PART 2 -- PRODUCTS
2.01 Equipment
A. General:
Indoor, direct--expansion, floor--mounted fan coil. Unit shall be
complete with cooling/heating coil, fan, fan motor, piping
connectors, electrical controls, microprocessor control system, and
integral temperature sensing. Unit shall be furnished with integral
mounting bracket and mounting hardware.
B. Unit Cabinet:
Cabinet discharge and inlet grilles shall be attractively styled,
high--impact polystyrene. Cabinet shall be fully insulated for
improved thermal and acoustic performance.
C. Fans:
1. Fan shall be tangential direct--drive blower type with air
intake in the center of the unit and discharge at the top and
bottom front. Automatic, motor--driven vertical air sweep
shall be provided standard.
2. Air sweep operation shall be user selectable. The vertical
sweep may be adjusted (using the remote control) and the
horizontal air direction may be set manually.
D. Coil:
Coil shall be copper tube with aluminum fins and galvanized steel
tube sheets. Fins shall be bonded to the tubes by mechanical
expansion and specially blue hydrophilic pre--coated for enhanced
wet--ability. A drip pan under the coil shall have a drain connection
for hose attachment to remove condensate. Condensate pan shall
have internal trap.
E. Motors:
Motors shall be open drip--proof, permanently lubricated ball
bearing with inherent overload protection. Fan motors shall be
4--speed.
F. Controls:
Controls shall consist of a microprocessor--based control system
which shall control space temperature, determine optimum fan
speed, and run self diagnostics. The temperature control range
shall be from 62
_
F to 86
_
F (17
_
C to 30
_
C) in increments of 1
_
F
or 1
_
C, and have 46
_
F Heating Mode (Heating Setback). The
wireless remote controller shall have the ability to act as the
temperature sensing location for room comfort.
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.
4. Indoor coil freeze protection.
5. Wireless infrared remote control to enter set points and
operating conditions.
6. Automatic air sweep control to provide on or off activation
of air sweep louvers.
7. Dehumidification mode shall provide increased latent
removal capability by modulating system operation and set
point temperature.
8. Fan--only operation to provide room air circulation when no
cooling is required.
9. Diagnostics shall provide continuous checks of unit
operation and warn of possible malfunctions. Error
messages shall be displayed at the unit.
10. Fan speed control shall be user--selectable: high, medium,
low, or microprocessor controlled automatic operation
during all operating modes.
11. Automatic heating--to--cooling changeover in heat pump
mode. Control shall include deadband to prevent rapid
mode cycling between heating and cooling.
12. Indoor coil high temperature protection shall be provided to
detect excessive indoor discharge temperature when unit is
in heat pump mode.
G. Filters:
Unit shall have filter track with factory--supplied cleanable filters.
H. Electrical Requirements:
Indoor fan motor to operate on 208--230V as specified. Power is
supplied from the outdoor unit.
I. Operating Characteristics:
The 40MB*F system shall have a minimum SEER (Seasonal
Energy Efficiency Ratio) and HSPF at AHRI conditions, as listed
on the specifications table.
J. Refrigerant Lines:
All units should have refrigerant lines that can be oriented to
connect from the left, right or back of unit. Both refrigerant lines
need to be insulated.
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 assembly. A liquid level
sensor in the reservoir shall stop cooling operation if the
liquid level in the reservoir is unacceptable.
