2.01 Equipment
A.
General:
Indoor, direct-- expansion, ceiling--mounted fan coil. The unit is
complete with a cooling/heating coil, fan, fan motor, piping
connectors, electrical controls, microprocessor control system, and
integral temperature sensing.
B, Unit Cabinet:
Unit cabinet is constructed of galvanized steel. Cabinet is fully
insulated for improved thermal and acoustic performance.
C. Fans:
Fans are the tangential direct--drive blower type with an air intake
at the rear or bottom of the unit and discharge at the front.
D. Coil:
The coil is a copper tube with aluminum fins and galvanized steel
tube sheets. Fins are bonded to the tubes by mechanical expansion
and blue hydrophilic pre--coated for enhanced wet--ability. A drip
pan under the coil has a factory installed condensate pump and
drain connection for hose attachment to remove condensate.
E. Motors:
The motors are open drip--proof, permanently lubricated ball
bearing with inherent overload protection. Fan motors are 3--speed.
F. Controls:
Controls consist of a microprocessor-- based control system which
the control space temperature, determines the optimum fan speed,
and runs self diagnostics. The temperature control range is from
62_Fto86_F(17_Cto30_C) in increments of 1_For1_C, and
has 46_F Heating Mode (Heating Setback). The wireless remote
controller can 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 that provides a minimum 24 -- hour timer
cycle for system Auto Start/Stop.
3. Temperature--sensing controls that senses the return air
temperature.
4. Indoor coil freeze protection.
5. Wireless infrared remote control to enter set points and
operating conditions.
6. De-- humidification mode that provides increased latent
removal capability by modulating the system operation and
set point temperature.
7. Fan-- only operation to provide room air circulation when no
cooling is required.
8. Diagnostics provide continuous checks of unit operation
and warns of possible malfunctions. Error messages appear
on the unit.
9. The fan speed control is user--selectable: high, medium,
low, or microprocessor controlled automatic operation
during all operating modes.
10. Automatic heating--to-- cooling changeover in the heat pump
mode. The control includes deadband to prevent rapid mode
cycling between heating and cooling.
11. Indoor coil high temperature protection is provided to detect
excessive indoor discharge temperature when the unit is in
heat pump mode.
G. Electrical Requirements:
Indoor fan motor to operate on 208 -- 230V. Power is supplied from
the outdoor unit.
H. Operating Characteristics:
The system has a minimum SEER (Seasonal Energy Efficiency
Ratio) and HSPF at AHRI conditions, as listed on the
specifications table.
I. Refrigerant Lines:
All units have refrigerant lines that can be oriented to connect from
the side of the unit. Both refrigerant lines need to be insulated.
