personal injury or death.
The blower cabinet may be used for cooling or heat pump operation with
or without electric heat. The cabinet can be installed in an upflow or
horizontal position (Figure 2, 3). EBV models are shipped with the hori-
zontal kit already installed.
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 con-
nections, 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 Fig. 1).
NOTE: Internal filter can be accessed from separate filter door. If the
filter can NOT be easily accessed, a remote filter is recommended. Re-
fer to ACCA Manual D for remote filter sizing.

screws which secure brackets. (See Fig. 4) Remove either 2 screws in
each front corner of coil box, or 2 screws in blower box. Do not remove
all 4 screws in each corner. (See Fig. 4) Sections may now be separated
by lifting top section from lower section. To reassemble, reverse above
procedure. Be certain to reinstall all fasteners when reassembling.
C. Horizontal Installation
Be sure installation complies with all applicable building codes that may
require installation of secondary condensate pan.
1. Arrange support for unit by setting it in or above secondary conden
sate drain.
2. When suspending unit from ceiling, dimples in casing indicate proper
location of screws for mounting metal support straps (See Fig. 3)
CAUTION
A field fabricated auxiliary drain pan, with a seperate drain is RE-
QUIRED for all installations over a finished living space or in any
area that may be damaged by overflow from a restricted main drain
pan. In some localities, local codes require an auxiliary drain pan
for ANY horizontal installation.

structure using 5/16-in. lag screws. Typically both sides of fan
coil.
b. If fan coil is against wall, secure fan coil to wall stud using
1/8-in. thick right-angle brackets. Attach brackets to fan coil us
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.

PROCEDURE 4-ELECTRICAL CONNECTIONS
On units with a factory installed disconnect with pull-out removed, ser-
vice and maintenance can be safely performed on only the load side of
the control package.
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 per-
formed until the main disconnect switch (remote to the unit) is
turned off. Failure to do so will result in electrical shock causing
personal injury or death.
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
wiring. 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
disconnect switch located within sight from and readily accessible from
the unit.

A. Line Voltage Connections
if unit contains an electric heater, remove and discard power plug from
fan coil and connect male plug from heater to female plug from unit wir-
ing harness. (See Electric Heater Installation Instructions.)
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.
NOTE: Units installed without electric heat should have a field-supplied
sheet metal block-off plate covering the heater opening. This will re-
duce air leakage and formation of exterior condensation.
WARNING: Before installing or servicing system, always turn off
all power to system. There may be more than I disconnect
switch. Turn off accessory heater power if applicable. Electrical
shock can cause personal injury or death.
CAUTION: If a disconnect switch is to be mounted on the unit, se-
lect a location where drill or fastener will not contact electrical or
refrigerant components. Electrical shock can cause personal
injury or death.
NOTE: Before proceeding with electrical connections, make certain that
supply voltage, frequency, and phase are as specified on unit rating
plate. Be sure that electrical service provided by the utility is sufficient
to handle the additional load imposed by this equipment. See unit wir-
ing label for proper field high- and low-voltage wiring. Make all electri-
cal connections in accordance with 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 disconnect
switch located within sight from, and readily accessible from the unit.

Installation Instructions
Figure 11 Wiring Layout Air Conditioning Unit
Wire low voltage in accordance with wiring label on the blower. (See Fig.
8, 10, 11, 12, 13 and 14). Use no. 18 AWG color-coded, insulated (35
C minimum) wire to make the low-voltage connections between the
thermostat, the unit, and the outdoor equipment. If the thermostat is lo-
cated more than 100 ft. from the unit (as measured along the low-volt-
age wire), use No. 16 AWG color-coded, insulated (35 C minimum)
wire. All wiring must be NEC Class 1 and must be separated from in-
coming power leads. Refer to outdoor unit wiring instructions for any
additional wiring procedure recommendations.
TRANSFORMER INFORMATION
Transformer is factory-wired for 230v operation. For 208v applications,
disconnect the black wire from the 230v terminal on transformer and
connect it to the 208v terminal. (See Fig. 14).
HEATER STAGING
The controls are factory circuited for single-stage operation. When 2
or 3 stages are desired, remove J2 (Jumper-2) from the control board.

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 accordance with existing electrical codes. If conduit
position 0 (off) or 1 (on) as specified on blower charts.
Set switches 1 and 2 to position 0 (off) or 1 (on) as specified in Figure 12
to control Fan delay ON - OFF.
NOTE: Power must be completely OFF to unit any time switch
settings are changed or settings will not take effect.
Adding Humidistator Outdoor Thermostat
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. Fan Control Board Jumper Instructions
The fan control board (see Fig. 8) has two jumpers. Jumper 1 (JP1)
jumpers two of three pins. The control unit should be factory set to the
VS (variable speed) position and should be left in this position in most
cases.
If there is a motor or control failure, and a variable speed replacement is
not readily available, it may be necessary to use a PSC motor until the
proper part can be ordered. This "limp mode" can be accessed by
moving JP 1 to the PSC pins. In this position a PSC motor can replace the
VS motor.
Jumper 2 (J2) is used to stage electric heaters. When in place, J2 ties
Wl and W2 together which should be used for single stage heat. When
J2 is removed, it allows Wl and W2 to be controlled separately and is for
applications using two stage electric heating.
MotorSpeedsand Airflow
See Figure 15
The motor speed can be set on one of eight speeds and the air flow will
adjust between 60%, 80% and 100% depending on settings. Time ON /
OFF settings can also be adjusted.
Determine coil static pressure drop, consult coil manual and measure
duct system static pressure, then determine required speed setting
from blower charts.
For Cooling/HP Heating - Set switches 6, 7, and 8 on the motor control
to position 0 (off) or 1 (on) as specified on blower charts.
Adding a humidistat or outdoor thermostat allows the airflow to be
reduced to 80% of normal allowing greater humidity control.
Humidistats are preferred but an outdoor thermostat can be used but
can only be set based on temperature. Suggested starting point is 85 F,
but this will vary depending on several factors.
The control must be wired differently on air conditioners and heat
pumps. On air conditioners connect to Y and Dehum terminals H, (see
Figure 10).
HEAT PUMPS ONLY: Heat pumps must use only the outdoor
thermostat, because it is powered instead of just performing a switching
function. This allows it to be out of the circuit when continuous
circulation is desired, which is required for the system to operate on Fan
Only for circulation, which is 60% airflow. On heat pumps connect to Y
and Dehum terminals H, and C and O to power the outdoor thermostat
(see Figure 12).
NOTE: The outdoor thermostat is not used for this application and if W
and H are energized at the same time, the unit will not run. The powered
outdoor thermostat only allows H to be energized when the system is
in the cooling mode.
PROCEDURE 5-REFRIGERANT TUBING AND FLOW CONTROL
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 out-
door unit service valves.
CAUTION: Braze with SiI-Fos or Phos-copper on copper to cop-
per joints and wrap a wet cloth around rear of fitting to prevent
damage to TXV.
CAUTION: If using an EBV model with a TXV in conjunction with
a single-phase reciprocating compressor, a compressor hard
start kit is required.

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. 17). 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. 18).
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
condensate 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 con-
densate 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 noticeable. The owner of the structure must be informed that
when condensate flows from the secondary drain or external conden-
sate pan, the unit requires servicing or water damage will occur.
