Indoor, direct-expansion, low-profile (11
3
⁄ 4 -in. high) in-
ceiling fan coil. Unit shall come complete with cooling/
heating coil, electric heater, fan, fan motor, piping
connectors, electrical controls, condensate pump, and
hanging brackets.
B. Unit Cabinet:
Cabinet shall be constructed of zinc-coated steel. Fully
insulated discharge and inlet grilles shall be attractively
styled, high-impact polystyrene. Cabinet shall have filter
tracks and cleanable filters which shall be accessible from
below with a
1
⁄ 4 -turn fastener. Adjacent room cooling to be
provided by a simple knockout in the cabinet side panel,
and cabinet shall have provisions to accommodate a lim-
ited amount of ductwork, if desired.
C. Fan:
Fan shall be a centrifugal, direct-drive blower type with
air intake in center of the unit and discharge on the
perimeter. Air louvers shall be adjustable for 2, 3, or 4-way
discharge.
D. Coil:
Coil shall be copper tube with aluminum fins and gal-
vanized steel tube sheets. Fins will be bonded to the
tubes by mechanical expansion. A drip pan under the coil
shall have a factory-installed condensate pump and drain
connection for hose attachment to remove condensate.
E. Motors:
Motor shall be totally enclosed and permanently lubri-
cated with inherent protection. Fan motor shall be
3-speed.
F. Electric Heater:
Units shall be equipped with factory-mounted electric
heaters. Minimum protections shall include overcurrent
and high temperature protection.
G. Controls:
Controls shall be 24 v, and shall be easily operated by
the user from a wall-mounted control unit. Float control
shall be in the condensate sump to shut unit down in case
of pump malfunction. A wall-mounted electro-mechanical
thermostat with 3 fan-speed selections and an auto/
manual switch shall be supplied for field installation.
Automatic changeover from cooling to heating modes and
selectable 2 or 4 minute start-up delay shall be included.
The R-22 refrigerant shall be controlled with a piston-type
refrigerant metering device, and evaporator coil freeze
protection shall be provided.
H. Filters:
Unit shall have filter track with factory-supplied cleanable
filters.
I. Electrical Requirements:
Unit shall operate on a 208-v or 230-v, 60 Hz power sup-
ply as specified on the equipment schedule.
J. Operating Characteristics:
1. The unit shall be matched with an outdoor unit. The
combination of the outdoor unit and the indoor-fan
coil unit shall have a total net cooling capacity of
Btuh or greater at conditions of fan
speed with entering-air temperature at the evaporator
coil of
F dry bulb and F wet bulb. Out-
door ambient temperature of air entering the con-
denser of
F.
2. The system shall have a minimum listed SEER (sea-
sonal energy efficiency ratio) of
at ARI condi-
tions, and a minimum HSPF of
.
3. Heating capacity shall be
Btuh or greater at
conditions of
fan speed with entering-air tem-
perature at indoor coil of
F dry bulb and out-
door ambient of
F dry bulb and F wet
bulb.
K. Special Features (Field Installed):
1. Power Ventilation Kit:
Kit shall allow ventilation of the conditioned space with
outdoor air. The kit shall include filter, booster fan, and
controls.
2. Electronic Programmable Thermostat:
