PART 2 -- PRODUCTS
2.01 Equipment
General:
Indoor, direct--expansion, in --ceiling cassette fan coil. The unit is
complete with cooling/heating coil, fan, fan motor, piping
connectors, electrical controls, microprocessor control system, and
integral temperature sensing.
Unit Cabinet:
The cabinet is constructed of zinc--coated steel. Fully insulated
discharge and inlet grilles is attractively styled, high--impact
polystyrene. The grille has hinges and can be opened to obtain
access to the cleanable filters, indoor fan motor and control box.
Fans:
S
The fans shall be centrifugal direct--drive blower type
with an air intake in the center of the unit and discharge
at the perimeter. Automatic, motor--driven vertical air
sweep is provided standard. Automatic motor-- driven
louvers are provided standard and are adjustable for 2, 3
or 4 -- way discharge.
S The air sweep operation is user selectable.
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 a
drain connection for hose attachment to remove condensate.
Motors:
Motors are open drip--proof, permanently lubricated ball bearing
with inherent overload protection. Fan motors are 4-- speed.
Controls:
Controls consist of a microprocessor-- based control system which
controls space temperature, determines optimum fan speed, and
runs self diagnostics. The temperature control range is 62_Fto
86_F(17_Cto30_C) in increments of 1_For1_C, and has a 46_F
Heating Mode (Heating Setback). The wireless remote controller,
has the ability to act as the temperature sensing location for room
comfort.
The unit has the following functions as a minimum:
S An automatic restart after power failures at the same
operating conditions as at the failure.
S A timer function which provides a minimum 24 -- hour
timer cycle for system Auto Start/Stop.
S Temperature--sensing controls that sense return air
temperature.
S Indoor coil freeze protection.
S Wireless infrared remote control to enter set points and
operating conditions.
S Automatic air sweep control to provide on or off
activation of air sweep louvers.
S Dehumidification mode provides increased latent
removal capability by modulating system operation and
set point temperature.
S Fan--only operation to provide room air circulation when
no cooling is required.
S Diagnostics that provides continuous checks of unit
operation and warn of possible malfunctions. Error
messages appear on the unit.
S Fan speed control is user--selectable: high, medium, low,
or microprocessor controlled automatic operation during
all operating modes.
S Automatic heating--to-- cooling changeover in the heat
pump mode. Control includes deadband to prevent rapid
mode cycling between heating and cooling.
S Indoor coil high temperature protection is provided to
detect excessive indoor discharge temperature when the
unit is in the heat pump mode.
Filters:
Unit has a filter track with factory--supplied cleanable filters.
Electrical
Requirements:
The indoor fan motor operates on 208--230V. Power is supplied
from the outdoor unit.
Operating
Characteristics:
The system has a minimum SEER (Seasonal Energy Efficiency
Ratio) and HSPF at AHRI conditions, as listed on the
specifications table.
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.
