the system element on either side of it, the
negative pins must be wired to the negative pins, and the signal
pins must be wired to common pins. Wiring connections for
the CCN system should be made at the terminal block using the
screw terminals. The board also contains an RJ14 CCN plug
that can be used to connect a field service computer. There is
also another RJ14 LEN (Local Equipment Network) connec-
tion that is used to download software or connect a Naviga-
tor™ device.
NOTE: Conductors and drain wire must be 20 AWG minimum
stranded, tinned copper. Individual conductors must be insu-
lated with PVC, PVC/nylon, vinyl, Teflon, or polyethylene. An
aluminum/polyester 100% foil shield and an outer jacket of
PVC, PVC/nylon, chrome vinyl, or Teflon with a minimum
operating temperature range of –4 to 140 F (–20 C to 60 C) is
required. See Table 28 for cables that meet the requirements.

NOTE: If a cable with a different color scheme is selected, a
similar color code should be adopted for the entire network.
At each system element, the shields of its communication
bus cables must be tied together. If the communication bus is
entirely within one building, the resulting continuous field
must be connected to a ground at one point only. If the commu-
nication bus cable exits from one building and enters another,
the shields must be connected to grounds at the lightning
suppressor in each building where the cable enters or exits the
building (one point per building only).
To connect the unit to the network (Fig. 84):
1. Turn off power to the control box.
Table 28 — CCN Connection Approved
Shielded Cables
2. Cut the CCN wire and strip the ends of the red (+), white
(common) and black (–) conductors. (If a different net-
work color scheme is used, substitute appropriate colors.)
3. Wire the CCN to the screw terminals on the COMM
board as follows (Fig. 84):

To install a BT485 terminator, push the BT485 on to the
BT485 connector located near the BACnet connector.
NOTE: The BT485 terminator has no polarity associated with
it.
To order a BT485 terminator, consult Commercial Products
i-Vu® Open Control System Master Prices.
MS/TP WIRING RECOMMENDATIONS — Recommen-
dations are shown in Tables 29 and 30. The wire jacket and UL
temperature rating specifications list two acceptable alterna-
tives. The Halar specification has a higher temperature rating
and a tougher outer jacket than the SmokeGard specification,
and it is appropriate for use in applications where the user is
concerned about abrasion. The Halar jacket is also less likely to
crack in extremely low temperatures.
IMPORTANT: A shorted CCN bus cable will prevent
some routines from running and may prevent unit from
starting. If abnormal conditions occur, unplug the connec-
tor. If conditions return to normal, check CCN connector,
and run new cable if necessary. A short in one section of
the bus can cause problems with all system elements on
the bus.
Optional UPC Open Installation
WIRING THE UPC OPEN TO THE MS/TP NET-
WORK — The UPC Open controller communicates using
BACnet on an MS/TP network segment communications at
9600 bps, 19.2 kbps, 38.4 kbps, or 76.8 kbps.
Wire the controllers on an MS/TP network segment in a dai-
sy-chain configuration. Wire specifications for the cable are
22 AWG (American Wire Gage) or 24 AWG, low-capacitance,
twisted, stranded, shielded copper wire. The maximum length
is 2000 ft.
Install a BT485 terminator on the first and last controller on
a network segment to add bias and prevent signal distortions
due to echoing. See Fig. 85-87.
To wire the UPC Open controller to the BAS network:
1. Pull the screw terminal connector from the controller's
BAS Port.
2. Check the communications wiring for shorts and
grounds.
3. Connect the communications wiring to the BAS port’s
screw terminals labeled Net +, Net -, and Shield.
NOTE: Use the same polarity throughout the network
segment.
4. Insert the power screw terminal connector into the UPC
Open controller's power terminals if they are not current-
ly connected.
NOTE: Use the specified type of wire and cable for maximum
signal integrity.
Smoke Control Modes — Rooftop units can be used
for aid in building smoke control in the event of a building fire.
The available functions include: Fire Shutdown, Pressuriza-
tion, Evacuation, and Smoke Purge. These functions are
enhanced when multiple rooftop units are used to zone a build-
ing. See Table 31 and Fig. 82 and 83.
FIRE SHUTDOWN — Fire Shutdown mode terminates all
unit operation (cooling, heating, supply fan, and power
exhaust). This mode prevents recirculation of contaminated air
back into the space. The mode will not allow admission into
the space of unsuitable outside air. See Fig. 82 for wiring.
PRESSURIZATION — Pressurization mode is intended to
keep smoke out of a zone. The factory-installed optional econ-
omizer is required for this function. Pressurization is accom-
plished by the following:
• opening the economizer (option)
• running the supply fan (optional inlet guide vanes open
or optional VFD at normal duct static pressure set point)
• closing the power exhaust dampers (if installed as option
or accessory)
• shutting off the power exhaust fans (if installed as option
or accessory)
5. Verify communication with the network by viewing a
module status report. To perform a module status report
