PART 2 – PRODUCTS
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 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 useable selectable. The vertical
sweep may be adjusted (using the remote control) and the
horizontal air direction maybe 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 (16.7_C to 28.9_C).
The unit shall have the following functions as a minimum:
1. Automatic restart after power failure at the same operating
conditions as at failure.

INDOOR WALL- - MOUNTED DUCT- - FREE UNITS
Size Range: 3/4 and 1 Ton Nominal Cooling and Heating Capacity
2. A timer function to provide a minimum 24-hour timer cycle
for system Auto Start/Stop.
3. Temperature sensing control to enter set points and
operating conditions.
4. Wireless infrared remote control to enter set points and
operating conditions.
5. Automatic air sweep control to provide on or off activation
of air sweep louvers.
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.
The unit shall be protected against the following:
1. Indoor coil freeze up
2. Indoor coil high temperature protection shall be provided to
detect excessive indoor discharge temperature when unit is
in heat pump mode.
G. Filters:
Units shall have filter track with factory-supplied cleanable filters.
H. Electrical Requirements:
Indoor fan motor to operate 115 volts on sizes 009-012. Power is
supplied from the indoor unit.
I. Operating Characteristics:
The 40GXC(Q) system shall have a minimum listed SEER
(seasonal energy efficiency ratio) of 16 SEER at ARI conditions,
and a minimum HSPF of 7.7.
J. Refrigerant Lines:
All units should have refrigerant line connections that can be
oriented to connect from the left, right, or back of unit. Both
refrigerant lines need to be insulated (on heat pump units).
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.
