2.01 EQUIPMENT
A. General:
Indoor, direct-expansion, wall-mounted fan coil. Unit shall
be complete with cooling/heating (heat pump systems
only) coil, fan, fan motor, piping connectors, electrical
controls, microprocessor control system, and integral
temperature sensing. Unit shall be furnished with integral
wall-mounting bracket and mounting hardware.
B. Unit Cabinet:
Cabinet discharge and inlet grilles shall be attractively
styled, high-impact polystyrene. Cabinet shall be fully in-
sulated for improved thermal and acoustic performance.
C. Fans:
Fan shall be tangential direct-drive blower type with air in-
take at the upper front face of the unit and discharge at
the bottom front. Automatic, motor-driven vertical air
sweep shall be provided standard.
Air sweep operation shall be user selectable. Horizontal
direction may be manually adjusted (using remote con-
troller) and vertical air sweep may be manually set.
D. Coil:
Coil shall be copper tube with aluminum fins and galva-
nized steel tube sheets. Fins shall be bonded to the tubes
by mechanical expansion. A drip pan under the coil shall
have a drain connection for hose attachment to remove
condensate. Condensate pan shall have internal trap and
auxiliary drip pan under coil header.
NOTE: For refrigerant control, systems with the high wall
units use the piston refrigerant metering device in the
indoor unit.
E. Motors:
Motors shall be open drip-proof, permanently lubricated
ball bearing with inherent overload protection. Fan motors
shall be 3-speed.
F. Controls:
Controls shall consist of a microprocessor-based control
system which shall control space temperature, de-
termine optimum fan speed, and run self diagnostics. The
temperature control range shall be from 64 F to 84 F. The
unit shall have the following functions as a minimum:
1. An automatic restart after power failure at the same
operating conditions as at failure.
2. A timer function to provide a minimum 24-hour timer
cycle for system Auto. Start/Stop.
3. Temperature-sensing controls shall sense return-air
temperature. Indoor-air high discharge temperature
shutdown shall be provided.
4. Indoor coil freeze protection.
5. Wireless infrared remote control to enter set points
and operating conditions.
6. Auto Stop features shall have integral setback
control.
7. Automatic airsweep control to provide on or off acti-
vation of airsweep louvers.
8. Dehumidification mode shall provide increased latent
removal capability by modulating fan speed and set
point temperature.
9. Fan only operation shall provide room air circulation
when no cooling is required.
10. Diagnostics shall provide continuous checks of unit
operation and warn of possible malfunctions. Error
messages shall be displayed at the unit and at the re-
mote controller.
11. Fan speed control shall be user-selectable: high, me-
dium, low, or microprocessor automatic operation
during all operating modes
12. A time delay shall prevent compressor restart in less
than 3 minutes.
G. Filters:
Unit shall have filter track with factory-supplied cleanable
filters.
H. Electrical Requirements:
Unit shall operate on 208-v or 230-v, 60 Hz power supply
as specified on the equipment schedule. Power and con-
trol connections shall have terminal block connections.
I. 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 and
entering-air temperature at the evaporator coil of
F dry bulb and F wet bulb. Outdoor am-
bient temperature of air entering the condenser of
F.
2. The 619E system shall have a minimum listed SEER
(seasonal energy efficiency ratio) of at ARI
conditions.
3. Outdoor unit shall be rated at Decibels or less at
ARI conditions.
J. Refrigerant Lines:
All units shall have flare connections and a 90-degree
suction elbow shall be provided for rear connection.
K. Special Features (Field Installed):
1. Condensate Pump:
The condensate pump shall remove condensate from
the drain pan when gravity drainage cannot be used.
Pump shall be designed for quiet operation. Pump
shall consist of two parts: an internal reservoir/sensor
assembly, and a remote sound-shielded pump assem-
bly. The lift capability of the condensate pump shall be
3 to 25 feet. A level sensor on the condensate pan
shall stop cooling operation if the level in the conden-
sate pan is unacceptable.
2. Charcoal Filter Kit:
Kit shall include active charcoal filter(s) and required
collectors and/or frames. Filters shall aid in removing
volatile organic compounds and micro-particles from
the air in the conditioned space.
