2.01 Equipment

A. General:
Indoor, direct- -expansion, wall- -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
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.
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. 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
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).
INDOOR WALL- - MOUNTED DUCT- - FREE UNITS
Size Range: 3/4 to 2 Ton Nominal Cooling Capacity / 3/4 to 2 Ton Nominal Heating Capacity
The unit shall have the following functions as a minimum:
10. Fan speed control shall be user- -selectable: high, medium,
11. Automatic heating- -to- -cooling changeover in heat pump
12. Indoor coil high temperature protection shall be provided to
G. Filters:
Unit shall have filter track with factory- -supplied cleanable filters.
H. Electrical Requirements:
Indoor fan motor to operate on 35VDC on model sizes 009- -012
and on 208- -230v on model sizes 018- -024, power is supplied from
outdoor unit.
I. Operating Characteristics:
The 40MVC, MVQ system 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):
33

Carrier Model Number: 40MVC/40MVQ
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.
low, or microprocessor controlled automatic operation
during all operating modes.
mode. Control shall include deadband to prevent rapid
mode cycling between heating and cooling.
detect excessive indoor discharge temperature when unit is
in heat pump mode.
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.
