General Information
Installation or repairs made by unqualified persons
can result in hazards to you and others. Installation
MUST conform with local building codes and with the
National Electrical Code NFPA70 current edition.
The information contained in this manual is intended
for use by a qualified service technician familiar with
safety procedures and equipped with the proper tools
and test instruments,
Failure to carefully read and follow all instructions in
this manual can result in equipment malfunction,
property damage, personal injury and/or death.
The blower cabinet may be used for cooling or heat pump operation with
or without electric heat. Installations without electric heat, require a No
Heat Kit.The cabinet can be installed in an upflow or horizontal position
(Figure 2, 3). Horizontal installations require a horizontal kit. Some
models are shipped with the horizontal kit already installed. EBP units
are not shipped with air filters installed. Filter must be field installed.
Washable filters are available as an accessory.
Location
Select the best position which suits the installation site conditions. The
location should provide adequate structural support, space in the front
of the unit for service access, clearance for return air and supply duct
connections, space for refrigerant piping connections and condensate
drain line connections. If heaters are being installed make sure ade-
quate clearance is maintained from supply ductwork, See Clearances
and Warning in Figure 1.
NOTE: Internal filter can be accessed from separate filter door. If the fil-
ter can NOT be easily accessed, a remote filter is recommended. Refer
to ACCA Manual D for remote filter sizing.
If the unit is located in an area of high humidity, nuisance sweating of
casing may occur. On these installations a wrap of 2" fiberglass insula-
tion with a vapor barrier is recommended.

ing No. 10 self tapping screws and to wall stud using 5/16-in. lag
screws. (See Fig. 9).
PROCEDURE 2-AIR DUCTS
Connect supply-air duct over the outside of 3/4-in. flanges provided on
supply-air opening. Secure duct to flange, using proper fasteners for
type of duct used, and seal duct-to-unit joint. If return-air flanges are
required, install factory authorized accessory kit.
Use flexible connectors between ductwork and unit to prevent transmis-
sion of vibration. When electric heater is installed, use heat-resistant
material for flexible connector between ductwork and unit at discharge
connection. Ductwork passing through unconditioned space must be in-
sulated and covered with vapor barrier.
Ductwork Acoustical Treatment
Metal duct systems that do not have a 90 degree elbow and 10 ft. of main
duct to first branch takeoff may require internal acoustical insulation lin-
ing. As an alternative, fibrous ductwork may be used if constructed and
installed in accordance with the latest edition of SMACNA construction
standard on fibrous glass ducts. Both acoustical lining and fibrous duct-
work shall comply with National Fire Protection Association as tested by
UL Standard 181 for Class 1 air ducts.

low voltage circuit protective fuse (5 amp.), fan motor speed tapselec-
tion terminal (SPT), and time delay relay (TDR) jumper. To disable the
TDR feature, sever the jumper wire JW1. (See Fig. 8.)
A restrictor orifice is located in a fitting at the distributor. The factory
installed restrictor orifice is identified on the unit rating plate.
The restrictor orifice may require changing to obtain best performance.
Refer to the restrictor charts furnished with the outdoor unit.
CAUTION: If a disconnect switch is to be mounted on unit, select
a location where drill or fastener will not contact electrical or re-
frigerant components,
Before proceeding with electrical connections, make certain that supply
voltage, frequency, phase, and ampacity are as specified on the unit rat-
ing plate. See unit wiring label for proper field high- and low-voltage wir-
ing. Make all electrical connections in accordance with the NEC and any
local codes or ordinances that may apply. Use copper wire only. The unit
must have a separate branch electric circuit with a field-supplied dis-
connect switch located within sight from and readily accessible from the
unit.

WARNING:Field wires on the line side of the disconnect found in
the fan coil unit remain live, even when the pull-out is removed.
Service and maintenance to incoming wiring can not be performed
until the main disconnect switch (remote to the unit) is turned off.
Failure to do so will result in electrical shock causing personal in-
jury or death.
On units with a field installed disconnect with pull-out removed, service
and maintenance can be safely performed on only the load side of the
control package.
A. Line Voltage Connections
EBP / EBX units installed without electric heat require the use of a facto-
ry-authorized Power Plug Kit (EBACO1PLG1). This kit provides the
electrical connections necessary to supply the EBP unit with 230-v pow-
er when electric heat is not present. This kit is required only on those
EBP****A and EBX model applications which do not use electric heat.
For units without electric heat:
1. Connect 208/230v power leads from field disconnect to yellow and
black stripped leads.
2. Connect ground wire to unit ground lug.
3. When installing an electric heater, remove and discard power plug (if
equipped) from fan coil and connect male plug from heater to female
plug from unit wiring harness. (See Electric Heater Installation instruc-
tions.)

CONNECTION TO UNIT
Wire low voltage in accordance with wiring label on the blower. (See Fig.
8, 1O, 11,12, 13and 14). Use no. 18 AWG color-coded, insulated (35 C
minimum) wire to make the low-voltage connections between the ther-
mostat, the unit, and the outdoor equipment. If the thermostat is located
more than 100 ft. from the unit (as measured along the low-voltage
wire), use No. 16 AWG color-coded, insulated (35 C minimum) wire. All
wiring must be NEC Class 1 and must be separated from incoming pow-
er leads. Refer to outdoor unit wiring instructions for any additional wir-
ing procedure recommendations.
TRANSFORMER INFORMATION
Transformer is factory-wired for 230v operation. For 208v applica-
tions, disconnect the black wire from the 230v terminal on transformer
and connect it to the 208v terminal. (See Fig. 15).
HEATER STAGING
CAUTION: If W2, W3, and E on any 3 stage heater (18, 20, 24, or
30kw), are individually connected as with outdoor thermostats or
any other situation, emergency heat relay must be used.
The controls are factory circuited for single-stage operation. When 2
stages are desired, cut W3 at the W2 wire nut, strip and reconnect per
the thermostat kit instruction. (See Fig. 13). When 3 stages are desired,
cut the W2 wire nut off and discard. Strip W2, W3, and E and reconnect
per thermostat kit instructions. (See Fig. 14).

C. Ground Connections
WARNING: According to NEC, ANSI/NFPA 70, and local codes, the
cabinet must have an uninterrupted or unbroken ground to mini-
mize personal injury if an electrical fault should occur. The ground
may consist of electrical wire or metal conduit when installed in ac-
cordance with existing electrical codes. If conduit connection uses
reducing washers, a separate ground wire must be used. Failure
to follow this warning could result in electric shock, fire, or death.
NOTE: Use UL-listed conduit and conduit connector for connecting
supply wire(s) to unit to obtain proper grounding. Grounding may also
be accomplished by using grounding lugs provided in control box.
D. Minimum CFM and Motor Speed Selection
Units with or without electric heaters require a minimum CFM Refer to
the unit wiring label to ensure that the fan speed selected is not lower
than the minimum fan speed indicated.
Fan speed selection is done at the fan relay electronic fan board. To
change motor speeds, disconnect fan lead used on relay terminal (SPT)
and replace with motor speed tap desired. (See Fig. 16). Save insulating
cap and place on motor lead removed from relay.
NOTE: In low static applications, lower motor speed tap should be used
to reduce possibility of water being blown off coil.
All units have 2 or 3 motor speed taps. Low speed (red) is designed for
mismatch outdoor unit applications. Medium speed (blue) is designed
forstraight matched operations. High speed (black) is used with high ex-
ternal static duct systems of straight matched systems.
PROCEDURE 4-REFRIGERANT TUBING
Field-supplied tubing must be of refrigerant grade. Suction tube must
be insulated. Do not use damaged, dirty, or contaminated tubing be-
cause it may plug refrigerant flow-control device. ALWAYS evacuate
the coil and field-supplied tubing to 500 microns before opening outdoor
unit service valves.
CAUTION: Braze with Sil-Fos or Phos-copper on copper to copper
joints and wrap a wet cloth around rear of fitting to prevent damage
to TXV.
PROCEDURE 5-REFRIGERANT FLOW-CONTROL DEVICE
CAUTION: If using an EBX or an EBP model with field installed TXV
in conjunction with a single-phase reciprocating compressor, a
compressor hard start kit is required.
Check piston size shown on indoor unit rating plate to see if it matches
required piston shown on outdoor unit rating plate. If it does not match,
replace indoor piston with piston shipped with outdoor unit. The piston
shipped with outdoor unit is correct for any approved indoor coil com-
bination. (See Fig. 17). When changing piston, use a back-up wrench.
Hand tighten hex nut, then tighten with wrench 1/2 turn. Do not exceed
30 ft-lbs.

PROCEDURE 6-CONDENSATE DRAINS
Units are equipped with primary and secondary 3/4-in. FPT drain con-
nections. For proper condensate line installations see Fig. 2, 3, 5, 6 and
7. To prevent property damage and achieve optimum drainage perfor-
mance, BOTH primary and secondary drain lines should be installed
and include properly-sized condensate traps. (See Fig. 18). Factory-
approved condensate traps are available (Kit No. EBAC01CTK1). Be
sure to install plastic push-in plugs in unused condensate drain fittings.
it is recommended that PVC fittings be used on the plastic condensate
pan. Finger-tighten plus 1-1/2 turns. Do not over-tighten. Use pipe
dope.
CAUTION: Shallow, running traps are inadequate and DO NOT al-
low proper condensate drainage. (See Fig. 19).
NOTE: When connecting condensate drain lines, avoid blocking filter
access panel, thus preventing filter removal. After connection, prime
both primary and secondary condensate traps.
NOTE: if unit is located in or above a living space where damage may
result from condensate overflow, a field-supplied, external condensate
pan should be installed underneath the entire unit, and a secondary con-
densate line (with appropriate trap) should be run from the unit into the
pan. Any condensate in this external condensate pan should be drained
to a noticeable place. As an alternative to using an external condensate
pan, some localities may allow the use of a separate 3/4-in. condensate
line (with appropriate trap) to a place where the condensate will be no-
ticeable. The owner of the structure must be informed that when conden-
sate flows from the secondary drain or external condensate pan, the unit
requires servicing or water damage will occur.
