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.

Failure to do so can result in fire, property damage,
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.

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.

INSTALLATION

PROCEDURE 1- CHECK EQUIPMENT
Unpack unit and move to final location. Remove carton taking care not

to damage unit. Inspect equipment for damage prior to installation. File
claim with shipping company if shipment is damaged or incomplete. Lo-

cate unit rating plate which contains proper installation information.

Check rating plate to be sure unit matches job specifications.

PROCEDURE 2- MOUNT FAN COIL

Unit can stand or lie on floor, or hang from ceiling or wall. Allow space

for wiring, piping, and servicing unit.

NOTE: To ensure proper drainage for horizontal installations, unit must
be installed so it is within 1/8 in. level of the length and width of unit.

A. Upflow Installation

If return air is to be ducted, install duct flush with floor. Set unit on floor

over opening. Only use return-air opening provided. All return air must

pass through the coil. (See Fig. 2.)

B. Modular Units

The EBV Fan Coil in size 6000 is a 2-piece modular unit. Modular
construction allows installer to disassemble unit into 2 components, coil

box and blower box, for ease of installation. (See Fig. 4)

To disassemble unit, remove rear corner brackets by removing 2
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.

SLOPE COIL

UNITS ONLY

CAUTION: For optimum condensate drainage performance in
horizontal installations, unit should be leveled along it's length

or raised 1/4" at the air inlet. The unit should also be pitched for-
ward 1/4" to 1/2" toward the front condensate drains.

NOTE: Modular units can be disassembled and components moved
separately to installation area for reassembly. This process accommo-

dates small scuttle holes and limiting entrances to installation sites.

leaks and cabinet sweating.

D. Manufactured and Mobile Home Housing Applications

1. Fan coil unit must be secured to the structure using field-supplied
hardware.

2. Allow a minimum of 24" clearance from access panels.

3. Recommended method of securing for typical applications

a. If fan coil is away from wall, attach pipe strap to top of fan coil
using No. 10 self tapping screws. Angle strap down and away
from back of fan coil, remove all slack, and fasten to wall stud of

Figure 3

Slope Coil In Horizontal Left Application

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.
