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 insulated for
improved thermal and acoustic performance.
C. Fans:
1. Fan shall be tangential direct- -drive blower type with air
intake at the top of the unit and discharge at the bottom
front. Automatic, motor- -driven vertical air sweep shall be
provided standard. Automatic motor- -driven horizontal air
sweep shall be provided standard on sizes 030 and 036.
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 on unit sizes
018 and 024.
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 coated for enhanced wetability. A drip
pan under the coil shall have two drain connections for hose
attachment, on either the left or right- -hand side, 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
3- -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 84_F (16.67_C to 28.89_C).
User interface with the unit shall be accomplished through the
standard wireless remote control (can be configured for _F or _C)
or an optional wired controller or Zone Manager.
Carrier Model Number: 40QNC/40QNQ
Size Range: 1- -1/2 to 3 Ton Nominal Cooling Capacity /1- -1/2 to
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. Automatic vertical air sweep control to provide on or off
activation of air sweep louvers. Automatic horizontal air
sweep is available on sizes 030 and 036.
6. Dehumidification mode shall provide increased latent
removal capability by modulating system operation and set
point temperature.
7. Fan- -only operation to provide room air circulation when no
cooling is required.
8. Diagnostics shall provide continuous checks of unit
operation and warn of possible malfunctions. Error
messages shall be displayed at the unit.
9. Fan speed control shall be user- -selectable: high, medium,
low, or microprocessor controlled automatic operation
during all operating modes.
10. Automatic heating- -to- -cooling changeover in heat pump
mode. Control shall include deadband to prevent rapid
mode cycling between heating and cooling.
G. Filters:
Unit shall have filter track with factory- -supplied cleanable filters.
H. Electrical Requirements:
Indoor units shall be 208/230- -1- -60 and require their own power
supply. Only control wiring shall run between the indoor and
outdoor units.
I. Operating Characteristics:
The 40QNC/QNQ, when matched with the appropriate outdoor
section, shall have a minimum listed SEER (seasonal energy
efficiency ratio) of 13 at ARI conditions, and a minimum HSPF of
7.7.
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.
2. Wired Control:
- - The wired control can replace the standard wireless
control and provide the User Interface to control one unit or
up to 6 units daisy- -chained together.
3. Zone Control:
- - The Zone Control can provide the capability of
connecting up to 32 units into one or up to 8 independent
zones. Each zone can be programmed for 7 days with each
day having up to 4 periods.
